The inferior vena cava (IVC) is the main conduit of venous return to the right atrium from the lower extremities and abdominal viscera.It can be a source of critical information for referring clinicians, and recognition of IVC variants and pathologic characteristics can help guide patient treatment. It collects blood from veins serving the tissues inferior to the heart and returns this blood to the right atrium of the heart. The name derives from Latin: vena, "vein", cavus, "hollow". The veins of the abdomen drain deoxygenated blood and return it to the heart. After coming up through the diaphragm it passes almost immediately into the lower part of the right atrium. Here’s the inferior vena cave. It then ascends the posterior abdominal wall, to the right side of the aorta and the bodies of the L3-L5 vertebrae. The IVC in … The inferior vena cava (IVC) begins at the confluence of the common iliac veins and ascends on the right side of the vertebral column, passes through the tendinous portion of the diaphragm, and after a short course (approximately 2.5 cm) in the chest it terminates in the right atrium at the level of T9. These veins come together in the abdomen, helping to move blood from the lower limbs back up to the heart. Image showing an inferior vena cava filter in its position, One of two veinous trunks bringing deoxygenated blood back to the heart. J Invasive Cardiol. The inferior vena cava (IVC) begins at the confluence of the common iliac veins and ascends on the right side of the vertebral column, passes through the tendinous portion of the diaphragm, and after a short course (approximately 2.5 cm) in the chest it terminates in the right atrium at the level of T9. Inferior Vena Cava Disorders 1. ANATOMY OF THE ABDOMINAL AND PELVIC VEINS. It runs along the right side of the vertebral column with the aorta lying laterally on the left. It is formed by the union of the common iliac veins at the level of the body of L5. I hope you find this anatomy guide helpful. anatomy of human abdominal vein system. The anatomy of the inferior vena cava can be seen in the picture below. Roberto Iezzi, Alessandro Posa, Francesca Carchesio, Riccardo Manfredi, Multidetector-row CT imaging evaluation of superior and inferior vena cava normal anatomy and caval variants: Report of our cases and literature review with embryologic correlation, Phlebology: The Journal of Venous Disease, 10.1177/0268355518774964, 34, 2, (77-87), (2018). On the right, the gonadal veins and suprarenal veins drain into the inferior vena cava directly. The purpose of this article is to increase "The eustachian valve is an embryologic remnant of the valve of the inferior vena cava." Although the vena cava is very large in diameter, its walls are incredibly thin due to the low pressure exerted by venous blood. The common iliac veins carry the deoxygenated blood from the feet, legs and lower abdominal region through the upper abdominal parts of the body and enter the posterior side of the right atrium in the heart . Dari sana darah dipompa ke paru-paru untuk mendapatkan oksigen sebelum pergi ke sisi kiri jantung untuk dipompa kembali ke tubuh. Anatomically this usually occurs at the L5 vertebral level. The IVC handles blood from the lower body while the other vein, known as the superior vena cava, carries the blood circulating in the upper half of the body. After the closure of the foramen ovale, it does not have a specific function. Although the vena cava is very large in diameter, its walls are incredibly thin due to the low pressure exerted by venous blood. Together, the venae cavae (in addition to the coronary sinus, which carries blood from the muscle of the heart itself) form the venous counterparts of the aorta. Anatomynote.com found Inferior Vena Cava Diagram from plenty of anatomical pictures on the internet.

At the level of T4, the superior vena cava receives the azygous vein, which drains the upper lumbar region and thoracic wall. It’s possible for the IVC to have a congenital difference, and these are difficult to detect. Often a person won’t have any symptoms to signal a defect in the IVC. This image added by admin. Truty MJ, Bower TC. Summary – Superior vs Inferior Vena Cava. What is inferior vena cava. The IVC lies along the right anterolateral aspect of the vertebral column and passes through the central tendon of the diaphragm around the T8 vertebral level. GEZA MOZES, PETER GLOVICZKI, in The Vein Book, 2007. The inferior vena cava is actually made of two large veins known as the common iliac veins. Vena cava inferior (juga dikenal sebagai IVC atau vena cava posterior) adalah vena besar yang membawa darah dari batang tubuh dan tubuh bagian bawah ke sisi kanan jantung. 2018;43(8):2130-2149. doi:10.1007/s00261-017-1430-y, Petik B. Clin Anat. Anatomically this usually occurs at the L5 vertebral level. The inferior vena cava begins as the left and right common iliac veins behind the abdomen unite, at about the level of L5. Instead of valves, the pressure from breathing and the contraction of the diaphragm as the lungs fill with air helps to pull the blood forward from the IVC all the way up to the heart. It is formed by the union of the right and left brachiocephalic veins – which provide venous drainage of the head, neck, and upper limbs. The inferior vena cava (IVC) is the main conduit of venous return to the right atrium from the lower extremities and abdominal viscera. Compression of the inferior vena cava by right renal cysts: an unusual cause of IVC and/or iliofemoral thrombosis with pulmonary embolism in autosomal dominant polycystic kidney disease. [1][3] It passes to the right of the descending aorta.[3]. It runs alongside the abdominal aorta, but there are several important differences between their branches and tributaries which make perfect fodder for trick questions in exams! Rao B, Duran C, Steigner ML, Rybicki FJ. Shown are the hepatic veins, inferior vena cava, aorta, iliac veins, and inferior epigastric veins. Medline, Google Scholar; 35 Kew MC, McKnight A, Hodkinson J, Bukofzer S, Esser JD. It also joins with the azygos vein and venous plexuses next to the spinal cord. Superior vena cava, inferior vena cava, azygos vein and their tributaries. Inferior vena cava. Inferior Vena Cava; Jump To… Overview . Quick Anatomy . We think this is the most useful anatomy picture that you need. The IVC ascends through the posterior abdominal region on the right side of the abdominal aorta. Lorem ipsum dolor sit amet, sapien platea morbi dolor lacus nunc, nunc ullamcorper. [1][2] It passes through the thoracic diaphragm at the caval opening at the level of T8 - T9. It collects blood from veins serving the tissues inferior to the heart and returns this blood to the right atrium of the heart. The inferior vena cava is a large vein that carries deoxygenated blood from the feet, legs, thighs, pelvis, abdomen and delivers into the right atrium of the heart. Typical sources of external pressure are an enlarged aorta (abdominal aortic aneurysm), the gravid uterus (aortocaval compression syndrome) and abdominal malignancies, such as colorectal cancer, renal cell carcinoma and ovarian cancer. The inferior vena cava is formed by the joining of the common iliac veins which meet a little below the small of the back. In transposition of the great arteries the inferior vena cava may lie on the left. Depending on the severity and frequency of the blood clots, IVC filters can be left in permanently or removed once the risk of clots forming and traveling to the lungs has passed. A few veins merge and drain into the IVC before it makes its way up to the heart, including the left renal vein. Superior vena cava obstruction can occur either due to external compression or from an occlusion within the vessel lumen itself. The inferior vena cava is formed by the coming together of the two major veins from the legs, the common iliac veins, at the level of the fifth lumbar vertebra, just below the small of the back. Objectives At the end of this presentation you will be able to: Describe the anatomy & physiology of the IVC Understand the pathologic conditions & anatomic variants of the Inferior Vena Cava Identify and discuss the Theory of Virchow’s Triad Define Inferior Vena Cava filter placement and uses White arrows indicate valid blood flow. Inferior Vena Cava. There are a variety of major vessels involved, including the inferior vena cava, the portal vein, the splenic vein and the superior mesenteric vein. Reading Time: Overview; Gross Anatomy; Clinical Anatomy; Quick Anatomy; ... Clinical Anatomy. The inferior vena cava runs along the vertebral bodies in the spine, and is formed by the joining of two leg veins in the lower body which … It goes into the right atrium of the heart, in through the back side. The superior vena cava is a thin-walled, low pressure vessel which makes it vulnerable to compression. De-oxygenated blood is carried from the legs and lower torso, and is emptied from the inferior vena cava into the right atrium of the heart, which is located on the lower posterior (back) side of the heart. The IVC has a retroperitoneal course within the abdominal cavity. 2016;7(4):229-232. To see the inferior vena cava, we’ll move the diaphragm downward, and move the heart to the left. In this article we shall consider the anatomy of the abdominal veins - their anatomical course, tributaries and clinical correlations. for more anatomy content please follow us and visit our website: www.anatomynote.com. An IVC filter stops blood clots that form in the veins of the lower half of the body, or someone who suffers from deep vein thrombosis, from having those clots reach the lungs.. The valve of the inferior vena cava is a rudimentary fold present at the anteroinferior margin of the IVC orifice within the right atrium. Anomalies in the course and drainage of the Inferior Vena Cava (IVC) may complicate normal functioning, correct diagnosis, and therapeutic interventions within the abdomen. Below the liver, the IVC lies behind the duodenum and head of the pancreas as a retroperitoneal structure passing upward behind the foramen of Winslow posterior to the right hilar structures of the liver. The superior vena cava is located in the upper chest region and is formed by the joining of the brachiocephalic veins. [1] 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. It is a large retroperitoneal vein that lies posterior to the abdominal cavity and runs along the right side of the vertebral column. The inferior vena cava (IVC) is the largest vein in the body. It enters separately form the superior vena cava, which is here. Anatomically this usually occurs at the L5 vertebral level. The IVC is one of the largest veins in the body, which is helpful for the large volume of blood it’s responsible for carrying. These veins come together in the abdomen, helping to move blood from the lower limbs back up to the heart. It runs alongside the abdominal aorta, but there are several important differences between their branches and tributaries which make perfect fodder for trick questions in exams! The inferior vena cava is the largest vein in the human body. The IVC ascends from the front of the vertebral column on the right side of the aorta. [1] On the left, they drain into the renal vein which in turn drains into the inferior vena cava. Inferior Vena Cava: This vein brings de-oxygenated blood from the lower body regions (legs, back, abdomen and pelvis) to the right atrium. The inferior vena cava arises from the fusion of the right and left common iliac veins at the level of the fifth lumbar vertebra (L5), just inferior to the bifurcation of the abdominal aorta. To prevent the blood from moving back into the body, valves made up of tissue in the vein close as the blood through it. The inferior vena cava (IVC) is a large retroperitoneal vessel formed by the confluence of the right and left common iliac veins. In the upper abdomen the IVC is located posterior to the duodenum, the head and neck of the pancreas, the lesser … Symptoms, when they do occur, include vague low back or abdominal pain., Some variations of the IVC are the left IVC, which happens when the left renal vein joins the left IVC but then crosses in front of the aorta before going into the right atrium if the heart. Diagnosis of left sided inferior vena cava is important for: planning of vascular procedures like portosystemic shunts; abdominal aortic aneurysm repair • Anatomy photo:40:13-0101 at the SUNY Downstate Medical Center - "Posterior Abdominal Wall: Tributaries to the Inferior Vena Cava" We think this is the most useful anatomy picture that you need. Figure 02: Superior and Inferior Vena Cava. "During fetal life, the eustachian valve directs oxygen-rich blood from the inferior vena cava (IVC) toward the foramen ovale and away from the tricuspid valve. [6], The inferior vena cava is a vein. Inferior Vena Cava Thrombosis or Occlusion IVC thrombosis may result from innate thrombogenicity of the filter, trapped emboli within the filter, or propagation of thrombus through the venous system up to and including the filter (see Figure 47.2). The inferior vena cava is formed by the coming together of the two major veins from the legs, the common iliac veins, at the level of the fifth lumbar vertebra, just below the small of the back. Superior vena cava (Vena cava superior) The superior vena cava (SVC, also known as the cava or cva) is a short, but large diameter vein located in the anterior right superior mediastinum. Since the inferior vena cava is primarily a right-sided structure, unconscious pregnant women should be turned on to their left side (the recovery position), to relieve pressure on it and facilitate venous return[citation needed]. But the anatomy of the IVC vein is slightly different. Several veins drain into the inferior vena cava: The IVC has a retroperitoneal course within the abdominal cavity. The inferior vena cava (or IVC) is a large vein that carries the deoxygenated blood from the lower and middle body into the right atrium of the heart.
