Objective: To provide an updated systematic review and meta-analysis with meta-regression of safety and efficacy of fenestrated/branched endovascular repair of thoracoabdominal aortic aneurysms (TAAAs) compared with open repair. Summary background data: Endovascular repair of TAAAs may be a promising alternative to open surgery by reducing invasiveness and expanding the eligible population, but evidence remains limited. Methods: We applied PRISMA to retrieve, quantitatively pool, and critically evaluate the efficacy and safety (including 30-day mortality, reintervention, spinal cord injury, SCI, and renal injury) of both approaches. Original studies were retrieved from PubMed, Embase and Cochrane Library until 20 April 2022, excluding papers reporting less than 10 patients. Pooled proportions and means were determined using a random-effects model. Heterogeneity between studies was evaluated with I2 statistics. Results: Sixty-four studies met the pre-defined inclusion criteria. Endovascular cohort patients were older and had higher rates of comorbidities. Endovascular repair was associated with similar proportions of mortality (0.07, 95% confidence interval, CI, 0.06-0.08) compared with open repair (0.09, 95%CI 0.08-0.12; P-value=0.22), higher proportions of reintervention (0.19, 95%CI 0.13-0.26, vs. 0.06, 95%CI 0.04-0.10; P-value<0.01), similar proportions of transient SCI (0.07, 95%CI 0.05-0.09, vs. 0.06, 95%CI 0.05-0.08; P-value=0.28), lower proportions of permanent SCI (0.04, 95%CI 0.03-0.05, vs. 0.06, 95%CI 0.05-0.07; P-value<0.01) and renal injury (0.08, 95%CI 0.06-0.10, vs. 0.13, 95%CI 0.09-0.17; P-value=0.02). Results were affected by high heterogeneity and potential publication bias. Conclusions: Despite these limitations and the lack of randomised trials, this meta-analysis suggests that endovascular TAAA repair could be a safer alternative to the open approach.

Abstract

Objective: To provide an updated systematic review and meta-analysis with meta-regression of safety and efficacy of fenestrated/branched endovascular repair of thoracoabdominal aortic aneurysms (TAAAs) compared with open repair. Summary background data: Endovascular repair of TAAAs may be a promising alternative to open surgery by reducing invasiveness and expanding the eligible population, but evidence remains limited. Methods: We applied PRISMA to retrieve, quantitatively pool, and critically evaluate the efficacy and safety (including 30-day mortality, reintervention, spinal cord injury, SCI, and renal injury) of both approaches. Original studies were retrieved from PubMed, Embase and Cochrane Library until 20 April 2022, excluding papers reporting less than 10 patients. Pooled proportions and means were determined using a random-effects model. Heterogeneity between studies was evaluated with I2 statistics. Results: Sixty-four studies met the pre-defined inclusion criteria. Endovascular cohort patients were older and had higher rates of comorbidities. Endovascular repair was associated with similar proportions of mortality (0.07, 95% confidence interval, CI, 0.06-0.08) compared with open repair (0.09, 95%CI 0.08-0.12; P-value=0.22), higher proportions of reintervention (0.19, 95%CI 0.13-0.26, vs. 0.06, 95%CI 0.04-0.10; P-value<0.01), similar proportions of transient SCI (0.07, 95%CI 0.05-0.09, vs. 0.06, 95%CI 0.05-0.08; P-value=0.28), lower proportions of permanent SCI (0.04, 95%CI 0.03-0.05, vs. 0.06, 95%CI 0.05-0.07; P-value<0.01) and renal injury (0.08, 95%CI 0.06-0.10, vs. 0.13, 95%CI 0.09-0.17; P-value=0.02).
