ʻO nā kumu o ka thrombosis penei:

1. Pili paha ia i ka endothelial eha, a ua hanaia ka thrombus ma ka endothelium vascular.ʻO ka pinepine ma muli o nā kumu like ʻole o ka endothelium, e like me ke kemika a i ʻole ka lāʻau a i ʻole endotoxin, a i ʻole ka ʻeha endothelial i hana ʻia e ka atheromatous plaque, etc., endothelial thrombus forms ma hope o ka ʻeha;

2. No ka laʻana, ʻo ka coagulation o ke koko, ka piʻi ʻana o ka hana platelet, a i ʻole ke ʻano like ʻole o ka mīkini coagulation koko hiki ke alakaʻi i ke kūkulu ʻana i ka thrombus;

3. Hoʻolohi ka kahe o ke koko a i ʻole ka emi ʻana o ke koko, a piʻi ka nui o ke koko, hiki ke alakaʻi i ke kūkulu ʻana i ka thrombus, no laila he nui nā kumu no ka hoʻokumu ʻana o ka thrombus;

4. Ma waho aʻe o nā kumu i ʻōlelo ʻia ma luna nei, ʻo nā kumu o ka thrombus pū kekahi me ka hoʻonui ʻana i ka hana o ka ʻōnaehana fibrinolytic.Eia kekahi, aia ka piʻi ʻana o ka nui o nā platelets, hiki ke alakaʻi i kahi maʻi thrombotic, no laila he nui nā kumu.
