CT findings following the cabrol composite graft procedure

Purpose: Insertion of a composite graft and reimplantation of the coronary arteries through an intermediate Dacron tube (Cabrol composite graft procedure) has been used to treat ascending aortic aneurysms and dissections. The CT findings after the Cabrol composite graft procedure have not been previously described. Method: Retrospective review of 12 postoperative CT and CT angiography (CTA) studies both in the immediate postoperative period as well as during long-term follow-up was conducted. Results: The Cabrol composite graft procedure produces typical CT findings consisting of a coronary conduit separate from the aortic graft. The presence of perigraft flow can be normal or abnormal depending on the time point of its occurrence and the extent of its hemodynamic consequences. Conclusion: Knowledge of the typical CT and CTA findings following a Cabrol composite graft procedure is essential for the correct interpretation of these studies.
