Pseudoaneurysms and arteriovenous fistulas are rare complications associated with cardiac catheterization. A patient presented with atrial fibrillation after cardiac catheterization was performed one month prior. A sonogram was ordered due to leg swelling and an audible bruit in the right groin. The sonogram showed findings that were consistent with a pseudoaneurysm and arteriovenous fistula in this region. To obtain clinical correlation, an arteriogram was performed confirming these findings. A covered stent was implanted for treatment, which showed excellent results in a follow-up arteriogram and sonogram. Sonography served as an excellent modality in the evaluation and diagnosis in this case.
