Kua rongo koe i te 'Circle of Willis'? Tērā pea kua kōrerotia e tō tākuta ki a koe, kua kite rānei koe i roto i tētahi pūrongo hauora. He wāhanga tino nui o tō tātou roro. He rite ki tētahi pūnaha haumarutanga iti. Nō reira, me kōrero poto tātou mō te āhua o tēnei '(Circle of Willis)' me āna mahi, āe?
He aha te 'Porowhita o Willis'?
Āe, he aha te `(Circle of Willis)`? He whakarāpopototanga noa iho, he pūnaha toto kei raro tonu i tō tātou roro, kei te pūtake. He rite tōna āhua ki te mowhiti, ki te āhua taha-rima rānei (`(Pentagon)`) . E rua ngā toto matua e tuku ana i te toto ma, he nui te hāora ki tō tātou roro. Ko tētahi ko te pūnaha `(Internal Carotid Artery)` , ā, ko tētahi ko te pūnaha `(Vertebral Artery)` . Nō reira, ko tēnei `(Circle of Willis)` te wāhi e hono ai ēnei toto matua e rua. Ko te `(Internal Carotid Artery)` te nuinga e tuku toto ana ki mua o te roro, ā, ko te `(Vertebral Artery)` te nuinga e tuku toto ana ki muri o te roro.
Ko te ingoa o tēnei ko te 'mowhiti o Willis' i muri i te tohunga hanganga tinana a Thomas Willis. Nāna mātou i āwhina ki te tūhura i ngā mea maha mō tēnei hanganga. E huaina ana hoki tēnei ki ētahi atu ingoa, hei tauira:
- `(Porowhita Arorangi Roro)` (Porowhita Arorangi Roro)
- ` (Willis Polygon)` (Willis Polygon)
- ` (Te Porowhita o Willis)` (Te Porowhita o Willis)
He rite tēnei ki tētahi 'haumaru-kore' mō tō tātou roro, he tikanga haumaru. Whakaarohia, mēnā ka pakaru tētahi o ēnei uaua toto matua e rua, hei tauira, nā te pakaru o te uaua toto i roto i te roro (Brain Aneurysm) nā te whiu rānei, ka taea e te ara kē te tuku toto ki taua wāhanga kua pakaru o te roro mā tēnei (Circle of Willis). He mea whakamiharo tēnā?
He rite tonu te āhua o te katoa (Circle of Willis)? He rerekētanga rānei?
Engari koinei te mea. Kāore i te katoa he "Porowhita o Willis" tino tika. E ai ki ngā kairangahau, he iti iho i te haurua o te taupori kei a rātou te "Porowhita o Willis" tino tika. Ko te tikanga tera pea he iti noa ngā huringa hanganga kei roto. Ina tupu tēnā, ka kiia e mātou ko te "Porowhita o Willis Kāore i Oti" .
E rua ngā huringa tino kitea, inā koa i roto i te uaua toto e kiia nei ko te Anterior Communicating Artery, kei mua o te Circle of Willis:
- Te Whakakī: Ka pā pea tēnei ki te 21% o te taupori whānui. Ko te whakakī he wā e wehea ai te uaua toto kia rua, ka haere mō te wā poto, kātahi ka hono anō. He rite ki te rori e wehea ana kia rua, kātahi ka hono anō.
- `(Te Tāruarua)` (Te Tāruarua):E pā ana tēnei ki te 18% o te tangata. Ko te tikanga o te "tāruarua" ko ngā uaua toto e rua e tīmata motuhake ana ka hono tahi hei hanga i te uaua toto kotahi.
Inaianei pea kei te whakaaro koe, 'Me pēhea mēnā kāore anō taku Porowhita o Willis kia oti?' Kaua e manukanuka. Ahakoa kāore anō tō Porowhita o Willis kia oti, ka taea e koe te noho ora me te kore raruraru. Kāore e pā nui ki te mahi a tō roro. Heoi, ki te pāngia koe e te mate roro, pērā i te whiu, ka nui ake te kino o taua hapa. Ehara tēnei i te mea ka taea e tātou te whakarerekē ā-tauira. Ka whakatauhia tēnei e te āhua o te hanganga o ō tātou oko toto i te wā o te kukune , arā, i a tātou kei roto tonu i te kōpū.
He pēhea te auau o te korenga o te mahi (Circle of Willis)?
Nā, he pēhea te noa o tēnei `(Porowhita o Willis)` kāore i oti? Inaa, e whakapono ana ngā kairangahau he tino noa. Engari he uaua ki te kī tika i te noa o te noa. Nā te mea, kāore e taea e te katoa te whai whakamātautau `(Matawai)` o te roro. Mā tēnei `(Matawai)` anake ka kitea tika te āhua o tēnei `(Porowhita o Willis)`. E ai ki ngā rangahau maha, tera pea kāore tēnei `(Porowhita o Willis)` i oti i waenga i te 50% me te 90% o ngā pakeke . Ko te tikanga he maha ngā tāngata e pāngia ana e tēnei mate, engari he iti noa ngā rerekētanga.
He aha rawa te mahi a te Porowhita o Willis?
Kia mārama ake tā tātou kōrero mō te mahi a tēnei `(Circle of Willis)`. Whakaarohia he `(Traffic Roundabout)` e huihui mai ai ngā rori maha.
He rite ia uaua toto e hanga ana i te `(Porowhita o Willis)` ki te rori. E rua ngā `(Huarahi Matua)` matua, arā, ko ngā rori e rua e kawe ana i te nuinga o te toto. Ko te pūnaha `(Internal Carotid Artery)` i whakahuatia ake nei, me te pūnaha `(Vertebral Artery)`. Ka honoa ngā rori iti kē atu o te `(Porowhita o Willis)`, ka hanga he porowhita e hono ana ki aua huarahi matua e rua, ā, ka taea te rere o te toto (arā, te waka).
Ko te painga o tēnei, mēnā ka puta he 'ārai' ohorere, he 'aituā' rānei i taua huarahi matua (arā, he uaua toto nui e tuku toto ana ki te roro), ka taea e te huarahi kē te tuku toto ki te wāhanga o te roro e pāngia ana mā tēnei porowhita. He māmā noa iho, ko te whai i tētahi `(Porowhita o Willis)` katoa he tikanga kei reira tētahi atu ara (`(Route Hurihuri)`) ka taea te whakamahi mēnā ka puta he ārai, he raruraru rānei.
Mena he `(Porowhita o Willis)` tōu, ka taea e ia te tiaki i a koe mai i ētahi mate kino. Ina koa ko ngā mate e pā ana ki ngā uaua toto i roto i tēnei `(Porowhita o Willis)`. Hei tauira:
- Ngā putunga ngako i roto i ngā oko toto (Atherosclerosis)
- Te toto ki roto i te roro (hei tauira, nā te whara (Te toto i roto i te angaanga))
- Te Mate o te Arota Carotid / Te Mate o te Arota Carotid
- Te mumura o ngā oko toto i roto i te roro (Te Vasculitis o te Pūnaha Nervous Waenga)
- He pakaru o te uaua toto i roto i te roro (Ruptured Brain Aneurysm)
- Whiu
- Te whakaekenga ischemic poto (TIA) te whiu poto rānei
Heoi, ki te mea kāore anō kia oti te "Porowhita o Willis", kāore te mahi tiaki o taua porowhita e mahi tika. Kātahi, i roto i ngā mate e pā ana ki ngā oko toto o te roro pēnei, ka paku teitei ake te mōrearea o ngā pānga kino, inā koa i te wā e pāngia ana e te whiu.

Tērā pea ka hiahia koe ki te mōhio kei hea tonu tēnei `(Porowhita o Willis)`. Kei te `(Turanga o tō Roro)`, i tētahi wāhi kei waho paku atu i te kiko roro (`(Wāhi Subarachnoid)`). Kei te taha tonu o te kakau o tō tātou `(Repe Pituitary)`, i raro noa iho i te `(Hypothalamus)`. Waihoki, he maha o ō tātou io angaanga (`(Nio Angaanga)`) e haere tata ana ki tēnei `(Porowhita o Willis)`.

Tērā pea kei te whakaaro koe, 'Āhea ahau ka rongo ai mō tēnei `(Circle of Willis)` mai i taku tākuta?' Āe, tera pea he maha ngā take mō tēnā:
- Mena he aneurysm roro tōu: Ko te Porowhita o Willis tētahi o ngā wāhi tino noa o te roro e puta ai ngā aneurysm. E ai ki ngā kairangahau tata ki te 85% o ngā aneurysm intracranial ka puta i te rohe e rere ana te toto i mua i te Porowhita o Willis.
- Mena ka pāngia koe e te whiu: Ka pā mai pea te whiu nā te aukati, te toto rānei i roto i te uaua toto i te Porowhita o Willis.
- Mena kei a koe te Mate Moyamoya: He tino onge tēnei mate roro. Ka puta mai ina ka whaiti haere, ka ārai rānei ngā uaua toto i roto i tō Porowhita o Willis, e tuku toto ana ki mua o tō roro.

- Mena ka pokangahia tō roro: I te wā e pokangahia ana tēnei wāhanga o tō roro – hei tauira, hei rongoā i te aneurysm, i te raruraru rānei o tō repe pituitary – he iti noa te tūponotanga ka pakaru tō Porowhita o Willis me ngā wāhanga nui e karapoti ana. Mena ka pakaru te Porowhita o Willis tonu, ka ārai pea i te rere o te toto ki te roro (Ischemia o te Roro) ka ngaro katoa rānei te rere o te toto (Infarction).
- Ki te mahi koe i tētahi matawai roro:Mena ka whai matawai roro koe, pērā i te angiogram roro, te MRI roro rānei (Magnetic Resonance Imaging), ka uru pea ki roto i tō pūrongo ngā taipitopito mō te Porowhita o Willis me tōna hanganga.

Ko ētahi tākuta me ngā puna hauora e kī ana i te `(Moyamoya Disease)` kua whakahuatia i mua ko `(Circle of Willis Syndrome)`. Ko tētahi atu ingoa mō `(Moyamoya Disease)` ko `(Spontaneous Occlusion of the Circle of Willis)`.
Me aha tātou kia ora tonu ai tēnei (Circle of Willis)?
Nā, me aha tātou hei pupuri i te hauora o tēnei "Porowhita o Willis" me ētahi atu uaua toto i roto i te roro? Ko te mea nui ko te whakahaere i ngā āhuatanga mōrearea mō te whakawhanake i te mate roro mena kei a koe ēnei āhuatanga. Ko ēnei āhuatanga mōrearea ko:

Ko te mea nui ko te noho i roto i te huarahi e ora ai ngā oko toto o te roro, e ārai ai hoki i ngā mate pēnei i te whiu. Ko te tikanga o tēnā ko te whakawhanake i ngā tikanga pai me te whakahaere i ngā āhuatanga mōrearea kua whakahuatia ake nei.
He tokomaha te hunga kāore pea i te rongo mō tō rātou `(Circle of Willis)`. Heoi, ki te mea he mate roro tōu, pērā i te `(Aneurysm),' kua whakahuatia pea e te tākuta.Ki te kī mai tō tākuta i tētahi kupu hauora kāore koe e mārama, kaua e wehi ki te tono whakamārama. He tika tōu ki te mōhio ki ngā mea e pā ana ki roto i tō tinana.
