Objective To evaluate the effects of 'patch-skill'in the management of refractory bleeding during the process of open heart surgery.Methods Between May 2007 to Oetober 2008,7 patients undergoing open-heart surgery experienced active bleeding.Autologous perieardial patches were used in 6 patients, and polyester patch in the other one.The patches were sutured continuously by 5-0 Prolene suture.Results The 24 hour chest tube output was less than 500 ml in all 7 cases after operation.There were no death, secondly active bleeding,or mediastinal in-faction.Conclusion The'patch-skill' can effectively control the refractory bleeding during open heart surgery.Au-tologous perieardial patehe is the first choice because it has multiple advantages.The polyester patch ean be used al-ternatively when autologous pereardiurn cannot be used (for various reasons such as edema and infection).

Objective To explore the surgical treatment for patients with aortic valve disease and ascending aorta dilatation.Methods The patients were divided into two groups according to the condition of aortic valve leaflet and surgical treatment.The changes of ascending aorta after different treatment were measured by echocardiography.Results Among tricuspid aortic valve patients,diameter of ascending aorta in patients with simple aortic valve replacement decreased by 0.471 mm averagely per year,while diameter of ascending aorta in patients with the concomitant ascending aorta angioplasty decreased 0.27 mm averagely per year.Among bicuspid aortic valve patients,diameter of ascending aorta in patients with simple aortic valve replacement increased by 2.28 mm averagely per year,while diameter of ascending aorta in patients with the concomitant ascending aorta angioplasty increased 2.923 mm averagely per year.Conclusion The patients with bicuspid aortic valve are more likely to develop ascending aorta dilatation after the operation of the aortic valve.Patients with bicuspid aortic valve should undergo ascending aorta replacement when aorta diameters are more than 40 mm.Patients with tricuspid aortic valve undergoing surgery must be very cautious.
