Superficial Femoral Artery Atherosclerosis Masquerading as Sciatica: Diagnosis and Conservative Management – A Case Report

Abstract

BACKGROUND: Often misdiagnosed as sciatica, vascular disorders such as peripheral arterial disease (PAD) can lead to a decreased quality of life. CASE PRESENTATION: The patient was a 44-year-old female referred to physical therapy with diagnosis of right-sided sciatica and L5-S1 degenerative disc disease, reporting right hip pain radiating into the thigh and foot, and worsening calf cramping. Based on inconsistent exam findings with lumbar spine imaging, patient comorbidities, and medication review, there was suspicion of PAD. The patient was referred to vascular surgery with recommendation of arterial ultrasound evaluation per American College of Radiology imaging guidelines. OUTCOME AND FOLLOW-UP: Arterial duplex revealed moderate arterial insufficiency with right distal superficial femoral artery occlusion. Patient underwent a 12-week supervised exercise program using the Gardner-Skinner Protocol for conservative management. DISCUSSION: Recognizing clinical presentation of arterial pathology, knowledge of imaging guidelines, and interdisciplinary care are essential for optimal management of PAD, particularly in cases with atypical risk factors.
