Abstract

Open repair of type II thoracoabdominal aortic aneurysms (TAAAs) remains a challenging procedure. Staged procedures could decrease the incidence and severity of complications after complex aortic repair. In the present report, we have described a strategy using thoracic endovascular aortic repair (TEVAR) for proximal repair, followed by distal open repair. From 2014 to 2018, 14 patients had undergone TEVAR, followed by distal open repair, for type II TAAAs. All patients should have a suitable proximal landing zone according to the current guidelines. In cases of chronic dissection, false lumen embolization was performed to achieve total exclusion. The mean patient age was 48 ± 15 years. Of the 14 patients, 5 had had Marfan syndrome (36%) and 6 had undergone previous aortic arch repair (43%). Ten patients had had a chronic dissection. The maximal aortic diameter was 73 ± 12 mm. The TEVAR technical success rate was 100%. The aortic length coverage was 211 ± 63 mm. The number of covered segmental arteries was 6 (range, 4-13). Two endoleaks were observed, one type Ib and one type II. The delay between TEVAR and open repair was 12 ± 8 weeks. Cerebrospinal fluid drainage was used in 13 patients. Six patients had undergone segmental artery reattachment during surgery. No spinal cord ischemic event was observed. One patient had died 5 weeks after open repair of multiple organ failure. During the 32 months of follow-up, no aortic-related deaths had occurred. No new aortic procedure was needed. The type Ib endoleak had resolved during open repair, and the type II TAAA had resolved spontaneously. The mean maximal thoracic aortic diameter had significantly decreased to 49 ± 8 mm (P < .0001). Aneurysmal shrinkage of ≥5 mm was observed in 13 patients (93%). Staged hybrid repair of type II TAAAs appears to be efficient, with low morbidity and mortality rates. This technique could improve postoperative outcomes after open repair, and TEVAR might have a role in ischemic preconditioning to protect against spinal cord ischemia.
