Isiyobisi esinyusa iziyobisi sisixhobo esifana nentwasahlobo, esigutyungelwe ngamachiza athomalalisa ukuvuvukala kunye nokuchaphazeleka komzimba osebenza ukuvulela imithambo yentliziyo, ingqondo okanye nezintso.

Ziyahluka kwizinto eziqhelekileyo ekubeni zinamayeza kwizakhiwo zazo. La mayeza akhutshwa kwiinyanga ezili-12 zokuqala zokufakwa, ukuze kuncitshiswe ithuba lokuvaleka kwenqanawa kwakhona. Kwizinto eziqhelekileyo, ezibonisa kuphela ubume bentsimbi, ngaphandle kwamayeza, kukho umngcipheko omkhulu wokuba, kwiinyanga zokuqala ezili-12 zokumiliselwa, inqanawa iya kuvalwa kwakhona.

I-Angioplasty ene-stent yokunyanga iziyobisi

Kwi-angioplasty ene-stent e-drug-eluting stent, i-stent ifakwa kwi-artery evaliweyo ngokusebenzisa i-catheter kwaye isebenza njengesakhelo, esityhala iiplati ezinamafutha eziphazamisa umthambo, ukukhusela ukuhamba kwegazi, kwaye "kubambe" iindonga umthambo ukuze uhlale uvulekile, uvumela ukuhamba kwegazi okungcono.Ezi stents zikwasebenza ngokukhulula kancinci amayeza e-immunosuppressive anciphisa ithuba lokuvalwa kwenqanawa entsha.

Iimpawu zokubonisa iziyobisi

Indawo yokunyusa iziyobisi ibonakalisiwe ekucoceni imithambo, ukuba nje ayisiyonto inzima okanye isondele kakhulu kwindawo yokubopha, apho i-artery e-1 yahlulwe yaya ku-2.

Ngenxa yeendleko eziphezulu, ukusetyenziswa kweziyobisi kugcinelwa iimeko zezigulana ezisemngciphekweni omkhulu wokuvalwa kwenqanawa entsha, enjengezigulana ezinesifo seswekile, izilonda ezibanzi, isidingo sokubeka isenti ezininzi, phakathi kwezinye.

Ixabiso lentlawulo yeziyobisi

Ixabiso le-stent eluting drug limalunga ne-12 lamawaka reais, kodwa kwezinye iidolophu eBrazil, inokuhlawulwa yi-SUS.

Izibonelelo zestent-eluting stent

Enye yeenzuzo zokuthambisa iziyobisi ngokunxulumene nokusetyenziswa kwesitenti sendabuko (esenziwe ngentsimbi) kukukhutshwa kwamayeza ukuze kuncitshiswe ithuba le-stenosis entsha okanye ukuvalwa kwenqanawa.
