Foreign material reaction to BioGlue® as a possible cause of cardiac tamponade.
ABSTRACT We describe the case of a 65-year-old female patient who underwent aortic valve reconstruction for aortic valve stenosis. During the operation, repair of a left ventricular laceration produced by a left ventricular vent was necessary. BioGlue® (CryoLife, Atlanta, GA, USA) and pledgeted sutures were used for repair. Pericardial effusion with signs of cardiac tamponade developed five months later. The patient was treated successfully by the removal of all foreign material and part of the BioGlue®. Microbiological findings were sterile. Histology showed a chronic granulomatous inflammatory response suggesting a foreign material reaction to BioGlue® as the cause of the effusion. Though all visible material was removed, the risk of pericardial effusion still persists as part of the BioGlue® remained within the ventricular wall.

ABSTRACT: We describe the development of a highly elastic and adhesive surgical tissue sealant, based on photochemically crosslinked gelatin, for sealing sutured incisions in the gastrointestinal (GI) tract in a rabbit surgical model and in a canine colon anastomosis study. The study included in vitro assessment of mechanical parameters of the tissue sealant and in vivo analysis of burst strength and histology at 24 h, 3 days and 7 days post surgery, in a rabbit model, to assess progress of wound healing at the suture sites. Utility of this sealant to repair and seal a lower colonic resection and anastomosis procedure in a canine model was also investigated. We show that a photopolymerised gelatin tissue sealant provides effective sealing of GI incisions and facilitates wound healing with no evidence of inflammation up to 28 days post-surgery. Blending of derivatised gelatin with underivatised gelatin allowed tuning of elasticity and elastic modulus of the photopolymerised sealant to suit surgical applications. High tissue adhesive strength was maintained at all blend ratios and exceeded 100 kPa. This highly elastic and adhesive photopolymerised gelatin tissue sealant offers a number of advantages over currently available sealants suitable for GI surgical procedures.Journal of Gastrointestinal Surgery 11/2011; 16(4):744-52. · 2.36 Impact Factor

ABSTRACT: Acute type A aortic dissection (AAAD) remains a lethal disease. With advances in operative methods and perioperative management, surgical outcomes continue to improve, but in-hospital mortality still ranges from 10 to 30 % in most series. The surgical technique of choice for aortic root repair remains controversial. Surgical glue created a breakthrough in surgery for acute aortic dissection. We review the surgical techniques with the use of surgical glue for AAAD.General Thoracic and Cardiovascular Surgery 11/2013;
