This study shows that specific pressure measurements can predict the success of limb salvage surgery for advanced atherosclerosis. These findings aid in selecting patients for combined extra-anatomic bypass and profundoplasty procedures.

Area of Science:

Vascular Surgery
Cardiovascular Medicine
Surgical Outcomes

Background:

Advanced atherosclerosis in aortoiliac and femoropopliteal segments poses challenges for limb salvage.
Poor-risk patients often require complex surgical interventions.

Observation:

A combined procedure of extra-anatomic bypass with extended profundoplasty was employed for limb salvage.
Clinical and angiographic factors alone were insufficient for predicting surgical success.

Findings:

Successful limb salvage was achieved in poor-risk patients with advanced atherosclerosis.
Two key measurements predicted success: aortoiliac differential pressure (deltaP) and outflow bed response to papaverine.
Significant differences in deltaP (89.3 vs. 33.2 mmHg) and papaverine-induced outflow drop (36.3% vs. 11.3%) were observed between successful and failed cases.

Implications:

These simple hemodynamic measurements can guide patient selection for complex limb salvage procedures.
The findings facilitate a more accurate approach to treating ischemic limbs in high-risk populations.
Improved patient selection may lead to better outcomes in vascular reconstructive surgery.
