Aorta abdominal (nke sitere na Greek aortê, nke pụtara nnukwu akwara) kwekọrọ na akụkụ nke aorta, akwara kachasị na ahụ.

ọnọdụ. N'ịbụ nke dị n'etiti vertebra thoracic T12 na lumbar vertebra L4, abdominal aorta bụ akụkụ ikpeazụ nke aorta. (1) Ọ na-esote aorta na-agbada, akụkụ ikpeazụ nke aorta thoracic. Aorta abdominal na-agwụ site n'ikewa n'ime alaka abụọ dị n'akụkụ nke mejupụtara akwara iliac nkịtị na aka ekpe na aka nri, yana alaka nke etiti nke atọ, akwara sacral median.

Ala dị n'akụkụ. Aorta afọ na-ebuli ọtụtụ alaka, ọkachasị parietal na visceral (2):

• Obere akwara phrenic dị ala nke ezubere maka okpuru diaphragm
• Ogwe Celiac nke kewara n'ime alaka atọ, akwara imeju na-ahụkarị, akwara splenic, na akwara afọ afọ ekpe. A na-ezube alaka ndị a iji mee ka imeju, afọ, splin, na akụkụ nke pancreas
• Ọbara mesenteric dị elu nke a na-eji enye ọbara na obere eriri afọ na nnukwu
• Akwara adrenal na-arụ ọrụ nke gland adrenal
• Akwara akwara nke e bu n'obi na-ebunye akụrụ
• Ovarian na testicular arteries nke na-eje ozi n'otu n'otu na-eje ozi ovaries nakwa dị ka akụkụ nke uterine tubes, na testes.
• Akwara mesenteric dị ala nke na-eje ozi akụkụ nke nnukwu eriri afọ
• Ọkpụkpụ Lumbar bụ nke ezubere maka akụkụ azụ nke mgbidi abdominal
• Median sacral artery nke na-enye coccyx na sacrum
• Akwara akwara ndị a na-ahụkarị bụ nke a na-ezube inye akụkụ ahụ nke pelvis, akụkụ ala nke mgbidi afọ, yana akụkụ nke ala.

Irrigation. Aorta abdominal na-ekere òkè dị ukwuu na vaskụla ahụ nke anụ ahụ ekele maka alaka ya dị iche iche na-enye mgbidi afọ na akụkụ visceral.

Mgbidi elasticity. Aorta nwere mgbidi na-agbanwe agbanwe nke na-enye ya ohere ime mgbanwe dị iche iche nrụgide na-ebilite n'oge oge nke obi obi na izu ike.

Aneurysm nke abdominal aortic aneurysm bụ mgbasa ya, na-eme mgbe mgbidi nke aorta adịkwaghị. Aneurysms ndị a na-enwekarị ụdị spindle, ya bụ na-emetụta akụkụ bụ isi nke aorta, mana nwekwara ike ịbụ sacciform, nke a na-edepụta ya na akụkụ nke aorta (3). Ihe kpatara pathology a nwere ike jikọta ya na ngbanwe nke mgbidi ahụ, na atherosclerosis na mgbe ụfọdụ ọ nwere ike ibute ọrịa. N'ọnọdụ ụfọdụ, ụbụrụ aortic aneurysm nke afọ nwere ike isi ike ịchọpụta na enweghị akara ngosi. Nke a bụ nke kachasị na obere aneurysm, nke ejiri dayameta nke aorta abdominal na-erughị 4 cm. Ka o sina dị, enwere ike inwe mmetụta mgbu afọ ma ọ bụ ala azụ. Ka ọ na-aga n'ihu, aneurysm nke abdominal aortic nwere ike iduga:

• Mkpakọ nke akụkụ ndị agbata obi dị ka akụkụ nke eriri afọ nta, ureter, vena cava dị ala, ma ọ bụ ọbụna ụfọdụ irighiri akwara;
• Thrombosis, ya bụ, nguzobe nke clot, na ọkwa nke aneurysm;
• Mkpochapụ akwara dị ukwuu nke akụkụ ụkwụ dị ala kwekọrọ na ọnụnọ nke ihe mgbochi na-egbochi ọbara ịgbasa nke ọma;
• ọrịa;
• aneurysm gbawara agbawa kwekọrọ na mgbawa nke mgbidi nke aorta. Ihe ize ndụ nke mgbawa dị otú ahụ na-aghọ ihe dị ịrịba ama mgbe dayameta nke aorta abdominal karịrị 5 cm.
• nsogbu nke fissure kwekọrọ na "tupu-rupture" na-akpata mgbu;

Ọgwụgwọ ịwa ahụ. Dabere na ọkwa nke aneurysm na ọnọdụ onye ọrịa, enwere ike ịwa ahụ na aorta abdominal.

Nlekọta ahụike. N'ihe gbasara obere aneurysms, a na-edobe onye ọrịa n'okpuru nlekọta ahụike mana ọ chọghị ịwa ahụ.

Nyocha anụ ahụ. Nke mbụ, a na-eme nyocha ụlọ ọgwụ iji chọpụta ihe mgbu abdominal na / ma ọ bụ lumbar.

Nyocha onyonyo ahụike Iji kwado nchoputa, enwere ike ime ultrasound nke afọ. Enwere ike ịgbakwunye ya site na nyocha CT, MRI, angiography, ma ọ bụ ọbụna aortography.

Kemgbe 2010, a na-eme ọtụtụ nyocha iji gbochie aneurysms nke abdominal aorta.
