Stenting arịa nke obi

Maka ọgwụgwọ nke ịrịa ọrịa obi, nke dabeere na ibelata nke akwara akwara (ha na-eri nri ndị myocardium), na 1977 balloon angioplasty ndị a arịa e rụrụ maka oge mbụ. N'ọnọdụ ka ukwuu, ihe na-akpata ibelata nke akwara bụ abụba ego na intima nke arịa, nke na-eduga onye ezughi oke ọkọnọ nke oxygen na cardiomyocytes. N'ihi ya, na-emepe emepe rịaworo na myocardial infarction.

Balloon angioplasty Usoro dabeere na eziokwu na obi site na femoral akwara nri catheter na onye ọgwụgwụ na-emi odude a cuff (balloon deflated). N'okpuru X-ray akara catheter nri ozugbo na saịtị nke ibelata, mgbe ahụ, balloon na-inflated - na akwara na-gbasaa. The usoro-enye nti utịp, ma ọtụtụ mgbe nlọghachi azụ (akwara re-asụchikwa, na budata).

Iji ịgbatị irè nke balloon angioplasty, ndị dọkịta mepụtara a ọhụrụ usoro - gbasara obi vaskụla stenting. A stent bụ a dara tubular ntupu, a ụdị igwe anaghị agba ígwè eku. Inside na akwara, ọ kọwakwuru, ọ bụghị ikwe ka ọ na spasm. Heart vaskụla stenting a rụrụ site dị iche iche ihe nke nwere dị iche iche Njirimara. Of kasị ukwuu mmasị bụ stents na-ntekwasa na polymeric ihe na ọgwụ bekee (e.g., cytotoxic anticancer ọgwụ ọjọọ). Stenting arịa nke obi dị otú ahụ catheters ike belata ọnụego nke guzobere atherosclerotic mbadamba nkume ndị e. Ma ọ bụ uru na-echeta na site na iji ndị stents ọnụego nke na-agwọ ọrịa nke n'ime mgbidi nke akwara mbelata, nke bụ a na-akpata nke thrombosis ize ndụ.

Stenting arịa nke obi kpọmkwem n'otu ụzọ ahụ balloon angioplasty. E nwere nanị otu ihe dị iche na balloon stent uwe, ntekwasa shei. Mgbe ewebata a catheter n'ime ndị akwara akwara n'ọbọ-ewepụ, na mgbe ahụ ibugo onu na balloon, na stent maka idozi ebe ihe akwara na-narrowed. N'ihi ya, na-amụba akwara mgbidi na-esikwu ike na mesikwuru site n'ime.

N'oge ugbu ogbo nke obi stents - uzo ozo ka akwara akwara uzo grafting. Ọ ga-kwuru ọzọ mma akụkụ nke stenting: na spasm nke akwara akwara n'oge balloon angioplasty nwere ike ịzụlite a myocardial infarction, nke nwere ike izere site na iji a stent. Stenting nke akwara nke obi ugbu a - ka onye ọzọ usoro akwara akwara uzo grafting. Ke adianade do, ma ọ bụrụ na na N'ezie nke ọrụ nke balloon angioplasty akwara akwara spazmiruyutsya, ọ bụ omume na mmepe nke myocardial infarction, na stent na ọnọdụ a na-enyere aka igbochi nke a dị oké njọ sikwuoro. Mgbe akwara akwara wasịrị ọkara nke ndị ọrịa mepụtara stenosis nke shunt. Ya stenting bụ a ọma ọzọ ka ugboro ugboro akwara uzo. Ọzọkwa obi stents - onye ọzọ na thrombolysis na mma technology maka ọgwụgwọ nke nnukwu myocardial infarction nnennen nnennen ke akpa awa nke ya mmepe.

Otú ọ dị, e nwere contraindications maka a na usoro. Stent pụrụ isi chọta bụ ekwe omume na asị ibe ibelata nke akwara akwara. Ọzọkwa, onye na-agaghị emerili nsogbu bụ obere (ihe na-erughị 2.8 mm) dayameta nke narrowed akwara.

N'ihi mgbochi nke thrombotic ihe a usoro a rụrụ na ndabere nke anticoagulants.

Mgbe ihe dị otú ahụ ime ihe ahụ, onye ọrịa na-anọgide na ụlọ ọgwụ maka 5-7 ụbọchị gburugburu elekere nlekọta nke ndị ọrụ. Postoperatively aga n'ihu antiplatelet na anticoagulation ọgwụ.
