Failed thrombin treatment due to patent collateral leakage after refractory guidewire-induced coronary artery perforation

摘要

Ellis class III coronary artery perforation is a rare but catastrophic complication associated with high mortality and poor outcome of percutaneous coronary intervention. We describe a case of coronary artery perforation caused by a stiff hydrophilic guidewire during percutaneous coronary intervention. Leakage from patent collaterals continued despite successful embolism of the perforated artery. Although he underwent cardiac surgery, the patient died due to the rupture of a left ventricular pseudoaneurysm.
