Acute type A aortic dissection (ATAAD) is a life-threatening cardiovascular disease. Current guidelines recommend that ascending aortic replacement be performed when the ascending aorta is 5.5 cm in non-syndromic patients, while in syndormic patients, it should be replaced if the diameter reaches 4.5 cm in the sinus of Valsalva and 5.0 cm in the ascending aorta.
New approach for ascending aorta aneurysm management should be considered for prevention of ATAAD.
The objective of our study was to evaluate the correlation of the diameter of dissected ascending aorta in patients with ATAAD with preoperative adverse events, such as neurological dysfunctions and hemodynamic instability.
A retrospective analysis was performed on patients who were admitted to our hospital for ATAAD treatment. In all patients, the diameter of dissected ascending aorta was measured and its association with adverse events was analyzed.
The diameter of dissected ascending aorta was not associated with adverse events. Also, the diameter of the ascending aorta was not associated with 30-d mortality and ICU and hospital stay postoperatively.
Maybe the threshold of ascending aorta aneurysm should be revised for lower limits regarding the risk for late acute dissection
Randomized controlled studies including more patients should be performed to confirm our results and preventive ascending aorta replacement may be considered for prevention of ATAAD.
