OBJECTIVE The current study retrospectively evaluated whether the percutaneous N-butyl cyanoacrylate (NBCA) seal-off technique is an effective treatment for controlling the angioplasty-related ruptures, which are irresponsive to prolonged balloon tamponade, during interventions for failed or failing hemodialysis vascular accesses. MATERIALS AND METHODS We reviewed 1588 interventions performed...

BACKGROUND AND OBJECTIVES Gynecological laparoscopy is a procedure associated to a high incidence of postoperative nausea and vomiting (PONV). This study aimed at comparing the efficacy of propofol or propofol plus dexamethasone in preventing PONV in patients submitted to gynecological laparoscopy. METHODS Forty female patients, physical status ASA I and II, aged 18 to 46 years, with no previ...

CONTEXT Band ligation (BL) is the most appropriate endoscopic treatment for acute bleeding or prophylaxis of esophageal variceal bleeding. Sclerotherapy with N-butyl-2-cyanoacrylate (CY) can be an alternative for patients with advanced liver disease. Bacteremia is an infrequent complication after BL while the bacteremia rate following treatment with CY for esophageal varices remains unknown. ...

The combination of the recently introduced soft lithographic technique of inverted microcontact printing (i-muCP) and spin-coated films of polystyrene- block-poly( tert-butyl acrylate) (PS 690- b-P tBA 1210) as a reactive platform is shown to yield a versatile approach for the facile fabrication of topographically structured and chemically patterned biointerfaces with characteristic spacings an...

Poly(butylcyanoacrylate) nanoparticles were prepared by dispersion polymerization (DP) and emulsion polymerization (EP) of n-butyl cyanoacrylate monomer. The particles were characterized by infrared spectroscopy, differential scanning calorimetry, X-ray diffractometry and transmission electron microscopy. Particle properties such as size and zeta potential were determined for nanoparticles prep...

BACKGROUND In surgical and endoscopic procedures, tissue adhesives are commonly used as reinforcement of sutures or as bonding and hemostatic agents. Fibrin glues do not guarantee adequate properties for many clinical applications; on the contrary, cyanoacrylate glues guarantee high bonding strength between biologic tissues. The aim of this study was to provide evidence regarding adhesive and s...

Poly(butylcyanoacrylate) nanoparticles (PBCN) as biodegradable and biocompatible devices have gained interest as a colloidal drug delivery system. Their main technological advantage is the possibility of preparation by anionic polymerization in aqueous medium without addition of any initiator that could have undesirable side effects. Unfortunately, in such conditions arises a problem with the e...

A 34-year-old man, who had been treated with an endoscopic injection of a mixture of n-butyl-2-cyanoacrylate (Histoacryl) and Lipiodol for control of variceal bleeding 6 months previously, presented with an intracardiac mass in the right atrium (RA). Two-dimensional echocardiography revealed an intracardiac mass in the RA that appeared to extend from the inferior vena cava. The origin of the sc...

delivering endoscopic therapies due to the higher incidence of gastrointestinal (GI) diseases (such as bleeding peptic ulcer) that are amenable to such therapeutic modalities. The other reason (and a more philosophical one) may have something to do with the basic characteristics of GI or pulmonary physicians. Could it be that the physicians who choose gastroenterology as a profession are more l...

Total occlusion of dural arteriovenous fistulas (DAVFs) via transarterial embolization is difficult due to the rich anastomotic network of the dural/falcine plethora of feeding arteries, blood supply to cranial nerves, and extracranial to intracranial anastomoses. Incomplete occlusion of the fistulas will result in recanalization of the DAVF from the multiple collateral arteries constituting th...
