Protocol for creation of a risk scoring system for acute type A aortic dissection surgery

Stanford type A aortic dissection is a kind of cardiovascular disease which seriously threatens human life and health. It has the characteristics of rapid onset, rapid progress and high mortality. Surgical treatment is a recognized treatment for type A aortic dissection. There are many disputed places in the actual clinical work about the timing, prognosis and methods of the operation. This study aims to establish an early mortality risk scoring system for acute Stanford A aortic dissection surgery patients.

Methods and analysis

The structured data of patients with acute type A aortic dissection were collected. The primary outcome is death during hospitalization. Secondary outcomes will include re-operation and related complications. A risk scoring system of patients with acute type A aortic dissection undergoing surgical treatment will be established. Prospective data will be used to validate the risk stratification ability and accuracy of the model in operative risk prediction.
