Purpose: To compare the mid-term follow-up angiographic findings in distal internal carotid artery (ICA) aneurysms treated by stent-assisted coil embolization using the Enterprise or Neuroform stent.
Materials and Methods: We included 68 patients with 70 aneurysms: 31 cases with Enterprise and 39 cases with Neuroform. Inclusion criteria were 1) location of the stent within the distal ICA, including the carotid siphon; 2) follow-up angiogram after > 6 months, and 3) single use of the stent for 1 parent artery.
Results: The patients’ mean age was 54.9 years (16 male and 52 female). Mean follow-up duration was 9.1 months. At follow-up, there were intraluminal filling defects of the parent artery in 19.4% of the Enterprise group and no filling defect in the Neuroform group. There was no significant in-stent stenosis in either group. Straightening of the parent artery was seen in 35.5% of the Enterprise group and 20.5% of the Neuroform group. Two Enterprise cases showed delayed migration.
Conclusion: The Enterprise showed statistically significant intraluminal filling defects of the parent artery compared with the Neuroform. The rates of significant in-stent stenosis and straightening of the parent artery were not significantly different between the Enterprise and the Neuroform groups.
