This clinical study aims to investigate adverse outcomes following percutaneous balloon compression (PBC) of the trigeminal ganglion, establish a predictive model, and assess the probability of postoperative complications.The main question it aims to answer is: 1. What factors are associated with adverse postoperative outcomes? 2. What is the occurrence probability of different types of adverse outcomes? The study will record patients' demographic and clinical characteristics, laboratory test results, and conduct follow-ups at 3, 6, and 12 months postoperatively.
