Inferior vena cava syndrome (IVCS) is a very rare constellation of symptoms resulting from either obstruction or stenosis of the inferior vena cava. It can be caused by physical invasion or compression by a pathological process, or by thrombosis within the vein itself. It can also occur during pregnancy. Symptoms including high venous pressure ...
The recovery position is designed to prevent suffocation through obstruction of the airway, which can occur in unconscious supine patients. The supine patient is at risk of airway obstruction from two routes: Mechanical obstruction: In this instance, a physical object obstructs the airway of the patient.
Aortocaval compression syndrome, also known as supine hypotensive syndrome, is compression of the abdominal aorta and inferior vena cava by the gravid uterus when a pregnant woman lies on her back, i.e. in the supine position.
Vascular snares are used to retrieve inferior vena cava filters, lost guide wires, or broken central venous catheters. [1] Vascular snaring is a component technique in endovascular aneurysm repair in some devices. [citation needed]
There are case reports of the inferior vena cava being compressed by the iliac arteries or right-sided compression syndromes, but the vast majority are on the left side. While this is the suspected cause of the syndrome, the left iliac vein is frequently seen to be compressed in asymptomatic patients, and considered an anatomic variant.
The inferior vena cava is a large vein that carries the deoxygenated blood from the lower and middle body into the right atrium of the heart. It is formed by the joining of the right and the left common iliac veins , usually at the level of the fifth lumbar vertebra .
[7] Intravascular stents are a treatment method for Congenital Stenosis of the Vena Cava. [8] Expandable metallic stents have been used as part of a procedure to dilate and maintain stenotic vena cava. [8] Experiments carried out on mongrel dogs resulted in some failures for dilation and early migration, and occlusion complications in patients.
The vena cava is to the right of the midline and therefore the left common iliac vein is longer than the right. [2] The left common iliac vein occasionally travels upwards to the left of the aorta to the level of the kidney, where it receives the left renal vein and crosses in front of the aorta to join the inferior vena cava.
