Endovascular cerebral aneurysm treatment: Long term outcomes
Abstract
Methods
We retrospectively assessed the follow-up angiograms of patients, who presented with subarachnoid haemorrhages or IIIrd nerve palsies and had berry aneurysms treated endovascularly between 2002 and 2003, Patients were phoned to assess their wellbeing and to see whether they were back at work or not.
Angiograms were assessed to ascertain percentage of aneurysm coiled at initial procedure and then stability was assessed by percentage change in the residual on later angiograms.
Results
Over a 1-year period 75 patients were treated endovascularly. 100% occlusion was attainable in 52% at the initial procedure and although the number of patients who attended their 3-month and 1year follow-up angiograms were 40 and 34 respectively there was a trend toward progressive thrombosis to 65% and then 82% respectively. In only 1 of the neck remnants was there growth at the 3-month angiogram. One patient bled having missed his 3-month follow-up angiogram. Although only 40% of the patients were contactable at 4 years there was no re-bleeds amongst them.
Conclusion
Coiling is durable as shown by our results over a 4 year period and while neck remnants may be observed any growth should be viewed as unstable and treated either endovascularly or surgically if required.
