Esila Angioplasty
Iji dọkịta ọrịa, dọkịta na-eji catheter (nke dị ogologo, nke dị nfe, nke na-agbanwe tube) nke nwere balloon nke a na-emetụta na ya. A na-agafe efere na-agafe akara ngosi nke na-emepụta mkpọchi ahụ, a na-agbakwa balloon n'okpuru nrụgide. Mgbasawanye nke balloon na-eme ka ihe ngosi ahụ dị na mgbidi nke ikuku. Mgbe balloon na-agbagha ma wepụ ya, ihe ncheta ahụ na-anọgide na ọ dịkarịa ala na-etinye ya n'ahụ, ya mere, a na-ebelata mkpọchi ahụ.
Ọ bụ ezie na a na-emebu angioplasty dịka usoro nkwụsị, taa, a na-etinyekwa stent mgbe ọ bụla a na-eme angioplasty na akwara akwara. Ihe na-esi ike bụ "scaffold" nke na-enye aka na-akwado mgbidi nke ikuku na saịtị nke angioplasty, iji mee ka ihe nrụgide ahụ dị. A na-etinye ụdọ na-ada mbà na balloon tupu etinye ya.
Mgbe ahụ, mgbe a na-ebugharị balloon, a na-etinye ihe ncheta ahụ ma na-agbasapụ aka n'otu oge ahụ. Mgbe a na-agbazi balloon ma wepụ ya, a na-ahapụ ọnyá ahụ n'ebe ahụ, na-enyere aka idebe ihe mbadamba nkume ahụ ma mechie ya.
Mgbe Ọ Na-enye Aka
Angioplasty dị irè iji belata ihe mgbaàmà nke angina .
Ya mere, isi ihe mere eji eme ihe na-akpata ọrịa strok bụ ịgwọ angina nke nọgidere na-emegidesi ike n'agbanyeghị mbọ ndị na-agwọ ọrịa. Ọ bụ ezie na ọ nwere ike iyi ihe ijuanya na ọtụtụ ndị, angioplasty (ọbụlagodi mgbe a na-agbanye stent) adịghị egosi na ọ dị irè karịa ọgwụgwọ ahụ iji belata ihe ize ndụ ọzọ nke ịmịnye ụbụrụ myocardial (mgbu obi), ma ọ bụ iji meziwanye ndụ. Ya mere, isi ihe mere eji eme ka angioplasty bụ ịkwado angina ahụ nọgidere na-agbaso n'agbanyeghị mbọ iji na-emeso ya ọrịa.
Ihe nke abuo a na-ejikarị ọrịa angiolasty (na ntigide) na-agwọ ọrịa ọrịa akwara ọbara na-arịa ọrịa ndị na- arịa ọrịa coronary (ACS). Na ACS, nnukwu mkpuchi nke akwara coronary emeela n'ihi na a na-agbaji akara ma na-akpụ akpụ n'ime akwara. Mgbe ACS nọ na-eme, ọnyá obi ga-abụrịrị ọ gwụla ma e mepere ikuku.

Akwara akwara na-eme ka ọ bụrụ ọ bụghị naanị akwara nke a na-ejikarị na-agwọ ọrịa angioplasty iji na-emeso ihe atherosclerotic obstructive. A na-etinyekwa angioplasty n'ahụ akwara carotid (nke na-enye ụbụrụ), akwara akwara (nke na-enye akụrụ) na akwara ụkwụ.
Nsogbu
Ihe mgbagwoju anya kachasị na-eso angioplasty naanị bụ restenosis - nhazi nke ọhụrụ blockage na saịtị nke akara mpempe akwụkwọ. Restenosis bụ usoro dị nwayọọ na-eme ka ọganihu ọhụrụ nke anụ ahụ-ma eleghị anya na-emeghachi omume maka nsogbu ahụ nke angioplasty na-emepụta na na gburugburu arịa ahụ. A na-ebelata ụba nke restenosis site na iji stents, karịsịa ọgwụ na-asọpụta stents (DES), nke na-ekpuchi na ọgwụ na-egbochi uto nke anụ ahụ, si otú ahụ na-ebelata restenosis.
Tupu oge nke stents, oge fọdụrụ restenosis mere na ihe fọrọ nke nta ka 30% nke ndị ọrịa nwere angioplasty naanị.
Ojiji nke ụbụrụ ndị na-adịghị ahụ anya na-ebelata ihe ize ndụ a na ihe na-erughị 15%, na stent-dropping stents belata ya na-erughị 10%.
Nsogbu na-adịkarịghị, ma ihe na-agbawa agbawa, bụ thrombosis (ịkpụ ọbara) na saịtị nke angioplasty / stenting. Egwu thrombosis bụ ihe na-eme na mberede na mgbe mgbe, nke na-emepụta nkwụsịtụ zuru oke na zuru oke nke ikuku na-emetụta. A na-ahụkarị ngwromosis oge na-adịghị anya mgbe usoro angioplasty (nke bụ, n'ime ụbọchị ruo izu).
