经皮脾穿刺CO2门静脉造影与动脉法间接门静脉造影的对照研究

目的 对经皮脾穿刺CO2门静脉造影与动脉法间接门静脉造影进行对照研究，评价其造影效果及临床应用价值。方法 21例患者（男16例，女5例），原发性肝癌15例，转移性肝癌6例。分别同时行肠系膜上动脉间接门静脉造影和经皮脾穿刺CO2门静脉造影，对造影结果进行统计学分析，并对经皮脾穿刺CO2门静脉造影的安全性进行评估。结果 21例经皮脾穿刺CO2门静脉造影中20例造影成功，图像质量明显优于动脉间接法门静脉造影（t=6．815，P〈0．01）。木中有10例患者（10／21）CO2造影术中有一过性轻度腹部不适，1例术后脾脏出血。结论 经皮细针穿刺脾脏CO2造影可清晰显示门静脉结构，图像质量优于动脉法间接门静脉造影，造影方法简便、创伤小、经济；熟练的操作可以提高其安全性。

Percutaneous transplenic CO2 splenoportography: comparasion with arterial portography

Objective To evaluate the safety, efficacy and clinical feasibility of percutaneous transplenic CO_2 splenoportography with fine-needle. Methods Percutaneous transplenic CO_2 splenoportography and arterial portography were performed simultaneously in 21 patients (15 primary hepatic carcinoma , 6 hepatic metastatic cancer) . With ultrasound or fluoroscopy guidance, 26 G super fine-needle were employed in percutaneous transplenic CO_2 splenoportography. Paired-samples t-test was used to analyse the results. Results Twenty cases had excellent images. Compared with arterial portography, significant difference was observed. Ten cases were well tolerant in the course of CO_2 splenoportography , while other 10 patients had mild moderate abdominal discomfort. One patient had splenic haemorrhage after splenic puncture. Conclusion The percutaneous transplenic CO_2 splenoportography with super fine needle demonstrate optimal portography, which seemed to be less time-consuming, minimally invasive, economic and easy to perform. The experienced interventional radiologist may increase the safety to perform this procedure.
