Communicating hydrocephalus after endovascular coiling of unruptured aneurysms

Report of 2 cases

Restricted access

✓ To the authors' knowledge, only 1 case of communicating hydrocephalus after endovascular coiling of unruptured brain aneurysms has been reported previously. Here, they report on 2 such cases of delayed communicating hydrocephalus after treatment with hydrogel-coated coils and offer the first histopathological evidence of foreign material, presumably related to the coils, as the cause of hydrocephalus.

Abbreviations used in this paper: CSF = cerebrospinal fluid; MR = magnetic resonance; RBC = red blood cell; VP = ventriculo-peritoneal; WBC = white blood cell.
