A clinico-experimental study on various wrapping materials of cerebral aneurysms.
In this paper, we discuss the results of a systemic study of various materials so far used for wrapping, using the intracranial arteries of 43 mongrel dogs. The findings obtained are: Muscle, fascia and dura observed began to show necrotic and absorbable change within 1 to 2 months after operation, suggesting their unreliability. Bemsheet was superior in this study in adhesiveness to the vascular wall, highly contributory to constructing a firm reinforced wall by proliferating collagen fibres in the space of stereo-reticular structure of cotton fibre. No change occurred in the cotton fibre itself with the passage of time. Lyodura had a poor adhesiveness to the vascular wall with detectable gap; in addition, it showed necrosis and absorption in the bending site. Coating with Aron alpha A had a relatively poor adhesiveness to the vascular wall and seemed to crack and disappear with time.
