Stenting o oko o te ngakau

Hoki te maimoatanga o te mate ngakau coronary, e hāngai ana nei i runga i te whāiti o te iatuku pūngākau (whangaia ratou te myocardium), i roto i te 1977 pūangi angioplasty o enei oko i whakamana mo te wa tuatahi. I roto i te nuinga o te wā, te take whāiti o te pera he putunga ngako ki runga ki te intima o oko, e arata'i ki te supply iti o te hāora ki te cardiomyocytes. Ka rite ki te putanga, te whakawhanake angina me te infarction myocardial.

hāngai poihau angioplasty technique te i runga i te meka e ki te ngakau i roto i te iatuku femoral pū tōngāmimi whangai kei i runga i tona mutunga te he soté (opupu ka rīhitia). I raro i X-ray whangai pū tōngāmimi mana te tika ki te pae o te whāiti, a ka rimurapa te poihau te - whakawhānui te uaua te. Ko te tikanga homai hua pai, engari maha matahoki (iatuku anō-whaiti, a tino).

I roto i te tikanga ki te whakawhānui i te whai huatanga o te opupu angioplasty, kua whakawhanakehia tākuta i te tikanga hou - cardiac stenting iaia. He stent Ko te mata tubular konganuku, he ahua o te anga kowiri tira. Roto te iatuku, fakalahi reira, e kore e tuku ki te spasm reira. whakamana Heart stenting iaia e rauemi rerekē e whai āhuatanga rerekē. O moni rahi he stents e kua pani ki te rauemi polymeric me matū rongoa (hei tauira, taero anticancer cytotoxic). Stenting o oko o te ngakau taua catheters taea whakaiti i te auau o te hanganga o whakatū papa atherosclerotic. Ko te mea utu te haamana'oraa e mā te whakamahi i enei stents te auau o whakaora o nga taiepa i roto o nga pera heke, i te mea he take o te tūpono Thrombosis.

Stenting o oko o te ngakau i roto i rite te ara ano rite opupu angioplasty. He he kotahi anake rerekētanga i te stent poihau kakahu, anga Uwhi. A, no te whakauru i te pū tōngāmimi ki te AVC takotoranga e nekehia, a ka faa'oru te poihau, te stent mo te faaafaro i te wahi i reira whāiti te uaua te. Ko te kupu, i whakakaha te taiepa iatuku whakawhānui te ka whakapūmautia i roto.

I te wā nei o stents ngakau - kē ki coronary täpiritanga uaua karo. Me kï hoki tetahi atu āhuatanga pai o stenting: te spasm o te iatuku pūngākau i roto i poihau angioplasty kia whakawhanake i tētahi infarction myocardial, e taea te karohia e te whakamahi i te stent. Stenting o pera o te ngakau inaianei - he tikanga o coronary täpiritanga uaua karo kē. I tua atu, ki te i roto i te akoranga o te mahi o te opupu angioplasty te AVC spazmiruyutsya, ko reira taea te whanaketanga o infarction myocardial, me stent i roto i tenei āhuatanga āwhina kia karo i tenei pōauautanga nui. A, no te coronary iatuku karo pokanga hawhe o nga tūroro whakawhanakehia stenosis o te whakanekeneke. Tona stenting Ko te rerekē pai ki toutou karo coronary. stents Cardiovascular hoki - he rerekē ki thrombolysis me te hangarau pai mo te maimoatanga o te infarction myocardial whakapeka tika i roto i nga haora tuatahi o tona whanaketanga.

Heoi, i reira he contraindications mo tenei tukanga. e kore e taea Stent whakanohonga ki whāiti E ruia ana o nga iatuku pūngākau. Ano, he tutukitanga tōnoa he iti (iti iho i te 2.8 mm) diameter o te uaua whāiti.

Hoki te ārai o ngā thrombotic whakamana tenei tukanga kei runga i te whakamārama o anticoagulants.

I muri i te mahi taua, e noho te manawanui i roto i te fare ma'i no te 5-7 ra a tawhio noa te karaka te tirotiro hauora. Postoperatively tonu antiplatelet me anticoagulation therapy.
