Abstract:
OBJECTIVE:Thoracoabdominal aortic aneurysm is one of the most challenging aortic diseases. Open surgical repair remains constrained with considerable perioperative morbidity and mortality. The emergence of a hybrid approach utilizing visceral debranching with endovascular aneurysm repair has brought an alternative for high-risk patients. This study aimed to compare the short- and long-term outcomes between hybrid and open repairs in the treatment of thoracoabdominal aortic aneurysms.
METHODS:In this retrospectively observational study, patients with thoracoabdominal aortic aneurysm treated in a single center between January 2008 and December 2019 were reviewed, of whom 11 patients with hybrid repair, and 18 patients with open repair were identified. Demographic characteristic, operative data, perioperative morbidity and mortality, freedom from reintervention, and long-term survival were compared between the two groups.
RESULTS:In the hybrid repair group, the patients with dissection aneurysm, preoperative combined renal insufficiency, and American Society of Anesthesiologists (ASA) score of 3 or more were significantly overwhelming than in the open repair group. The operation time of debranching hybrid repair was (445±85) min, and the intraoperative blood loss was (955±599) mL. There were 2 cases of complications in the early 30 days after surgery, without paraplegia, and 1 case died. The 30-day complication rate was 18.2%, and the 30-day mortality was 9.1%. The operation time of the patients with open repair was (560±245) min, and the intraoperative blood loss was (6 100±4 536) mL. Twelve patients had complications in the early 30 days after surgery, including 1 paraplegia and 4 deaths within 30 days. The 30-day complication rate was 66.7%, and the 30-day mortality was 22.2%. The bleeding volume in hybrid repair was significantly reduced compared with open repair (P < 0.001). Besides, the incidence of 30-day complications in hybrid surgery was significantly reduced (P=0.011). During the follow-up period, there were 4 reinterventions and 3 deaths in hybrid repair group. The 1-year, 5-year, and 10-year all-cause survival rates were 72%, 54%, and 29%, respectively. In open repair group, reintervention was performed in 1 case and 5 cases died, and the 1-year, 5-year, and 10-year all-cause survival rates were 81%, 71%, and 35%, respectively. There was no significant difference between hybrid repair and open repair in all-cause survival and aneurysm-specific survival.
CONCLUSION:Hybrid approach utilizing visceral debranching with endovascular aneurysm repair is a safe and effective surgical method for high-risk patients with thoracoabdominal aortic aneurysms. The incidence of early postoperative complications and mortality is significantly reduced compared with traditional surgery, but the efficacy in the medium and long term still needs to be improved.
