Analysis of risk factors for intra-cystic hemorrhage in microwave ablation of partially cystic thyroid nodules

Objective The aim of this study is to identify risk factors intra-cystic hemorrhage in microwave ablation mixed solid and cystic s, design a preoperative nomogram predict the value intraoperative bleeding with goal individualizing surgical approach toward different types thyroid nodules. Methods A total 241 patients cystic-solid nodules who underwent ultrasound-guided percutaneous were retrospectively divided into group non-bleeding compare diameter, proportion, fluid nature, color Doppler flow imaging, Contrast-enhanced ultrasound (CEUS) findings, operative methods. Based on univariate multivariate analysis, important nodular intracapsular procedure projected for predicting possibility Results Intra-cystic was developed 37 cases during incidence 15% (37/241). Significant differences found statistically between two groups diameter lesions, CEUS ratio, methods ( P = 0.000, 0.001, 0.024, 0.002). predicted by model based accuracy 81% prediction consistency index (C-index) 0.78. Conclusion new efficient identified nodules, which will aid development targeted planning thus reducing ablation.
