Glubran2 is a cyanoacrylate-based synthetic glue modified by addition of a second monomer. Among its many advantages over traditional cyanoacrylate products, Glubran2 has a much lower thermal polymerization temperature than that of cyanoacrylates used for cutaneous application. For many years, the new glue has been widely used in neuroradiology endovascular treatments. Our study aimed to assess the use of Glubran2 to treat possible complications arising during the embolization of aneurysms or vascular malformations like AVM or fistulae. A complication encountered in some of these cases is rupture of the vessel wall by the microguide or perforation of the aneurysmal sac by the coils used for embolization. This complication could be overcome by injecting Glubran2 into the rupture point but this would put the glue directly in contact with the subarachnoid space and possibly reach adjacent brain tissue. The aim of this experimental study was to place the glue in direct contact with brain tissue to ascertain its immediate compatibility and tolerability in vivo and any ensuing tissue damage. Three swine underwent neurosurgical procedures and survived for different times after which they were slaughtered and their brains explanted and sent for macroscopic and microscopic investigation by the Pathological Anatomy Service. As a whole, Glubran2 was well tolerated in vivo and did not cause major damage in direct contact with brain tissue.
