血管的通畅取决于至少六种极为复杂且密切联系的系统之间的精细平衡,包括内皮、内皮下结构、血小板、凝血系统和纤维蛋白溶解系统以及这二系统的抑制物质、循环中血流的特性等。这些止血系统之间的细微平衡变化,即能导致严重的出血或血栓栓塞。本文重点讨论血栓形成及其处理。 Vascular patency depends on a fine balance between at least six extremely complex and closely related systems including the endothelium, the subendothelium, platelets, the coagulation system, and the fibrinolytic system, as well as the inhibitory substances of these two systems, circulating blood flow Characteristics and so on. The slight balance between these hemostatic systems can lead to severe bleeding or thromboembolism. This article focuses on thrombosis and its management.
