Title:
The Association of the Cerebral Protection Strategy with Early Mortality and Postoperative Stroke in Acute Type A Aortic Dissection: A Systematic Review and Meta-Analysis
Description:
<jats:p>Objective. The optimal cerebral protection strategy in acute type A aortic dissection (ATAAD) is still without a clear consensus. The purpose of this meta-analysis was to compare the outcome of different cerebral protection strategies on ATAAD patients. Materials and Methods. We conducted a systematic review including all studies concerning surgically managed ATAAD patients between 1.1.2010 and 28.2.2022 and reporting the use of cerebral protection strategies in three large databases (Pubmed, Cochrane library, and Scopus). The main outcome events were 30-day mortality and a postoperative stroke rate. The pooled event rates adjusted by age, gender, CPB duration, circulatory arrest duration, and total arch reconstruction rate were calculated. Results. Overall, 39 articles were included covering a total of 16, 876 ATAAD patients. The estimated adjusted pooled early mortality rate was 10.1% (95% confidence interval [CI] 9.1–11.3%) in the ACP group, 15.9% (13.3–18.9%) in the RCP group, and 11.6% (9.2–14.5%) in the HCA group. Compared to the RCP group, ACP and HCA demonstrated lower early mortality (RCP vs. ACP odds-ratio 1.66 [1.28–2.15],<jats:inline-formula><math xmlns="http://www.w3.org/1998/Math/MathML" id="M1"><mi>p</mi></math></jats:inline-formula> < 0.001; RCP vs. HCA odds-ratio 1.45 [1.02–2.07],<jats:inline-formula><math xmlns="http://www.w3.org/1998/Math/MathML" id="M2"><mi>p</mi></math></jats:inline-formula> = 0.039). The adjusted pooled stroke rate was 9.0% (8.3–9.8%) in the ACP group, 10.5% (9.3–11.7%) in the RCP group, and 9.1% (8.1–10.2%) in the HCA group. Conclusion. Early mortality might be more common in ATAAD patients treated with RCP compared to ACP and HCA. With regards to postoperative stroke, the results were inconclusive despite the trending inferiority of RCP compared to the other strategies.</jats:p>
