Perforator Variability of the Anterolateral Thigh Flap Identified on Computed Tomographic Angiography: Anatomic and Clinical Implications

摘要

The anterolateral thigh (ALT) flap is a useful flap with minimal donor site morbidity. Preoperative computed tomographic angiography (CTA) for lower extremity reconstruction can determine vessel integrity and plan for recipient vascular targets. This study reviews lower extremity CTAs to further characterize ALT vascular anatomy and associated clinical implications thereof.
