Kukhulunywa ngakho ekuphathweni kwesigaba sokuhlinzwa ukuze kuvinjelwe i-thrombosis: Ukuvimbela i-thrombosis ejulile yemithambo yegazi kumele kunakwe. Ingozi yokwakheka kwe-thrombosis ejulile yemithambo yegazi yozalo lukamama ngemva kwesigaba sokuhlinzwa iyanconywa. Ngakho-ke, kunconywa izinyathelo zokuvimbela. Ukukhuthaza ukuvuka ngokushesha ngangokunokwenzeka embhedeni, ngokwezinto eziyingozi kakhulu zokwakheka kwe-thrombosis, ukukhetha komuntu ngamunye ukugqoka amasokisi anwebekayo, izinhlelo zokuvimbela amadivayisi okuphefumula ngezikhathi ezithile, ukugcwalisa amanzi, kanye nokufakwa kwe-heparin yama-molecule aphansi ngaphansi kwesikhumba.
