Purpose

To identify risk factors for postoperative complications in Stanford Type A aortic dissection (TAAD) patients, a risk prediction model was developed and validated.

Methods

The study included a specific cohort of TAAD patients (aged 32-66 years) who underwent surgery with general anesthesia and cardiopulmonary bypass.

n = 522 patients

Results

correctly flags most complication risk, better discrimination as it nears 1

77.59%

Sensitivity

85.34%

Specificity

More results

A risk model was created using multivariate logistic regression analysis.

Of the 522 patients, 174 (33.33%) experienced at least one major postoperative complication, including neurological, respiratory, renal, or other organ dysfunction.

More results

Based on the logistic regression equation, logistic (P) = -7.458 + 0.056 × 1 + 0.102 × 2 + 0.374 × 3 + 0.018 × 4 + 0.026 × 5, a multivariate logistic regression risk model was developed to calculate the risk of postoperative complications, p = 1/1 + exp (-7.458 + 0.056 × 1 + 0.102 × 2 + 0.374 × 3 + 0.018 × 4 + 0.026 × 5).

Conclusion

Due to the specific age distribution of the study population, the results should be applied with caution to elderly patients (> 66 years).
