title: Intravascular ultrasound in the management of acute coronary artery dissection: a case report.
abstract: Crossing total occlusions is frequently difficult. The guidewire may enter a false lumen, thereby preventing successful balloon dilatations. We present a case of an acute arterial dissection following attempted angioplasty of a totally occluded right coronary artery. With an intravascular ultrasound probe in the false lumen, we were able to visualize a second guidewire and direct its passage into the true arterial lumen. This allowed for successful balloon dilatation and stent deployment restoring vessel patency.
