Ni bangahe Stent izi - Kubara izo "Urufunguzo Ruto" Ntabwo Imitsi

Iyo bigeze kuri stent, izwi cyane ni stente y'amaraso (nka coronary na peripheral vascular stents). Stenosis ikabije yimiyoboro yamaraso irashobora gutuma igabanuka ryubuzima bwabarwayi ndetse bikanabangamira ubuzima bwabo. Kubwibyo, hagomba gushyirwaho stent kugirango igarure amaraso. Ariko hariho imiyoboro yamaraso gusa mumiyoboro migufi yumubiri wumuntu? Igisubizo byanze bikunze. Ibibyimba bitari imitsi nka esofagusi, inzira z'ubuhumekero, inzira ya biliary, hamwe n'inzira zo munda mu mubiri w'umuntu nazo zirashobora kugabanuka kubera impamvu zimwe na zimwe (ibibyimba, fistule anastomotique, nibindi), bikavamo ibimenyetso nko kugora kurya cyangwa guhumeka, jaundice .

1.Entophageal stent:

Esophageal stenosis ikubiyemo stenosis nziza kandi mbi, ishobora gutera ibimenyetso nkikibazo cyo kumira abarwayi. Benign stenosis iterwa ahanini n'indwara ya gastroesophageal reflux, kubagwa, kuvura imirasire, kuvura ablation, kwangirika kwangirika, no kwangiza ibiyobyabwenge, kandi birashobora kuvurwa hakoreshejwe stent by'agateganyo (ubusanzwe bitwikiriye stent, bikurwaho mugihe cy'ukwezi); Indwara ya Esophageal stenosis iterwa ahanini na kanseri yo mu nda, indwara mbi zo mu gatuza, hamwe no kubyimba ibibyimba bibi muri esofagus. Kugeza ubu, gukoresha stent esophageal kugirango ugabanye Esophageal stenosis yabaye uburyo bwingenzi bwo kuvura indwara mbi ya Esophageal stenosis.

Igipimo cyo gushyira mu bikorwa inkunga ya esophageal

Birakwiye kuvura imiti igabanya ubukana cyangwa mbi, gukomera kwa anastomotique, no gukomera nyuma ya radiotherapi.

2. Guhumeka

Inzira z'ubuhumekero zigabanyijemo inzira zo mu myanya y'ubuhumekero yo hejuru no hepfo, kandi infarction yo mu kirere irashobora gutera ibimenyetso nko guhumeka neza no guhumeka neza. Umwuka wo mu kirere bivuga kugabanuka kwa trachea na bronchial lumens biterwa n'indwara zitandukanye zo mu kirere cyangwa mbi. Impamvu zitera umwuka mwiza wo mu kirere harimo igituntu cya tracheobronchial igituntu, intubation ya tracheal igihe kirekire cyangwa tracheostomy, sarcoidose, tracheobronchial amyloidose, nibindi; Indwara mbi iterwa n'ibibyimba by'ibanze cyangwa metastatike ya trachea, karina, ibumoso n'iburyo nyamukuru bronchi, hamwe na bronchi yo hagati, hamwe n'ibibyimba bibi byinjira cyangwa bikomeretsa ingingo zegeranye.

Ingano ikoreshwa yubuhumekero

Birakwiye kuvura kwaguka kwa benigne cyangwa malignant stenosis ya trachea na bronchus.

3.Biliary stent

Sisitemu ya biliary ifite umurimo wo gusohora, kubika, kwibanda, no gutwara ibibyimba, bigira uruhare runini mugusohora imyanda muri duodenum. Niba hari ibisebe byiza cyangwa bibi mu muyoboro wa bili cyangwa ibice byegeranye byumuyoboro wa bilide, bizabangamira urujya n'uruza rwinjira muri duodenum binyuze mu muyoboro w’umuyoboro, bitera kwiyongera k'umuvuduko mu muyoboro w'inda, bigatuma umwijima uva mu mwijima selile na capillaries mumaraso ya sinus na perisinus, bigatuma kwiyongera kurwego rwa bilirubine conjugated mumaraso bigatera jaundice. Indwara mbi ya jaundice iterwa n'ibibyimba, kandi iyo inzitizi imara igihe kinini, irashobora kwangiza imikorere yibikorwa byingenzi. Kugeza ubu, gutera biliary stent byahindutse uburyo bwingenzi bwo kuvura, bushobora kugabanya cyangwa gukuraho jaundice, kuzamura abarwayi muri rusange, no kuzamura imibereho yabo.

Ingano ikoreshwa ya biliary stent

Ahanini ikoreshwa mukuvura biliary stenosis.

4.Intambwe yo munda

Amara ni imiyoboro miremire mu ngingo zifungura, harimo duodenum, jejunum, ileum, cecum, colon, na rectum. Iyo amara yo mu nda cyangwa inzitizi biterwa nibibyimba bibi byateye imbere cyangwa ibindi bikomere bibi munda, birashobora gutera ingorane zo gusya ibiryo, kubyakira, no kwiyuhagira. Gukoresha ibyuma byuma kugirango ushyigikire burundu cyangwa by'agateganyo agace kagabanijwe cyangwa kabujijwe mu mwobo w'amara birashobora kugarura ubwitonzi no gushiraho uburyo bwo kubagwa neza.

Igipimo cyo gushira mu mara

Birakwiye kuvura kwaguka kuvura amara, guhagarika, cyangwa stastose ya anastomotique mumubiri wumuntu (duodenum, transvers colon, colon des down, sigmoid colon, rectum).
