As mentioned earlier, there is a recurrence rate after cerebral aneurysm intervention. The mechanism of recurrence is that the impact of blood flow compresses the spring coil mass in the aneurysm cavity to the bottom of the aneurysm and reopens the neck of the aneurysm. The purpose of regular review is also to detect and treat recurrent aneurysms at an early stage. Recurrent aneurysms can still be re-intervened, and open clamping can also be considered if re-intervention is difficult. A number of clinical studies have shown that stent-assisted techniques can significantly reduce the long-term recurrence rate after cerebral aneurysm interventions, so stent-assisted treatment is routinely recommended for re-intervention of recurrent aneurysms. In recurrent cases where a stent was used in the first intervention, a second stent can still be placed overlappingly during reintervention to enhance flow guidance and promote intimal repair.
