Increasing atmospheric temperature implicates increasing risk for acute type A dissection in hypertensive patients.

Background: Acute type A aortic dissection (AAAD) is a life-threatening condition with high mortality within 24 hours. We hypothesized if there is a correlation between seasonal weather changes and the occurrence of AAAD. The aim of the present study was to identify seasonal specific weather and patient characteristics predicting the occurrence of AAAD.

Survival, Neurologic Injury, and Kidney Function after Surgery for Acute Type A Aortic Dissection.

Background: To analyze survival, neurologic injury, and kidney function after acute type A aortic dissection.

Methods: A total of 445 patients undergoing surgery for acute type A aortic dissection were analyzed. Evaluation according to risk factors for mortality, neurologic injury, and kidney function was performed.
