Interventional embolization of intracranial aneurysms is now widely available. However, recurrence of aneurysm after embolization is not uncommon. For recurrent aneurysms after embolization that cannot be embolized again or cannot achieve stable occlusion with re-embolization, as well as for aneurysms that have been embolized early to avoid rebleeding during the acute phase of hemorrhage and await second-stage surgical clamping, cranial clamping should be considered. However, the surgical technique of second-stage clamping is more challenging than that of first-stage clamping. OndraPetr et al. of the Department of Neurosurgery, Mayo Medical Center, Rochester, USA, performed a systematic evaluation of the safety and efficacy of second-stage clamping of recurrent aneurysms after embolization, and the results were published in the October 2015 issue of ActaNeurochir. In summary, the study concluded that reoperative clamping is safe and effective for recurrent aneurysms after embolization; the prognosis of patients with recurrent aneurysms is better with direct clamping than with “clamping and removal of the spring coil” and “blocking the aneurysm-carrying artery”; Delayed surgery, i.e., clamping after 4 weeks of embolization, was more effective than early surgery; the complications and mortality rates of second-stage surgical clamping of recurrent aneurysms in the posterior circulation were higher than those of patients with anterior circulation aneurysms. This study was limited to a case-series evaluation, and the results need to be confirmed in a larger sample of randomized controlled clinical trials.
