The objective of this study was to analyse the technical and clinical outcome in elderly patients receiving endovascular treatment for acutely ruptured intracranial aneurysms. The case notes and angiograms of 14 patients over the age of 69 years undergoing endovascular treatment for subarachnoid haemorrhage within the Interventional Neuroradiology Unit, Royal Perth Hospital over a period of 6 years were retrospectively reviewed. The degree of angiographic occlusion achieved, and periprocedural, short-term and long-term clinical outcome were retrospectively assessed. Greater than 90% occlusion was obtained in 92% of cases. 82% of patients with Hunt and Hess grade I and II had an excellent clinical outcome. We conclude that endovascular coiling is an effective means of treating acute subarachnoid haemorrhage in grade I and II elderly patients. [ABSTRACT FROM AUTHOR]

The objective of this paper was to analyse the technical and clinical outcome in patients receiving endovascular treatment for posterior circulation intracranial aneurysms at Royal Perth Hospital. The case notes and angiograms of 35 patients with ruptured and unruptured posterior circulation aneurysms treated by endovascular coil occlusion between 1992 and 1998 were included in the study. The degree of angiographic occlusion achieved, and periprocedural, short and long-term clinical outcome were retrospectively analysed. Total aneurysm occlusion was achieved at initial treatment in 46% of cases, with 90% or greater occlusion achieved in 97% of cases. For aneurysms 12 mm or less in diameter, 100% of patients treated electively, and 100% of patients with grade I or II subarachnoid haemorrhage treated in the acute postictal phase had a good clinical outcome (Rankin Disability Score 1 and 2), with no serious morbidity or associated mortality. Excluding patients with grade V subarachnoid haemorrhage, the treatment-related serious morbidity rate was 3.4% and procedurerelated mortality rate was 0%. We conclude that endovascular management provides an effective means of treatment for selected cases of posterior circulation aneurysms. [ABSTRACT FROM AUTHOR]
