Stenting likepe ba pelo

Bakeng sa ho phekoloa lefu gogoga pelo, e leng e thehiloe narrowing tsa methapo gogoga (ba fepa myocardium), ka 1977 balune angioplasty ya lijana tsena ile a etsa ka lekhetlo la pele. Maemong a mangata, sesosa narrowing ya methapo ya di mafura mobung ka intima likepe, e leng e isa e phepelo lekaneng ea oksijene ho cardiomyocytes ena. Ka lebaka leo, tsoelang pele angina le myocardial infarction.

Lewa Balloon angioplasty e thehiloe e le hantle hore ho pelo ea ka e femoral mothapo fepa catheter eo qetellong e teng le cuff (balune deflated). Tlas'a X-ray taolo catheter feptjoang ka ho toba sebakeng sa narrowing, ebe balune e moya na - mothapo e atolositsoeng. mokhoa ea fana ka litholoana tse molemo, empa hangata khutlela mokhoeng (mothapo botjha sesefatsa, 'me haholo).

E le hore ho eketsa ho atleha ha balune angioplasty, lingaka li qapa mokhoa ntjha - cardiac vascular stenting. stent A ke metallic tubular letlooeng, le oa mofuta ofe foreime celik. Ka hare mothapo, ho atolosa, se ke ra lumella ho spasm. Pelo ea vascular stenting o etsoa ke thepa e fapaneng eo na le thepa e fapaneng. Thahasella khōlō ka ho fetisisa ke stents tse a tlotsitsoeng ka thepa e polymeric le dintho meriana (mohlala, cytotoxic anticancer lithethefatsi). Stenting likepe ba pelo catheters joalo ka fokotsa tekanyo ea sebopeho sa plaques atherosclerotic. Empa ke habohlokoa ho hopola hore ka ho sebelisa stents tsena ka tekanyo ea ho folisa ha marako le ka hare la methapo ea decreases, eo ke le palokatiso ya thrombosis kotsi.

Stenting likepe ba pelo ka hantle ka tsela e tšoanang ka balune angioplasty. Ho na le phapang e 'ngoe feela ka balune stent apara, lera khetla. Ha u kenyelletsa ya catheter ka ho gogoga mothapo selateng sa e tlosoa, 'me joale ya moya e tlala ka balune, ho stent bakeng ogee sebakeng seo mothapo e e narrowed. Kahoo, e atolositsoeng mothapo leboteng ea matlafala le ho matlafatsoa ho tswa ka hare.

Ka ho ba sethaleng hona joale ea stents pelo - mekhoa e meng ea ho gogoga mothapo kgaoleditse grafting. Re lokela ho hlokomela ntlha e 'ngoe e ntle ea stenting: ho spasm ea methapo gogoga nakong balune angioplasty ka' na e-ba le infarction myocardial, e ka qojoa ka ho sebelisa stent. Stenting tsa methapo ea pelo hona joale - le mokhoa meng ea gogoga mothapo kgaoleditse grafting. Ho phaella moo, ha ho tsela ea ho sebetsa ha balune angioplasty gogoga mothapo spazmiruyutsya, ho ka etsahala ho hōla ha infarction myocardial, le stent boemong boo thusa ho qoba complication ena e tebileng. Ha gogoga mothapo buuoe halofo ea bakuli ntshetswa stenosis tsa shunt ena. stenting hae ke e ntle seng ho fapana pheta gogoga kgaoleditse. stents hape pelo - e seng ho fapana thrombolysis le theknoloji ho fetisisa bakeng sa kalafo ya a hlobaetsang myocardial infarction kotloloho ka lihora pele ho hōla eona.

Leha ho le joalo, ho na le contraindications ho Tsamaiso ena. Stent placement ke ke ha khoneha le diffuse narrowing tsa methapo gogoga. Hape, e le tšitiso hlōloa ke nyenyane (ka tlase ho 2,8 limilimithara) bophara ba mothapo ho narrowed.

Bakeng sa thibelo ea liketsahalo thrombotic Tsamaiso ena e etsoa ka semelo sa anticoagulants.

Ka mor'a opereishene e joalo, mokuli o hlola ka ho ka sepetlele bakeng sa matsatsi a 5-7 pota oache tlhokomelo ea meriana. Postoperatively tsoela pele antiplatelet le anticoagulation phekolo.
