Aims and objectives
To assess aneurysm occlusion level after endovascular embolization depending on coil density and aneurysm volume.
Evaluate whether the coil packing density has affect on aneurysm occlusion level.
Methods and materials
This is a retrospective study of cerebral aneurysm endovascular embolization,
performed in Riga East Clinical University Hospital,
department of interventional radiology.
Data from the procedure day and follow–up data three to six months after embolizations was gathered for patietns with the following diagnoses – cerebral ruptured and unruptured aneursysm with subarachnoid hemorrhage or sequelae of subarachnoid haemorrhage.
Patients were divided into two groups – patients with ruptured aneurysms and with unruptured aneurysms.
Total coil volume for each aneursym was calculated considering the amount of coil...
Results
128 patients were included in this study,
with age ranging from 27 to 83 years,
with the mean age (±SD) of 57,7 (±14,4) years.
10 patients have had more than one procedure with total number of aneurysms studied – 143.
Most common of material types that were used in cerebral aneurysm embolization in both groups are seen in Figure 5.
Number of patients in the rupture group was 99 (with a total of 99 aneurysms) – 59 women (59,6%) and 40 men (40,4%) with the...
Conclusion
Aneurysms both occur and rupture more often in women.
Most common localization of ruptured aneurysms was anterior communicating artery and in unruptured aneurysm group – middle cerebral artery.
Stable occlusion of aneurysms with unchanged or improved degree of occlusion after three to six months after procedure was observed in 84,5% of ruptured aneurysm cases and 92% of unruptured cases.
There was no statistically significant correlation found between coil packing density and degree of occlusion.
