[Hermetization of aortic sutures - the comparative analysis of methods]

Leakage of the ascending aortic sutures after the aortic valve replacement with the use of various methods of surgical hemostasis was studied. Results of 244 operations were analyzed. Thus, aortic leakage took place in 50 (20,5%) patients. One- or two-fold sewing was successfully used in 16 (32%) cases. The rest benefited from aortic suture fixation with the use of pericardial flap. Algorythm, implying usage of the auto- or xenopericardial flap after two-fold sewing failure, enabled exclusion of repeated aorta cross-clamping, decrease of the blood loss and hemotransfusion, and, therefore, decrease of postoperative complication and lethality rates.
