Extraintracranial anastomosis performed by means of biological gluing materials: experimental and clinical study.

A new surgical technique of extraintracranial anastomosis (EIA) is reported. End-to-side microvascular anastomosis is performed by applying four crossed-fixing sutures and by mantling a hemostatic sponge muff (eg, Spongostan) impregnated with fibrinogen-thrombin glue. Histopathological studies of microvascular anastomosis in animals and clinical results of 70 EIA operations showed that this surgical technique of anastomosis has certain advantages, namely that it reduces the number of sutures needed, is less traumatic to the vascular wall, ensures elastic vascular junction, and the glue and Spongostan used possess high biological inertness that provides a better physiological connection of vessels than conventional suturing. The highly hermetic vascular junction and absence of blood flow at the anastomosis site are achieved without additional suturing. The duration of the operation is significantly reduced. A full EIA function sets in comparatively early.
