E aʻo kākou e pili ana i ka 'Descending Aorta' i loko o kou kino.

Ua noʻonoʻo paha ʻoe pehea e holo ai ke koko ma o ko kākou kino? Aia kekahi kīʻaha koko nui e lawe ana i ke koko i piha i ka oxygen mai ko kākou puʻuwai a i ko kākou kino holoʻokoʻa. Ua kapa ʻia ʻo ia ʻo ka aorta. I kēia lā, e kamaʻilio kākou e pili ana i kahi ʻāpana koʻikoʻi o kēia aorta, ʻo ia hoʻi ka aorta iho. Ua like ia me ka paipu wai nui loa i loko o ko kākou kino!

ʻO kēia 'descending aorta' hoʻokahi a ʻelua paha?

ʻOiaʻiʻo, ʻo kēia 'aorta iho' he kīʻaha koko lōʻihi hoʻokahi. Akā, e like me ka hoʻololi ʻana o ka inoa o ke alanui hoʻokahi mai ke kūlanakauhale a i ke kūlanakauhale, ua kapa ʻia kēia kīʻaha koko ma nā inoa like ʻole i kona hele ʻana ma nā ʻāpana like ʻole o ke kino. E noʻonoʻo, i ka wā e iho mai ai kēia aorta ma kou umauma, kapa mākou iā ia ʻo ' Descending Thoracic Aorta '. ʻO 'Thoracic' kahi huaʻōlelo a nā kauka e hoʻohana ai no nā mea e pili ana i ka umauma. A laila, i ka wā e hele ai kēia aorta ma kou diaphragm, e loli hou kona inoa. ʻO ka ʻāpana ma lalo o ka diaphragm ua kapa ʻia ʻo ' Descending Abdominal Aorta '. ʻO kēia ka mea e hele ana mai luna o kou ʻōpū a hoʻopau kokoke i kou piko.

No laila, he mea like anei ka 'Thoracic Aorta' a me ka 'Descending Aorta'?

ʻAʻole, ʻaʻole like lāua. Ke ʻōlelo mākou 'thoracic aorta', ʻo ia hoʻi ka ʻāpana holoʻokoʻa o ka aorta e holo ana ma kou umauma. He nui kona mau ʻāpana:

• Aʻa Aortic: ʻO kēia ka ʻāpana e pili ana i ka puʻuwai.
• Aorta piʻi: ʻO kēia ka ʻāpana e piʻi i luna mai ka puʻuwai.
• ʻAortic arch: ʻO kēia ka ʻāpana e hāʻawi i ka aorta i kona ʻano piʻo, e like me ke koʻokoʻo.
• ʻAorta thoracic iho: ʻO kēia ka ʻāpana o ka 'aorta iho' a mākou e kamaʻilio nei, aia i loko o ka umauma.

A laila, ʻo ka 'descending aorta' ka ʻāpana e hoʻolōʻihi ana i lalo ma hope o ke aortic arch. Hele ia ma waena o ka umauma (descending thoracic aorta) a me ka ʻōpū (descending abdominal aorta). I ka ʻōlelo maʻalahi, ʻaʻole like ka 'thoracic aorta' a me ka 'descending aorta'. Eia nō naʻe, aia kekahi ʻāpana o ka 'descending aorta' i loko o ka 'thoracic aorta'. Ua maopopo iā ʻoe?

He aha ka ʻokoʻa ma waena o ka 'Aorta Piʻi' a me ka 'Aorta Descending'?

He mea maʻalahi loa kēia. ʻO kāu 'Aorta Piʻi' ka ʻāpana e piʻo ana i luna mai kou puʻuwai a i ke aortic arch. Aia wale nō ia ma kou umauma. Eia naʻe, hoʻomaka ka 'Aorta Descending' ma kēlā ʻaoʻao o ke aortic arch, e piʻo ana i lalo. Holo ia mai kou umauma a hiki i lalo i kou ʻōpū.

He aha ka hana a kēia 'aorta iho'? No ke aha he mea nui loa ia?

ʻOiaʻiʻo, ʻo ka 'Descending Aorta' he kīʻaha koko ia e kuleana nui no ka hoʻolako ʻana i ko mākou kino me ke koko maʻemaʻe a me ka oxygen. E like me ke alaloa, ʻo ia ke aʻa nui e lawe ana i ke koko ma kou umauma a me kou ʻōpū. Mai kēia mai e lālā ai nā aʻa liʻiliʻi he nui, e hoʻolako ana i ke koko i kāu mau ʻōkana a me nā ʻiʻo like ʻole. E nānā i ka nui o nā mea a kēia 'descending aorta' a me kona mau lālā e hoʻolako ai i ke koko:

• I nā paia o kou umauma
• ʻO ka ʻōnaehana hoʻoheheʻe (ʻo ia hoʻi, kou esophagus , ʻōpū , nā ʻōpū liʻiliʻi a me nā ʻōpū nui)
• No nā puʻupaʻa
• No nā wāwae
• Nā kikowaena lymph
• I nā ʻōpū hānau (ʻo ia hoʻi nā testicles i nā kāne a me nā ovaries i nā wahine)
• I ka ʻōnaehana hanu
• ʻO ke kaula iwi kuamoʻo
• I ka ʻōnaehana mimi

E noʻonoʻo i ka nui o nā mea e hiki ke hoʻopilikia ʻia inā ʻaʻole hana pono kēia kīʻaha koko hoʻokahi!

ʻAuhea pololei kēia 'aʻa nui e iho ana'?

Hoʻomaka kou 'aorta iho' ma kou umauma, kahi e pau ai ke aortic arch. I ka pololei, aia ma hope pono o kahi e māhele ai kou aʻa subclavian hema mai ka aorta. Aia kēia ma kahi o ka pae o kou thoracic vertebra ʻehā (he iwi i loko o kou iwi kuamoʻo), ma waenakonu o kou iwi kuamoʻo. Mai laila mai, iho ia ma kou umauma, a laila ma kou diaphragm, a laila i loko o kou ʻōpū. Pau kēia 'aorta iho' ma kahi kokoke i kou pihi ʻōpū. Ma laila, māhele ia i ʻelua mau aʻa, ʻo nā aʻa iliac maʻamau ʻākau a me hema. Ua kapa nā kānaka ʻepekema i kēia mahele ʻo ka aortic bifurcation . ʻO ia no ka mea ua māhele ka aorta i ʻelua mau ala hou no ke koko e hele ai. A laila māhele kēia mau aʻa iliac i nā lālā ʻē aʻe e hoʻolako i ke koko i kou mau wāwae a me kou mau wāwae. Ua like kēia mahele me kahi Y i luna.

He aha nā lālā e lālā mai ana mai ke 'descending great artery'?

E like me kā mākou i ʻōlelo ai ma mua, he nui nā lālā o ka aorta iho e lawe ana i ke koko i nā ʻāpana like ʻole o ke kino. Ua like ia me ke kumu lāʻau me nā lālā liʻiliʻi. ʻO kekahi o nā lālā nui e lālā ana mai ka aorta iho o ka thoracic:

• Nā aʻa bronchial
• Nā aʻa esophageal
• Nā aʻa mediastinal
• Nā aʻa pericardial
• Nā aʻa phrenic kiʻekiʻe

Aia kekahi mau lālā nui e lālā ana mai ka aorta ʻōpū iho. Eia kekahi laʻana:

• Nā aʻa koko Celiac
• Nā aʻa Gonadal
• ʻO nā aʻa Iliac (ʻo kēia ka mea hope loa e māhele)
• Nā aʻa phrenic haʻahaʻa
• ʻO nā aʻa renal hema a me ka ʻākau (nā mea e hele i nā puʻupaʻa)
• Nā aʻa lumbar

ʻAʻole pono ʻoe e hoʻomanaʻo i kēia mau inoa a pau. ʻO ka mea nui e hoʻomaopopo he kōkua kēlā me kēia o kēia mau aʻa liʻiliʻi i ka hānai ʻana i nā ʻāpana like ʻole o ko kākou kino.

Pehea ke ʻano o kēia 'aorta iho'? Pehea ka nui?

Ua like ka aorta holoʻokoʻa me kahi lāʻau me kahi lima ʻōniʻoniʻo. ʻO ka aorta piʻi aʻe a me ke ānuenue aortic ka ʻāpana e like me ke ānuenue o ke lāʻau. ʻO ka aorta iho ka ʻāpana mua ma hope o ke ānuenue, kahi e iho pololei ana i lalo. No kona nui, hiki ke ʻokoʻa ke anawaena (ʻo ia hoʻi, ka laulā o ka ʻāpana kea) o ka aorta ma muli o kou makahiki, ka ʻili o ke kino, a me ke kāne. Akā eia nā waiwai awelika a nā mea noiʻi i ʻaelike ai:

• ʻO ka nui awelika o ka aorta descending thoracic he emi ma lalo o 1.6 kenimika no ka mika kuea o ka ʻili o ke kino.
• ʻO ka nui maʻamau o ka aorta descending abdominal: emi ma mua o 3 kenimika (ma kahi o 2 kenimika).

ʻO kēia ke aʻa nui loa i loko o ko mākou kino!

Pehea i hoʻokumu ʻia ai nā paia o ka 'descending aorta'?

Inā ʻoe e nānā i ka paia o kēia aorta, he ʻekolu papa o nā ʻiʻo. Ua like ia me ka paia o kahi paipu, akā ʻoi aku ka paʻakikī.

• ʻO Tunica intima: ʻO kēia ka papa o loko loa. Ke kahe nei kou koko ma o kēia. Hoʻomalu kēia papa i ke kaomi koko , pale i ke koko mai ka hoʻopili ʻana, a pale i nā mea ʻawahia mai ke komo ʻana i ke koko.
• Media: ʻO kēia ka papa waena. Loaʻa iā ia nā ʻiʻo liʻiliʻi e kōkua i ke koko e neʻe i hoʻokahi ʻaoʻao ma o ka ʻaelike ʻana. Loaʻa pū kekahi i nā olonā elastic. Hiki i kēia mau mea ke hoʻonāwaliwali i ka hala ʻana o ka manawa.
• ʻAvetenitia: ʻO kēia ka papa waho loa. Hāʻawi ia i ka aorta me ka ikaika a me ke ʻano. Hoʻopili pū ʻia ia i nā aʻalolo a me nā ʻiʻo e hoʻopuni ana.

He aha nā maʻi e hoʻopilikia ai i kēia 'descending aorta'?

ʻO ka mea pōʻino, hiki i kahi kīʻaha koko koʻikoʻi ke hoʻomohala i nā ʻano maʻi like ʻole. ʻO ka mea maʻamau o kēia mau kūlana he aneurysms aortic . ʻO ka aneurysm kahi wahi nāwaliwali i loko o ka paia o kahi aʻa, e hoʻoulu ai i ke aʻa e pehu a pehu. Aia kekahi mau ʻano aneurysms e hiki ke hoʻopilikia i ka aorta descending:

Nā ʻano o nā Aneurysms Aortic

• ʻO ka aneurysm aortic Thoracic (TAA): Hana ʻia kēia ma ka ʻaoʻao o luna o ka aorta e holo ana ma ka umauma. ʻO ka mea maʻamau, ʻo ia ke kumu o ke koko kiʻekiʻe a i ʻole ka trauma umauma. ʻO ka poʻe me kekahi mau maʻi pili, e like me ka Marfan syndrome, ʻoi aku ka nui o ka pilikia o ka loaʻa ʻana o kēia.
• ʻO ka aneurysm aortic ʻōpū (AAA): ʻO kēia ke ʻano maʻamau o ka aortic aneurysm. Loaʻa ia ma ka ʻāpana o ka aorta e holo ana ma ka ʻōpū. (AAA) hoʻopilikia pinepine i ka poʻe ma luna o 65 mau makahiki. ʻOi aku ka nui o ka ulu ʻana i nā kāne me ka mōʻaukala o ka hoʻohana ʻana i ka paka. ʻO Atherosclerosis, a i ʻole ka hōʻiliʻili ʻana o nā waihona momona i loko o nā paia o ke aʻa, ke kumu nui.
• ʻO ka aneurysm aortic Thoracoabdominal (TAAA): He aneurysm kēia e hoʻomaka ana mai ka umauma a i ka ʻōpū.

He mea nui: Inā he aneurysm kou ma ka aorta iho, e nānā kāu kauka iā ia no ka manawa lōʻihi. Inā nui loa ia, pono paha ʻoe i ka lāʻau lapaʻau e pale aku i nā pilikia e hoʻoweliweli ana i ke ola. Eia kekahi laʻana:

Nā kūlana weliweli e hiki ke kū mai ma muli o nā aneurysms

• ʻO ka haki ʻana o ka aneurysm: ʻO kēia ka wā e hana ʻia ai kahi lua ma ka paia (nā papa ʻekolu a pau) o ka aorta. Hiki i kēia lua ke hoʻoulu i ke kahe koko nui i loko o ke kino, kahi e hiki koke ai ke lilo i mea hoʻoweliweli i ke ola.
• ʻAno B aortic dissection: He haehae kēia i loko o ka papa o loko o ka 'descending aorta'. A laila hoʻopiha ke koko i ka hakahaka ma waena o nā papa o loko a me waena. Hiki i kēia ke kumu i ka pahū ʻana o ke aʻa a ʻoki i ke kahe koko i kekahi mau ʻōkana.

E hoʻomanaʻo, ʻo ka haki ʻana o ka aneurysm a i ʻole ka dissection aortic he pilikia ia e pono ai ke kōkua koke ʻana o ke kauka!

Nā kūlana ʻē aʻe e hiki ai

Ma waho aʻe o kēia mau aneurysms, aia kekahi mau kūlana ʻē aʻe e hiki ke hoʻopilikia i ka 'descending aorta':

• Atherosclerosis o ka aorta: Nā waihona momona ma loko o ka aorta.
• ʻO ka maʻi paʻa o Aortoiliac: Ke ālai nei nā waihona momona i ka ʻaoʻao haʻahaʻa o ka aorta (kokoke i ka bifurcation aortic) a me nā aʻa iliac.

He aha nā hōʻailona maʻamau o ka maʻi 'descending aorta'?

He mea nui loa kēia. ʻAʻole paha e hōʻike ka maʻi aortic iho i kekahi mau hōʻailona . ʻO ke ʻano kēia, ʻaʻole paha ʻoe e ʻike he hewa kekahi mea a hiki i ka loaʻa ʻana o kahi pilikia olakino.ʻO ia ke kumu e paipai ai nā kauka i nā nānā maʻamau. ʻO kēia ka manawa e hiki ai iā ʻoe ke ʻike i nā hōʻailona mua o ka hōʻeha puʻuwai. ʻOiai inā he aneurysm kou i loko o kou aorta descending, ʻaʻole paha ʻoe e loaʻa i kekahi mau hōʻailona a hiki i ka wā e pahū ai. Eia kekahi mau hōʻailona hōʻailona e ʻike ʻia ma mua o ka pahū ʻana:

• Ke manaʻo nei ua piha ʻoe ʻoiai ʻaʻole ʻoe i ʻai nui.
• ʻEha mau a mau ʻole ma ke kua, ka puʻupuʻu, ka ʻūhā, ka wāwae, a i ʻole ka ʻōpū.
• Ke manaʻo nei i ka puʻuwai o ka naʻau ma kahi ʻōpū.
• Paʻakikī i ka hanu ʻana a i ʻole ka wheezing.

E nānā! He mau pilikia kēia!

ʻO ka haki ʻana o ka aneurysm a i ʻole ka dissection aortic he pilikia olakino ia e pono ai ke kōkua koke ʻana o ke kauka . Inā loaʻa iā ʻoe kekahi o kēia mau hōʻailona , ​​e kelepona koke i ka 1990 (Sri Lanka's Suwaseriya Ambulance Service):

• ʻEha koke ka ʻōpū nui.
• He ʻeha koke, ʻoi, a koʻikoʻi hoʻi ma ka umauma a i ʻole ke kua o luna. Hiki ke like me ka haehae ʻana a i ʻole ke hou ʻana.
• Anuanu, hou pulu.
• Ka huikau.
• Ka poniuniu a i ʻole ka māʻule ʻana.
• Piʻi ka helu o ka puʻuwai.
• Ka luaʻi a me ka luaʻi.
• Paʻakikī ka hanu ʻana.
• Paʻakikī i ka ʻōlelo ʻana.
• Poho a pohihihi paha ka ʻike.
• Ka nāwaliwali a i ʻole ka maneʻo ma kekahi ʻaoʻao o ke kino.

Mai hoʻonele i kahi kekona i ka manawa e like me kēia!

Pehea e ʻike ai i nā maʻi o ka 'descending aorta'?

Hoʻomaopopo nā kauka i nā maʻi o ka aorta iho ma o nā hoʻokolohua kiʻi like ʻole. ʻO kēia nā ʻano hana e kiʻi i nā kiʻi o loko o ke kino. Eia kekahi mau laʻana:

• ʻO ka ultrasound ʻōpū
• ʻO ka CT Angiography (Computed tomography angiography - CTA)
• MRI (kiʻi hoʻohālikelike Magnetic - MRI)
• ʻO ke kaʻina hana echocardiogram transesophageal

Na kāu kauka e hoʻoholo i ka hoʻokolohua kūpono loa iā ʻoe.

He aha nā lāʻau lapaʻau no kēia mau kūlana?

E nānā kāu kauka i kou kūlana a e paipai i ka lāʻau lapaʻau inā pono. ʻO kekahi mau koho lapaʻau no kahi aneurysm ma ka aorta descending:

• ʻO ke ʻoki ʻana o ka aneurysm: He hana ʻoki kēia e wehe ai a hoʻoponopono paha i ka ʻāpana ʻōhū o ka aneurysm.
• Hoʻoponopono ʻana i ka aneurysm endovascular (EVAR):ʻO kēia ke komo ʻana i kahi mea like me ka stent i loko o ke aʻa ma o kahi ʻōmole liʻiliʻi (catheter) me ka ʻole o ka hana ʻana i kahi ʻoki nui, a me ka hoʻoikaika ʻana i ka wahi i puʻupuʻu. He ʻano hana hou kēia.
• Nā lāʻau lapaʻau e kāohi i ka hoʻonui ʻia ʻana o ka aneurysm: Hiki i kēia ke komo pū me nā lāʻau lapaʻau e hoʻohaʻahaʻa i ke koko a i ʻole ka cholesterol.

ʻO ka mea nui, ʻo ia ke hahai i nā ʻōlelo aʻoaʻo a ke kauka a hoʻokolohua i ka manawa.

Pehea e hiki ai iaʻu ke mālama i ke olakino o kaʻu 'descending aorta'?

ʻAe, he nīnau maikaʻi loa kēia. Aia kekahi mau mea hiki iā ʻoe ke hana e pale aku ai a hoʻopaneʻe paha i ka hoʻomaka ʻana o ka maʻi aortic. ʻO ke kī, ʻo ia ka hahai ʻana i kahi nohona olakino no ka puʻuwai. Eia kekahi mau ʻōlelo aʻoaʻo no ka hana ʻana pēlā:

• E hōʻemi i ka inu ʻona: ʻAʻole pono nā kāne e ʻoi aku ma mua o ʻelua mau anakahi waiʻona maʻamau i ka lā. ʻAʻole pono nā wahine e ʻoi aku ma mua o hoʻokahi anakahi waiʻona maʻamau i ka lā.
• E ʻai i ka meaʻai olakino a kaulike hoʻi, haʻahaʻa i ka sodium (paʻakai), cholesterol, a me nā momona saturated.
• E hoʻoikaika kino mau: E hoʻāʻo no ka liʻiliʻi he 150 mau minuke o ka hoʻoikaika kino ikaika waena i kēlā me kēia pule (e.g., hele wikiwiki, holo paikikala).
• E hoʻokele i ke kaumaha: Hiki i nā hana e like me ka yoga a me ka noʻonoʻo ʻana ke kōkua.
• E hoʻōki loa i ka puhipaka a me ka hoʻohana ʻana i nā huahana paka! He mea pono kēia e hana.

He aʻa koʻikoʻi loa kou aorta iho e kōkua ana i ka lawe ʻana i ke koko ma loko o kou kino. No laila, he mea nui loa ia e hana i nā mea āpau e hiki ai iā ʻoe ke mālama i ke olakino. ʻO ka ʻai maikaʻi, ka hoʻoikaika kino, a me ka noho ʻana mai ka paka e hiki ke kōkua i ka pale ʻana i ka maʻi aortic. Eia kekahi, mai poina e kiʻi i kahi nānā lapaʻau ma ka liʻiliʻi hoʻokahi manawa i ka makahiki.

No laila, he aha nā mea nui loa e pono ai kākou e hoʻomanaʻo mai kēia mau mea a pau?

ʻAe, i ka ʻōlelo maʻalahi, ʻo nā kumu nui āu e pono ai e hoʻomanaʻo mai nā mea a mākou i kamaʻilio ai:

• He ʻāpana koʻikoʻi ka 'Descending Aorta' o ke aʻa nui loa o ke kino, e lawe ana i ke koko waiwai i ka oxygen mai kou puʻuwai i lalo ma kou umauma a me kou ʻōpū.
• ʻO kēia ka mea e hoʻolako i ke koko i nā ʻōkana he nui i loko o kou umauma, ʻōpū, a me nā wāwae.
• Hiki i kēia aʻa ke hoʻomohala i nā maʻi e like me ka aneurysm a me ka atherosclerosis.
• I ka manawa pinepine, ʻaʻole hōʻike kēia mau maʻi i nā hōʻailona i nā pae mua, no laila he mea nui e hana i nā hoʻokolohua lapaʻau maʻamau.
• Inā ʻike ʻoe i nā hōʻailona e like me ka ʻeha koke a koʻikoʻi o ka umauma a i ʻole ka ʻōpū, ka paʻakikī o ka hanu ʻana, a i ʻole ka nāwaliwali, he pilikia paha ia. E ʻimi koke i ke kōkua lapaʻau.
• ʻO ka hahai ʻana i kahi nohona olakino (ʻai maikaʻi, hoʻoikaika kino, a me ka pale ʻana i ka puhipaka) e hele lōʻihi i ka mālama ʻana i ke olakino o kēia aʻa.

No laila, mai poina e mālama iki i kēia 'alanui' i loko o kou kino, ʻeā?
