Abstract

BACKGROUND:

Major vessels in the diabetic foot are often calcified and inadequate for use as recipient vessels. Thus, a supermicrosurgery technique using small branches or perforators from other collateral vessels with an adequate pulse may be an alternative method. This study evaluated outcome using the supermicrosurgery concept and the risk factors involved.

METHODS:

Ninety-five cases of diabetic foot reconstruction were reviewed; the average patient age was 57 years; average follow-up was 43.5 months. D├ębridement was performed according to the angiosome concept, and reconstruction was performed with perforator flaps using the supermicrosurgery approach. Correlation between total flap loss and 16 preoperative risk factors (age, sex, diabetes mellitus type, smoking, immunosuppression, flap size, hemoglobin A1c, ankle-brachial index, preoperative transcutaneous partial pressure of oxygen, C-reactive protein, computed tomographic angiography, amputation history, peripheral artery disease, American Society of Anesthesiologists physical status, osteomyelitis, and chronic renal failure) were analyzed.

RESULTS:

Of 95 cases, nine cases of total loss and 12 of minor complication were noted. Among the risk factors, the odds for failure after peripheral artery disease was 10.99 (p = 0.035), and that associated with a history of amputation was 9.44 (0.0006). Other factors had no correlation with flap loss, including cases with no or one major vessel. Flap survival rate was 90.5 percent, and the overall limb salvage rate was 93.7 percent.

CONCLUSIONS:

Despite the high risk of failure related to peripheral artery disease and history of amputation, the supermicrosurgery approach using a recipient vessel with good pulsation regardless of the source can achieve limb salvage. This approach extends the possibility for reconstruction in patients with severe ischemic diabetic foot.
