血栓为心脏和血管内产生凝固的肿块。血栓引起血管腔的狭窄和阻塞,例如心、肺、脑等缺血性病变在血栓产生梗塞时,引起这些脏器的功能障碍。血栓引起的栓塞,动静脉都可产生。动脉血栓的好发部位主要在大腿、腋窝,上腕动脉等形成血管鞘处。动脉血栓多数情况为心脏疾患,如二尖瓣病、心肌梗死等引起心内血栓为多。特别在腹部大动脉分枝处所谓鞍状血栓易引起栓塞。静脉血栓在四肢静脉比动脉发生率要高。血栓的诊断方法之一为不验血的核医学检查。曾用~(125)I、~(131)I-纤维蛋白原开始查出过深部静脉血栓。特别是近年来用~(111)In-羟基亚胺(Oxine)标记
Thrombus is a solidified mass in the heart and blood vessels. Thrombus causes stenosis and occlusion of the lumen of the blood vessels, such as heart, lung, brain and other ischemic lesions caused by the thrombus infarction, causing dysfunction of these organs. Thrombosis caused by embolism, arteries and veins can be produced. The main site of arterial thrombosis in the thigh, armpit, upper carpal artery and other forms of vascular sheath. Artery thrombosis in most cases of heart disease, such as mitral valve disease, myocardial infarction caused by intracardiac thrombosis and more. Especially in the abdominal aorta branches so-called saddle thrombosis easily lead to embolism. Venous thrombosis occurs more frequently in the extremities than in the arteries. One of the diagnostic methods of thrombus is nuclear medicine examination without blood test. Have used ~ (125) I, ~ (131) I-fibrinogen began to detect deep venous thrombosis. In particular, it has been labeled with ~ (111) In-hydroxyimine in recent years
