To investigate the safety and effectiveness of endovascular treatment for anterior cerebral artery (ACA) dissecting aneurysms. We retrospectively analyzed the clinical data of 11 patients with ACA dissecting aneurysms admitted to the Second Affiliated Hospital of Guangxi Medical University from January 2017 to December 2023. The clinical characteristics, aneurysm morphological features, treatment effects, and follow-up results of the two groups were analyzed. Three patients received Tubridge flow diverter (TFD group), and 8 patients underwent stent-assisted coil embolization (SAC group). The results showed that the mean age of the TFD group (43.67 ± 2.31 years) was lower than the SAC group (59.00 ± 8.28 years) (P = 0.012). In the SAC group, 75% of patients initially presented with subarachnoid hemorrhage(SAH), whereas there were no cases of SAH in the TFD group (P = 0.034). During follow-up, no aneurysm recurrence was observed in either group. In the SAC group, one patient (12.5%) experienced the complication of cerebral infarction. In conclusion, both flow diverters and SAC are safe and effective treatments for ACA dissecting aneurysms. SAC may be more suitable for saccular aneurysms with acute hemorrhage, while flow diverters may be a better option for fusiform aneurysms. Aneurysm morphology may be an important consideration in treatment selection.
