title: Continuous growth of remote intracerebral haematoma following angiographically successful endovascular embolisation of ruptured cerebral aneurysms.
abstract: We describe a poorly recognised and rare complication following the endovascular embolisation of ruptured cerebral aneurysms. Three patients with dense focal subarachnoid haemorrhage (SAH) developed continuous growth of remote intracerebral haematoma (ICH) following endovascular embolisation of a ruptured aneurysm. All endovascular procedures were conducted within less than 6 hours after the onset of SAH with systemic anticoagulation and were completed uneventfully; external ventricular drainage was subsequently inserted. Repeated CT scans revealed continuous growth of ICH remote from the aneurysm without aneurysmal rebleeding. The authors suggest that endovascular embolisation for a ruptured aneurysm under systemic anticoagulation within 6 hours after SAH onset may increase the risk of expanding haematomas, especially in patients with dense focal SAH.
