Purpose. The optimal surgical strategy of aortic root in acute type A
aortic dissection (ATAAD) is controversial. The aim of this study was to
evaluate the feasibility and safety of “Sleeve” sinus Valsalva repair
for AAD limited to the non-coronary sinus or partial left and right
coronary sinus without involvement coronary artery ostia. Methods: From
Sep 2016 to Mar 2019, 20 patients with AAD involving non-coronary sinus
or partial left and right coronary sinus Valsalva underwent “Sleeve”
sinus Valsalva repair . Multi slice spiral computed tomography
angiography (MSCT) and three dimensional reconstruction were routinely
performed in all patients to assess the maximal diameters of each
segment of the aorta. Results. There was no early death in hospital and
one death during the 30-day postoperative period. Re-thoracotomy due to
bleeding was necessary in only 1 patient and no bleeding was related to
the proximal anastomosis. The post-operative drainage was 390.5±229.3mL.
During the following-up, the echocardiography showed the normal sinus of
Valsalva and aortic valvular function. The computed tomography
angiography showed normal aortic root without endovascular leak or
dissection around the sinus of Valsalva. All patients were free from
reoperation. Conclusions. “Sleeve” sinus Valsalva repair with Dacron
patch for aortic dissection limited to the non-coronary sinus or partial
left and right coronary sinus without involvement coronary artery ostia
was technically feasible and safe.
