Pazamankhwala amakono, makamaka pankhani ya cardiology ndi minyewa, ma stents ndi ma coil amagwira ntchito yofunika kwambiri. Komabe, anthu ambiri akhoza kusokonezeka ponena za zomwe zimasiyanitsa zida ziwirizi. Mu positi iyi yabulogu, tiwona mawonekedwe, ntchito, ndi momwe zimagwirira ntchito kuti zikuthandizeni kumvetsetsa bwino.
Stent ndi kachipangizo kakang'ono, kachubu, kokhala ngati mauna, komwe nthawi zambiri kamapangidwa ndi zitsulo zachitsulo monga chitsulo chosapanga dzimbiri kapena nickel-titanium (Nitinol). Amapangidwa kuti alowetsedwe mumtsempha wopapatiza kapena wotsekeka wamagazi, njira, kapena zida zina za tubular mkati mwa thupi.
Ngati wodwala ali ndi atherosulinosis, mwachitsanzo, zomwe zimapangitsa kuti mitsempha ikhale yocheperako chifukwa cha kuchuluka kwa zolembera, stent ingagwiritsidwe ntchito. Panthawi ya angioplasty, catheter yokhala ndi baluni yowonongeka ndipo stent yomwe imamangiriridwa imadutsa mumitsempha yamagazi mpaka ikafika pamalo okhudzidwa. Ikakhazikika, baluniyo imawonjezedwa, kukulitsa stent ndikukankhira zolembera pamakoma a mitsempha, motero amakulitsa lumen ya mtsempha wamagazi. Kenako stent imakhalabe nthawi zonse, imagwira ntchito ngati scaffold kuti chombocho chitseguke ndikuonetsetsa kuti magazi akuyenda bwino. Izi zimathandiza kuthetsa zizindikiro monga kupweteka pachifuwa (angina) ndikuchepetsa chiopsezo cha matenda a mtima.
Ma stents amathanso kutulutsa mankhwala osokoneza bongo, kutanthauza kuti amamasula mankhwala pang'onopang'ono pakapita nthawi kuti atetezere restenosis, kuchepetsanso chotengera pambuyo pa chithandizo choyambirira.
Komano, ma coils ndi opyapyala, okhala ngati mawaya, omwe nthawi zambiri amapangidwa ndi platinamu kapena zinthu zina zogwirizana ndi bio. Amagwiritsidwa ntchito makamaka pochiza matenda a aneurysms, omwe ndi zotupa zachilendo m'mitsempha yamagazi, zomwe zimapezeka kwambiri muubongo.
Mu njira yotchedwa endovascular embolization, catheter imalowetsedwa mu thumba la aneurysm. Kenako, timizere tating'onoting'ono timalowetsedwa mosamala kudzera mu catheter ndikukankhira mu aneurysm. Zozungulira izi zimapangidwa kuti zizidzaza mtsempha wa aneurysm, zomwe zimapangitsa kuti magazi mkati mwake atseke. Mwa kutsekeka kwa magazi, aneurysm imasiyanitsidwa bwino ndi kayendedwe kabwino, kuchepetsa chiopsezo cha kupasuka, zomwe zingayambitse kutaya kwa moyo.
Mosiyana ndi ma stents, ma coil samapereka chithandizo chothandizira kuti chombocho chitseguke. M'malo mwake, cholinga chawo ndi kutsekereza, kapena kutsekereza, malo enaake kuti apewe zotsatira zowopsa.
- Kupanga: Monga tafotokozera, ma stents ndi ma tubular ndi ma mesh, omwe amapereka chimango chotseguka chomwe chimagwirizanitsa makoma a chombo. Ma coils, mosiyana, ndi mawonekedwe a waya osinthika omwe amayenera kudzaza ndi kutseka malo enaake.
- Ntchito: Ma stents amayang'ana kwambiri kusunga patency, kapena kutseguka, kwa chotengera, kulola kuti magazi apitirize kuyenda. Ma coils amagwiritsidwa ntchito kuti magazi asiye kuyenda pamalo enaake, osadziwika bwino kuti apewe ngozi.
- Magawo Ofunsira: Ma stents amagwiritsidwa ntchito kwambiri m'mitsempha ya coronary (mtima), mitsempha yotumphukira (miyendo, mikono), komanso nthawi zina m'mitsempha ya carotid (khosi). Ma coils amagwiritsidwa ntchito kwambiri pochiza matenda a intracranial aneurysms, ngakhale atha kugwiritsidwanso ntchito pazovuta zina zam'mitsempha nthawi zambiri.
Ngati inu kapena wokondedwa wanu mukukumana ndi chithandizo chamankhwala chomwe chingaphatikizepo stent kapena coil, ndikofunikira kukambirana mozama ndi dokotala wanu. Kumvetsetsa zoopsa zomwe zingatheke komanso ubwino wa njira iliyonse. Paziwopsezo, zowopsa zingaphatikizepo restenosis, kupangika kwa magazi pa stent pamwamba, komanso kusagwirizana ndi zinthu zomwe zingachitike. Ndi ma coil, pali mwayi woti aneurysm isatsekeke kwathunthu, zomwe zimatsogolera kubwereza, ndipo njira yokhayo imatha kukhala ndi zoopsa monga kutuluka magazi kapena kuwonongeka kwa minofu yozungulira.
Pomaliza, ngakhale kuti ma stents ndi ma coil ndi zida zotsogola zachipatala zomwe zapulumutsa miyoyo yambiri, zidapangidwira zolinga zosiyana kwambiri. Kudziwa kusiyana kungathandize odwala kupanga zisankho zodziwika bwino pazaumoyo wawo. Kaya ndi kusunga mitsempha ya mtima ikuyenda momasuka kapena kuteteza ubongo ku chiopsezo cha kupasuka kwa aneurysm, zipangizozi zili patsogolo pa chithandizo chamankhwala chamakono.
Tikukhulupirira kuti nkhaniyi yawunikira zachinsinsi pakati pa ma stents ndi ma coil ndikuti mugawana chidziwitsochi ndi ena omwe angachipeze kukhala chothandiza. Khalani tcheru kuti mumve mozama nkhani zina zachipatala zochititsa chidwi.
