Analysis of risk factors for perifocal oedema after endovascular embolization of unruptured intracranial arterial aneurysms

摘要

BackgroundEndovascular embolization is a treatment of choice for the management of unruptured intracranial aneurysms, but sometimes is complicated with perianeurysmal oedema. The aim of our study was to establish incidence and outcomes of perianeurysmal oedema after endovascular coiling of unruptured intracranial aneurysms, and to reveal possible risk factors for development of this potentially serious complication.
