MATERIAL and METHODS: We treated 66 aneurysms in 43 patients with aneurysms less than 5 mm. Of the patients, 29 were females and 14 males (mean age: 50.2 years). Headache was the most frequent symptom. In 8 patients, the aneurysms were recanalized and these had been treated with coils or stent-assisted coiling. All aneurysms were in the anterior circulation. In the treatment, one of the SILK, Pipeline, Derivo or FRED FD stents was used for each patient. Neurointerventional stent medication (double antiplatelet) was used. All patients were investigated for new ischemic lesions with diffusion-weighted imaging one day later. The first follow-up angiogram was planned 3-6 months later.
RESULTS: The treatment was technically successful in all patients. Minor complications occurred in 3 patients (7%). In one patient, thrombus inside the SILK was seen and was relieved with tirofiban. The second patient bled from the right common femoral artery entrance, which was operated on. In the third patient, the complication was technical. All patients were discharged without any neurological deficit. The mean follow-up period was 26 (6-52) months. Of the aneurysms, 64 (97.0%) were completely closed.
CONCLUSION: The FD treatment of cerebral, anterior circulation small aneurysms less than 5 mm is effective and safe.
