110-1). Phrenic. If CT is begun at the traditional portal venous phase (65 to 70 sec delay), the infrarenal IVC may have poor luminal enhancement owing to the relatively longer delay necessary for the venous return from the pelvis and inferior extremities to the IVC. The most common IVC anomalies are: (1) left IVC, (2) duplicated IVC, (3) azygos continuation of IVC, (4) circumaortic left renal vein, (5) retroaortic left renal vein, (6) circumcaval or retrocaval ureter, (7) duplicated right renal vein, (8) absence of infrarenal or entire IVC, (9) duplicated IVC with retroaortic right renal vein and hemiazygos continuation of the IVC, and (10) duplication of IVC with retroaortic left renal vein and azygos continuation of the IVC. The first main vein is the longest, most variable vein and is referred to as the right hepatic vein. First, those corresponding to the anterior visceral branches of the aorta form the portal vein, which passes into the liver at the porta hepatis. Kim Bengochea, Regis University, Denver, Author: Parietal tributaries: Lumbar veins (vv. The current literature consistently describes mortality rates of 50% to 70% for injuries to the superior mesenteric vein… The diameter of the main hepatic veins on average 12.3 mm, and back — 4.8 mm. Hepatic portal vein. naturalghost. Anatomical variations or obstruction of the IVC can make these procedures difficult. “I would honestly say that Kenhub cut my study time in half.” Superior pancreaticoduodenal veinjoins the portal vein behind the very first part of duodenum. A, Contrast-enhanced CT axial images show infrarenal IVC (I) and a smaller duplicated left IVC (arrow) that arises from the left iliac vein. The venous congestion caused by the tumor can cause acute organ failure of the liver, kidneys, and other organs depending on its location, growth rate, and the development of bland thrombus aggravating the problem. T8: paired inferi… They drain the lower limbs and gluteal region. Gravity. We recommend postcontrast imaging using a 3D T1-weighted gradient sequence (e.g., LAVA, THRIVE, or VIBE). Etiology and Pathophysiology (Including any Special Anatomic Considerations). Circumaortic left renal vein: A circumaortic left renal vein may be difficult to see on Doppler imaging because the two veins do not join the IVC at the same level. Circumaortic left renal vein: There are two left renal veins. Azygos continuation of IVC: The infrarenal portion of IVC receives blood from the renal veins. The circumaortic venous ring and retroaortic left renal vein are related to aberrant development of the renal segment. Genetic factors may play a role in IVC anomalies because having a first-degree relative with an IVC anatomic anomaly is considered a risk factor. Obstruction of the superior vena cava (SVC) or inferior vena cava (IVC) is most commonly an acquired condition, typically caused by malignancy, benign conditions such as mediastinal fibrosis, and iatrogenic causes such as venous catheterization. left posterior 8 th-11 th intercostal veins; left superior phrenic vein left renal vein (occasionally) IVC (occasionally) Variant anatomy. Deviations in the complex embryogenesis of the IVC may result in an overall 4% of anatomic variants in the general population. Apart from the common iliac veins, there are 6 pairs of veins, 2 singular veins and a hepatic group of veins, which drain into the inferior cava directly. The inferior vena cava (IVC) drains venous blood from the lower trunk, abdomen,pelvis and lower limbs to the right atrium of the heart. It can also occur in patients with renal cell carcinoma, a malignancy of the kidney. One of the most common causes of neoplastic invasion of the IVC lumen is the renal cell carcinoma (RCC) that can be seen invading the IVC through the renal vein in 4% to 10% of the cases. Early in embryogenesis, there are two renal veins for each kidney: ventral and dorsal. The inferior vena cava anatomy is essential due to the vein’s great drainage area, which also makes it a hot topic for anatomy exams. Grounded on academic literature and research, validated by experts, and trusted by more than 1 million users. Hepatic portal system. If the entire IVC is absent, the anterior paravertebral collateral vessels convey the blood return to the azygos and hemiazygos veins. Tributaries of Inferior Vena Cava. Obtain a complete anatomic assessment with CT or MRI of the relevant location (i.e., chest, abdomen, and/or pelvis). The left IVC then passes posterior to the diaphragmatic crura and continues into the thorax as the hemiazygos vein. It was established that in past hepatic part of IVC fall from 7 to 23 veins. The right IVC (I) continues through the azygos vein (A) above the level of the renal veins. Retroaortic left renal vein: A retroaortic left renal vein may be difficult to see on Doppler imaging. Tributaries. Charlotte O'Leary BSc, MBChB At the T8 level hepatic veins, inferior phrenic vein At the L1 level right suprarenal vein, renal veins At the L2 level right gonadal vein At the L1–L5 level lumbar veins At the L5 level common iliac veins All the lumbar veins and hepatic veins usually drain directly into the inferior vena cava.On the left, they drain into the renal vein which in turn drains into the inferior vena cava.On the right, the gonadal veins and suprarenal veins drain into the inferior vena cava directly. Various diagnostic and therapeutic procedures of the right side of the heart and the systemic venous system have increased the need for ready access to the inferior vena cava (IVC) through the transfemoral route. Posterior: IVC. IVC duplication (infrarenal). The shape of the IVC varies from round to ovoid or even flat depending on a multitude of factors such as intrathoracic pressure, blood volume status, or the presence of congestive heart failure. B, Sagittal reformat of the same study shows IVC segments with different luminal enhancement due to the normally observed different timing of the contrast return. Some problems that can develop within the inferior vena cava include compression and thrombosis. Some lumbar veins empty into the IVC as well as into the ascending lumbar veins described in table 20.11. The IVC was to the right of the spine, smaller than normal , and ended abruptly a short distance above the right renal vein at the level of the first lumbar vertebra . The origin of a second, posterior left renal vein is visualized (arrowhead). It communicates with the vertebral venous plexuses. With the absence of infrarenal IVC or entire IVC, patients may present with venous insufficiency of the lower extremities or idiopathic deep venous thrombosis. Inferior Vena Cava Tributaries. Although the diagnosis of IVC anatomic aberrations may be suspected with abdominal ultrasonography, the assessment is usually limited due to their deep location, difficult insonation angle for Doppler studies, and/or the presence of bowel gas that may obscure key segments of the veins. The IVC gets the following tributaries: 1. D, Sagittal MIP reformat shows the azygos (A) continuation of the right IVC and how it connects to the SVC (S) through the azygos arch. Treatment involves anticoagulation and thrombolytic therapy and may involve liver transplantation if the liver disease progresses to decompensated cirrhosis. IVC and renal vein anatomic variants have minimal increased risk for medical complications such as thrombus or embolism, but are particularly important to identify in patients planning to undergo surgical or percutaneous interventions because their identification can aid in procedure planning and reduce likelihood of complications. Lumbar veins. Provide the information when requesting an imaging examination because this may aid in selecting the proper protocol for the imaging examination. Therefore, this syndrome can result in liver disease if not treated. Inform the patient and other physicians of the presence and kind of anatomic variant. In either case, the iliac veins join to form enlarged ascending lumbar veins. CT is a very useful modality to evaluate IVC anomalies because of its ability to generate volumetric data quickly for multiplanar reformation. The right renal vein is 2.5 cm long and is found posterior to the second part of the duodenum. Composed behind the neck of pancreas, the portal vein is unified by superior mesenteric veinand splenic vein in the level of L2 It runs upward and a little to the right supporting the neck of pancreas, then ascends posterior to the very first part of the duodenumto goes into the right free edge of the lesser omentum. The IVC is formed from the two common iliac veins at the L5 vertebral level. The hepatic segment may not be truly absent. If the tumor obstructs the hepatic segment of the IVC, it may manifest as, Clinical Techniques of Cardiac Magnetic Resonance Imaging: Morphology, Perfusion, and Viability, Basic Three-Dimensional Postprocessing in Computed Tomographic and Magnetic Resonance Angiography, Indications and Patient Selection in Obstructive Coronary Disease, Advanced Three-Dimensional Postprocessing in Computed Tomographic and Magnetic Resonance Angiography, Radiopharmaceuticals and Radiation Dose Considerations in Cardiac Positron Emission Tomography and PET/CT, Renal Arteries: Computed Tomographic and Magnetic Resonance Angiography, Methods for Cardiac Magnetic Resonance Imaging, CARDIOVASCULAR IMAGING CARDIOVASCULAR IMAGING. In the event of chronic occlusion, collateral pathways must develop to maintain venous drainage. Left IVC: The infrarenal IVC is located to the left of the abdominal aorta, then it joins the left renal vein which then crosses anterior to the abdominal aorta and along with the right renal vein forms the normal right-sided prerenal IVC. Tributaries. The very first and 2nd lumbar veins finish in the ascending lumbar vein. Parietal inflows are formed in the walls of the abdominal cavity and pelvic cavity. Reading time: 7 minutes. “Black blood” MRI pulse sequences, in which the vessel lumen is dark secondary to the washout phenomenon (also termed flow void) associated with moving spins (i.e., flowing blood that washes out of the imaging slice prior to sampling of the echo). Three main hepatic veins and some minor hepatic veins drain the liver and join the inferior vena cava. The suprarenal segment is formed via a subcardinal-hepatic anastomosis. FIGURE 110-3 Azygos-hemiazygos continuation of the IVC with duplication of the infrarenal IVC. The right inferior vena cava was formed in the usual way by the junction of the right and left common iliac veins, and from thence upward it pursued the ordinary course of the inferior vena cava on the right of the aorta. Flashcards. B, CECT of the abdomen shows the posterior left renal vein (arrow) crossing behind the abdominal aorta 1 cm caudad to the anterior left renal vein. Nutcracker Syndrome occurs when the left renal vein is compressed between the superior mesenteric artery and the aorta. Test. FIGURE 110-1 Normal IVC. The emergence of CT and MRI for vascular imaging has facilitated the transitioning of x-ray catheter angiography from merely a diagnostic tool to a viable less invasive percutaneous therapeutic replacement for complex open surgical interventions. Occasionally IVC tumors may cause embolism to the pulmonary arteries and produce cardiorespiratory symptoms including chest pain, tachycardia, and dyspnea. With partial or complete absence of the IVC, large gonadal and parauterine veins can be seen. PLAY. In the thorax, the hemiazygos vein may have any of these different drainage pathways: (1) it crosses posterior to the aorta at about T8 to T9 to join the rudimentary azygos vein; (2) it joins a persistent left SVC and drains into the coronary vein; (3) an accessory hemiazygos continues to join the left brachiocephalic vein. Visceral tributaries of the inferior vena cava: a) adrenal veins b) inferior diaphragmatic veins c) testicular vein d) renal vein e) lumbar veins 493. There are usually five pairs of lumbar veins. ... Tributaries to the inferior vena cava include the following veins: common iliac veins, lumbar veins, right testicular or ovarian vein, renal veins, right suprarenal vein, inferior phrenic veins, and ; hepatic veins. Contrast-enhanced CT shows two IVC—one on each side of the aorta. Learn. In 63% of cases betwe … Right adrenocortical carcinomas directly invade the IVC through the adrenal veins. Last reviewed: December 21, 2020 The IVC has a retroperitoneal course within the abdominal cavity. 3. Similar anatomic detail can be seen on MRI as is seen on CT. Steady-state free precession (SSFP; also termed b-FFE, Philips Medical Systems; FIESTA, General Electric Healthcare; True-FISP, Siemens Medical Solutions) pulse sequences are “bright blood” techniques that are particularly good for illustrating abdominal veins. The tributaries of the inferior vena cava differ from the branches of the aorta in two respects. The proximal right ureter courses posterior to the IVC, emerges to the right of the aorta, and lies anterior to the right iliac vessel. Gadolinium-enhanced MRI is arguably the most reliable method to assess vascular patency. Signs and symptoms include abdominal pain, jaundice (yellowing of the skin), hepatomegaly (enlarged liver) and ascites (fluid in the peritoneal cavity). Introduction to the musculoskeletal system, Renal Vein Thrombosis Treatment & Management, Lumbar veins (posterior view) - Yousun Koh, Right ovarian vein (anterior view) - Irina Münstermann, Renal vein (anterior view) - Begoña Rodriguez, Hepatic vein (anterior view) - Begoña Rodriguez. 492. STUDY. 5-6 branches unite to form the main Renal Veins The renal veins are anterior to the renal arteries on either side of the abdomen. The right IVC joins the right renal vein, which crosses posterior to the aorta to drain in the left IVC. Are you ready to learn? It is located posterior to the splenic vein and the body of the pancreas. Major tributaries such as the renal and adrenal veins have been studied extensively; however, tributaries of the infra-renal segment of the inferior vena cava (IVC) have not been given much attention. It has a short intra-thoracic course before draining into the right atrium at the inferior cavoatrial junction. Retroaortic left renal vein: The renal vein crosses posterior to the aorta to join the IVC. It runs along the right side of the vertebral column with the aorta lying on the left. It is formed by the union of the common iliac veins at the level of the body of L5. Azygos-hemiazygos continuation of the IVC with duplication of the infrarenal IVC. 110-3). As it ascends the abdominal cavity, the IVC picks up blood from numerous tributaries in the order listed here (fig. Technique: To study the anatomy of the IVC, the CT protocol should include imaging of the chest, abdomen, and pelvis with the use of an intravenous iodinated contrast agent. Anatomic variants of the IVC can be seen in association with other anomalies. Are you ready to learn? The patients typically present lower extremity edema and subcutaneous collateral veins in the abdominal wall. Because MRI does not expose the patient to ionizing radiation, it is possible to acquire multiple series of images postcontrast injection, including axial, coronal, and sagittal planes with different timing for more homogeneous luminal enhancement. Occasionally, a palpable mass may be felt in the right iliac fossa. In the tributaries, but can develop secondary to an obstructive process that reduces IVC flow What syndrome is a common cause of IVC thrombus? With left IVC, the IVC is positioned to the left of the abdominal aorta. A useful mnemonic to remember the tributaries of the inferior vena cava is: I Like To Rise So High Mnemonic I: common iliac veins L: lumbar veins T: right testicular (gonadal) vein R: renal veins S: suprarenal veins H: hepatic veins Almost 10% of these patients with a coexisting thrombophilia have congenital absence of the IVC. Version 2.69 36790-4MRA Inferior vena cava + tributariesActive Term Description This study is used to image the inferior vena cava (IVC) and its tributaries. It also joins with the azygos vein (which runs on the right side of the vertebral column) and venous plexuses next to the spinal cord. MRI risks are related to those associated with the magnetic field but also to that of intravenous contrast agent administration if performed. As the right ovarian vein is a tributary of the inferior vena cava, the thrombus may embolise and travel to the lungs via the inferior vena cava and right atrium. Version 2.69 36790-4MRA Inferior vena cava + tributariesActive Term Description This study is used to image the inferior vena cava (IVC) and its tributaries. Knowing the tributaries of the inferior vena cava can be important in the surgical field. Recommendations for clinicians are. The left IVC joins the left renal vein which then crosses posterior to the aorta to join the right IVC. Primary IVC tumors (leiomyosarcomas) are very rare with only one large series published in the literature. Treatment includes anticoagulation therapy and antibiotics. Only gold members can continue reading. FIGURE 110-2 IVC duplication (infrarenal). A circumcaval ureter is also typically not seen on ultrasound images unless there is hydroureter. Like with the ovarian vein, it can also cause a PE, so prophylaxis with anticoagulants is usually carried out. Approximately 5% of patients younger than 30 years with idiopathic deep venous thrombosis show IVC absence on CT. Intravenous contrast media may be administered to confirm venous patency, presence of a stenosis, visualization of collaterals, and/or venous tumor invasion. Created by. Examples of this technique include T4-weighted spin echo and single shot T2-weighted imaging (e.g., SSFSE, HASTE), which can provide excellent anatomic assessment almost free of motion artifacts. The compression performed during a standard abdominal ultrasonographic examination may also cause collapse of some veins, making the anatomic assessment even more limited. The first lumbar vein occasionally drains into the inferior vena cava but usually drains into the second lumbar vein, the ascending lumbar vein or the azygos vein. The IVC receives a number of tributaries including common iliac, lumbar, renal, right adrenal, and hepatic veins. Log In or, Click to share on Twitter (Opens in new window), Click to share on Facebook (Opens in new window), Click to share on Google+ (Opens in new window), on Inferior Vena Cava and Its Main Tributaries. Here, they are connected by the ascending lumbar vein, which runs anterior to the transverse processes of the lumbar vertebrae. Kenhub. Because the inferior vena cava is located to the right of the midline, drainage of the tributaries is not always symmetrical. The foot is drained primarily by the dorsal venous arch, which crosses the top of the foot not far from the base of … Then, the most caudal segment of the right supracardinal vein becomes the infrarenal vena cava. Many one-way venous valves help to move blood through the veins of the lower extremities against the pull of gravity. I Like To Rise So High Iliac Lumbar Testicular Renal Suprarenal Hepatic vein. Treatment also involves a reduction in proteinuria, for patients with nephrotic syndrome, with ACE inhibitors. C, Thick coronal MIP reformat shows the duplicated infrarenal IVC with the left (arrow) draining into the left renal vein and crossing behind the aorta (black arrow). Hepatic portal system. The results of the anatomical study of the inferior vena cava (IVC) and its tributaries on 27 fresh cadavers were analysed. Multiple other retroperitoneal tumors can compress and invade the IVC, including lymphomas, metastasis of gonadal or uterine tumors, pheochromocytomas, and other retroperitoneal sarcomas. SSFP, especially performed in cine mode, is useful for identification of central venous thrombosis. The IVC lies between the liver and the diaphragm and cephalad courses medially to … – At the level of the renal veins, the second lumbar vein usually joins the inferior vena cava but it may occasionally drain into the third lumbar vein or the ascending lumbar vein. The inferior vena cava brings blood to the heart from the lower body. It then joins the superior vena cava at its normal location in the right paratracheal space. The results of the anatomical study of the inferior vena cava (IVC) and its tributaries on 27 fresh cadavers were analysed. Our engaging videos, interactive quizzes, in-depth articles and HD atlas are here to get you top results faster. The renal segment forms via anastomosis of the right supra-subcardinal and post-subcardinal veins. They can arise in any segment of the IVC and can extend intraluminally to the right atrium of the heart. The remaining congenital IVC anomalies are rare. X-ray catheter angiography studies provide limited anatomic information. Every common iliac vein gets an iliolumbar vein. Duplication of IVC with retroaortic left renal vein and azygos continuation of IVC: There are two infrarenal IVCs. The hepatic and right adrenal veins drain directly into the right atrium. Two thirds of the leiomyosarcomas appear predominantly as extraluminal growth and the other one third appear mostly as intraluminal tumors. Azygos continuation, in particular, can be associated with significant congenital heart disease. FIGURE 110-4 Circumaortic left renal vein. It is recommended to ensure that there is at least a 2-minute delay between intravenous contrast administration and CT scanning because this will improve the likelihood for homogeneous enhancement of the IVC. The patients typically present lower extremity edema and subcutaneous collateral veins in the abdominal wall. The superior anatomic assessment provided by MRI or MDCT of the abdomen and pelvis makes them the modalities of choice at the time of making the final diagnosis. CHAPTER 110 Inferior Vena Cava and Its Main Tributaries, Carlos Cuevas, Manjiri Dighe, Mariam Moshiri. If the suprarenal IVC is present, it receives blood from the renal veins. Learning anatomy is a massive undertaking, and we're here to help you pass with flying colours. Primary IVC tumors (leiomyosarcomas) are very rare with only one large series published in the literature.5 It is more common to see tumors invading the IVC through its tributary veins arising from separate abdominal organs. The common iliac veins join at the level of L5 to form the inferior vena cava and can thus be considered its tributaries of origin. B, CECT at a higher level demonstrates the absence of the intrahepatic portion of the IVC, which continues through the azygos vein (A) in retrocrural location. The new phased array coils built with 12 and 16 channels can deliver better coverage of the abdomen and pelvis and provide increased signal-to-noise ratio. It runs along the right side of the vertebral column with the aorta lying on the left. Branches of abdominal aorta: a) lumbar arteries b) inferior epigastric arteries c) middle adrenal arteries d) superior diaphragmatic arteries a) lumbar arteries b) inferior epigastric arteries c) middle The inferior vena cava is responsible for the venous drainage of all structures below the diaphragm. This can cause venous congestion, which can increase venous pressure and damage the liver. The suprarenal IVC, moreover, may show heterogeneous enhancement because of mixing of the contrast bolus returning from the renal veins. The infrarenal segment arises from the right supracardinal vein. The IVC extends from the confluence of the common iliac veins at the level of L5 vertebral body, to the right atrium of the heart in right prevertebral location, next to the abdominal aorta and is surrounded by a rich network of lymphatic vessels (Fig. Although the diagnosis of left renal vein variants is easy to detect, in the right kidney the findings of a double vein can be more subtle and sometimes may be overviewed. Read more. Budd-Chiari in the hepatic veins extending into the IVC. Terms in this set (16) Inferior Vena Cava.
