Value of Cone Beam CT in the endovascular repair of abdominal aortic aneurysms
G. Gemayel, Presenter: G. Gemayel (Meyrin)
We report a single center experience of using the cone beam CT at the end of endovascular aortic repair (EVAR) to detect and immediately correct any structural anomalies of the graft not visible of the standard completion angiography.
During the last 18 months, every patient treated by EVAR received a cone beam CT at the end of the procedure. Most exams were performed without contrast injection except for one case were the patency of visceral vessels was also assessed. Images were immediately studied while the patient was still on the operating table. Any endograft kink or compression were evaluated treated on the spot.
36 consecutive patients were treated by EVAR and assessed by cone beam CT. A graft kink or limb compression that were not visible of the completion angiography were detected in three patients . All were successfully treated by additional stenting in two patients and angioplasty alone in one. None of the three patients had a reintervention for the same problem on follow up.
Cone beam CT can detect structural anomalies in endografts following EVAR that are not visible on a standard angiography. It avoids bringing back the patient to the operating table when these same anomalies are detected on the post op control CT scan. It thus avoids any complication that might occur while waiting for the repair.
