Ese wigeze utekereza ku buryo ubwonko bwacu buhambaye kandi bukozwe mu buryo butangaje? Kugira ngo ubwonko bukore neza, bukenera amaraso meza kandi akungahaye kuri ogisijeni buri gihe. Rero kugira ngo bukore iki gikorwa neza, ubwonko bufite uburyo butangaje bwo kwirinda. Ni nk'uruziga runini hagati mu mujyi, rugufasha gufata undi muhanda niba hari urujya n'uruza rw'imodoka. Uyu munsi turimo kuvuga kuri ubu buryo butangaje bwo kwirinda.
Uruziga rwa Willis ni iki?
Mu magambo make,
uruziga rwa Willis (CoW) ni
imiterere isa n'impeta igizwe n'imitsi y'amaraso
(imitsi) iri ku nsi y'ubwonko bwacu, ni ukuvuga hepfo. Ifite ishusho nk'iya pentagram. Iyi ni inzira ihuza imitsi ibiri y'ingenzi itanga amaraso mu bwonko bwacu. Tekereza ko hari imitsi ibiri y'ingenzi izana amaraso mu bwonko bwacu. 1.
Umutsi wa Carotid wo mu Mutwe: Iyi ni yo nzira itanga amaraso menshi imbere y'ubwonko. 2.
Umutsi wo mu Mugongo: Iyi ni yo nzira itanga amaraso inyuma y'ubwonko. Rero, iyi mitsi yombi y'ingenzi ihurira ku ruziga rwitwa uruziga rwa Willis. Kubera iyo mpamvu, iyo hari imbogamizi cyangwa kuziba mu mutsi umwe, amaraso ashobora koherezwa mu gace gakenewe binyuze mu wundi mutsi. Ibi ni nk'uburyo karemano 'butagira ingaruka mbi' ku mutekano w'ubwonko bwacu. Byitwa "Impeta ya Willis" mu rwego rwo guha icyubahiro umuhanga mu by'imiterere y'umubiri Thomas Willis, wavumbuye byinshi kuri iyi miterere itangaje.
Ese buri wese afite iyi mpeta?
Dore ikintu gitangaje. Nk’uko abashakashatsi babivuga, abantu bake cyane bafite
impeta yuzuye ya Willis . Ibyo bivuze ko abantu benshi bashobora kugira uduce duto, cyangwa inenge, muri iyi mpeta. Utu duce duto tuba tuvukana. Izi ni impinduka zisanzwe ziba iyo imitsi yacu y’amaraso ivutse mu nda. Iyi si indwara cyangwa inenge.
Kugira impeta ya Willis ituzuye ntibisobanura ko urwaye. Abantu benshi babaho ubuzima bwiza iyo impeta ya Willis ituzuye.
Ariko, dore ikibazo. Niba umuntu ufite ikibazo cy’ihungabana ry’amaraso mu bwonko kidahagije afite ikibazo kijyanye n’imitsi y’amaraso mu bwonko, nko
kurwara indwara yo mu bwonko , ingaruka zishobora kuba nyinshi kurushaho. Kubera ko iyo 'nzira yindi' cyangwa 'inzira yo kunyuramo' twavuzeho idakora neza. Iki si ikintu dushobora guhindura, ni uko imibiri yacu yubatswe.
Ni iki gisobanuro nyakuri cy'Impeta ya Willis?
Uburyo bwiza bwo kubisobanukirwa ni ukurushaho gusobanura urugero rw'uruziga rw'imodoka twavuze mbere. Tekereza uruziga runini nk'urwo ku Ngoro y'Umujyi ya Colombo. Ruhuza imihanda minini myinshi. Noneho tekereza ko hari impanuka ikomeye kuri imwe mu mihanda minini kandi umuhanda urafunze burundu. Bigenda bite se? Imodoka ziva mu yindi mihanda zishobora gukoresha uru ruziga, zinyura mu muhanda wafunze zikagera aho zijya. Impeta ya Willis ikora
ibi neza . Iyo umutsi munini w'amaraso ujyana amaraso mu bwonko ufunze cyangwa wangiritse, niba hari Impeta ya Willis yuzuye, amaraso aturuka ku rundi ruhande ashobora kunyura muri uru ruziga agatanga amaraso mu gice cy'ubwonko cyabuze amaraso. Ibi birinda kwangirika gukomeye mu bihe byinshi. Kugira Impeta ya Willis yuzuye bishobora kukurinda ingaruka mbi z'indwara zikurikira:
| Indwara | Uburinzi butangwa na Ring of Willis |
|---|
| Igisebe cy'imitsi | Nubwo umutsi w'amaraso wafungwa, amaraso anyura mu bundi buryo, bigabanura kwangirika k'ubwonko. |
| Aneurysm yo mu bwonko iraturika | Bifasha mu kubungabunga amaraso mu bice bikikije umuyoboro wangiritse. |
| Ibinure byinjira mu mitsi y'amaraso (atherosclerosis) | Uko umuyoboro w'amaraso ugenda ugabanuka buhoro buhoro, ni ko amaraso atembera mu yindi miyoboro y'amaraso yiyongera kugira ngo agere ku cyuho. |
| Indwara y'imitsi ya Carotid | Nubwo umutsi munini wo mu ijosi wafungwa, bifasha mu kubungabunga uburyo amaraso anyura mu bwonko. |
Ni amahirwe angahe muganga ashobora kukubwira kuri ibi?
Ubusanzwe, abantu benshi ntibazigera bamenya ko bafite impeta ya Willis kugeza igihe bazayisuzuma. Ariko, rimwe na rimwe, muganga wawe ashobora kubikubwira.
- Niba ufite aneurysm yo mu bwonko : Hafi 85% by'aneurysm yo mu bwonko ibera muri Ring of Willis.
- Niba ufite stroke : stroke ishobora guterwa no kuziba cyangwa kuva amaraso mu mitsi y'amaraso iri mu gice cya Willis.
- Niba ufite indwara ya Moyamoya: Iyi ni indwara idakunze kugaragara cyane ituma imiyoboro y'amaraso iri mu gice cya Willis igabanuka buhoro buhoro ikafunga.
- Niba bikenewe kubagwa mu gice cyo hasi cy'ubwonko: Urugero, mu gihe ubaga indwara ya aneurysm cyangwa ikibyimba cya pituitary gland, ni ngombwa cyane kwirinda kwangiza impeta ya Willis.
- Niba wakorewe isuzuma ry’ubwonko : Niba wakoze ikizamini cyihariye, nka MRI y’ubwonko cyangwa angiogram yo mu bwonko, raporo ishobora kuba irimo amakuru yerekeye imiterere ya Ring of Willis yawe.
Ni iki twakora kugira ngo impeta ya Willis ikomeze kuba nzima?
Nkuko twabiganiriyeho mbere, ntidushobora guhindura imiterere y'Impeta ya Willis. Ni ikintu kibaho igihe umuntu avuka. Ariko, hari byinshi dushobora gukora kugira ngo imiyoboro y'amaraso iri muri iyo mpeta ikomeze kuba myiza kandi idafite imiyoboro ifunganye. Muri make,
tugomba kugenzura ibintu bishobora kwangiza imiyoboro y'amaraso mu bwonko. Reka turebere hamwe ibyo bintu bishobora gutera ibyago. Kubigenzura si byiza gusa kuri Impeta ya Willis yawe, ahubwo no ku mubiri wawe wose, cyane cyane umutima wawe.
