ABSTRACT
Pericardial effusions often complicate the postoperative course of ascending aortic surgery. We evaluated whether an unconventional use of hemostatic fleeces (TachoSil, Nycomed; Austria), wrapped around aortic tube grafts, may reduce such complication. Twenty-nine consecutive patients undergoing button-Bentall were submitted - according to surgeon's choice - to 360 degrees wrapping of the aortic grafts with hemostatic fleeces immediately before sternal wiring (11 patients - group A) or sternal wiring without any wrapping of the prosthesis (18 patients - group B). Hospital outcome was recorded. No differences were recorded in hospital mortality and major organ morbidity. When pericardial complications were considered, group A showed lower chest drains (P=0.0001), time of chest drainage (P=0.002), pretamponade/tamponade with need for pericardiocentesis (P=0.039), predischarge echocardiographic amount of pericardial effusion (P=0.026), fever (P=0.029), need for anti-inflammatory (P=0.05) or antibiotic drugs (P=0.007), hospital stay (P=0.010) and white blood cell count (P=0.016 on postoperative day 3; P=0.014 on day 6). Wrapping of aortic tube grafts with hemostatic fleeces is effective in reducing pericardial effusion and its deleterious effects following aortic surgery.
