Background:
Management of acute type A intramural hematoma (IMH) is a controversial topic. In our study, we aim to analyze the survival outcomes in local patients with acute type A IMH and a meta-analysis on survival in type A IMH treated medically versus surgically was performed.
Methods:
From 2014 to 2019, 65 patients with acute type A IMH were selected for analysis. Primary outcome of interest was 1 year all cause survival. The rate of aortic-related events in the medical group was evaluated. PubMed and Embase were searched for meta-analysis.
Results:
The mean age of our cohort was 61.7±9.7 years. Of the 65 patients, 40% had emergency operation. Overall 1-year survival was 96.9%. The 1-year survival was 94.9% for the medical group. 46.2% of the medical group required aortic intervention at a mean duration of 191±168 days. Maximal aortic diameter (MAD) ≥45 mm was predictive of aortic-related events in the medical group (OR: 7.0; 95% CI, 1.7-29.4; P=0.008). For the meta-analysis, 21 studies were identified, and 900 patients were included. Emergent surgery was associated with improved survival in type A IMH (OR: 0.76; 95% CI, 0.29-1.97, P=0.58; I2=27%).
Conclusions:
The 1-year survival after type A IMH was promising, regardless of approach. The conservative-first approach was found to be safe & feasible, and upfront surgery remained the management of choice in general. Patients with MAD ≥45 mm was associated with subsequent aortic intervention in the medical-first group.
