术中超声在冷循环射频治疗肝脏肿瘤中的作用

目的:探讨术中超声在冷循环射频治疗肝脏肿瘤中的应用价值。材料和方法:对31例肝癌患者在开腹手术时行术中超声检查,并以超声作为射频针穿刺的引导手段,动态观察手术进程。结果:31例患者均在术中超声引导下完成治疗。其中7例术前未发现小病灶。1例排除术前MR I诊断的1处假阳性病灶。结论:术中超声可发现术前影像学检查遗漏的小病灶,避免胆管、血管损伤等并发症,实时观察射频治疗过程并优化手术策略。

Application of Intraoperative Ultrasonography in the Cool-tip Radio-frequency Ablation of Hepatic Carcinoma

Purpose: The feasibility and efficacy of intraoperative ultrasonography(IOUS) in the cool-tip radio-frequency ablation(RFA) of hepatic carcinoma was evaluated.Materials and Methods: 31 patients of hepatic carcinoma were enrolled in this study.In the process of opensurgical cool-tip radio-frequency ablations,intraoperative ultrasonography was applied to assess the hepatic lesions,to guide and to monitor the process of RFA in real-time.Results: Under the guidance of intraoperative ultrasonography,the open surgical RFA in all patients proceed smoothly.Seven additional hepatic masses were found that were not detected in preoperative imaging.A false positive focal lesion reported by preoperative MRI was accurately ruled out by IOUS.Conclusion: Intraoperative ultrasonography is superior to ordinary imaging techniques in finding missed lesions,avoiding complications such as injuries of bile ducts and vessels,and in monitoring in real-time the RFA process thereby obviously optimizing the treatment of hepatic carcinoma.
