본문내용
Occlusive aortic disease caused by atherosclerosis
: usually confined to the distal abdominal aorta below the renal arteries
The severity of the symptoms depends on the adequacy of collaterals
With sufficient collateral blood flow
: a complete occlusion of the abdominal aorta may occur without the development of ischemic symptoms.
Acute occlusion in the distal abdominal aorta is medical emergency because it threatens the viability of the lower extremities
It usually results from an occlusive embolus that almost always originates from the heart
Clinical manifestations
: severe rest pain, coolness, pallor of the lower extremities and the absence of distal pulses bilaterally
Diagnosis should be established rapidly by MRI, CT
Emergency thrombectomy or revascularization is indicated
It often affects the ascending aorta and aortic arch, causing obstruction of the aorta and its major arteries
Pulseless disease
: frequent occlusion of the large arteries originating from the aorta
The pathology
: panarteritis, characterized by mononuclear cells and occasionally giant cells, with intimal hyperplasia, medial and adventitial thickening
