Superior vena cava - Wikipedia, the free encyclopedia The superior vena cava (SVC) is a large but short vein that carries de-oxygenated blood from the upper half of the body to the heart's right atrium. It is formed by the left and right brachiocephalic veins (also referred to as the innominate veins) which receive blood from the upper limbs and the head and neck.

Inferior vena cava - Wikipedia, the free encyclopedia The inferior vena cava (or IVC) is a large vein that carries de-oxygenated blood from the lower half of the body into the heart. The vein that carries de-oxygenated blood from the upper half of the body is the superior vena cava. Since the inferior vena cava is primarily a right-sided structure, unconconscious pregnant females should be turned on to their left side (the recovery position), to relieve pressure on it and facilitate venous return. en.wikipedia.org /wiki/Inferior_vena_cava   (547 words)

Superior Vena Cava Syndrome:   (Site not responding. Last check: 2007-11-07) Superior vena cava syndrome (SVCS) is a collection of symptoms caused by the partial blockage of the vein that carries blood from the head, neck, chest, and arms to the heart. Superior vena cava syndrome refers to blockage of the superior vena cava, while the squeezing of the trachea (windpipe) is called superior mediastinal syndrome. Superior vena cava syndrome is rare in children and appears in 12% of children with cancer in the chest. www.acor.org /cnet/62844.html   (2388 words)

s030122a - Superior Vena Cava Syndrome - Etiology & Diagnosis Obstruction of the superior vena cava and trachea from benign goiters. Abstract: Superior vena cava (SVC) syndrome is a critical condition in which an intrathoracic mass lesion compresses the SVC and promotes the development of head and upper body edema and cyanosis. SVC bypass should be considered early in the course of patients with profound cerebral or laryngeal edema, patients with extensive thrombosis of the SVC, and in rare patients afflicted with severe venous hypertension and in whom a tissue diagnosis requires a mediastinal exploration. www.emory.edu /WHSCL/grady/amreport/litsrch02/s030122a.html   (2665 words)

AllRefer Health - SVC Obstruction (Superior Vena Cava Obstruction, Superior Vena Cava Syndrome) SVC obstruction is a narrowing or obstruction of the superior vena cava -- the major vein draining the upper body. Superior vena cava (SVC) obstruction is a relatively rare condition.

Superior vena cava syndrome Ahmann FR: A reassessment of the clinical implications of the superior vena caval syndrome. The treatment of superior vena cava syndrome (SVCS) depends on the etiology of the obstruction, the severity of the symptoms, the prognosis of the patient, and patient preferences and goals for therapy. SVCS is rare in children and appears at presentation in 12% of pediatric patients with malignant mediastinal tumors.[3,4] The etiology, diagnosis, and treatment of SVCS in children differs from that in adults. imsdd.meb.uni-bonn.de /cancernet/304708.html   (3115 words)

Superior Vena Cava Syndrome:   (Site not responding. Last check: 2007-11-07) Superior vena cava syndrome (SVCS) is an array of symptoms caused by the impairment of blood flow through the superior vena cava (SVC) to the right atrium. A nonmalignant cause of SVCS in cancer patients is thrombosis that is associated with intracaval catheters or pacemaker wires.

National Cancer Institute - Cardiopulmonary Syndromes Superior vena cava syndrome (SVCS) is the group of symptoms that occur when this vein is partially blocked. If the blockage occurs below where the superior vena cava and inferior vena cava meet, the blood must be returned to the heart by the veins in the upper abdomen and the inferior vena cava, which require higher pressure. If the blockage of the superior vena cava is caused by a tumor that is not sensitive to chemotherapy, radiation therapy may be given. www.cancer.gov /cancertopics/pdq/supportivecare/cardiopulmonary/Patient/page5   (1633 words)

Vena cava definition - Medical Dictionary definitions of popular medical terms Vena cava: The superior vena cava is the large vein which returns blood to the heart from the head, neck and both upper limbs. The superior vena cava syndrome is characterized by swelling of the face, neck and/or arms with visible widening (dilation) of the veins of the neck. Non-cancer causes of the superior vena cava syndrome include infections (such as tuberculosis, fungus, and syphilis), benign tumors (such as teratomas, thymoma, dermoid cyst), aortic aneurysm, pericarditis, sarcoidosis, irradiation treatment to the chest, air in the chest (pneumothorax), and complication of central line catheters and congenital heart surgery. www.medterms.com /script/main/art.asp?articlekey=5974   (617 words)

Superior Vena Cava Syndrome The SVC is formed by the junction of the left and right brachiocephalic veins in the mid-third of the mediastinum. In the absence of tracheal obstruction, SVCS is unlikely to be a life- threatening oncologic emergency and treatment prior to definitive diagnosis is not justified. SVCS does not appear to be an independent prognostic factor, and its presence should not be used to change the treatment approach. www.medhelp.org /lib/cancernet/304708.htm   (2575 words)

eMedicine - Superior Vena Cava Syndrome : Article by Andre M Kallab, MD Nonmalignant conditions causing SVCS include mediastinal fibrosis; vascular diseases such as aortic aneurysm, vasculitis, and arterial-venous fistulas; infections such as histoplasmosis, tuberculosis, syphilis, and actinomycosis; benign mediastinal tumors such as teratoma, cystic hygroma, thymoma, and dermoid cyst; cardiac causes, such as pericarditis and atrial myxoma; and thrombosis related to the presence of central vein catheters. Correction of SVCS was obtained in 9 (56%) of 16 patients treated with radiation therapy alone, in 23 (100%) of 23 given chemotherapy, and in 5 (83%) of 6 who received combined therapy. SVC stenting may provide relief of severe symptoms for patients while the histological diagnosis of the malignancy causing the obstruction is being actively pursued. www.emedicine.com /med/topic2208.htm   (3283 words)

Nonmalignant superior vena cava syndrome: Pathophysiology and management SVC syndrome is most frequently associated with malignancy (Table III) leading to compression and/or infiltration of the vena cava by tumor [[1]].

Superior Vena Cava Syndrome [1] A nonmalignant cause of SVCS in cancer patients is thrombosis that is associated with intracaval catheters or pacemaker wires. Surgical bypass of an obstructed SVC is more appropriate for patients with a benign obstruction than with a malignant obstruction, [17] although surgical bypass has also been used for patients with malignant obstructions. While the most frequent cause of SVCS in adults is bronchogenic carcinoma, [5] in children the most frequent malignant cause of the syndrome is non-Hodgkin’s lymphoma. www.meb.uni-bonn.de /cancer.gov/CDR0000062749.html   (3287 words)

Superior Vena Cava   (Site not responding. Last check: 2007-11-07) The vena cava is a large vein that runs along the right side of the body. It originates as the superior bulb of the jugular fossa, descends close to the internal and common carotid arteries, joins the subclavian vein to form the brachiocephalic vein. It is a single vein in 80% of individuals, and passes from the hilus of kidney behind the splenic vein and the body of the pancreas and then crosses in front of the aorta, posterior to the proximal superior mesenteric artery. www.meddean.luc.edu /lumen/MedEd/Radio/curriculum/Vascular/Veins.htm   (2488 words)
