ʻO ka aorta ʻōpū (mai ka Greek aortê, ʻo ia hoʻi nā aʻa nui) kūlike i kahi ʻāpana o ke aorta, ka aʻa nui loa i loko o ke kino.

wahi. Aia ma waena o ka vertebra T12 a me ka Lumbar vertebra L4, ʻo ka aorta ʻōpū ka mea hope o ka aorta. (1) Hahai ia i ke aorta e iho mai ana, ka ʻāpana hope loa o ka aorta thoracic. Pau ka aorta ʻōpū ma ka hoʻokaʻawale ʻana i ʻelua mau lālā pili i ka ʻaoʻao hema a me ka ʻākau pono o nā aʻa ʻili, a ʻo kahi kolu o ka lālā waena, ka ʻāpana Sacal artery.

Nā lālā peripheral. Hāpai ka aorta ʻōpū i nā lālā he nui, ʻo ka parietal a me ka visceral (2):

• ʻO nā aʻa lalo phrenic i manaʻo ʻia no ka ʻaoʻao lalo o ka diaphragm
• ʻO ke kumu o Celiac e hoʻokaʻawale i ʻekolu mau lālā, ke aʻa hepatic maʻamau, ke aʻa splenic, a me ka aʻa ʻōpū hema. Hoʻonohonoho ʻia kēia mau lālā e vascularize i ke ake, ʻōpū, palu, a me kekahi ʻāpana o ka pancreas
• ʻO ke aʻa mesenteric kiʻekiʻe i hoʻohana ʻia no ka lako o ke koko i ka ʻōpū liʻiliʻi a nui
• ʻO nā aʻa adrenal e lawelawe i nā ʻōpū adrenal
• ʻO nā aʻa kīhāpai i manaʻo ʻia e hoʻolako i nā puʻupaʻa
• ʻO nā aʻa ovarian a me nā testicular e lawelawe i nā ovaries a me kahi ʻāpana o nā paipu uterine, a me nā testes
• ʻO ke aniani haʻahaʻa haʻahaʻa e lawelawe ana i kahi ʻāpana o ka ʻōpū nui
• ʻO nā aʻa lumbar i manaʻo ʻia no ka ʻaoʻao hope o ka paia ʻōpū
• ʻO ke aʻa medal Sacal e hoʻolako i ka coccyx a me ka sakum
• ʻO nā aʻa ʻiliac maʻamau i manaʻo ʻia e hoʻolako i nā mea o ka pelvis, ka ʻaoʻao haʻahaʻa o ka paia o ka ʻōpū, a me nā lālā o lalo

nenoaio i?. He mea nui ka aorta ʻōpū i ka vascularization o ke kino mahalo i kona mau lālā ʻokoʻa e hāʻawi ana i ka paia o ka ʻōpū a me nā mea maʻi visceral.

Pākuʻi uila. He paia elastis ka aorta e ʻae iā ia e hoʻopili i nā ʻokoʻa kaomi i kū i nā wā o ka hoʻoliʻiliʻi puʻuwai a me ka hoʻomaha.

ʻO ka aneurysm aortic aortic kona dilation, ke hana ʻia ke pili ʻole nā ​​paia o ke aorta. ʻO kēia mau aneurysms he spindle-shaped, ʻo ia hoʻi ka mea e hoʻopili ana i kahi ʻāpana nui o ka aorta, akā hiki nō hoʻi ke sacciform, kahi wahi o kahi aorta (3). Hiki ke hoʻopili ʻia ke kumu o kēia pathology i kahi hoʻololi o ka paia, i atherosclerosis a hiki i kekahi manawa ke ʻano infectious. I kekahi mau hihia, hiki i ka aneurysm aortic aortic ke paʻakikī e kuhikuhi me ka loaʻa ʻole o nā hōʻailona kikoʻī. ʻO kēia ka hihia me kahi aneurysm liʻiliʻi, ʻano e ke anawaena o ka aorta ʻōpū ma lalo o 4 cm. Eia nō naʻe, e ʻike ʻia kekahi ʻeha o ka ʻōpū a i ʻole ke kua i lalo. Ke holo nei, hiki i kahi aneurysm aortic aortic ke alakaʻi iā:

• ʻO ke kaohi ʻana o nā mea pili kokoke e like me ka ʻāpana o ka ʻōpū liʻiliʻi, ka ureter, ka vena cava inferior, a i ʻole kekahi mau aʻa.
• ʻO Thrombosis, ʻo ia hoʻi ka hoʻokumu ʻana o kahi ʻōpala, ma ke kiʻekiʻe o ka aneurysm;
• ʻO ka hoʻopau ākea ākea o nā lālā o lalo e pili ana i ke alo o kahi ālai e pale i ke koko mai ka holo maʻamau;
• he maʻi maʻi;
• kahi aneurysm ruptured e pili ana i ka haki o ka paia o ka aorta. Lilo ka makaʻu o kēlā rupture i mea nui ke ʻoi aku ke anawaena o ka aorta ʻōpū i 5 cm.
• kahi pilikia māwae e pili ana i ka "pre-rupture" a me ka hopena i ka ʻeha;

Lapaʻau ʻoki kino. Kaukaʻi ʻia i ke kahua o ka aneurysm a me ke ʻano o ka mea hoʻomanawanui, hana ʻia paha ke kaha ʻana ma ka aorta ʻōpū.

Mālama lāʻau. I ke ʻano o nā aneurysms liʻiliʻi, hoʻonoho ʻia ka mea maʻi ma lalo o ka mālama lāʻau akā ʻaʻole pono ia i kahi ʻoki.

Ninaninau kino. ʻO ka mea mua, hana ʻia kahi hoʻokolohua hoʻokolohua e nānā i ka ʻeha o ka ʻōpū a me / a i ʻole lumbar.

Ke nānā ʻana i nā kiʻi olakino e hōʻoia i kahi kuhi, hana ʻia paha kahi ultrasound ʻōpū. Hiki ke hoʻohui ʻia e kahi CT scan, MRI, angiography, a i ʻole kahi aortography.

Mai ka makahiki 2010, ua mālama ʻia nā kānana he nui e pale ai i ka aneurysms o ka aorta ʻōpū.
