Erosion of Common Femoral Artery 3 Years After Total Hip Arthroplasty in a Patient with Marfan Syndrome

Abstract

Case: A patient with congenital hip dysplasia and Marfan syndrome presented 3 years after total hip arthroplasty (THA) with acute ischemia of the left lower extremity secondary to popliteal artery embolism. Intravenous ultrasound revealed common femoral artery (CFA) dilation with an intraluminal thrombus. Open repair showed prosthetic erosion through the CFA despite proper implant positioning and lack of hardware failure. Conclusion: This is a rare complication of THA in a patient with impaired vascular integrity secondary to a connective tissue disorder. Similar patients may be at a higher risk for unusual vascular complications, and diagnosis may require atypical imaging modalities.
