Stenting marinnada waxyaalaha qalbiga ku jira

Waayo, daaweynta cudurada wadnaha, kaas oo ku salaysan yahay cidhiidhi ee halbowleyaasha wadnaha (myocardium ay ku quudiyaan), 1977 baloonka ah weelashan waxaa la sameeyaa markii ugu horeysay. Xaaladaha intooda badan, cidhiidhi sabab halbowleyaasha waa baruur kayd ah ku intima, oo weelasha, taas oo horseedaysa in ay sahayda ah ku filnayn Ogsijiinta cardiomyocytes ah. Taa awgeed, angina horumarinta iyo Wadnaxanuun myocardial.

farsamada baloonka ku salaysan tahay xaqiiqada ah in wadnaha iyada oo halbowle ah bidig kateetarka quudin on kuwaas dhammaadkoodu waxa uu ku yaalaa cabbire ah (buufin baabi'say). Under X-ray tuubada gacanta si toos ah ku quudin jiray in ay goobta of cidhiidhi ah, ka dibna biibiilaha la badbadiyay - halbowlaha la balaariyay. Habka siinaysaa natiijooyin fiican, laakiin inta badan soo noqoshada (halbowlaha dib-u-Narrows, oo si weyn).

Si loo kordhiyo waxtarka baloonka, dhakhaatiirta ayaa soo saartay hab cusub - stenting vascular wadnaha. stent A waa mesh a embriyaha macdan ah, nooc ka mid ah qaab dhismeedka ahama. Inside halbowlaha ah, waxaa u fidiya, ma u ogolaanin in dabac. Heart stenting vascular waxaa la sameeyaa by qalab kala duwan oo ay leeyihiin guryaha kala duwan. Of danta ugu weyn waa stents in ay yihiin dahaarka leh kula qalabka polymeric iyo walxaha, daawooyinka (tus, daroogada anticancer cytotoxic). Stenting weelasha waxaa qalbiga ka soo tuubooyin sida uu yarayn karaa heerka of formation of dabar atherosclerotic. Laakiin waxaa haboon in la xasuusnaado in adigoo isticmaalaya stents, kuwaas oo heerka of bogsashada oo ka mid ah gudaha halbowleyaasha hoos u, taas oo ah arrin khatar thrombosis.

Stenting marinnada Qalbiga sax ah si la mid ah sida baloonka. Waxaa jira farqi hal kaliya stent biibiilaha gashan, qolof dahaarka leh. Marka bandhigid tuubo gelin ah halbowlaha wadnaha galkeeda laga saaro, ka dibna ka badbadinin biibiilaha, stent ee toosinta meeshii halbowle ah ayaa cidhiidhi ah. Sidaas darteed, derbiga halbowlaha balaariyay waxaa xoogaystay iyo gudaha ka xoojiyay.

At marxaladda la joogo oo ah stents wadnaha - beddeli kara in wadnaha Grafting hawlbowlaha dhiigga. Waa in la ogaadaa waji kale oo wanaagsan ee stenting: dabac ee halbowleyaasha wadnaha lagu jiro baloonka laga yaabaa in Wadnaxanuun a myocardial, taas oo in laga fogaadaa karaa iyadoo la isticmaalayo stent ah. Stenting ee halbowlayaasha qalbiga hadda - hab kale ee wadnaha Grafting hawlbowlaha dhiigga. Intaa waxaa dheer, haddii koorsada hawlgalka ee baloonka spazmiruyutsya halbowlaha wadnaha, waxaa suurto gal ah horumarinta Wadnaxanuun myocardial, iyo stent in xaaladda this ka caawisaa si looga fogaado dhibaato this halis ah. Marka coronary hawlbowlaha qeybtii qaliin bukaanka horumartay stenosis ee laga boodo ah. Uu stenting waa ka duwan oo fiican in la soo noqnoqda isku tallaalidda wadnaha. stents Sidoo kale wadnaha - duwan si thrombolysis iyo technology ugu fiican oo lagu daweeyo Wadnaxanuun myocardial ba'an si toos ah in ka saacadood ee ugu horeeya ee ay horumarka.

Si kastaba ha ahaatee, waxaa jira sababo nidaamka this. meelaynta stent suurtogal ma aha iyadoo cidhiidhi waajihi of halbowleyaasha wadnaha. Sidoo kale, caqabad aan laga gudbi karin waa dhexroor yar oo halbowle u cidhiidhi ah (in ka yar 2.8 mm).

Waayo, ka hortagga dhacdooyinka thrombotic habka this waxaa la sameeyaa ku saabsan asalka ah ee daawada xinjirowga.

howlgal noocan ah ka dib markii, bukaanka ayaa weli ku jira cisbitaalka for 5-7 maalmood ku dhawaad saacad kormeer caafimaad. Postoperatively sii antiplatelet iyo xinjirowga lidka ku ah daaweynta ay socoto.
