Endovascular treatment of patients with cerebral aneurysms at the Regional Vascular Center of Petrozavodsk

Aim. To evaluate experience of using endovascular techniques for treatment of patients with cerebral aneurysms (their efficacy and safety) at the Regional Vascular Center of Petrozavodsk. Materials and methods. Results of treatment of patients who underwent surgery at the Neurosurgery Division of the Republican Hospital named after V.A. Baranov (Petrozavodsk) between May 2015 and December 31st 2022 were analyzed. Results. Endovascular techniques were used in treatment of 131 patients, 141 surgeries were performed. The most common was endovascular occlusion of the aneurysm sac with coils – 110 (78 %) surgeries; additionally, assisting techniques were used in 21 (14.9 %) surgeries, flow-redirecting devices were installed in 7 (5 %) surgeries, in 3 (2.1 %) surgeries aneurysm occlusion was attempted. In the majority of cases complete occlusion of the aneurysm was achieved (class I per the Raymond–Roy Occlusion Classification (RROC)): 70.2 % of patients; subtotal occlusion (class II per RROC) was achieved in 25 (19.1 %) patients, partial (class III per RROC) in 11 (8.4 %). Intraoperative complications developed in 11.4 % of cases. Clinically good treatment outcome (score 4–5 per the Glasgow scale) was achieved in 102 (77.8 %) patients, unsatisfactory result (score 1 per the Glasgow scale) was observed in 20 (15.3 %) patients. Conclusion. In patients with cerebral aneurysms who underwent surgery using endovascular techniques at the Regional Vascular Center of Petrozavodsk generally favorable clinical outcomes were achieved.
