Dural Arteriovenous Fistulas

Ibisigo bya arteriyo-venyeuse bya dural (dAVFs) ni uduhuza tudakozwe neza hagati y'imitsi n'imijyana. Bibaho mu gikoma gikomeye gipfunyika ubwonko cyangwa umugongo, kizwi nka dura mater. Inzira zidakozwe neza hagati y'imitsi n'imijyana bita arteriyo-venyeuse fistulas, bishobora gutera kuva mu bwonko cyangwa ibindi bimenyetso bikomeye.

Dural AVFs birare. Zikunda kugaragara hagati y'imyaka 50 na 60. Ntabwo zikunda kuba ari iz'umurage, ku buryo abana badafite amahirwe menshi yo kurwara dAVF niba umubyeyi wabo ayifite.

Nubwo bimwe mu bya dAVFs bituruka ku mpamvu zizwi, akenshi impamvu ntizirwa. Birizwa ko dAVFs zireba imijyana minini y'ubwonko zibaho iyo imwe mu mitsi y'amaraso y'ubwonko igabanuka cyangwa ikakingirwa. Imirongo y'amaraso ni inzira zinyuramo amaraso ava mu bwonko asubira mu mutima.

Ubuvuzi bwa dAVF busanzwe bukoresha uburyo bwo kuvura amaraso mu mitsi cyangwa stereotactic radiosurgery kugira ngo buhagarike amaraso ajya muri dAVF. Cyangwa bishobora kuba ngombwa kubaga kugira ngo bacikane cyangwa bakureho dAVF.

Abantu bamwe bafite ibibazo bya dural arteriovenous fistulas (dAVFs) bashobora kutabona ibimenyetso. Iyo ibimenyetso byabonetse, bishobora kugaragara nkibyoroheje cyangwa bikomeye. dAVF ikomeye ifite ibimenyetso bikomeye. Ibimenyetso bya dAVF bikomeye bishobora guterwa no kuva amaraso mu bwonko, bizwi nka intracerebral hemorrhage. Kuva amaraso mu bwonko kenshi biterwa n'ububabare bw'umutwe butunguranye. Bishobora kandi guteza ibindi bimenyetso hashingiwe ku gice n'ubunini bw'amaraso yavuyemo. Ibimenyetso bikomeye bishobora kandi guterwa no kubura ubushobozi bwo gukora imirimo y'ubwonko (NHNDs), bishobora kuba harimo indwara z'umwijima cyangwa impinduka mu bushobozi bwo gutekereza. Ibi bimenyetso bisanzwe bigenda bigaragara buhoro buhoro, mu minsi cyangwa mu byumweru. Ibimenyetso bisanzwe bijyanye n'agace k'ubwonko kagizweho ingaruka. Ibimenyetso bikomeye bishobora kuba birimo: Ububabare bw'umutwe butunguranye. Kugorana kogenda no kugwa. Indwara z'umwijima. Ibibazo byo kuvuga cyangwa imvugo. Kubabara mu maso. Demencia. Kugenda buhoro, gukakara no guhindagurika, bizwi nka parkinsonism. Kugorana guhuza ibintu. Kumva ubushyuhe cyangwa kubabara. Intege nke. Kubura inyota, bizwi nka apathy. Kunanirwa gukura. Ibimenyetso bijyanye no kwiyongera kw'umuvuduko, nko kubabara umutwe, isereri no kuruka. Ibindi bimenyetso bya dAVF bishobora kuba birimo ibibazo by'umva. Abantu bafite ibimenyetso byo kumva bashobora kumva ijwi rihindagurika mu gutwi ribaho uko umutima ukubita, bizwi nka pulsatile tinnitus. Ibimenyetso bishobora kandi kuba birimo ibibazo by'ububone, nka: Impinduka mu kubona. Ububyimba bw'ijisho. Kubyimba mu mubiri w'ijisho. Gupfa kw'imikaya iri mu jisho cyangwa hafi yaryo. Gake, demencia ishobora kubaho kubera kwiyongera kw'umuvuduko mu mitsi y'amaraso mu bwonko. Fata umwanya wo kubonana n'umuganga wawe niba ufite ibimenyetso bitari ibisanzwe cyangwa bikuguha impungenge. Shaka ubufasha bwa muganga ako kanya niba ufite indwara y'umwijima cyangwa ibimenyetso bigaragaza kuva amaraso mu bwonko, nka: Ububabare bw'umutwe butunguranye kandi bukomeye. Isreri. Kuruka. Intege nke cyangwa kubabara ku ruhande rumwe rw'umubiri. Kugorana kuvuga cyangwa kumva ibyavuzwe. Kubura ubushobozi bwo kubona. Kubona ibintu bibiri. Kugorana kubona umwanya.

Emera igitaramo n'umuganga wawe niba ufite ibimenyetso bitamenyerewe cyangwa bikuguha impungenge.

Shaka ubufasha bwa muganga ako kanya niba ufite ikibazo cy'igicuri cyangwa ibimenyetso bigaragaza kuva kw'amaraso mu bwonko, nka:

• Kubabara umutwe bikabije, bitunguranye.
• Kubeera mu nda.
• Kuruka.
• Kugira intege nke cyangwa ubugufi ku ruhande rumwe rw'umubiri.
• Kugira ikibazo cyo kuvuga cyangwa kumva.
• Kubura ubushobozi bwo kubona.
• Kubona ibintu bibiri.
• Kugira ikibazo cyo kubungabunga umubiri.

Ibihuha byinshi bya arteriovenous (dAVFs) nta mvano igaragara bifite. Ariko bimwe biterwa n'ubukomere bw'umutwe buturutse ku gisebe, kwandura, kubaga ubwonko mbere, ibibyimba by'amaraso mu mitsi minini cyangwa ibibyimba. Abahanga benshi batekereza ko dAVFs zibangikanye n'imitsi minini y'ubwonko ziterwa no gucika cyangwa gufunga imwe mu mitsi y'ubwonko. Imitsi y'ubwonko ni inzira ziri mu bwonko zinyuza amaraso ava mu bwonko asubira mu mutima.

Ibintu byongera ibyago byo kugira dural arteriovenous fistulas (dAVFs) birimo kuba ufite ubushake bwo kugira imikaya mu mitsi y'amaraso, bizwi nka vein thrombosis. Impinduka mu buryo imikaya itera ishobora kongera ibyago byo gufunga cyangwa kugabanya imitsi y'amaraso. Akenshi, dAVFs zibasira abantu bari hagati y'imyaka 50 na 60. Ariko zishobora kubaho no mu bantu bakiri bato, harimo n'abana. Ubushakashatsi bwerekanye ko imyenda idatera kanseri iboneka mu mpinga zizunguruka ubwonko n'umugongo ishobora kuba ifitanye isano na dAVFs.

Ubugenzuzi bwa MRI bukorerwa umuntu.

Niba ufite ibimenyetso bya dural arteriovenous fistula (dAVF), ushobora kuba ukeneye ibizamini byo kubona ishusho.

• MRI. Amafoto ya MRI ashobora kwerekana imiterere ya dAVF. MRI kandi ishobora kumenya amaraso make cyane. Iki kizamini gishobora kumenya ingaruka z'imiterere y'imitsi y'amaraso idasanzwe.
• Angiography. Angiography ya cerebrale ikoresha catheter, izwi kandi nka digital subtraction angiography, ni ikintu cyizewe cyane mu kuvura dAVF. Ni ingenzi mu kumenya:
• Umubare w'ibitotsi biriho n'aho biherereye.
• Imiterere y'imitsi ya carotid yo hanze n'amashami ari hagati yayo na dura. Imitsi ya carotid itanga amaraso mu bwonko no mu mutwe.
• Imiterere y'imitsi y'amaraso ya fistula.
• Niba indwara z'umutima na zo zihaba.
• Umuvuduko w'igipimo cyangwa ubupfu bwakozwe muri dural sinus.
• Niba imiyoboro y'amaraso ikozweho yagutse kandi ku rugero rungana iki.
• Umubare w'ibitotsi biriho n'aho biherereye.
• Imiterere y'imitsi ya carotid yo hanze n'amashami ari hagati yayo na dura. Imitsi ya carotid itanga amaraso mu bwonko no mu mutwe.
• Imiterere y'imitsi y'amaraso ya fistula.
• Niba indwara z'umutima na zo zihaba.
• Umuvuduko w'igipimo cyangwa ubupfu bwakozwe muri dural sinus.
• Niba imiyoboro y'amaraso ikozweho yagutse kandi ku rugero rungana iki.
