Four Cases of Granulation Formation after Wrapping of Cerebral Aneurysm with Cotton Fiber

Abstract

We report 4 cases of granulation formation after wrapping of cerebral aneurysm with cotton fiber. The cerebral aneurysms were wrapped with cotton fiber and reinforced with cyanoacrylates product. Granuloma was produced after wrapping in 2 cases, in 1 case of which the parent artery was completely obliterated. This complication might have been due to the operative technique: the aneurysm and circumference of the parent artery was completely wrapped with cotton fiber product.
Inflammatory granulation reaction was also observed in the other 2 cases, suggesting that only a small quantity of cotton fiber should be used for wrapping.
