Stenting kweenqanawa zentliziyo

Kuba unyango lwesifo sentliziyo, olusekelwe phezu licuthe kwemithambo yenhliziyo (zondla myocardium), ngo-1977 ibhaloni angioplasty lwezo mpahla wenziwa okokuqala. Kwiimeko ezininzi, unobangela licuthe kwemithambo ezi iidipozithi manqatha phezu kwazo intima iimpahla, nto leyo ekhokelela ukuba unikezelo elingonelanga oxygen cardiomyocytes. Ngenxa yoko, angina ukuphuhlisa kunye iposi engabalulekanga.

Ibhaloni angioplasty ndlela isekelwe kwinto yokuba intliziyo nge kwemithambo femoral catheter adla abasiphelo sayifumana cuff (ibhaluni kumiyo). Phantsi X-ray ulawulo catheter sidla ngqo nesiza licuthe; kwandule ke ibhaluni ke olunyuswe - kwemithambo iyandiswa. Le ndlela inika iziphumo ezilungileyo, kodwa ndiphinde (Umthambo kwakhona uncipha-, kwaye kakhulu).

Ukuze ukwandisa impumelelo ibhaloni angioplasty, oogqirha baye basungula indlela entsha - kwentliziyo stenting nemithambo. A stent i tubular enemingxuma ebuntsimbi, uhlobo benqwanqwa steel stainless. Ngaphakathi kwemithambo, ayanda, angavumeli ukuba spasm. Heart stenting semithambo lwenziwa yi ngezinto ezahlukeneyo kulo iipropati ezahlukeneyo. Of umdla ezona stents ukuba isale izinto polymeric zingangeni amayeza (umz, iziyobisi anticancer cytotoxic). Stenting kweenqanawa zentliziyo enjalo catheters nga ukunciphisa izinga ukuyilwa umonakalo atherosclerotic. Kodwa ke kubalulekile ukukhumbula ukuba ngokusebenzisa ezi stents izinga yokuphilisa beendonga angaphakathi kwemithambo unciphisa, nto leyo ngumba umngcipheko thrombosis.

Stenting kweenqanawa wentliziyo kanye ngendlela efanayo ibhaloni angioplasty. Inye kuphela umahluko kwi stent ibhaluni enxibe, iqokobhe camera. Xa kuqaliswa catheter kungena kulo kwemithambo esingxotyeni isusiwe, uze zivuthelana ibhaluni, lo stent ngenxa nokolula indawo apho i umthambo na imithambo. Ngenxa yoko, udonga kwemithambo eyandisiweyo yomelezwa kwaye luqiniswe evela ngaphakathi.

Ngelo langoku ibakala stents intliziyo - ezinye coronary kwimithambo esa yokumilisela. Kufuneka kuqatshelwe enye inkalo esihle stenting: i spasm kwemithambo yenhliziyo ngexesha ibhaloni angioplasty basenokuba iposi engabalulekanga, leyo kuphetshwe ngokusebenzisa stent. Stenting ezincinane zentliziyo ngoku - enye indlela coronary kwimithambo esa yokumilisela. Ukongeza, ukuba ngethuba kukusebenza ibhaloni angioplasty kwemithambo spazmiruyutsya, kunokwenzeka uphuhliso iposi engabalulekanga, kunye stent kule meko inceda ukuthintela oku ingxaki kakhulu. Uqhaqho kwimithambo esa igazi isiqingatha izigulane xa kuphuhliswa stenosis le shunt. stenting yakhe okunye okuhle okunzima bypass sentliziyo. stents Kwakhona senhliziyo - njengenye indlela thrombolysis kunye nobuchwepheshe ilungileyo yonyango iqhosha etsolo engabalulekanga ngqo kwiiyure lokuqala lophuhliso wayo.

Nangona kunjalo, kukho Izimo kule nkqubo. Stent nokubekwa akwenzeki kunye exineneyo ehlasela kwemithambo yenhliziyo. Kwakhona, isikhubekiso gqithi lincinane (ngaphantsi kwe 2.8 mm) ubukhulu kwemithambo iingqameko.

Yokuthintela iziganeko thrombotic le lenquba yenzelwa phezu imvelaphi anticoagulants.

Emva msebenzi, isigulana uhlala esibhedlele iintsuku 5-7 ngeenxa kweliso zonyango clock. Postoperatively uyaqhubeka antiplatelet kunye anticoagulation therapy.
