  "abstract": "Introduction Wide-neck intracranial aneurysms need additional devices like balloons or stent for management. Balloon-assisted coil embolisation (BACE) has evolved both with interventionalist experience and device modifications.Aim of study We report our experience, evolution, and complications with in performing BACE among the bifurcation and side wall aneurysms.Method Data of 2015–2022 was retrospectively reviewed. 205 aneurysms were detected in 188 patients, of which BACE was planned for 198 aneurysms. Both single and double-lumen balloons were used. Aneurysms were divided into bifurcation and sidewall aneurysms. The complications were compared between bifurcation and sidewall aneurysms, and between single and double lumen balloons.Abstract A88 Figure 1Results Balloon-assisted coiling was successfully done for 195 cases. Single-lumen balloons were used in 56 aneurysms (28.3%), and double-lumen balloons in 142 cases (71.7%). Procedural thromboembolism within parent vessel was seen in 28 cases (14.1%); however symptomatic were encountered in 5 cases (2.5%). Intraprocedural rupture of the aneurysmal sac was seen in 9 cases (4.5%). The procedure-related mortality in our series was 1.6%, and morbidity 4.3%. The complications among bifurcation and sidewall aneurysms compared showed a greater number of symptomatic thromboembolic complications in sidewall aneurysms with the use of single lumen balloons.Abstract A88 Figure 2Conclusion The balloon assisted coil embolisation has many advantages compared to the conventional coil embolisation, especially in wide neck aneurysms. There are significant symptomatic thromboembolic complications in sidewall aneurysms with the use of single-lumen balloons which decreased as interventionalist experience evolved and better hardware developed.Conflict of Interest No",
