Pseudoaneurysm After Distal Transradial Coronary Intervention Successfully Managed by Prolonged Pneumatic Compression: Simple Solution for a Rare and Challenging Problem.

A 75-year-old woman with hypertension, hypothyroidism, and diabetes was referred to the catheterization laboratory due to non-ST segment elevation myocardial infarction. Urgent coronary angiography was uneventfully performed via right distal transradial access, despite lusoria subclavian artery. Left anterior descending artery was successfully treated by percutaneous coronary intervention with stenting. A TR band was left in situ for 60 minutes and completely removed after 2 hours, without bleeding. Proximal and distal radial pulses were palpable after hemostasis and at hospital discharge, 24 hours later, uneventfully. Six days after, she noticed subtle and rapidly progressive wrist, hand and fingers swelling, with pain, ecchymosis, and movement limitation.
