Munzvimbo yemishonga yemazuva ano, kunyanya mumunda wekupindira cardiology uye neurology, stents uye coils vanoita basa rakakosha. Nekudaro, vanhu vazhinji vanogona kuvhiringika pamusoro pekuti chii chaizvo chinosiyanisa izvi zviviri zvekurapa zvishandiso. Mune ino blog post, isu tichaongorora akasiyana maitiro, mashandisiro, uye maitiro aanoita kuti akubatsire iwe kuwana kunzwisisa kwakajeka.
Stent chinhu chidiki, tubular, mesh-like mudziyo, unowanzo gadzirwa nesimbi alloys sesimbi isina tsvina kana nickel-titanium (Nitinol). Yakagadzirwa kuti iiswe mumudziyo wakatetepa kana wakavharika weropa, duct, kana zvimwe zvimiro zvetubular mukati memuviri.
Kana murwere aine atherosclerosis, semuenzaniso, izvo zvinoita kuti tsinga dziteterere nekuda kwekuvakwa kweplaque, stent inogona kushandiswa. Munguva yeangioplasty maitiro, catheter ine bharumu yakasvibiswa uye stent yakasungirirwa inosungirirwa kuburikidza nemidziyo yeropa kusvikira yasvika panzvimbo yakakanganiswa. Kana yangove panzvimbo, bharumu inoputirwa, ichiwedzera stent uye kusundira plaque pamadziro etsinga, nokudaro kuwedzera lumen yemudziyo weropa. Iyo stent inobva yaramba iri panzvimbo zvachose, ichiita sechikafu chekuchengetedza chikepe chakavhurika uye kuve nechokwadi chekuyerera kweropa. Izvi zvinobatsira kubvisa zviratidzo zvakadai sekurwadziwa kwechipfuva (angina) uye kuderedza njodzi yekurwadziwa kwemoyo.
Stents inogona zvakare kuve-eluting zvinodhaka, zvichireva kuti vanoburitsa mishonga zvishoma nezvishoma nekufamba kwenguva kuti vawedzere kudzivirira restenosis, kutetepa zvakare kwemudziyo mushure mekutanga kurapwa.
Makoiri, kune rumwe rutivi, akatetepa, senge-waya zvimiro, anowanzo gadzirwa neplatinamu kana zvimwe biocompatible zvinhu. Izvo zvinonyanya kushandiswa mukurapa aneurysms, izvo zvisina kujairika bulges mumadziro etsinga dzeropa, anowanzo kuwanikwa muuropi.
Mune nzira inonzi endovascular embolization, catheter inotungamirirwa muaneurysm sac. Zvadaro, makoiri madiki anonyatsopinzwa kuburikidza necatheter uye osundirwa muaneurysm. Aya makoiri akagadzirirwa kuzadza aneurysm cavity, zvichiita kuti ropa riri mukati rivhare. Nekuvhara ropa, aneurysm inonyatsoparadzaniswa kubva kune yakajairwa kutenderera, inoderedza njodzi yekuputika, izvo zvinogona kutungamirira kuhupenyu hunouraya.
Kusiyana nemastents, makoiri haapi tsigiro yechimiro chekuchengetedza ngarava yakavhurika. Pane kudaro, chinangwa chavo ndechekuvhara, kana kuvharira, nzvimbo chaiyo kudzivirira zvinogona kuita njodzi.
- Design: Sezvambotaurwa, stents ane tubular uye mesh-senge, achipa yakavhurika furemu inobata madziro emudziyo akaparadzana. Macoils, mukupesana, anochinjika waya maumbirwo anoitirwa kuzadza uye kuvhara imwe nzvimbo.
- Function: Stents inotarisana nekuchengetedza patency, kana kuvhurika, kwemudziyo, zvichibvumira kuenderera mberi kweropa. Makoiri anoshandiswa kumisa kuyerera kweropa munzvimbo chaiyo, isina kujairika kudzivirira mamiriro ane njodzi.
- Nzvimbo dzekushandisa: Stents anonyanya kushandiswa mu coronary arteries (moyo), peripheral arteries (makumbo, maoko), uye zvimwe zviitiko mu carotid arteries (mutsipa). Coils anonyanya kushandiswa mukurapa intracranial aneurysms, kunyangwe iwo anogona zvakare kushandiswa mune mamwe vascular anomalies mune zvisingawanzo zviitiko.
Kana iwe kana mudikanwi wakatarisana nechirongwa chekurapwa chinogona kusanganisira stent kana coil, zvakakosha kuti uite hurukuro yakadzama nachiremba wako. Nzwisisa njodzi dzinogona kuitika uye zvakanakira sarudzo yega yega. Kune stents, njodzi dzinogona kusanganisira restenosis, kuumbwa kweropa kugadzika pamusoro pe stent pamusoro, uye zvinogoneka zvinokonzeresa zvinokonzeresa kune stent zvinhu. Nemakoiri, pane mukana wekuti aneurysm inogona kusavharika zvachose, zvichiita kuti idzoke, uye maitiro acho anogona kutakura njodzi sekubuda ropa kana kukuvadzwa kwematishu akatenderedza.
Mukupedzisa, nepo ese mastents nemakoiri ari anoshamisa zvigadzirwa zvekurapa zvakachengetedza hupenyu husingaverengeki, zvakagadzirirwa zvinangwa zvakasiyana kwazvo. Kuziva mutsauko kunogona kupa varwere simba rekuita zvisarudzo zvine ruzivo nezvehutano hwavo. Zvingave zvekuchengetedza tsinga dzemwoyo dzichiyerera zvakasununguka kana kuchengetedza uropi kubva pakutyisidzirwa kwekuputika kweaneurysm, iyi michina iri pamberi pemishonga yemazuva ano yekurapa.
Tinovimba kuti chinyorwa ichi chajekesa chakavanzika chiri pakati pemastendi nemakoiri uye kuti uchagovera ruzivo urwu nevamwe vangangoona ruchibatsira. Ramba wakatarisa kuti uone zvakadzama mamwe madingindira anonakidza ezvekurapa.
