Maitiro eThrombosis, anosanganisira maitiro maviri:

1. Kunamatira uye kuungana kwemaplatelet muropa

Pakutanga kwe thrombosis, ma platelet anoramba achibuda kubva mu axial flow uye anonamatira pamusoro pe collagen fibers dzakaratidzwa pa intima yetsinga dzeropa dzakakuvara. Ma platelet anovhurwa ne collagen uye anoburitsa zvinhu zvakaita seADP, thromboxane A2, 5-AT uye platelet factor IV. , Zvinhu izvi zvine simba guru rekuunganidza ma platelet, zvekuti ma platelet ari muropa anoramba achiungana panzvimbo iyoyo kuti agadzire platelet yakaita se mound. , kutanga kwe venous thrombosis, musoro we thrombus.

Maplatelet anonamira pamusoro pema collagen fibers ari pedyo netsinga yeropa yakakuvara uye anobatidzwa kuti agadzire platelet yakaita sehillock. Hillock inowedzera zvishoma nezvishoma uye inosanganiswa nema leukocytes kuti igadzire thrombus chena. Ine ma leukocytes akawanda akabatana pamusoro payo. Kuyerera kweropa kunononoka zvishoma nezvishoma, coagulation system inobatidzwa, uye fibrin yakawanda inoumba network structure, iyo inobata masero matsvuku eropa akawanda nemasero machena eropa kuti igadzire thrombus yakasanganiswa.

2. Kuvhara ropa

Mushure mekunge thrombus chena yaumbwa, inobuda ichipinda muropa, zvichiita kuti ropa riri kuseri kwayo riderere uye riite serinotenderera, uye platelet mound itsva inoumbwa parinotenderera. Trabeculae, yakagadzirwa sekorari, ine ma leukocyte akawanda akabatana pamusoro payo.

Kufamba kweropa pakati petrabeculae kunodzikira zvishoma nezvishoma, system yekuonda inovhurwa, uye huwandu hwezvinhu zvinoonda munzvimbo uye zvinhu zvinoonda zvinowedzera zvishoma nezvishoma, zvichiita uye zvinobatana kuita chimiro chemesh pakati petrabeculae. Thrombus chena nechena, dzakasanganiswa dzakaita corrugated dzinoumba muviri wethrombus.

Thrombus yakasanganiswa yakawedzera zvishoma nezvishoma uye yakawedzera munzira yekuyerera kweropa, uye pakupedzisira yakavhara zvachose lumen yetsinga yeropa, zvichiita kuti kuyerera kweropa kumire.
