ABSTRACT

Objective:

To evaluate the short-term outcomes of cuff wrapping technique using remnant aortic wall in modified Bentall procedure.

Methods:

Between January 2018 and December 2018, 23 patients underwent modified Bentall procedure with the remnant aortic wall as a cuff to cover the sewing area of composite valved graft and the aortic annulus for proximal hemostasis. After the sewing ring of the composite valved graft was sutured to the aortic annulus by continuous suture, the remnant aortic wall was sutured to the graft just distal to the sewing ring by continuous suture. There were 21 males and 2 females, aged from 22 to 72 with a mean of(50.96±13.23)years. Short-term outcomes were assessed by cardiopulmonary bypass time, clamp aorta time, mechanical ventilation time, ICU time, postoperative stay time, effusion drainage till the first postoperative day, Left ventricular end diastolic diameter(LVEDD), left ventricular ejection fraction(LVEF), and follow-up results.

Results:

There were no postoperative and follow-up death. Cardiopulmonary bypass time was(157.74±39.85)min, ranged from 114 to 275 min; clamp aorta time(122.61±30.25)min, ranged from 84 to 212 min; mechanical ventilation time(11.65±3.08)h, ranged from 7.87 to 20.33 h; ICU time(81.43±45.88) h, ranged from 15.18 to 184.77 h; postoperative stay time(8.73±2.80)days, ranged from 6 to 15 days. Effusion drainage was(336.82±117.65)ml, ranged from 200 to 670 ml till the first postoperative day. Follow-up was performed from 19 to 30 months, with a mean of(23.17±3.17)months. There were significant differences between preoperative LVEDD and postoperative LVEDD before discharge[(49.78±6.21)mm vs.(58.78±10.54)mm, P<0.05]; There were a little decrease of follow-up LVEDD compared with postoperative LVEDD, but no significant difference between them[(48.87±4.63)mm vs.(49.78±6.21)mm, P>0.05] . There were a little decrease of postoperative LVEF compared with preoperative LVEF, but no significant difference between them(0.57±0.07 vs. 0.59±0.05, P>0.05). There were significant differences between follow-up LVEF and preoperative LVEF(0.62±0.04 vs. 0.57±0.07, P<0.05), postoperative LVEF before discharge( P<0.05).

Conclusion:

Cuff wrapping technique using remnant aortic wall in modified Bentall procedure has got good short-term results. This modification may be a simple, effective way in controlling proximal bleeding.
