门静脉血栓是肝硬化的并发症,形成原因可为良性或恶性。血栓性质可对肝脏病变的治疗有明显的影响。作者报道14例肝硬化患者US引导下经皮穿刺门静脉血栓活检方法和结果。男12例,女2例。年龄43～76岁,平均59岁。其中13例证实有肝细胞肝癌(HCC)。采用Acuson型128计算声象图系统,3.5MHz探头,13例病人使用20号Crown活检针,1例用22号Chiba针。活检前用1％利多卡因局麻,无需全麻或镇静剂。8例自门静脉左支取血栓活检,6例自门静脉右支取血栓活检。
Portal vein thrombosis is a complication of liver cirrhosis. The cause of formation may be benign or malignant. Thrombosis properties can have a significant effect on the treatment of liver lesions. The authors report US-guided percutaneous needle venous thrombosis biopsy methods and results in 14 patients with cirrhosis. There were 12 males and 2 females. Age 43 to 76 years old, an average of 59 years old. Of these, 13 showed hepatocellular carcinoma (HCC). Acuson type 128 computed sound imaging system, 3.5 MHz probe, 13 patients used 20th Crown biopsy needle, and 1 case used 22# Chiba needle. Localized 1% lidocaine prior to biopsy, no need for general anesthesia or sedatives. Eight cases had a thrombus biopsy from the left branch of the portal vein, and six had a thrombus biopsy from the right branch of the portal vein.
