RESUMEN
Superior Vena Cava Syndrome is the clinical manifestation of the Superior Vena Cava obstruction, with severe reduction in venous return from the head, neck and upper extremities. More than 80% cases of SVCS is nearly attributable to advanced malignancy, most commonly lung cancer. SVC syndrome is characterized by congestion and swelling of the face and upper thorax, with distended superficial chest veins. The most severe complications of SVC syndrome include Glottic edema and venous thrombosis in the central nervous system. We represent a case SVC syndrome due to Small Cell Cancer of the lung.
RESUMEN
Subclavian steal syndrome is a relatively rare condition that results from occlusion of the subclavian artery proximal to the origin of the vertebral artery. This causes a reversal in the direction of the blood flow in the vertebral artery, leading to symptoms of vertebrobasilar insufficiency. In this article, we report a case of subclavian steal syndrome in a 55 year old male, who presented with giddiness, and variation in blood pressures in both upper limbs, was investigated with doppler and MR angiography. This article emphasises physical examination with discrepancy in pulse and blood pressure should bring attention to diagnosis of this syndrome.
