Endovascular treatment of ruptured aneurysms in anterior cerebral circulation with double microcatheter technique

Abstract Purpose Single coiling may be the optimal strategy for ruptured aneurysms. But assisted techniques may be needed in some aneurysms. The authors report their experience of double microcatheter technique in the treatment of ruptured aneurysms in anterior cerebral circulation. Methods Between 2012 and 2018, 82 patients with ruptured aneurysms in anterior cerebral circulation were treated with double microcatheter technique. The clinical records, angiographic results, procedure-related complications were reviewed. Clinical and angiographic follow-up was performed. Results Completely occlusion, neck remnant and partial occlusion were achieved in 56.6%, 36.1% and 7.2% in the whole procedures, respectively. The overall rate of morbidity was 8.5% (7/82). The rate of permanent morbidity was 3.7% (3/82). Three patients (3.7%) died before discharge. There was no procedure-related mortality. The favorable outcomes were obtained in 75.6% (62/82) of the whole patients at discharge. High Hunt-Hess grade and suffering from craniotomy or EVD were risk factors for clinical outcomes at discharge. Sixty-eight patients received clinical follow-up at a mean interval of 15.75±12.71 months. Favorable outcomes were obtained in 61 (89.7%) patients. Angiographic follow-up was performed in 44 patients at an average of 13.16±13.12 months. The recurrence rate is 34.1%. Seven of them (15.9%) received retreatment. Conclusion Double microcatheter technique is a safe and effective method for treatment of ruptured aneurysms in anterior cerebral aneurysms with low morbidity. Recurrence remains a problem. Patients should be followed up regularly.
