Introduction

• Use of the trans radial approach for PCI has increased in coronary angiography and intervention cases.

• Arterial perforation is a rare complication during the trans radial approach, occurring less in less than 1% of cases.

PCI procedure

• CAG revealed restenosis of BMS in SVG.

• PCI was performed by transradial approach.

• We exchanged the 5Fr radial sheath for 6Fr.

• It was difficult to engage guide catheter to SVG. Thus we changed guide catheter 3 times. Finally, AL-2.0 was suitable. However, back up force of guide catheter was insufficient.

Procedure for artery embolization

• Despite compression of chest centered on bleeding site under fluoroscopic guidance, bleeding continued.

• Negative pressure with micro catheter was not effective, either.

• The decision was made to perform coil embolization.

Fat emblization

Take home message

• It is necessary to identify the tip of the guide wire during catheter exchange to avoid guide wire perforation of the side branch.

• Addition of fat embolization was effective when coil embolization was inadequate.
