Embolism is the mobilization of a thrombus, a clot.

栓塞是栓、块的活动。

The most common pre-hepatic cause is portal vein obstruction, like when there's a thrombus occluding the portal vein and blocking blood flow.

的肝前型病因是门静脉阻塞，例如当有栓子阻塞门静脉流时。

Endothelial injury also leads to the formation of lots of tiny thrombi in the microvasculature, a process that uses up massive amounts of platelets.

皮损伤还导致微管形成大量微小栓，这一过程将消耗大量小。

Long-term treatment to prevent future thrombi from forming can include anticoagulant medications like warfarin or heparin, which inhibit the clotting cascade and prevent clot formation.

预防DVT的长期疗法包括华法林、肝素等抗凝药物的使用，可以阻断凝反应。

Finally, with protein C or S deficiency, there can be warfarin induced skin necrosis, which means tiny thrombi can form in the blood vessels of the skin, causing skin necrosis.

此外，患者身上还可能出现华法林导致的皮肤坏死，也就是说在皮肤管中形成小栓，导致皮肤坏死。
