New Techniques in Iatrogenic Coronary Artery Perforation Management Including Umbrella Technique, Case Report

Abstract

This case report presents a patient with iatrogenic coronary artery perforation during coronary angioplasty, complicated with a life-threatening cardiac tamponade. Tamponade decompression was achieved via timely pericardiocentesis with direct autotransfusion. The coronary artery perforation itself was initially closed by using the umbrella technique, which involves distal vessel occlusion with angioplasty balloon fragments. To control further blood extravasation into the pericardial sac, the perforation site was injected with thrombin, ensuring the leak closure. If performed with caution, these relatively rarely used, management techniques are effective in dealing with percutaneous coronary intervention complications.
