  • Title: A Meta-Analysis of Total Arch Replacement With Frozen Elephant Trunk in Acute Type A Aortic Dissection.
    Author: Takagi H, Umemoto T, ALICE Group.
    Journal: Vasc Endovascular Surg; 2016 Jan; 50(1):33-46. PubMed ID: 26767803.
    Abstract:
    OBJECTIVES: To assess the safety and efficacy, we performed a meta-analysis of total arch replacement with frozen elephant trunk in exclusive acute type A (neither chronic nor type B) aortic dissection. METHODS: Databases including MEDLINE and EMBASE were searched through March 2015 using Web-based search engines (PubMed and OVID). Eligible studies were case series of frozen elephant trunk enrolling patients with acute type A (neither chronic nor type B) aortic dissection reporting at least early (in-hospital or 30-day) all-cause mortality. Study-specific estimates were combined in both fixed- and random-effect models. RESULTS: Fifteen studies enrolling 1279 patients were identified and included. Pooled analyses demonstrated the cardiopulmonary bypass time of 207.1 (95% confidence interval [CI], 186.1-228.1) minutes, aortic cross-clamp time of 123.3 (95% CI, 113.1-133.5) minutes, selective antegrade cerebral perfusion time of 49.3 (95% CI, 37.6-61.0) minutes, hypothermic circulatory arrest time of 39.0 (95% CI, 30.7-47.2) minutes, early mortality of 9.2% (95% CI, 7.7-11.0%), stroke of 4.8% (95% CI, 2.5-9.0%), spinal cord injury of 3.5% (95% CI, 1.9-6.6%), mid- to long-term (≥1-year) overall mortality of 13.0% (95% CI, 10.4-16.0%), reintervention of 9.6% (95% CI, 5.6-15.8%), and false lumen thrombosis of 96.8% (95% CI, 90.7-98.9%). CONCLUSIONS: Total arch replacement with frozen elephant trunk provides a safe alternative to that with conventional elephant trunk in patients with acute type A aortic dissection, with acceptable early mortality and morbidity. The rates of mid- to long-term reintervention and false lumen non-thrombosis may be lower in patients undergoing the frozen than conventional elephant trunk procedure.
