Successful management of a distal vessel perforation through a single 8-French guide catheter: Combining balloon inflation for bleeding control with coil embolization.

Coronary perforation is an infrequent, but serious complication of percutaneous coronary intervention (PCI), and is more likely to occur with complex (such as chronic total occlusion) PCI and use of atheroablative devices. For main vessel perforations, the "dual catheter" technique is usually employed in which a balloon is delivered over the first guide catheter to stop bleeding, whereas the covered stent is delivered through a second guide catheter. This is required because the large profile of the currently commercially available covered stents precludes fitting within even an 8-French guide together with a balloon. However, coil embolization for distal artery wire perforation and collateral vessel perforation can be achieved through a microcatheter that can fit along with a balloon within an 8-French guide catheter, obviating the need for a second guide catheter. We describe a case in which a distal artery wire perforation was successfully treated using a single 8-French guide catheter.
