Delayed Pulmonary Artery Rupture after Using BioGlue in Cardiac Surgery

A 56-year-old woman, who underwent cardiac surgery 3 months previously, presented to the emergency room with pulmonary artery rupture due to the cytotoxic effects of BioGlue (CryoLife Inc., Kennesaw, GA, USA). She was successfully treated with surgical management. Although surgical glue can be effectively used for hemostasis, it can induce delayed vascular complications. Therefore, surgical glue should be used cautiously.

A Case of Type A Acute Aortic Dissection in an Elderly Woman with Immune Thrombocytopenia Who Underwent Replacement of the Ascending Aorta and Aortic Arch and Later Required Aortic Root Replacement for Redissection of the Aortic Root / 日本心臓血管外科学会雑誌

We report a case of type A acute aortic dissection in an elderly woman with immune thrombocytopenia (ITP) who underwent replacement of the ascending aorta and aortic arch and later required aortic root replacement for redissection of the aortic root one month after her initial surgery. She was an 86-year-old woman with severe mitral regurgitation, and surgery was contraindicated because of her age and ITP. In October 2014, the patient presented with back pain. Computed tomography confirmed the diagnosis of her condition as type A acute aortic dissection, and she was immediately transferred to our hospital. Because echocardiography showed severe aortic regurgitation, severe mitral regurgitation, and moderate tricuspid regurgitation, we performed replacement of the ascending aorta and aortic arch, mitral valve repair, and tricuspid annuloplasty. We used Bioglue to fuse the false lumen of the type A acute aortic dissection and used a Teflon felt sandwich for the proximal anastomosis technique. Respiratory support was discontinued 91 h after her first operation ; however, 30 days after surgery, she developed a to-and-fro murmur-a sign of the progression of heart failure. Echocardiography showed aggravation of aortic regurgitation, and computed tomography showed aortic root redissection ; therefore, 39 days after the initial surgery, we performed aortic root replacement. During the operation, we found the entry under the proximal anastomosis with an almost semicircle form at the right coronary cusp to the noncoronary cusp, and the dissection extended close to the right coronary artery ; thus, we performed bypass to the right coronary artery. Pathologic findings did not establish a causal association between the redissection and Bioglue, and we believed the fragility of the tissue and the selection of the surgical procedure to be the cause of redissection. The patient was transferred to another hospital when she was able to walk and eat, which was 121 days after her first operation. The patient required 50 units of platelet transfusion during her first and second operations, but her bleeding was easily controlled during surgery. She needed two procedures of pericardium drainage for pericardiac effusion and cardiac tamponade, which may relate to ITP. The diagnosis of redissection of the aortic root was made 30 days after the patient's first operation, on the basis of exacerbation of the to-and-fro murmur. Here, we emphasize the clinical importance of basic observations over time, such as auscultation, that are liable to be overlooked in the intensive care unit.

Bioglue-Coated Teflon Sling Technique in Microvascular Decompression for Hemifacial Spasm Involving the Vertebral Artery

OBJECTIVE: Microvascular decompression (MVD) for hemifacial spasm (HFS) involving the vertebral artery (VA) can be technically challenging. We investigated the therapeutic effects of a bioglue-coated Teflon sling technique on the VA during MVD in 42 cases. METHODS: A bioglue-coated Teflon sling was crafted by the surgeon and applied to patients in whom neurovascular compression was caused by the VA. The radiologic data, intra-operative findings with detailed introduction of the procedure, and the clinical outcomes of each patient were reviewed and analyzed. RESULTS: The 42 patients included in the analysis consisted of 22 females and 20 males, with an average follow-up duration of 76 months (range 24–132 months). Intraoperative investigation revealed that an artery other than the VA was responsible for the neurovascular compression in all cases : posterior inferior cerebellar artery (PICA) in 23 patients (54.7%) and anterior inferior cerebellar artery (AICA) in 11 patients (26.2%). All patients became symptom-free after MVD. Neither recurrence nor postoperative neurological deficit was noted during the 2-year follow-up, except in one patient who developed permanent deafness. Cerebrospinal fluid (CSF) leak occurred in three patients, and one required dural repair. CONCLUSION: Transposition of the VA using a bioglue-coated Teflon sling is a safe and effective surgical technique for HFS involving the VA. A future prospective study to compare clinical outcomes between groups with and without use of this novel technique is required.

Use of biological Glue (Bioglue®) in laparoscopic partial nephrectomy: a study in pigs

Introduction Partial nephrectomy is the standard of care for localized renal tumors. However, bleeding and warm ischemia time are still controversial when laparoscopic surgeries are carried out. Herein, we aim to compare the outcomes from laparoscopic partial nephrectomy with and without the use of biological glue with purified bovine albumin and glutaraldehyde (BioGlue®). Materials and Methods Twenty-four kidneys of 12 pigs were used in this study. A pre-determined lower pole segment was resected (3 cm x 1 cm) and one of two different hemostatic techniques was performed. In one kidney, hemostatic “U suture” (poliglecaprone 3.0) was performed and in the contra-lateral kidney, only the biological glue was applied. Data recorded was comprised of warm ischemia time (seconds) and estimated blood loss (mL) for each procedure. In cases of bleeding after glue administration, a complementary suture was done. Results Mean warm ischemia time was 492.9±113.1 (351-665) seconds and 746±185.3 (409-1125) seconds for biological glue and suture groups, respectively. There was a positive significant difference in terms of warm ischemia favoring the biological glue group over the suture group (p<0.001). Mean blood loss was 39.4 (0-115) mL for the biological glue group and 39.1 (5-120) mL for the suture group (p=0.62). Conclusion Biological glue is an important tool for laparoscopic partial nephrectomies. It is effective for hemostatic control in selected cases, and it can be used in combination with the traditional suture techniques. .

Influência da cola Bioglue® na deiscência de anastomose colônica: estudo experimental / Influence of Bioglue® surgical adhesive on colonic anastomosis dehiscence: experimental study

A grande parte da morbimortalidade associada com a cirurgia colorretal, é associada com a deiscência anastomótica. Trabalhos experimentais sobre a utilidade de adesivos tissulares nas anastomoses colônicas são controversos, assim como estudos clínicos prospectivos randomizados são ausentes. O adesivo cirúrgico BioGlue®, formado por dois componentes - albumina sérica bovina purificada e glutaraldeído, forma uma ligação co-valente entre esses dois componentes e as proteínas teciduais no local de aplicação. O objetivo do estudo é avaliar a eficácia da BioGlue® na prevenção da deiscência anastomótica colônica em ratos. Foram utilizados 30 ratos machos da raça Wistar albino. A anastomose colocolônica foi confeccionada com sutura em pontos separados com polipropileno 5-0 (grupo 1) e aplicação da cola BioGlue® envolvendo a anastomose (grupo 2). Avaliaram-se a formação e extensão das aderências, a pressão de ruptura nas anastomoses e as alterações histológicas. Apenas um animal do grupo 1 (7 por cento) faleceu, sendo constatada na necropsia, obstrução intestinal com grande distensão de alças. A mortalidade no grupo 2, por outro lado, foi de 10 animais (67 por cento), sendo observado: distensão de alças intestinais, vazamento anastomótico e, em algumas situações, franca peritonite fecal por deiscência quase que total da anastomose. O presente trabalho nos permitiu concluir que, o uso da Bioglue® nas anastomoses colônicas realizadas em ratos, promoveu um aumento na morbimortalidade que foi estatisticamente significante comparado à sutura convencional.

The great part of the morbimortality associated with the colorretal surgery, is related with the anastomotic dehiscence. Experimental trials on the utility of tissue adhesives in the colonic anastomosis are controversial, as well as prospective randomized clinical studies are absent. BioGlue® Surgical Adhesive(BSA) is a two-component surgical adhesive composed of purified bovine serum albumin and glutaraldehyde. The glutaraldehyde molecules covalently bond (cross-link) the BSA molecules to each other and, upon application, to the tissue proteins at the repair site. The aim of this study is to evaluate the effectiveness of the BioGlue® in the prevention of the anastomotic colonic dehiscence in rats. Thirty male Wistar rats had been used. The colocolonic anastomosis was confectioned with separate stitches with polypropylene 5-0 (group 1) and the application of the BioGlue® Surgical Adhesive (group 2). The formation and extension of the adhesions, the histological alterations and the rupture pressure had been evaluated. In the group 1, we have only 7 percent of mortality (01 animal), being evidenced in the autopsy, intestinal obstruction with major bowel distension. The mortality in group 2, on the other hand, was 67 percent (10 animals), being observed: bowel distension, anastomotic dehiscence and, in some situations, fecal peritonitis because of anastomotic total dehiscence. We concluded in the present study that, the use of BioGlue® Surgical Adhesive in colonic anastomosis in rats, is associated with an increase of the morbimortality in comparison with conventional suture which was statistically significant.

Tibial plateau fractures treated by internal fixation with bioglue compound and anatomic plate / 中华创伤骨科杂志

Objective To investigate the clinical effects of bioglue compound and anatomic plate in treatment of tibial plateau fractures. Methods 28 cases of tibial plateau fractures were treated by means of open reduction and internal fixation with bioglue compound and anatomic plate. The intervals between operation and injury ranged from 5 to 10 days. The amounts of bioglue compound implanted ranged from 3 to 8 grams. Results All the patients were followed up for 6 to 22 months. All the fractures healed satisfactorily without sunken joint surface. According to Mechant criteria, the result was excellent in 13 cases, good in 11 cases, moderate in 3 cases and poor in 1 case. The total excellent and good rate was 85.3 %. Conclusion Internal fixation with bioglue compound and anatomic plate can result in good effects in treatment of tibial plateau fractures, because the bioglue compound possesses high bone inductive potentialities to repair bone defects.
