An observational study in Cumulative Sum Learning Curves and Stanford Type A Aorta Dissection, sponsored by Yunlong Fan. Completed at 1 site in China. Open to participants aged 18 Years to 65 Years. Per ClinicalTrials.gov, last updated 2021-11-19.
Sponsored by Yunlong Fan · Observational
stanford type A aortic dissection is the most common cause of death caused by aortic disease in Chinese mainland. Patients who are hospitalized need immediate surgical treatment.Emergency aortic arch replacement is difficult and risky. Different surgical methods have different effects on postoperative prognosis. Aortic arch replacement is divided into total-arch replacement (Sun's operation) and hemi-arch replacement. In this study, and the learning Curve of Aortic Arch Replacement Surgery was evaluated with cumulative cum curve.
386 studies on the registry are indexed under Aortic Dissection; 117 are open to participants now.
This study's enrollment of 139 is below the median of 183 across 180 observational studies indexed under Aortic Dissection.

Exclusion Criteria:
Cardiopulmonary bypass (CPB) time
Cardiopulmonary bypass (CPB) time was used as the main variables for evaluation and visualization of the aorta dissection surgery learning curve using Cumulative sum.Cumulative sum (CUSUM) is a statistical method that focuses on results rather than on the process of performing a program skills, it generates graphs that allow for quick detection of deviations from pre-established standards and is an alternative tool that can be used to evaluate the performance of individual program. CUSUM can be generated based on set acceptable and unacceptable failure rates and the degree to which type 1(α) and type 2(β) errors (false positive and false negative errors) will be tolerated. CUSUM was defined as Sn = ∑(Xi -p0), where Xi = 0 for success and Xi = 1 for failure, p0 is the target reference.
Time frame: Intra-operative
