OBJECTIVE: We evaluated the results of thoracic endovascular aneurysm repair (TEVAR) to determine what anatomic factors influenced the clinical outcomes.METHODS: Preoperative computed tomography (CT) angiograms of 65 patients who underwent TEVAR were analyzed using 3-dimensional imaging. The proximal and distal neck, thoracic aneurysm, and iliac arteries were measured for angulation, diameter, length, calcification, and tortuosity. Immediate technical success and clinical success were measured.RESULTS: Immediate technical success was achieved in 91% (59 of 65) of the patients analyzed. One patient died in the operating room during treatment of rupture. Clinical success was achieved in 83% (54 of 65) of patients at follow-up. Four patients had small endoleaks with no sac enlargement at follow-up. One patient was converted to open repair. Severe iliac calcification was found to be significant for deployment failure. The mean follow-up is 8 months (1-36 months).CONCLUSION: Increased iliac calcification and increased iliac tortuosity correlate with an inability to successfully deploy the device.
