Microsurgical treatment of cerebral aneurysms after endovascular treatment (systematic review of the literature). Part 2

To conduct a systematic review of the literature on microsurgical treatment of recurrent and residual aneurysms after unsuccessful endovascular treatment, determine the surgical technique features depending on the cause of aneurysm recurrence, localization, size, and shape of the aneurysm, and analyze treatment outcomes, including radical exclusion, complication rates, and clinical outcomes. Despite technical difficulties, microsurgical treatment of residual and recurrent aneurysms is a safe and effective method in most cases, with only a small number of patients requiring unconventional techniques such as coil removal, thrombectomy, or deconstructive procedures combined with revascularization. Aggressive treatment is recommended in all cases where long-term angiographic follow-up shows an increasing residual or recurrent aneurysm.
