What is an interrupted inferior vena cava?
What is an interrupted inferior vena cava?
Interrupted inferior vena cava (IVC) is a rare congenital abnormality often combined with cardiovascular and visceral malformations. We report the case of a 63-year-old male who presented in complete heart block with periodic absence of an escape rhythm requiring emergency temporary pacing.
Does azygos vein drain into IVC?
It passes through the diaphragm, reaches the mediastinum and finally drains into the superior vena cava. The azygos venous system has many anastomoses with inferior vena cava and vertebral venous plexuses….Azygos vein.

What is the continuation of which vein is the azygos vein?
inferior vena cava
The azygos vein joins the superior vena cava (SVC) at the normal location in the right paratracheal space. Other arrangements in the duplicated inferior vena cava drainage can be found, such as: double IVC with retroaortic right renal vein and hemiazygos continuation of the IVC.
What part of the heart does the IVC drain into?
right atrium
The IVC enters the right atrium of the heart after coursing through the diaphragm, entering the posterior inferior aspect of the atrium. The IVC enters the right atrium inferior to the entrance of the superior vena cava (SVC).
What does IVC filter stand for?
An inferior vena cava (IVC) filter is a small device that can stop blood clots from going up into the lungs. The inferior vena cava is a large vein in the middle of your body.
Is the azygos vein on the right?
The azygos vein is a unilateral vessel that ascends in the thorax to the right of the vertebral column, carrying deoxygenated blood from the posterior chest and abdominal walls.
Where does the azygos vein empty?
The azygos vein originates at the junction of the right ascending lumbar and subcostal veins, entering the chest through the aortic hiatus. It ascends along the anterolateral surface of the thoracic vertebrae and arches ventrally to the right main bronchus at T5–T6, draining into the SVC.
How is azygos vein formed?
It is formed by the union of the ascending lumbar veins with the right subcostal veins at the level of the 12th thoracic vertebra, ascending in the posterior mediastinum, and arching over the right main bronchus posteriorly at the root of the right lung to join the superior vena cava.
What is the main function of the inferior vena cava?
The inferior vena cava carries blood from the legs, feet, and organs in the abdomen and pelvis. The vena cava is the largest vein in the body.
Can you live without an inferior vena cava?
Absence of the inferior vena cava is a rare vascular anomaly, which usually remains asymptomatic in childhood. It is recognized as the risk factor for deep venous thrombosis, since the collateral circulation does not provide adequate drainage of the lower limbs.
Is the infrahepatic IVC interrupted with azygos continuation?
Infrahepatic IVC interruption with azygos continuation is a rare congenital anomaly especially when it is not associated with congenital heart disease.
What is the azygos continuation of the inferior vena cava?
Azygos continuation of the inferior vena cava (also known as the absence of the hepatic segment of the IVC with azygos continuation) is an uncommon vascular anomaly and is a cause of a dilated azygos vein. Spelling it “azygous” when referring to the vein is incorrect, regardless of whether British or American English 4.
Where does azygos and hemiazygos continuation take place?
Interruption of the inferior vena cava (IVC) with azygos continuation is a rare congenital anomaly, in which the IVC is interrupted below the hepatic vein and venous return beyond this point is restored by the dilated azygos and hemiazygos veins draining into the superior vena cava.
When to use interrupted inferior vena cava ( IVC )?
Interrupted inferior vena cava (IVC) is a rare congenital abnormality often combined with cardiovascular and visceral malformations. We report the case of a 63-year-old male who presented in complete heart block with periodic absence of an escape rhythm requiring emergency temporary pacing.
