1Russian Scientific Research Institute of Neurosurgery named after Professor A.L. Polenov - Branch of the Almazov National Medical Research Centre of the Ministry of Health of the Russian Federation, 191014, Saint Petersburg, Russian Federation.
Background:
The dual-catheter technique of aneurysm coil embolization, as well as balloonassistance are procedures making it possible to exclude wide-neck aneurysms from the blood flow.
Objective:
The aim of this work was to compare angiographic results and clinical outcomes in patients with cerebral aneurysms treated by either the double-catheter technique or balloon-assisted coil embolization.
Patients And Methods:
The study included a total of 184 patients presenting with cerebral aneurysms and operated on in the period 2019-2023 at the Russian Scientific Research Institute of Neurosurgery named after A.L. Professor Polenov. Of these, 58 patients underwent the balloon-assisted procedure and 126 were subjected to the double-catheter technique.
Results:
A statistically significant difference between the methods was revealed by the angiographic results in both the immediate and remote periods, with no difference revealed by the clinical outcome.
Conclusion:
Mastery of the dual-catheter technique allows the surgeon to disconnect wide-necked aneurysms from the blood flow, as well as to reliably protect the arterial branches incorporated into the aneurysm without worsening the functional outcome.
