Iimviwo ze-radiographic eziqhelekileyo azivumeli uviwo lweemitharizo, i- lymph nodes kunye nemithanjeni, kuba zinamakhono afanayo okuxhamla ngokubhekiselele kwimimandla ejikelezayo. Ukuqwalaselwa ngokucokisekileyo, inkqubo ekhethekileyo isetyenziselwa ukusetyenziswa kwee-agent ezichaseneyo-i-angiography yeempahla. Olu buchule lunikeza ukuxilongwa kwangaphambili kweemeko zokuqala zezifo zemithambo nemithambo.
Iyintoni i-engiography yeempahla zentamo, kwaye le nkqubo yenziwa njani?
Olu hlobo lwesifundo lenzelwe ukufumana izilonda ze-atherosclerotic zeetriyri ze-carotid. Zifakwe entanyeni, ngoko i-angiography iqhutyelwa kule ndawo.
Inkqubo:
- Unyango lwe-site ye-catheterization kunye ne-antiseptic kunye ne-anesthetic yendawo.
- Ukugqithwa kwesitya.
- Isingeniso sesingeniso (ityhubhu yeplastiki).
- Ukufakwa kweCatheter.
- Isingeniso sesisombululo se-radiopaque kwi-artery.
- Ucwaningo lwe-X-ray yesayithi esichazwe kwiprogram kunye neempahla ezihlolwayo.
- Ukukhutshwa kwecatheter kunye nokwazisa.
- Faka isicelo sokufaka ibhanti yokunyanzeliswa kwisayithi sokugqitywa komda.
Kufuneka ukuba uqaphele ukuba ukulandelelana kwezenzo ezichazwe ngasentla kufana nokufunda zonke iziko. Kuphela iindawo zokufakelwa kwecatheter zingahluka.
Iimpawu ze-angiography yeempahla zeentso
Kwiimeko ezininzi, ukuvavanya iinkqubo ezinkulu zee-vascular, i-X-ray efana neyoyiyo ifakwe kwi-aorta ye-femor (i-transfemoral). Kodwa ekufundeni kweentso, enye indlela yokungena isisombululo sinokwenzeka: ukuguqulela. Kuquka ukungeniswa kwenkathazo kwi-aorta esiswini.
Ngokufanayo, i-angiography yeempahla zesigumbi esisisu sisenziwa. Ukuqaliswa kwecatheter ngokugqithisileyo kuqinisekisa ukusabalalisa ngokukhawuleza kwesisombululo se-X-ray kwindawo yokufunda ngaphandle kwendlela yokuphambanisa.
Injani i-cardiovascular angiography?
Olu hlobo loviwo lwe-coronography (i-coronography), njengommiselo, lwenziwe nge-injection yezinto ezichaseneyo kwi-aorta yesifazane. Kwiimeko ezinqabileyo, inqanawa enkulu kwisandla sekhohlo ikhethiweyo.
I-Angiography ingenziwa kwakhona kuphando:
- ingqondo ;
- fundus;
- izitho;
- nayiphi na indawo yendlela yokugaya;
- izitho zentsimbi encinci.
