Predictive Model Development for Postoperative Complications in Trigeminal Neuralgia Patients Undergoing Percutaneous Balloon Compression

BACKGROUND: Trigeminal neuralgia (TN) patients undergoing percutaneous balloon compression (PBC) may experience postoperative complications, warranting the investigation of influencing factors and preventive strategies. METHODS: A retrospective analysis of 164 TN patients who underwent PBC was conducted to compare baseline characteristics and identify risk factors using LASSO regression. A multivariate logistic regression model was developed to predict complications. RESULTS: Significant differences were observed between complication and non-complication groups related to nerve branches, hypertension, compression duration, and CD4+ levels. The final model identified nerve branches, diabetes, compression duration, and CD4+ levels as independent risk factors. The model exhibited good discriminatory power (AUC = 0.793) and calibration, with meaningful clinical utility shown through DCA. CONCLUSIONS: The study established a predictive model for postoperative complications in TN patients undergoing PBC, offering a framework for preoperative risk assessment and tailored preventive interventions.
