Ingabe umthambo wakho wenhliziyo uvaliwe? Konke mayelana ne-stent, kalula nje!

Wake wezwa ngokufakwa kwe-"stent"? Mhlawumbe uke wezwa ngomunye wamalungu omndeni wakho noma abangani bakho enayo. Ngokuvamile, igama elithi stent livela uma kunenkinga yenhliziyo. Ngakho-ke, iyini i-stent? Kungani lezi zinto zifakwa? Ake sixoxe ngalokhu ngokuningiliziwe namuhla, kulungile?

Iyini i-stent?

Kalula nje, i-stent iyipayipi elincane kakhulu, elifana ne-mesh. Lifana nengxenye ye-mesh esongiwe. Yilokhu udokotela wakho angakufaka ngaphakathi komunye wemithambo yakho yegazi, noma imithambo yegazi, bese ewugcina uvulekile. Cabanga ukuthi umthambo wegazi une -plaque , noma i-cholesterol, evimba ukugeleza kwegazi. Udokotela uzoqala asuse i-plaque bese evula indlela. Ngemuva kwalokho bazofaka i-stent endaweni ukuze bavimbele umthambo ukuthi ungaphinde uvaleke. Kufana nokuthile okufakayo ukulawula ukuminyana kwezimoto. Kusiza ukugeleza kwegazi kalula .

Le stent ivame ukufakwa unomphela ngaphakathi kwemithambo yakho yegazi (ezinye izinhlobo ezincibilikayo seziyatholakala manje, kodwa ezihlala njalo yizona ezivame kakhulu). Zivame ukwenziwa ngensimbi. Kodwa-ke, ezinye izinhlobo ezikhethekile zama-stent zenziwa ngezinye izinto. I-stent yenhliziyo, efakwa emithanjeni yenhliziyo, ingaba noma yikuphi ubude obungamamilimitha angu-8 kuya kwangu-48, noma cishe amasentimitha angu-2. Ingaba cishe amamilimitha angu-2 kuya kwangu-5 ububanzi. Lokho kucishe kube usayizi wesihloko sekhrayoni entsha noma usayizi we-eraser entsha yepensela. Kodwa-ke, ama-stent abekwa kwezinye izindawo angaba makhulu kakhulu.

Ibekwa kuphi i-stent?

Abantu abaningi bacabanga ukuthi ama-stents asetshenziswa kuphela emithanjeni yegazi yenhliziyo. Kodwa lokho akulona iqiniso. Ngaphezu kwemithambo yegazi, odokotela basebenzisa nama-stents ukuvimbela izinto ezifana nemigudu yomoya , imigudu ye-bile , kanye nama-ureter ukuthi angavaleki. Kodwa ama-stents afakwa emithwalweni yomoya avame ukusetshenziswa njengesixazululo sesikhashana kuze kube yilapho kwenziwa ukuhlinzwa okukhulu.

Yiziphi izinhlobo zama-stents akhona?

Kunezinhlobo ezahlukene zama-stents. Ake sibheke ezimbalwa zezinhlobo eziyinhloko.

I-Stent Yensimbi Engenalutho

Lezi zenziwe ngezinsimbi kuphela, isibonelo `(i-nickel-titanium alloy)`, `(insimbi engagqwali)` noma `(i-cobalt-chromium)`. Lezi ubuchwepheshe obudala obusetshenziswe isikhathi eside. Zifakwa emithanjeni yenhliziyo yakho (imithambo ye-coronary) noma emithanjeni entanyeni yakho (imithambo ye-carotid).

I-Stent Engasebenzisi Izidakamizwa

Lolu uhlobo oluthandwa kakhulu olusetshenziswa namuhla. Insimbi yale stent inomuthi okhethekile osetshenziswa kuyo. Lo muthi uvimbela umthambo lapho kufakwa khona i-stent ukuthi ungaphinde unciphe. Okusho ukuthi, uvimbela ukwakheka okungadingekile kwezicubu zesilonda ngaphakathi kwe-stent.Lo muthi uvimba ukwakheka kwemithambo yegazi ezinyangeni ezimbalwa zokuqala. Lokhu kugcina umthambo wegazi uvulekile.

I-Stent Ebolayo

Lobu ubuchwepheshe obusha. Busasetshenziswa kancane. Ngemva kokuba lolu hlobo lwe-stent lufakwe emthanjeni, luyancibilika emzimbeni zingakapheli izinyanga ezimbalwa . Lokhu kusho ukuthi akudingeki ugcine ucezu lwensimbi emzimbeni wakho unomphela.

Indwangu ye-polyester kanye ne-stent yensimbi

Lezi yizinti ezinkulu kancane. Zisetshenziswa emithanjeni yegazi emikhulu njenge-aorta. Zenziwe ngendwangu ye-polyester nensimbi.

I-Silicone Stent

Odokotela basebenzisa lokhu ukugcina indlela yokuphefumula ivulekile emaphashini akho .

Kungani kufanele usebenzise i-stent?

Odokotela basebenzisa ama-stent ikakhulukazi ukuvimba ukugeleza kwegazi ekuvinjweni ukuncipha noma ukuvaleka ngokuphelele komthambo wegazi. Ungadinga i-stent uma:

• Uma unesifo senhliziyo .
• Uma une -atherosclerosis , okusho ukuthi amafutha aqongelelene ngaphakathi kwemithambo yegazi, okunciphisa ukuhamba kwegazi.
• Uma imithambo yakho engaphezu kuka-70% ivalekile kakhulu .

Ngokwesibonelo, ake ucabange ukuthi ipayipi lamanzi engadini yakho livalekile ngotshani nokungcola, okwenza amanzi ageleze kancane noma ame ngokuphelele. I-stent iyisisekeli esincane esifakwa ngaphakathi kwepayipi, okuvumela amanzi ukuthi ageleze kahle futhi.

Yiziphi izimo eziphathwa nge-stent?

Ngokususa ama-fatty deposits ngaphakathi kwemithambo yegazi ngokufaka i-stent, imithambo yegazi ingasebenza kahle futhi. Ama-fatty deposits angenzeka ezimweni ezifana nalezi:

• Isifo semithambo yegazi engaphandle (i-PAD)
• Isifo semithambo ye-carotid.
• Isifo semithambo yezinso.
• Isifo semithambo yegazi ye-coronary.

Ngaphezu kwalokho, ukufakwa kwe-stent kungasiza nabantu abanezimo ezifana ne-deep vein thrombosis (DVT) (engenzeka emilenzeni, ezingalweni, noma ethangeni) kanye ne-aortic aneurysm.

Ivame kangakanani i-stent?

Ezweni elifana ne-United States kuphela, kuthiwa kwenziwa ukuhlinzwa kwe-stent yenhliziyo okungaba ngu-600,000 minyaka yonke. Isikhathi sokuqala i-stent yafakwa enhliziyweni yomuntu kwakungo-1986. Kusukela ngaleso sikhathi, ukusetshenziswa kwe-stent kwande kakhulu. Lokhu sekuyinto evamile naseSri Lanka.

Yiziphi izinzuzo zokufakwa kwe-stent?

Kunezinzuzo eziningana zokubeka i-stent:

• Ukugeleza kwegazi kuhle ngemithambo yegazi lapho kwafakwa khona i-stent.
• Uma kuhlanganiswa nokwelashwa okubizwa ngokuthi i-angioplasty, kungamisa ukuhlaselwa yinhliziyo.
• Unayo ini?Izimpawu ezifana nokuphelelwa umoya kanye nobuhlungu besifuba ziyancishiswa (ikakhulukazi ngemva kokufakwa kwe-stent emthanjeni wenhliziyo).
• Kungavimbela umthambo wakho ukuthi ungaphinde unciphe.
• Umuntu ofakwe i-stent angalulama ngokushesha kunomuntu ohlinzwe nge-coronary artery bypass (CABG) ngoba ukufakwa kwe-stent kuyinqubo engangenisi kakhulu eyenziwa ngokusikwa okuncane.

Cabanga nje, lapho uzizwa ubuhlungu esifubeni ngokuzumayo, unenkinga yokuphefumula, bese uya esibhedlela, bese odokotela bethi umthambo wegazi enhliziyweni yakho uvaliwe futhi udinga ukufaka i-stent ngokushesha. Le divayisi encane ingaba yithuluzi elisindisa impilo elingakanani ngaleso sikhathi?

Yiziphi izingozi noma izinkinga zokufakwa kwe-stent?

Izinkinga ezinkulu ezivela ekufakweni kwe-stent azivamile, kodwa abantu abanesifo senhliziyo, isifo sikashukela, isifo sezinso, noma ukuvaleka kwemithambo yegazi ngaphambilini basengozini enkulu yezinkinga ezinkulu.

Nazi ezinye zezingozi ezingaba khona:

• Kungase kwakheke ihlule legazi ngaphakathi kwe-stent. Lokhu kungenzeka, ikakhulukazi uma uyeka ngokuzumayo ukuphuza umuthi ovikela i-stent.
• Ukusabela kokungezwani komzimba ne-stent uqobo noma umuthi osetshenziswa kuyo.
• Ukopha okuvela endaweni lapho udokotela ayesebenzisa khona ukungena emthanjeni wegazi.
• Ukutheleleka.
• Ukudabuka ngaphakathi komthambo.
• I-Arrhythmia (ukushaya kwenhliziyo okungajwayelekile).
• Ukopha ngenxa ye-stent noma ukunyakaza okuvela endaweni yayo.
• Ukuwa/ukuqhuma kwamaphaphu `(Pneumothorax)`.
• Bese umthambo uncipha futhi (i-Restenosis).
• Ukuhlaselwa yinhliziyo noma ukuboshwa kwenhliziyo.
• Isimo esifana nesohlangothi.

Lezi zinto zingase zesabe kancane ukuzwa. Kodwa khumbula, lezi zinto azivamile. Udokotela wakho uzokwazisa ngazo zonke lezi zinto.

Ingabe ngidinga ukuthatha imithi ngemva kokufakwa i-stent?

Yebo, impela. Udokotela wakho uzokubhalela imithi yokulwa nama-platelet . Le mithi isebenza ngokuvimbela ama-platelet, angamaseli egazi, ukuthi angahlangana ndawonye ku-stent bese enza i-blood clot. Uma i-clot enjalo ivele, ingavimba umthambo futhi.

Kuzodingeka uphuze umuthi ofana ne -aspirin impilo yakho yonke, kanye nomunye umuthi unyaka noma ngaphezulu. Lokhu kubizwa ngokuthi ukwelashwa okulwa nama-platelet amabili (i-DAPT) ngoba kusebenzisa izinhlobo ezimbili zemithi.

Abacwaningi basabheka ukuthi kufanele uthathe lo muthi isikhathi esingakanani. Lapho bekunikeza lo muthi, odokotela bacabangela izici eziningi, njengobudala bakho, ubulili, indlela yokuphila, ezinye izimo zezokwelapha, kanye nohlobo lwe-stent onayo.

Into ebaluleke kakhulu ukuthi, ungayeki ukuthatha lo muthi nganoma yisiphi isizathu ngaphandle kokuthi udokotela wakho akutshele ukuthi uyeke. Ukuwuyeka kungabangela izinkinga ezinkulu.

Ungase uzizwe ungajwayelekile ngokuba nento eyenziwe ngokwenziwa emzimbeni wakho. Kodwa odokotela bebelokhu besebenzisa ama-stents iminyaka eminingi, futhi izinkampani eziwenzayo zihlala ziwathuthukisa. Uma ufunda kabanzi ngawo futhi ubuza udokotela wakho imibuzo, ungasiza ekunciphiseni ukwesaba kwakho ngokuba ne-stent.

Okokugcina, izinto okufanele uzikhumbule

I-stent iyithuluzi elincane, kodwa elinamandla kakhulu elisiza ukugcina iziteshi ezivaliwe zivulekile, hhayi enhliziyweni kuphela, kodwa nakwezinye izingxenye zomzimba.

• Kuthuthukisa ukujikeleza kwegazi, kunciphisa izimpawu, futhi ngezinye izikhathi kusindisa ngisho nokuphila.
• Kunezinhlobo ezahlukene zama-stents, futhi udokotela wakho uzokhetha uhlobo olukufanele kakhulu.
• Nakuba kunezingozi ezithile, azivamile kakhulu. Izinzuzo zidlula zona.
• Ngemva kokufakwa i-stent, kubaluleke kakhulu ukuthatha imithi udokotela wakho ayinikezayo ngqo futhi isikhathi eside njengoba ekutshela.

Ngakho-ke, ngithemba ukuthi usuyaqonda kangcono i-stent. Uma unemibuzo, ungangabazi ukubuza udokotela wakho. Hlala uphilile!

I- Stent, ukuhlaselwa yinhliziyo, ukuvaleka kwemithambo yegazi, i-angioplasty, i-cholesterol, imithambo yegazi, impilo yenhliziyo
