Abstract
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.
