Mapangidwe a thrombus amakhudzana ndi kuvulala kwa vascular endothelial, hypercoagulability ya magazi, komanso kuchepa kwa magazi.Choncho, anthu omwe ali ndi zifukwa zitatu izi amatha kukhala ndi thrombus.

1. Anthu omwe ali ndi vuto la mitsempha ya endothelial, monga omwe adutsa mitsempha ya mitsempha, catheterization ya venous, etc., chifukwa cha kuwonongeka kwa mitsempha ya endothelium, ulusi wa collagen womwe umawonekera pansi pa endothelium ukhoza kuyambitsa mapulateleti ndi coagulation factor, zomwe zingayambitse endogenous coagulation.Dongosolo limayambitsa thrombosis.

2. Anthu omwe magazi awo ali mu hypercoagulable state, monga odwala zotupa zowopsa, systemic lupus erythematosus, kuvulala koopsa kapena opaleshoni yaikulu, amakhala ndi zinthu zambiri zomwe zimagawanika m'magazi awo ndipo amatha kugawanika kusiyana ndi magazi achibadwa, choncho amakhala otheka kwambiri. kupanga thrombosis.Chitsanzo china ndi anthu omwe amatenga njira zolerera, estrogen, progesterone ndi mankhwala ena kwa nthawi yaitali, ntchito yawo ya coagulation ya magazi idzakhudzidwanso, ndipo zimakhala zosavuta kupanga magazi.

3. Anthu omwe magazi awo amatsika pang'onopang'ono, monga omwe amakhala nthawi yayitali kusewera mahjong, kuwonera TV, kuphunzira, kuphunzira kalasi yachuma, kapena kukhala pabedi kwa nthawi yayitali, kusachita masewera olimbitsa thupi kungayambitse magazi m`mbuyo kapena stagnate Mapangidwe vortices kuwononga yachibadwa magazi boma, amene adzawonjezera mwayi wa kupatsidwa zinthu za m`mwazi, maselo endothelial ndi coagulation zinthu kukhudzana, ndipo n`zosavuta kupanga thrombus.
