Problem: Peripheral arterial disease (PAD) and critical limb ischemia (CLI) impede lower extremity wound healing. The highest-risk patient populations have foot ulcers, ischemic disease, diabetes mellitus, and/or compromised kidney function. Optimal wound healing protocols require evaluation of both tissue and arterial perfusion. The most widely known test, ankle brachial index (ABI), has general but limited utility in foot ulcer patients. False negatives secondary to medial artery calcification are common and ABI alone is not considered predictive of wound healing. As many high-risk patients consider their medical home to be their primary care physician (PCP) not a limb preservation center (LPC), high-risk patients can be underserved secondary to inadequate awareness of the disease, limited diagnostics, and inefficient referral.
