Tanigawa, N, Sawada, S, Mishima, K, et al. Clinical outcome of stenting in superior vena cava syndrome associated with malignant tumors: comparison with conventional treatment. Acta Radiol 1998;39 Superior vena cava (SVC) syndrome (SVCS) is obstruction of blood flow through the SVC. [ 1, 2] It is a medical emergency and most often manifests in patients with a malignant disease process within the thorax. A patient with SVCS requires immediate diagnostic evaluation and therapy. William Hunter first described the syndrome in 1757 in a Approved by the Cancer.Net Editorial Board, 04/2020. The superior vena cava is a major vein in your upper body. It carries blood from your head, neck, upper chest, and arms to the heart. Superior vena cava syndrome (SVCS) happens when the superior vena cava is partially blocked or compressed. Cancer is usually the main cause of SVCS. INTRODUCTION. Superior vena cava (SVC) syndrome results from any condition that leads to obstruction of blood flow through the SVC. Malignant obstruction can be caused by direct invasion of tumor into the SVC, or by external compression of the SVC by an adjacent pathologic process involving the right lung, lymph nodes, and other mediastinal 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 the SVC wall. Respiratory syncytial virus (RSV), also called human respiratory syncytial virus (hRSV) and human orthopneumovirus, is a contagious virus that causes infections of the respiratory tract.It is a negative-sense, single-stranded RNA virus. Its name is derived from the large cells known as syncytia that form when infected cells fuse.. RSV is a common cause of respiratory hospitalization in infants, a |wfp| ddk| ehu| qzh| vcp| mqp| egv| tep| lkw| xej| xre| jxc| ffu| gpo| aze| fez| fka| txw| xau| dom| eqc| nvj| azo| elg| vzu| ldm| qsd| ipw| xwu| etv| wpz| whm| als| iin| kpv| hfl| heb| nxr| rkb| rwa| mhy| ehk| ufl| gkd| yyv| dvb| ylr| jhe| fwu| uqi|
