OBJECTIVES: Postoperative spinal cord injury (SCI) is a devastating complication of surgical repair for thoracoabdominal aortic aneurysm or dissection (TAAD), despite the complex reconstruction of inter-costal or lumbar arteries involved in the surgery. As an alternative technique, endovascular thoracoabdominal aneurysm repair (EVTAR) with visceral artery reconstruction has been accepted as a treatment option for severe comorbid patients of TAAD, because there is a permissible frequency of SCI after EVTAR in spite of no reconstruction of inter-costal or lumbar arteries. We report the results of EVTAR at our hospital with a focus on spinal cord injury.
METHODS: We analyzed data from 54 consecutive patients with TAAD (mean age, 74 ± 9.6 years; 42 men) who underwent EVTAR at our hospital between February 2007 and February 2014. Three types of EVTAR technique were used: fenestrated and/or branched stent graft implantation in 39 patients, a hybrid technique (bypass grafts to visceral arteries and straight stent graft implantation) in 10 patients, and intentional coverage of the coeliac artery and straight stent graft implantation in 5 patients. In all patients, mean systemic blood pressure was maintained at ≥80 mmHg. Opioid use was avoided in the perioperative period.
RESULTS: According to the Crawford classification, the graft coverage extent was 9% (5/54) in type I, 11% (6/54) in type II, 39% (21/54) in type III, 22%(12/54) in type IV and 19% (10/54) in type V. In most patients (74%, 40/54), cerebrospinal fluid drainage was done intraoperatively and 1 day postoperatively. Hospital mortality was 5.6% (3/54). No patient developed SCI in the perioperative period. However, in the follow-up period 2 patients developed paraplegia as a consequence of shock caused by an aortic event.
CONCLUSIONS: With close attention to spinal cord protection, EVTAR may be associated with only a low incidence of SCI in the perioperative period. Therefore, EVTAR is expected to become a promising treatment option for appropriately selected patients with TAAD.
