Restenosis imatanthawuza kubwezeretsa pang'onopang'ono mitsempha yowonongeka pambuyo poti chitetezo chakhala chikuchiritsidwa ndi angioplasty ndi stenting . Ngati restenosis imachitika, kawirikawiri imachitika mkati mwa miyezi itatu kapena 12 ya ndondomekoyi. Chifukwa restenosis imachititsa kuti mitsempha ikhale yopapatiza, zizindikiro za angina kawirikawiri kubwerera.
Restenosis inadziwika ngati vuto m'masiku akale kwambiri a angioplasty, omwe amapezeka pafupifupi 40 mpaka 50% mwa anthu omwe anadwala angioplasty okha.
Ndipotu, chifukwa choyambira chinakhazikitsidwa pamalo oyamba chinali kuchepetsa chiwerengero cha kupuma.
Kukula kwakukulu, zintchito zakhala zikupambana pochita izi. Ngakhale ndi mibadwo yoyamba yopanda zitsulo (BMS), chiwerengero cha restenosis chinachepetsedwa (pafupifupi 20 - 30% mu miyezi 12). Pambuyo pake, mankhwala osokoneza bongo (DES) adayambitsidwa pofuna kuyesa kuchepetsa kupumula. Mu DES, mphunoyi ili ndi mankhwala osokoneza bongo omwe amaletsa kukula kwa minofu yomwe imatsogolera ku restenosis.
Mbadwo woyamba wa DES unachititsa kuti chiwerengero cha restenosis chikhale pafupifupi 15% pa zaka zisanu. Zatsopano zachepetsa kuchepa kwapadera, pafupifupi 5 mpaka 7% pazaka zisanu.
Nchiyani Chimachititsa Restenosis?
Angioplasty (ndi malo osungirako malo, chifukwa nthawi zonse amakhala limodzi ndi angioplasty) ndi mawonekedwe a minofu. Pakati pa angioplasty, kathette yokhala ndi bulloon yofiira imadutsa pamatope a atherosclerotic mu mitsempha yamakono, ndipo apo baluni imakhuta.
Kutsika kwa buluni kumaphatikizapo chipikacho, motero kumachepetsa kutsegula kwa mitsempha. Phokoso - kachitidwe kakang'ono kakang'ono - kenaka amakula pa malo a angioplasty, kuti mitsempha yowonjezera isagwe pansi. Kupanikizika (kapena "smashing," ngati mukufuna) pa chipika si njira yokoma, ndipo nthawi zonse kumapangitsa chiopsezo ku khoma la zitsulo zamagazi.
Restenosis imapezeka chifukwa cha kukula kwa minofu pamalo a mankhwala. Zingatheke kuganiziridwa ngati zotsatira za "machiritso" ndondomeko pambuyo pa zoopsa zazing'onoting'ono za angioplasty. Maselo otsirizira omwe nthawi zambiri amatha kugwiritsa ntchito mitsempha yowonjezereka pa malo a zovutazo. Ngati kuchuluka kwa maselo otsirizirawo kumakhala kochuluka, maselo amatha kulepheretsa chotengera cha magazi pamalo a stent.
Restenosis ikhozanso kupezeka chifukwa cha matenda omwe amachititsa kuti matenda a atherosclerosis awonongeke. Restenosis yomwe imayambitsa matenda a atherosclerosis amaoneka ngati nthawi yayitali mutatha njirayi - chaka kapena kuposerapo. Pafupipafupi, nthawi zambiri mumakhala miyezi isanu ndi umodzi, ndipo nthawi zambiri mumatha miyezi 12 mutatha njirayi, kawirikawiri imayamba chifukwa cha kukula kwa minofu.
Restenosis vs. Thrombosis
Restenosis sichimodzimodzi ndi mantha omwe amawopsa kwambiri - kutuluka mwadzidzidzi kwa stent kuchokera pakupanga magazi. Thrombosis imakhala yoopsa, chifukwa nthawi zambiri imatulutsa mitsempha mwadzidzidzi komanso yodzaza. Mavuto a thrombosis ndi apamwamba kwambiri masabata angapo kapena miyezi ingapo pambuyo poika malo, koma amachepetsedwa kwambiri pogwiritsa ntchito mankhwala osokoneza bongo .
Palinso chiopsezo chaching'ono koma chenichenicho cha msuzi wa thrombose wam'munsi - thrombosis yomwe imachitika chaka kapena kuposerapo pamene mbolayi imayikidwa - ndipo zaka zaposachedwapa zakhala zikuonekeratu kuti mankhwala osokoneza bongo ayenera kupitilizidwa kwa chaka chimodzi . Komabe, njira yabwino yothetsera kutsekemera kochedwa stent thrombosis, komabe, ikutsutsanabe.
Kodi Restenosis Imachitika Bwanji?
Pamene kugwiritsidwa ntchito kwa DES kwachepetsa kwambiri chiŵerengero cha stent restenosis, sichinathetse vutoli.
Ngati restenosis imachitika ndipo ikuonetsa zizindikiro za angina, nthawi zambiri chithandizo chimaphatikizapo ndondomeko yobwereza - makamaka, kuika kwa stent yachiwiri pamalo omwewo.
Chithandizo chamankhwala (chosachiritsika) cha angina chimakhalanso njira ina. Mitsempha ya Coronary kupyolera mu opaleshoni ndi njira ina kwa anthu okhala ndi sten restenosis, makamaka ngati restenosis imatuluka pambuyo stent yachiwiri.
Chidule
Restenosis poyamba inali yaikulu mwa kugwiritsa ntchito angioplasty ndi stents kwa matenda a mitsempha ya mitsempha. Pamene zipangizo zamakono zapamwamba zasintha, restenosis tsopano yakhala yovuta kwambiri. Komabe, kugwiritsiridwa ntchito kwa mbola zamakono kwawonetsa vuto lina la kasamalidwe ku chisamaliro cha matenda a mitsempha ya matenda. Njira yabwino yochepetsera chiopsezo cha vuto latsopanoli ikugwiritsidwabe ntchito.
