Short-term results of sleeve wrapping technique using remnant aortic wall in modified Bentall procedure
Objective To evaluate the short-term results of sleeve wrapping technique using remnant aortic wall in modified Bentall procedure.Methods The patients undergoing modified Bentall procedure with the remnant aortic wall as a sleeve to cover the sewing area of composite valved graft and the aortic annulus for proximal hemostasis between March 2021 and March 2022 in Shenzhen Fuwai Hospital were enrolled.Short-term results were assessed by cardiopulmonary bypass time,aortic clamping time,mechanical ventilation time,ICU stay,postoperative hospital stay,effusion drainage on the first postoperative day,left ventricular ejection fraction(LVEF),left ventricular end diastolic diameter(LVEDD),and follow-up results.Results A total of 14 patients were collected,including 12 males and 2 females,with a mean age of 55.33±10.57 years.There was no postoperative or follow-up death.Cardiopulmonary bypass time was 147.90±21.29 min,aortic clamping time was 115.70±15.23 min,mechanical ventilation time was 19.42±8.98 h,ICU stay was 99.08±49.42 h,and postoperative hospital stay was 16.33±2.74 d.Thoracic drainage volume was 333.33±91.98 mL on the first postoperative day.Only 2 patients required blood transfusion(4.5 U and 2 U,respectively).During the follow-up of 6.17±3.69 months,there was no death,no aortic or valve-related complications.There was statistical difference in the LVEDD between preoperation and before discharge after surgery(P＜0.001),and between half a year after surgery and before discharge after surgery(P＜0.001).There was a little decrease of LVEF before discharge after surgery compared with preoperative LVEF,but there was no statistical difference(P=0.219).There was no statistical difference in the LVEF half a year after operation compared with that before operation(P=1.000).Conclusion Sleeve wrapping technique using remnant aortic wall in modified Bentall procedure has good short-term results.This modification may be a simple,effective way in controlling proximal bleeding.
