摘要

目的经颈静脉肝内门体分流术（TIPS）用于治疗门静脉高压并发症。门静脉穿刺通常是手术中最具挑战性和耗时的步骤。TIPS程序与延长荧光透视时间和高患者辐射暴露有关。我们测量了经腹超声引导PV穿刺对荧光透视持续时间和剂量的影响。方法我们回顾性分析了四年来在经腹部超声引导下进行的所有TIPS的辐射剂量，用于PV穿刺（n=212，其中210例成功进行，数据可用于206例）；记录荧光透视时间、剂量-面积乘积（DAP）和皮肤剂量。结果平均荧光透视时间为12分钟9秒（SD，±14分钟38秒），平均DAP为40.3±73.1 Gy·cm2，平均皮肤剂量为404.3±464.8 mGy。结论我们的结果表明，超声引导的PV穿刺导致低荧光透视时间和低辐射剂量，显著低于唯一公布的剂量参考水平。

Use of transabdominal ultrasound-guided transjugular portal vein puncture on radiation dose in transjugular intrahepatic portosystemic shunt formation.

PURPOSE Transjugular intrahepatic portosystemic shunt (TIPS) creation is used to treat portal hypertension complications. Often the most challenging and time-consuming step in the procedure is the portal vein (PV) puncture. TIPS procedures are associated with prolonged fluoroscopy time and high patient radiation exposures. We measured the impact of transabdominal ultrasound guidance for PV puncture on duration of fluoroscopy time and dose. METHODS We retrospectively analyzed the radiation dose for all TIPS performed over a four-year period with transabdominal ultrasound guidance for PV puncture (n=212, with 210 performed successfully and data available for 206); fluoroscopy time, dose area product (DAP) and skin dose were recorded. RESULTS Mean fluoroscopy time was 12 min 9 s (SD, ±14 min 38 s), mean DAP was 40.3±73.1 Gy·cm2, and mean skin dose was 404.3±464.8 mGy. CONCLUSION Our results demonstrate that ultrasound-guided PV puncture results in low fluoroscopy times and radiation doses, which are markedly lower than the only published dose reference levels.
