E mōhio ana koe ki tēnei porowhita iti i roto i te roro? (Porowhita o Willis) Me kōrero tāua mō tēnei!

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.

Kei hea tēnei (Circle of Willis) e tū ana?

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).

• 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.
