Kusangana kweplatelets panguva yekuzvimba ndeimwe yezvinonyanya kukosha zviratidzo, kuderedzwa kunogona kubatsira pakubuda ropa. Kubatana mumishonga kunoreva kukwanisa kweplatelet kuti ubatane, kureva, kuisa maplatelet eropa.
Izvi zvinotevera. Kana masvingo emidziyo yacho akaparara, ropa rinotanga kubuda kubva kwavari kuti ridzivirire migumisiro, muviri unotumira anera kumasero. Somugumisiro, panzvimbo yekuparara, maplatelet anoonekwa uye, achibatana pamwe chete, kuvhara zvipembenene mumudziyo.
Kuti uone chinangwa ichi, coagulogram inoitwa-kuongorora ropa nekushandisa nzira ye laboratory uchishandisa inducers-zvimwe zvinhu zvinokuvadza aggregation. Chimiro chekubatana kweplatelets panguva yekuzvitakura kana kuwirirana nemumwe wezvinhu izvi 30-60%.
Hypoaggregation yeplatelet panguva yekuzvitakura
Kuderedza kweplatelet aggregation panguva yekuzvitakura kunogona kuitika nekuda kwekuparadzwa kwakawanda kana kushandiswa kweplatelet yeropa. Zvinokonzera izvi zvinogona kugara zvichibuda ropa, kutyora muviri wemuviri, kana kudya kwakashata kwemukadzi ane pamuviri. Hypoaggregation yamaplatelets panguva yekuzvitakura inoratidzwa nezviratidzo zvakadai sokupwanya uye kubuda ropa. Mumamiriro ezvinhu akadaro, mahwendefa eropa anobudiswa mune zvishoma, kana kuwana chimiro chisina kukodzera. Mukubereka mwana chiratidzo chakadai cheropa coagulability chinogona kutungamirira kubuda ropa kwakanyanya.
Hyperaggregation of platelets panguva yekuzvitakura
Kuwedzerwa kuduku kunofungidzirwa sechinhu chechisikigo panguva yekuita gumbo - izvi zvinosanganiswa ne utero-placental circulation. Hyperaggregation of platelets panguva yekudzivirira inogona kukanganisa kugadzirwa kwe thrombi. Chirwere, chirwere chinopisa kana chinopisa, chinogona kuendeswa ne antiphospholipid syndrome, iyo inowanzokonzera kukanganisa mumatangi ekutanga.
