Renal Artery Stenosis

Renal artery stenosis ni ukubura kw'imijyana imwe cyangwa irenga itwara amaraso ajya mu mpyiko zawe (renal arteries). Kugabanyuka kw'imijyana bituma amaraso ahagije akungahaye kuri ogisijeni adashobora kugera ku mpyiko zawe. Impyiko zawe zikenera amaraso ahagije kugira ngo afashe gukuraho ibintu byangiza n'amazi y'umubiri arenze urugero. Kugabanuka kw'amaraso ajya mu mpyiko bishobora gukomeretsa imyanya y'impyiko no kongera umuvuduko w'amaraso mu mubiri wawe.

Impatwe ya artery ya renal ikunze kutazigaragaza ibimenyetso cyangwa ibimenyetso kugeza igeze kure. Iyi ndwara ishobora kuvumburwa mu buryo butunguranye mu bipimo byakozwe ku kintu kindi. Umuganga wawe ashobora kandi gushidikanya ikibazo niba ufite: Umuvuduko ukabije w'amaraso utangira mu buryo butunguranye cyangwa ukamera nabi nta bisobanuro Umuvuduko ukabije w'amaraso utangira mbere y'imyaka 30 cyangwa nyuma y'imyaka 50 Uko impatwe ya artery ya renal igenda ikura, ibindi bimenyetso n'ibimenyetso bishobora kuba birimo: Umuvuduko ukabije w'amaraso ugora kugenzura Ijwi ryumvikana nk'umuyaga w'amaraso anyura mu mubiri mwinshi (bruit), muganga yumva akoresheje stethoscope ishyirwa hejuru y'impyiko Zanyu Imirimo y'impyiko iri hejuru mu mwanya cyangwa ibindi bimenyetso by'ikibazo cy'imikorere y'impyiko Imikorere y'impyiko irushaho kuba mbi mu gihe cyo kuvurwa umuvuduko ukabije w'amaraso Amazi menshi n'ububabare mu mubiri wawe Gucika intege kw'umutima bitavurwa Umuti w'umutima utaravurwa Nuhamagara muganga wawe niba ufite ibimenyetso cyangwa ibimenyetso biramba bikubangamiye.

Impamvu eza zibiri zikomeye ziterwa na stenosis y'imitsi y'impyiko ni:Ikurikiranwa ku mitsi y'impyiko.Ibinure, cholesterol n'izindi ntungamubiri (plaque) bishobora kwibasira no ku mitsi y'impyiko (atherosclerosis).Uko ibi bice byiyongera, bishobora gukomera, bigabanye umusaruro w'amaraso, bigateza ibikomere ku mpyiko kandi amaherezo bigatuma umusego ugabanyuka.Atherosclerosis iba mu bice byinshi by'umubiri kandi ni yo ntandaro ikomeye ya stenosis y'imitsi y'impyiko.

Fibromuscular dysplasia.Muri fibromuscular dysplasia, umusuli wo ku rukuta rw'umusego ntukura nkuko bikwiye.Ibi bikunda gutangira mu bwana.Umusego w'impyiko ushobora kugira ibice bito bivanze n'ibice binini, bigatanga isura isa n'amabuye mu mashusho y'umusego.Umusego w'impyiko ushobora kugabanyuka cyane ku buryo impyiko idashobora kubona amaraso ahagije.Ibi bishobora gutera umuvuduko ukabije w'amaraso mu gihe cy'ubuto.Ibi bishobora kuba ku mpyiko imwe cyangwa zombi.Impuguke ntizizi icyateza fibromuscular dysplasia, ariko iyi ndwara ikunze kugaragara mu bagore kandi ishobora kuba ikintu kiriho kuva ku ivuka (congenital).Imitsi y'impyiko yagabanutse na fibromuscular dysplasia bishobora kugira ingaruka ku zindi mitsi mu mubiri wawe kimwe n'imitsi y'impyiko yawe kandi bigateza ibibazo.Gake, stenosis y'imitsi y'impyiko iterwa n'izindi ndwara nko kwangirika kw'imitsi y'amaraso cyangwa ikintu gikura mu nda yawe kikamanika ku mitsi y'impyiko zawe.

Amakuru menshi y’ibibazo by’imitsi y’impyiko biterwa n’imitsi y’impyiko yagabanutse. Ibintu bishobora gutuma imitsi y’impyiko yagabanuka no mu ndi mitsi y’umubiri wose birimo: Kuvuka imyaka myinshi Guhindagurika kw’amaraso Amavuta menshi mu maraso Indwara ya sukari Kubyibuha Gutera itabi n’ibindi bikoresho by’itabi Ibyabaye mu muryango w’indwara y’umutima yabayeho mu myaka mike Kutagira umurimo wo gukora imikorere

Ingaruka zishoboka z'indwara ya renal artery stenosis zirimo:

• Kudakora neza kw'impumyi, bisaba kuvurwa hakoreshejwe imiti ya dialyse cyangwa gutera impumyi
• Kubika amazi mu birenge, bigatera kubyimba ibirenge cyangwa ibirenge
• Guhumeka nabi bitewe no kwiyongera kw'amazi mu bihaha mu buryo butunguranye

Mu gupima indwara y'imijyana y'impyiko, umuganga wawe ashobora gutangira afite: Isuzuma ngororamubiri ririmo umuganga wumva umutima hejuru y'impyiko, ashaka amajwi ashobora kugaragaza ko umwenda w'impyiko yawe ugoswe Suzuma amateka yawe y'ubuzima Ibizamini by'amaraso n'impiswi kugirango urebe imikorere y'impyiko zawe Ibizamini by'amaraso n'impiswi bipima urugero rw'imisemburo igenga umuvuduko w'amaraso Ibipimo byo kubona ishusho bikunze gukorwa kugirango hamenyekane indwara y'imijyana y'impyiko birimo: Doppler ultrasound. Amajwi y'umuvuduko mwinshi afasha muganga wawe kubona imijyana n'impyiko no kugenzura imikorere yayo. Ubu buryo kandi bufasha muganga wawe gushaka inzitizi mu mitsi y'amaraso no gupima uburemere bwazo. CT scan. Mu gihe cyo gukora CT scan, imashini ya X-ray ifitanye isano na mudasobwa ihanga ishusho ihamye igaragaza amashusho yaciwe y'imijyana y'impyiko. Ushobora guhabwa inshinge y'ibara kugirango igaragaze imiterere y'amaraso. Magnetic resonance angiography (MRA). MRA ikoresha amajwi ya radiyo n'imbaraga zikomeye za magneti kugirango ikore amashusho ya 3D y'imijyana y'impyiko n'impyiko. Injisi y'ibara mu mijyana igaragaza imijyana y'amaraso mu gihe cyo kubona ishusho. Renal arteriography. Ubu bwoko bw'ibizamini bya X-ray bufasha muganga wawe gushaka inzitizi mu mijyana y'impyiko, rimwe na rimwe agafungura igice cyagoswe hakoreshejwe umupira cyangwa stent. Mbere yuko X-ray ifatwa, muganga wawe ashyiramo ibara mu mijyana y'impyiko akoresheje umuyoboro muremure, mucyeya (catheter) kugirango agaragare imijyana n'imiterere y'amaraso neza. Iki kizamini gikorerwa ahanini niba bishoboka ko ukeneye umuyoboro muto (stent) ushyirwa mu mubiri wawe kugirango uwugurure. Kwitabwaho muri Mayo Clinic Itsinda ryacu ryita ku barwayi b'inzobere za Mayo Clinic rishobora kugufasha mu bibazo byawe by'ubuzima bifitanye isano n'indwara y'imijyana y'impyiko Tangira hano

Ubuvuzi bwa stenosis y'imitsi y'impyiko bushobora kuba burimo guhindura imibereho, imiti n'uburyo bwo gusubiza amaraso mu mpyiko. Rimwe na rimwe, guhuza ubuvuzi ari bwo buryo bwiza. Bitewe n'ubuzima bwawe rusange n'ibimenyetso, ushobora kutakeneye ubuvuzi bwihariye. Guhindura imibereho Niba umuvuduko w'amaraso ari hejuru cyane cyangwa cyane, imibereho myiza - kugabanya umunyu, kurya ibiryo byiza no gukora imyitozo ngororamubiri buri gihe - bishobora gufasha kugenzura umuvuduko w'amaraso. Imiti Umuvuduko w'amaraso uri hejuru - nubwo ahanini bijyanye na stenosis y'imitsi y'impyiko - akenshi ushobora kuvurwa neza hakoreshejwe imiti. Gushaka imiti ikwiye cyangwa guhuza imiti bishobora gusaba igihe no kwihangana. Imiti imwe ikoreshwa cyane mu kuvura umuvuduko w'amaraso uri hejuru ujyanye na stenosis y'imitsi y'impyiko irimo: Inhibitor z'enzyme ihindura angiotensin (ACE) na angiotensin II receptor blockers (ARBs), bifasha kwiruhura imitsi yawe y'amaraso no kuburizamo imiterere cyangwa ingaruka z'ikintu kamere cy'umubiri kitwa angiotensin II, gikata imitsi y'amaraso Diuretics, bizwi kandi nka pilule z'amazi, bifasha umubiri wawe gukuraho umunyu mwinshi n'amazi Beta blockers na alpha-beta blockers, bishobora kugira ingaruka yo gutuma umutima wawe ukubita buhoro kandi udashoboye cyangwa kwagura (kwagura) imitsi yawe y'amaraso, bitewe n'imiti ukoresha Calcium channel blockers, bifasha kwiruhura imitsi y'amaraso Niba atherosclerosis ari yo ntandaro ya stenosis y'imitsi y'impyiko, umuvuzi wawe ashobora kandi kugutegurira aspirine n'imiti igabanya cholesterol. Imiti ikurikiranye ni izihe ikurikiranye bitewe n'umwanya wawe bwite. Uburyo Bw'ubuvuzi Kuri bamwe, uburyo bwo kuvura bushobora gusabwa kugira ngo busubize amaraso mu mitsi y'impyiko kugira ngo buzamure amaraso ajya mu mpyiko. Ibyavuye mu bushakashatsi bw'ibizamini bigereranya imiti hamwe na angioplasty y'impyiko na stenting ntibyagaragaje itandukaniro hagati y'uburyo bubiri bw'ubuvuzi mu kugabanya umuvuduko w'amaraso uri hejuru no kunoza imikorere y'impyiko ku bantu bafite stenosis y'imitsi y'impyiko yo hagati. Uburyo bwo gufungura imiyoboro y'amaraso bugomba gufatwaho ku bantu badakora neza ku miti gusa, abadashobora kwihanganira imiti, bakunze kubika amazi kandi bafite gucika intege kw'umutima birengagije ubuvuzi. Uburyo bwo kuvura stenosis y'imitsi y'impyiko bushobora kuba burimo: Renal angioplasty na stenting. Muri ubu buryo, abaganga bagura imitsi y'impyiko yagabanutse kandi bashyiramo igikoresho (stent) mu mubiri wawe w'amaraso gifata inkuta z'umubiri w'amaraso zifunguye kandi zemerera amaraso kugenda neza. Ubuvuzi bwo guhuza imitsi y'impyiko. Mu gihe cy'ubuvuzi bwo guhuza, abaganga bahuza imitsi y'amaraso ishinzwe gusimbuza imitsi y'impyiko kugira ngo bakore inzira nshya y'amaraso kugera ku mpyiko zawe. Rimwe na rimwe ibi bivuze guhuza imitsi y'impyiko n'umubiri uturuka ahandi, nko mu mwijima cyangwa mu nda. Ibi bikorwa bikorwa cyane niba angioplasty idakora, cyangwa iyo hakenewe ubuvuzi bundi bwongeyeho. Saba gahunda
