Successful collapse vessel treatment with a syringe for thrombus-aspiration after the guidewire-induced coronary artery perforation.

Coronary artery perforation is a rare however potentially life-threatening complication of percutaneous coronary intervention that could cause cardiac tamponade. It requires emergent surgery unless an appropriate procedure is performed immediately. In distal coronary artery perforations with guidewires, several procedures were reported to be effective in refractory cases after prolonged balloon inflation and reversal of heparin by protamine sulfate to induce hemostasis. We describe a case of successful collapse distal coronary artery treatment with a syringe for thrombus-aspiration without materials for an embolization after guidewire-induced coronary artery perforation.
