Catheter-Induced Aortic Dissection After Invasive Coronary Angiography: Evaluation With MDCT

OBJECTIVE: The purpose of this study was to describe the MDCT findings of retrograde aortic extension of catheter-induced coronary artery dissection and the use of MDCT in follow-up of this complication. CONCLUSION: Coronary artery dissection with aortic extension can be a fatal although infrequent complication. The coronary artery entry point is usually stented in the catheterization laboratory. Thereafter, CT is the imaging modality of choice for immediate confirmation of the presence of residual iatrogenic aortic dissection and evaluation of its extent and later noninvasive follow-up.
