Endovascular treatment of anterior communicating artery aneurysms: results of clinical and radiological outcome in Newcastle.
The results of endovascular management of anterior communicating artery aneurysms (ACoAA) using Guglielmi Detachable Coils (GDC) are presented. We detail the clinical and radiological features, and postoperative clinical and radiological outcome in a consecutive series of patients. We have prospectively collected comprehensive data on our patients with SAH since 1989. This study reports on patients admitted between January 1990 and December 1998, and focuses on 30 patients who had their ACoAA endovascularly treated. An independent observer (TE) carried out long-term follow-up in January 2002. Statistical analysis was performed to study the relationship between clinical factors, the radiological morphology of aneurysms and the long-term outcome. The age ranged from 25 to 74 years (median: 54) and endovascularly treated ACoAA were more common in women, 19 (63%) compared with men, 11 (37%). Seventy-seven per cent were in good grade (WFNS 1 & 2) before treatment. Three patients rebled before treatment. The aneurysms were less than 10 mm in maximal diameter in 27/30 patients. The follow-up period was from 1 to 53 months (mean 32.5, median 36.6 months). Excellent outcome was recorded for 11 patients (36.7%), good in seven patients (23.3%), fair in three patients (10%) and poor in four cases (13.3%). Five patients had died (mortality 16.7%). Favourable outcome was achieved in younger patients, women, and in those who presented in grades 1 and 2. The long-term radiological follow-up revealed residual necks in 13 patients. Only one has required retreatment and no rebleed has occurred in 3-6 years. This study reports a contemporary experience with the endovascular management of ACoAA. Long-term stability of the coil and good outcome is demonstrated. Endovascular treatment using GDC is an efficient technique for treating acutely ruptured ACoAA with little additional morbidity. The clinical and radiological results are comparable with those in the literature.
