Omanyi ku nkulungo eno entono mu bwongo? (Circle of Willis) Ka twogere ku nsonga eno!

Wali owuliddeko ku 'Circle of Willis'? Mpozzi omusawo wo akubuulidde, oba okirabye mu lipoota y’abasawo emu. Mu butuufu kitundu kikulu nnyo ku bwongo bwaffe. Kiringa enkola y'obukuumi entono. Kale, ka twogere mu bufunze ku `(Circle of Willis)` eno kye ki ne kye kikola, okay?

‘Enkulungo ya Willis’ kye ki?

Okay, kale `(Circle of Willis)` kye ki? Mu ngeri ennyangu, nkola ya misuwa egisangibwa wansi ddala w’obwongo bwaffe, ku musingi. Kikolebwa ng’empeta, oba ekifaananyi eky’enjuyi ttaano (`(Pentagon)`) . Waliwo emisuwa emikulu ebiri egiwa obwongo bwaffe omusaayi omungi ogulimu omukka gwa oxygen era omuyonjo. Emu ye nkola ya `(Internal Carotid Artery)` , ate endala ye nkola ya `(Vertebral Artery)` . Kale kino `(Circle of Willis)` we wakwatagana emisuwa gino emikulu ebiri. Omusuwa gwa `(Internal Carotid Artery)` gusinga kuwa musaayi mu maaso g'obwongo, ate `(Vertebral Artery)` gusinga kuwa musaayi emabega w'obwongo.

Kino kiyitibwa ‘empeta ya Willis’ erinnya ly’omukugu mu by’omubiri Thomas Willis. Ye yatuyamba okuzuula bingi ku nsengeka eno. Era kiyitibwa amannya amalala, okugeza:

• ` (Enkulungo y'emisuwa gy'obwongo)` (Enkulungo y'emisuwa gy'obwongo)
• ` (Ensengekera ya Willis)` (Ensengekera ya Willis) .
• ` (Lupu ya Willis)` (Lupu ya Willis) .

Kino kiringa ‘fail-safe’ eri obwongo bwaffe, enkola y’obukuumi. Teebereza, singa emu ku misuwa gino emikulu ebbiri eyonoonese, okugeza, olw’omusuwa ogukutuse mu bwongo (Brain Aneurysm) oba okusannyalala, ekkubo eddala liyinza okugabira omusaayi ogumu eri ekitundu ekyo eky’obwongo ekyonoonese okuyita mu kino (Circle of Willis). Ekyo si kyewuunyisa?

Buli muntu (Circle of Willis) y'emu? Oba waliwo enjawulo?

Naye wuuno ekintu. Si buli muntu nti alina ``Circle of Willis'' etuukiridde. Okusinziira ku banoonyereza, abantu abatakka wansi wa kitundu kya bantu bagirina nga tegifudde ddala. Ekyo kitegeeza nti wayinza okubaawo enkyukakyuka entonotono mu nsengeka mu kyo. Ekyo bwe kibaawo, tukiyita ``Incomplete Circle of Willis'' .

Waliwo enkyukakyuka bbiri ezisinga okubeerawo naddala mu musuwa oguyitibwa Anterior Communicating Artery, ogusangibwa mu maaso ga Circle of Willis:

• Fenestration: Kino kiyinza okukosa ebitundu 21% ku bantu bonna. Fenestration kwe kuba nti omusuwa gweyawukana mu bibiri, ne gutambula olugendo olutono, oluvannyuma ne guddamu okwegatta. Kiba ng’oluguudo lwe lwawukana mu bibiri ate ne luddamu okwegatta.
• `(Okuddiŋŋana)` (Okuddiŋŋana):Kino kikosa abantu nga 18%. ``Okuddiŋŋana`` kitegeeza nti emisuwa ebiri egitandika okwawukana ne gikwatagana ne gikola omusuwa gumu.

Kati oyinza okuba ng’olowooza nti, ‘Watya singa Circle yange eya Willis nayo tetuukiridde?’. Tofaayo. Circle yo eya Willis ne bw’eba tetuukiridde, osobola okubeera n’obulamu obulungi nga tolina buzibu bwonna. Ebiseera ebisinga tekikosa nnyo nkola ya bwongo bwo. Kyokka, bw’ofuna obulwadde bw’emisuwa gy’obwongo, gamba ng’okusannyalala, olwo ebiva mu butatuukiridde obwo biyinza okuba eby’amaanyi katono. Kino si kintu kye tusobola okukyusa mu bugenderevu. Kino kisalibwawo engeri emisuwa gyaffe gye gikolebwamu mu kiseera ky’okuzaalibwa kw’embuto , kwe kugamba, nga tukyali mu lubuto.

Ekitali kijjuvu (Circle of Willis) kya bulijjo kitya?

Kale, kino `(Circle of Willis)` ekitali kijjuvu kya bulijjo kitya? Mu butuufu, abanoonyereza balowooza nti kitera nnyo. Naye kizibu okwogera ddala engeri gye kitera okubaawo. Kubanga, si buli muntu nti alina ekigezo kya `(Scan)` eky'obwongo. Nga tulina `(Scan)` bwetyo yokka obutonde bwa `(Circle of Willis)` eno bwe busobola okulabibwa ddala. Okusinziira ku kunoonyereza okw’enjawulo, kino `(Circle of Willis)` kiyinza obutaba kijjuvu mu wakati wa 50% ne 90% ku bantu abakulu . Ekyo kitegeeza nti abantu abasinga bagirina nga waliwo enjawulo entonotono.

Kiki ddala omulimu gwa Circle of Willis?

Kati ka twogere mu ngeri etegeerekeka obulungi katono ku kifo kino `(Circle of Willis)` nate. Kilowoozeeko nga `(Traffic Roundabout)` enguudo nnyingi gye zikwatagana.

Buli musuwa ogukola `(Circle of Willis)` gulinga ekkubo. Waliwo `(Highway)` enkulu bbiri, kwe kugamba, enguudo ebbiri ezisinga okutwala omusaayi. Ezo ze nkola ya `(Internal Carotid Artery)` eyayogeddwako emabegako, n'enkola ya `(Vertebral Artery)`. Enguudo endala entonotono mu `(Circle of Willis)` zeegatta wamu, ne zikola enzirugavu egatta ku nguudo ezo ennene ebbiri era ne zisobozesa omusaayi (i.e. entambula) okukulukuta.

Ekirungi ekiri mu kino kiri nti singa wabaawo ‘okuzibikira ekkubo’ oba ‘akabenje’ ak’amangu ku luguudo olwo olukulu (i.e., omusuwa omunene ogugaba omusaayi mu bwongo), oluguudo olulala lusobola okusindika omusaayi ogumu eri ekitundu ky’obwongo ekikoseddwa nga kiyita mu nkulungo eno. Mu ngeri ennyangu, okubeera ne `(Circle of Willis)` enzijuvu kitegeeza nti waliwo ekkubo ery'enjawulo (`(Detour Route)`) eriyinza okukozesebwa singa wabaawo okuzibikira oba ekizibu kyonna.

Bwoba olina `(Circle of Willis)` enzijuvu, esobola okukukuuma okuva ku mbeera ezimu ez'amaanyi. Naddala endwadde ezikosa emisuwa mu kino `(Circle of Willis)`. Okugeza nga:

• Amasavu agali munda mu misuwa (Atherosclerosis) .
• Okuvaamu omusaayi mu bwongo (e.g., olw’obuvune (Intracranial Hemorrhage)) .
• Obulwadde bw’emisuwa gy’omu lubuto / Obulwadde bw’emisuwa gy’omu lubuto
• Okuzimba emisuwa mu bwongo (Central Nervous System Vasculitis) .
• Omusuwa ogukutuse mu bwongo (Ruptured Brain Aneurysm) .
• Storoko
• Obulwadde bw’okulumwa omusaayi mu kiseera ekitono (TIA) oba mini-stroke

Naye, bw'oba olina ``Circle of Willis'' etali ntuufu, omulimu gw'obukuumi ogw'enkulungo eyo tegukola bulungi. Olwo, mu ndwadde ezikwatagana n’emisuwa gy’omusaayi mu bwongo nga zino, obulabe bw’ebikosa okuba obw’amaanyi buba bungi katono naddala mu mbeera y’okusannyalala.

Kino (Circle of Willis) kisangibwa wa?
