P137. The Use of "BioGlue" for the Repair of Aortic Insufficiency in Acute Aortic Dissection Ehud Raanani, Georgios Georghiou, Alex Kogan, Boniface Wandwi, Alex Sagie, Yaron Shapira, Bernardo Alex Vidne Departments of Cardiothoracic Surgery and Cardiology Rabin Medical Center, Petach-Tikva, Israel OBJECTIVES: Preserving of the aortic valve has several advantages for patients undergoing repair of acute aortic dissection. We describe our experience with the use of a new bioadhesive (BioGlue, Cryolife) for the repair of the aortic root in acute dissection. METHODS: BioGlue is composed of bovine serum albumin (BSA) and glutaraldehyde (GA). GA exposure causes lysine molecules of BSA, extracellular proteins and cell surfaces to bind to each other creating a strong scaffold. From January 2001 to December 2002 BioGlue was used to repair the aortic root of 21 patients with acute aortic dissection. Moderate or severe insufficiency was present in 16 cases, mild in 5. The mechanism of insufficiency was commissure detachment in 15 cases, penetration of the intimal flap into the valve in 3 and dilatation of the sinotubular junction in 3. The aortic valve was re-suspended to the aortic wall using pledgeted sutures. BioGlue was used to adhere the dissected layers of the aortic root and create stronger tissue for sewing. Two patients required complete resection of the sinuses and aortic root remodeling using Dacron graft. RESULTS: There were 2 operative deaths. Postoperative TEE showed mild or no aortic insufficiency in 17 patients and moderate in two. During follow up (mean 13 months) none of the patients required reoperation for re-dissection, delayed rupture or aortic insufficiency. CONCLUSIONS: BioGlue is useful for aortic valve repair during aortic dissection. BioGlue is less toxic and has stronger glue effect than older surgical glues, and will likely prove to have superior long-term results.
