Clinical snapshot Pseudoaneurysm Following Transfemoral Percutaneous Aortic Valve Replacement
An 86-year-old female patient developed acute swelling and bulging varicose veins on the right leg. The patient had undergone transfemoral percutaneous aortic valve replacement via a 9-F sheath 2 days previously due to high-grade aortic stenosis. Clinical examination revealed swelling of the right thigh as well as prominent varicose veins on the right great saphenous vein and its side branches. Ultrasound ruled out deep and superficial vein thrombosis; however, a pseudoaneurysm causing venous reflux in the saphenous vein was suspected. Subsequent computed tomography angiography (Figure a, b) confirmed a pseudoaneurysm of the right common femoral artery measuring 3.5 × 2.0 × 3.0 cm (Figure a, red arrow), which was compressing the right common femoral vein (Figure a, white arrow). Following surgical removal of the pseudoaneurysm, the patient was discharged 10 days postoperatively. Pseudoaneurysms occur in up to 7.9% of cases following transfemoral percutaneous aortic valve replacement. Predisposing factors include inadequate postinterventional compression, large sheath diameter, and multiple arterial punctures.
