Use of Plastic Adhesive for Reinforcement of a Ruptured Intracranial Aneurysm

Dur ing the pas t decade, the feasibil i ty of t rea t ing in t r ac ran ia l aneurysms wi th syn the t i c coatings has been i n v e s t i g a t e d ) '7'1~ Difficulties have been encounte red in finding sui table mater i als and proper solvents, a t t a in ing op t imal condit ions of the surface, and developing techniques of i n s t rumen ta t i on . One of the more promis ing substances , E a s t m a n 910 monomer,* has been under inves t iga t ion by members of the Neurological Divis ion of the St. Vincent ' s Hospi ta l of the Ci ty of New York. E a s t m a n 910 monomer (methyl -~-cyanoacrylate) is a sterile, TM wate ry subs tance which requires no solvent . I t polymerizes in the presence of mois ture and pressure, forming an a d h e r e a t film. This syn the t i c will bond securely a muscle p a t c h to a site of a r t e r io tomy capable of withs t and ing an in t r a lumina l pressure over 300 ram. H g 3 Modif ica t ions of this mater ia l have been used in the repa i r of b lood vessels and o ther tissues? -4,7'9,~'~4 C a r t o n et al2 recorded the successful p l acement of a dural p a t c h to a defect a t t he site of an a n e u r y s m which had to rn f rom the in t ra crania l in te rna l carot id ar tery .
