Patient: Previously had craniotomy in Fuzhou Union Hospital, but the surgery did not work, and then recurred. Please ask Professor Zhang how to treat it again. If the aneurysm has recurred, it is more difficult to treat it again, but it is not impossible to treat it. Whether and when to treat the aneurysm depends on the cause of the recurrence, the size, shape and location of the recurrent aneurysm, and the risk of re-rupture or the risk of re-treatment to the patient. Treatment options include reoperation or interventional treatment. My question is how many years since the patient’s cerebral aneurysm clamping? When was the cerebral angiogram performed to confirm a recurrence? What are the patient’s current symptoms? Please upload the imaging data, if available, in order to help you analyze how to choose a treatment option. In fact, for such an important issue as re-treatment, especially the choice of treatment and timing, it is better to come to Beijing with the information for an in-person consultation and face-to-face communication.
