Endovascular Coiling as the First Treatment Strategy for Ruptured Pericallosal Artery Aneurysms: Results, Complications, and Follow Up

摘要

We apply endovascular coiling as the first treatment option for ruptured pericallosal artery aneurysms. We conducted a retrospective analysis of the clinical and radiological outcomes of this treatment strategy and morphological factors associated with the success of endovascular coiling, to assess the safety and feasibility of our management strategy. From January 2003 to January 2012, we attempted endovascular coiling as the first-intention treatment for 30 consecutive patients with ruptured pericallosal artery aneurysms including those with intracerebral hematoma. Twenty-seven cases of ruptured pericallosal artery aneurysms were successfully embolized with coiling whereas three failures required surgery. Four patients experienced periprocedural complications including thromboembolic event in two and hematoma enlargement after coiling in two. A maximum aneurysm diameter of
