Me ako tātou mō te 'uaua toto' matua o tō ngākau (Aorta Piki) me tōna hiranga.

I tēnei rā ka kōrero tātou mō tētahi wāhanga tino nui o tō tātou tinana, ā, ahakoa he ahua uaua, he tino māmā ki te mārama. Koia te (Aorta Piki) . He māmā noa iho, koinei te wāhanga tuatahi o te uaua toto matua, te (Aorta) , e tīmata ana i tō tātou ngākau, ka tohatoha i te toto ki te tinana katoa. He rite ki te wahi i whakatakotoria ki roto i te paipa matua e kawe mai ana i te wai mai i te tāke wai ki te whare. Nō reira, me titiro tātou he aha tēnei (Aorta Piki), he aha te mea ka pā ki a ia, he aha ngā momo mate ka pā mai, me pēhea te pupuri i tōna hauora.

He aha te (Aorta Piki)? He aha ngā hua o tēnei?

Whakaarohia he rite tō tātou tinana ki tētahi tāone nui. Me hiahia te wai ki ia whare, ki ia toa, ki ia wāhi o tēnei tāone. Waihoki, me hiahia te toto ma, ki tonu i te hāora ki ia pūtau o tō tātou tinana. Ko wai e pupuhi ana i tēnei toto puta noa i te tinana? Tō tātou ngākau. Ko te toto e pupuhihia ana e te ngākau ka haria puta noa i te tinana e te uaua toto matua, nui rawa (Aorta) , te aorta nui rānei.

He maha ngā wāhanga o tēnei (Aorta).

1. (Aorta e Piki Ana): Koinei te wāhanga e piki ake ana i tana putanga mai i te rūma matua e pupuhi ana i te toto e kiia nei ko te Ventricle Mauī kei te taha maui o te ngākau. Koinei tā tātou toa i tēnei rā.

2. (Aortic Arch): Kātahi ka piko ake tēnei ngongo pērā i te kakau o te rākau. Ka kiia ko (Aortic Arch).

3. (Aorta Heke): Kātahi ka heke iho tēnei ngongo, mā roto i te uma, mā roto i te puku. Ko te ingoa o taua wāhanga ko te (Aorta Heke).

Nō reira, ko te mahi matua o te (Aorta Piki) ko te tango i te toto whai hāora e pupuhihia ana e te ngākau ka tīmata te tohatoha ki te (Aortic Arch) ā, mai i reira ki te tinana katoa. Ina koa, ko ngā oko toto tino nui e rua e kiia nei ko ngā Coronary Arteries e tuku toto ana ki te ngākau ka tīmata mai i tēnei (Aorta Piki). Whakaarohia, me whai wai anō hoki te papu wai kia mahi ai, koinā te mahi.

Kei hea tēnei (Aorta Piki)? He aha tōna āhua?

Kei roto i tō tātou uma tēnei (Aorta Piki), ko te wheua nui kei waenganui o te uma, kei muri i te (Sternum) , ki te taha maui o te ngākau. E hono tika ana ki te (Ventricle Mauī) o te ngākau, ā, ka toro atu ki runga.

Mō te āhua, he rite te aorta katoa ki tētahi tokotoko iti kotahi. Ko te aorta piki te wāhanga poto rawa o te tokotoko e tīmata ana i te taha o te ngākau ka piki ake. Ko te āwhata aorta te wāhanga e piko ana pērā i te kakau o te tokotoko.

Ko te Aorta Piki he roa i waenga i te 5 me te 8 henimita (tata ki te 2 ki te 3 inihi) me te whānui tata ki te 3 ki te 4 henimita. Ka heke haere te whānui i a ia e heke ana i te uma.

He aha ngā wāhanga o te Aorta Piki? Me pēhea tōna hanganga?

E rua ngā wāhanga matua o te aorta katoa: te aorta thoracic me te aorta abdominal.Ka honoa ngā Aorta Piki (Ascending Aorta), ngā Aorta Āwhata (Aortic Arch), me ngā Aorta Heke (Descending Aorta) hei hanga i te Aorta Thoracic (Thoracic Aorta).

Ka tīmata te Aorta Piki i te taha o te Takirere Manawa Aorta, kei muri i te Ventricle Mauī. He rite tēnei Takirere Aorta ki te tatau. Ka tuwhera, ka kati hoki kia rere te toto mai i te Ventricle Mauī ki roto i te Aorta. Ka mutu te Aorta Piki i mua tata tonu i te Artery Brachiocephalic, te peka nui tuatahi e peka mai ana i te Āwhata Aorta.

E rua ngā wāhanga matua o te Aorta Piki:

1. (Pūtake Aorta): Koinei te pūtake o te (Aorta Piki), te wāhanga e tata ana ki te (Aortic Valve). Kei roto i tēnei he kōhao iti rite ki te porowhita e kiia nei ko (Aortic Sinuses) . Koinei te tīmatanga o te (Coronary Arteries) matau me te maui (ngā uaua e tuku toto ana ki te ngākau). Koinei anō te wāhi e tū ai te (Sinotubular Junction - STJ) . Ko te STJ te wāhi e huri ai te (Aorta Piki) hei ngongo noa.

2. Ngongo (Aorta Piki): Ka tīmata tēnei i muri i te STJ ka haere tonu ki runga ki te Āwhata Aorta. Kāore he peka atu o tētahi atu uaua toto mai i tēnei wāhanga.

Pērā i ngā wāhanga kē atu o te aorta, e toru ngā paparanga kiko o te aorta piki. Whakaarohia he rite ki te paipa, e toru ngā paparanga:

• (Tunica Intima): Koinei te paparanga o roto rawa. Ka rere te toto mā roto i tēnei.
• (Pāpāho): Koinei te paparanga o waenganui. He maha ngā muka pīwariwari o roto. Mā ēnei ka taea e te (Aorta) te whakawhāiti me te totoro i runga i te pēhanga toto. Heoi, i roto i te wā, ka ngoikore ēnei muka, ā, ka angiangi te pakitara.
• (Adventitia): Koinei te paparanga o waho rawa. Kei roto ngā uaua toto ririki e whāngai ana i te pakitara o te (Aorta).

He whakarāpopototanga noa iho, he 'paipa' tino nui, he kaha te Ascending Aorta e whiwhi tuatahi ana i te toto mai i te ngākau, kātahi ka tīmata ki te tuku puta noa i te tinana.

He aha ngā mate e pā ana ki te Aorta Piki?

Engari, ka taea hoki e tēnei wāhanga tino nui te whakawhanake i ngā momo mate. Kia tirohia tātou ko ēhea ngā mea matua:

• Ngā Aneurysm Aorta: He raruraru tino noa tēnei. Ko te aneurysm he ngoikore o te pakitara o te oko toto, ka pupuhi pērā i te poihau. Neke atu i te 50% o ngā aneurysm aorta i roto i te uma ka puta i roto i te aorta piki. Ka puta pea i roto i te pakiaka aorta, i te aorta piki tubular rānei. He āhuatanga morearea ngā aneurysm aorta. Nā te mea ka taea e te aneurysm te haehae i ngā paparanga o te oko toto – he āhuatanga e kiia nei ko te dissection aortic . Ki te pakaru katoa, ka puta he toto nui i roto i te tinana. He āhuatanga ohorere tēnei.

• (Te Stenosis o te Takirere Aorta):Ahakoa ehara te Aorta i te wāhanga o te Aorta Piki, e piri ana ki te pakitara o roto o te Aorta Piki. Ko te Aortic Stenosis he whaiti o te Aorta Piki i waenganui i te Pūtake Aorta me te Ventricle Mauī. Mā tēnei ka kaha ake te mahi a te ngākau ki te pupuhi toto ki roto i te Aorta. Ka taea e tēnei te whakanui ake i te uaua o te ngākau.

• (Te Regurgitation o te Aorta): Ka puta tēnei ina kore te (Aortic Valve) e kati tika. Kātahi, kaua e haere whakamua ki roto i te (Aorta), ka turuturu te toto ki roto i te (Left Ventricle). Mā tēnei ka nui ake te toto e pupuhihia ana e te ngākau i te mea noa. I roto i te wā, ka ngoikore te ngākau. Ka puta anō hoki te (Aortic Valve Regurgitation) nā te whānui haere o te (Ascending Aorta).

• Takirere Aorta Bicuspid (BAV): Ka whānau mai ētahi tāngata me ngā rau e rua i roto i tō rātou takirere aorta, kaua e toru. Ko te hunga whai takirere pēnei he nui ake te mōrearea ki te whakawhanake i ngā aneurysms aorta piki. He maha ngā wā ka taea e te BAV te whakapōrearea i te aorta, te ruaki o te aorta, ngā mea e rua rānei.

• Ngā Mate Hononga-a-Tinana: Ko te hunga whai mate pēnei i te (Marfan Syndrome) , te (Loeys-Dietz Syndrome) , me te (Ehlers-Danlos Syndrome) ka pāngia e ngā raruraru pēnei i te (Aneurysms) nā te mea ka ngoikore te pakitara o te (Aorta).

• Ngā Mate Mumura: Ka taea hoki e ngā āhuatanga pēnei i te Giant Cell Arteritis me ngā Penetrating Atherosclerotic Ulcers te kino i te pakitara o te aorta.

Ahakoa te āhua whakamataku o ēnei tohu, ka taea te whakahaere mēnā ka kitea wawetia, ā, ka rongoatia tika .

Me pēhea te pupuri i te hauora o taku Aorta Piki?

Ko ngā mea e mahia ana e koe hei pupuri i te hauora o tō ngākau me tō pūnaha tohanga toto he pai anō hoki mō te hauora o te Ascending Aorta.

• Kai i tētahi kai hauora, taurite: Kai i ngā kai he iti te konutai (tote), te cholesterol, me te ngako kukū. Kai atu i ngā hua rākau, huawhenua, witi katoa, me te muka.
• Whakakorikori tinana i ngā wā katoa: Me mahi tetahi mea pēnei i te hikoi, te oma, te kaukau rānei mō te 30 meneti pea i te rā. Ka whakapakari i te ngākau, ka whakahaere hoki i te toto toto.
• Kati rawa te kai hikareti me ngā hua tupeka: He hoariri nui te kai hikareti mō ngā uaua toto. Ka ngoikore te pakitara o te aorta, ā, ka piki ake te tūponotanga o ngā aneurysms.
• Whakaitihia, kati rānei te inu waipiro: Ka taea hoki e te inu waipiro nui te whakanui ake i te toto toto me te kino ki te ngākau me ngā oko toto.
• Me tirotiro hauora auau: He mea tino nui kia tirohia koe i ia wā e ai ki ngā tohutohu a tō tākuta, inā koa mēnā he raruraru tōu pēnei i te toto toto tiketike, te cholesterol, te mate huka, mēnā rānei kua pāngia tētahi o tō whānau e ngā raruraru aorta.

Āhea ahau me toro atu ki te tākuta?

Mena kua tāpaetia koe kei te mate koe i te Ascending Aortic Syndrome, i tētahi atu mate rānei o te ngākau, me toro atu ki tō tākuta tonu mēnā ka puta he tohu hou, mēnā rānei ka kino haere ō tohu o nāianei.

Waihoki, ki te pāngia koe e tētahi, e ētahi rānei o ngā tohu e whai ake nei, he tohu pea tēnei nō te pakaru o te aneurysm, ā, me rapu tonu koe i te awhina hauora ohorere:

• Te whanoke, te hemo rānei (te hemonga).
• Te tere o te manawa o te ngakau.
• Te mamae nui i te uma, i te tuara rānei o runga.
• Te uaua ki te manawa.

Kaua e warewarehia ēnei tohu. Mā te whiwhi maimoatanga wawe ka ora ai te tangata.
