Hybrid Repair of Thoracoabdominal Aortic Aneurysms Is a Durable Option for High-Risk Patients in the Endovascular Era.
OBJECTIVE
To report our long-term experience in using the hybrid technique in complex thoracoabdominal aortic aneurysms (TAAAs).


METHODS
Between March 2005 and September 2013, 10 patients with TAAA underwent hybrid procedures with open renovisceral revascularization and thoracoabdominal aortic endografting. Patients were analyzed retrospectively.


RESULTS
Six men and 4 women with a mean age of 66 years (range 54-81 years) were treated electively during the study period. All 4 visceral vessels were revascularized in 8 patients, whereas 1 patient underwent 3-vessel revascularization and another 2-vessel revascularization. The primary technical success rate was 100%. Eight of the procedures were single staged, and the 2 most recent cases were performed in 2 stages. Perioperative and 30-day mortality was 0%. The mean follow-up was 55 months (4-133 months). None of the patients died due to aortic complications. Major complications included paraplegia (10%, n = 1) and bowel ischemia (n = 1). Postoperative cerebrospinal fluid (CSF) pressure and mean arterial pressure measurements were systematically monitored and corrected. The CSF drainage solved another 4 cases of paraparesis. Three patients required postoperative dialysis, but none of them required permanently. Postoperative spinal cord ischemia and renal complications accumulated in extensive TAAA cases. One renal graft was occluded 45 days after the initial procedure but was successfully treated with thrombolysis. One type I and 1 type III endoleak were noted and successfully treated with an additional stent graft. Two cases of type II endoleak were detected-one with a growing aneurysm sac was treated successfully and another showed no growth and further procedures were abandoned after 2 embolization attempts. In long-term follow-up, 90% of the aneurysms showed shrinkage by a mean of 23 mm (range 7-45 mm).


CONCLUSIONS
The results of hybrid repair on high-risk patients with complex TAAAs are encouraging, and this approach is a valuable alternative when branched and fenestrated endovascular techniques are not considered an option.
