Superior vena cava syndrome (SVCS), is a group of symptoms caused by obstruction of the superior vena cava ("SVC"), a short, wide vessel carrying circulating blood into the heart. The majority of cases are caused by malignant tumors within the mediastinum , most commonly lung cancer and non-Hodgkin's lymphoma , directly compressing or invading ...
A positive Pemberton's sign is indicative of superior vena cava syndrome (SVC), commonly the result of a mass in the mediastinum.Although the sign is most commonly described in patients with substernal goiters where the goiter "corks off" the thoracic inlet, [4] the maneuver is potentially useful in any patient with adenopathy, tumor, or fibrosis involving the mediastinum.
Superior vena cava obstruction refers to a partial or complete obstruction of the superior vena cava, typically in the context of cancer such as a cancer of the lung, metastatic cancer, or lymphoma. Obstruction can lead to enlarged veins in the head and neck, and may also cause breathlessness, cough, chest pain, and difficulty swallowing.
Usually, treatment involves surgical intervention in order to repair the persistent left superior vena cava (PLSVC) from draining into the left atrium. [1] Several surgical options can be used based on the individual. The main goal of these surgical interventions is to re-establish intracardiac flow of blood through the heart. [2]
Problems with the innominate vein and superior vena cava have also been reported to contribute to CCSVI. [27] A vascular component in MS had been cited previously. [28] [29] Several characteristics of venous diseases make it difficult to include MS in this group. [14] In its current form, CCSVI cannot explain some of the epidemiological ...
Oncological emergencies are a group of conditions that occur as a direct or indirect result of cancer or its treatment that are potentially life-threatening [1] These include: Hypercalcaemia; Neutropaenic sepsis; Tumour lysis syndrome; Leukostasis; Raised intracranial pressure; Spinal cord compression; Cauda equina syndrome; Superior vena cava ...
Non-developmental syndromes also directly or indirectly affect the Great Cerebral Vein of Galen, although they are extremely rare. These include superior vena cava syndrome (SVCS), and thrombosis of the lateral sinus, superior sagittal sinus, internal jugular vein, or of the Great Cerebral Vein of Galen itself. [citation needed]
The left superior vena cava is not shown in this image. In anatomy , a persistent left superior vena cava is the most common variation of the thoracic venous system . [ 1 ] [ 2 ] It is present in between 0.3% and 0.5% of the population, [ 3 ] [ 4 ] [ 5 ] and is an embryologic remnant that results from a failure to involute .
