Aortic dissection, a complication during successful angioplasty of chronic total occlusion of the right coronary artery, was treated conservatively.

Aortic dissection is an uncommon but potentially lethal complication that can occur during the engagement of a guiding catheter. We report a case of a 59-year-old woman with acute aortic dissection due to percutaneous coronary intervention. This resulted in a retrograde extension of the dissection into the proximal part of the ascending aorta. With haemodynamic stability, we decided to treat the aortic dissection medically. As a result, a complete resolution of the aortic dissection was documented by coronary angiography and the follow-up computed tomography scan.
