Summary
Leg amputation, beyond traditional risk factors, contributes to abdominal aortic aneurysm development. Regular monitoring for aorto-iliac vessel changes is crucial for amputees to detect and manage potential complications.
Area of Science:
- Vascular Surgery
- Trauma Surgery
- Cardiovascular Research
Background:
- Above-knee amputation is associated with a higher incidence of infrarenal aortic aneurysms.
- Leg amputation may be a significant pathogenetic factor in abdominal aortic aneurysm (AAA) development, independent of arteriosclerotic risk factors.
Purpose of the Study:
- To investigate the late vascular sequelae following above-knee amputation.
- To determine the pathogenetic link between leg amputation and abdominal aortic aneurysm formation.
Main Methods:
- Retrospective study of 25 patients with above-knee amputation.
- Vascular assessment including flow volume measurement on the amputated side.
Main Results:
- One year post-amputation, significant adaptive narrowing of pelvic and leg arteries was observed.
- A 37% reduction in flow volume on the amputated side was registered.
- Unilateral flow reduction created an asymmetric flow pattern at the aortic bifurcation.
Conclusions:
- Altered hemodynamics post-amputation are a likely cause of late aorto-iliac vessel damage.
- Patients with unilateral leg amputation require regular follow-up for aorto-iliac vessel changes and AAA.
- Ipsilateral occlusive arterial disease and AAA should be considered secondary to leg amputation.
