Towards Standardized, Safe, and Efficacious Screening Approaches to Patients with Lower Extremity Peripheral Arterial Disease in the Setting of Lower Extremity Arthroplasty

Introduction: Peripheral arterial disease (PAD) impedes the ability to recover from lower extremity arthroplasties (LEA) while simultaneously increasing risks of peri- and postoperative complications, morbidity, and mortality. Despite the known risks that PAD presents, there are currently no standards outlining how practitioners should screen patients prior to undergoing LEA. The purpose of this manuscript is to facilitate the improved diagnosis of PAD, leading to appropriate vascular surgery consultation prior to undergoing orthopedic surgeries. Recommendations for Preoperative Assessment: Screening begins with a succinct history and physical exam, looking for signs and symptoms of diminished vascular integrity. A heightened suspicion for PAD should prompt the immediate enactment of an ankle brachial index, or alternatively, a pressure volume recording or the skin perfusion pressure technique.
