Superior Vena Cava Anatomy Function Superior Vena Cava Syndrome Superior vena cava (svc) syndrome is a collection of clinical signs and symptoms resulting from partial or complete obstruction of blood flow through the svc. this obstruction is most commonly a result of thrombus formation or tumor infiltration of the vessel wall. the svc is formed by the junction of the left and right innominate (brachiocephalic) veins and is tasked with returning blood from. 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. its latin name is related to its large pipe appearance in cadavers, 'cava' meaning 'hollow'. the superior vena cava is very important for the function of the cardiovascular system, since it largely.

Superior Vena Cava Svc Anatomy Geeky Medics Superior vena cava syndrome . superior vena cava (svc) syndrome is a condition in which the svc gets compressed, resulting in a partial or complete blockage of blood flow. often, the underlying cause is lung cancer, non hodgkin lymphoma, or another cancer that starts in or spreads to the chest, where it forms a tumor that presses on the svc. Radiographic superior vena cava obstruction in the absence of symptoms. grade 1 (mild, ~25%): symptoms may include. edema in head or neck (vascular distention). cyanosis and or plethora. grade 2 (moderate, ~50%) edema in head or neck with functional impairment, such as: mild dysphagia. cough. mild moderate impairment of the head, jaw, or eyelid. The superior vena cava (svc) is a large, significant vein responsible for returning deoxygenated blood collected from the body to the right atrium. it is present within the superior and middle mediastinum. the superior vena cava handles the venous return of blood from structures located superior to the diaphragm. in contrast, its counterpart, the inferior vena cava, handles venous return from. Your superior vena cava and inferior vena cava have the important function of carrying oxygen poor blood to your heart’s right atrium, where it moves into your right ventricle and then to your lungs (through your pulmonary artery) to trade in carbon dioxide for oxygen. oxygenated blood comes back through your pulmonary veins to your heart’s.
