Patient then recalled left heart catheterization via femoral access 8-months before. CTA pelvis demonstrated 5x5cm right profundus femoris pseudoaneurysm. Within 2-weeks, patient underwent pseudoaneurysm thrombin injection with successful thrombosis. Femoral artery pseudoaneurysms are a potential complication of femorally accessed catheterization procedures. While uncommon, this can result in compressive mononeuropathy of femoral nerve. Thus, initial presentation with motor and/or sensory neurological deficits. This femoral mononeuropathy masqueraded as medial knee pain and treated with interventions based on mild radiographic findings despite atypical sensory abnormalities for knee OA. This case underscores the importance of thorough neurological examination, considering all relevant PMHx, and also reinforces use of sonography to further corroborate EMG diagnoses.
Conclusions: In patients who undergo cardiovascular procedures requiring femoral access, compressive femoral mononeuropathy secondary to vascular deformity should be considered in presence of sensation changes, lower motor neuron signs, and compensatory symptoms related to functional decline.
