Development and treatment of two distinct pseudoaneurysms following transradial coronary catheterization in a patient with high bleeding risk: a case report

BACKGROUND: A pseudoaneurysm is a rare but serious complication after transradial coronary catheterization. Although different treatment modalities have been proposed to treat post-catheterization pseudoaneurysm, only limited data are available to guide the treatment approach. CASE PRESENTATION: We report a rare case of two distinct pseudoaneurysms complicating transradial percutaneous coronary intervention in a 75-year-old Hispanic woman being treated with dual antiplatelet agents for myocardial infarction and warfarin for atrial fibrillation. The pseudoaneurysms were diagnosed with ultrasound and were successfully treated with a series of Terumo Corporation (TR) band compressions. CONCLUSIONS: This case demonstrates the efficacy of compression therapy in managing post-catheterization radial artery pseudoaneurysm in patients with high bleeding risk.
