Microsurgical adjuncts in salvage of the ischemic and diabetic lower extremity

Revascularization of distal occlusive disease in the diabetic has been markedly enhanced by microsurgical techniques. Extremely small, heavily calcified vessels are able to be reliably reconstructed using microsurgical techniques and high magnification. Additionally, revascularization followed by microsurgical free tissue transfer has proven to be a valuable alternative to amputation in patients with major soft-tissue loss, or bony or tendon lesions requiring soft-tissue reconstruction. Although metabolic risks are potentially high, we have experienced a very low morbidity and mortality with a thorough medical work-up and follow-through in conjunction with these major procedures. It is our expectation that judicious application of microsurgical techniques in treatment of the ischemic diabetic lower extremity will continue to improve the chances for long-term bipedal ambulation in this patient population.
