【Abstract】Objective To investigate the diagnostic and therapeutic value of selective angiography and embolization treatment in massive biliary hemorrhage in emergency. Methods Eleven cases of massive biliary bleeding were selectively angiographied and embolized with thread segment and gelatin sponge grain by Seldinger technique in emergency. Results Massive biliary bleeding in this series included bleeding after biliary surgery (7), post-laparoscopic cholecystectomy bleeding (1), bleeding from traumatic injury to liver (1), and rupture of huge hepatic cancer (2). There were 9 cases with abnormal angiographic findings including contrast medium leakage (9), tumor vessels and tumor tissue staining (2) and signs of pseudo-aneurysm formation (4). All the bleedings were stopped after emergency intervention but 2 cases with recurrent massive bleeding after 48 hours. Conclusion Emergency trans-catheter embolization treatment is an effective and safe method for biliary massive hemorrhage. It is also important to keep the biliary tract unobstructed.
Objective To evaluate the efficacy of transcatheter arterial chemoembolization (TACE) combined with radiofrequency ablation (RFA) in treating primary hepatocellular carcinoma (HCC). Methods From March 2004 to March 2006, 137 patients with primary HCC underwent TACE alone (n=87) and TACE+RFA (n=50), respectively, after the interventional treatment, all patients periodically received CT reexaminations and alpha fetoprotein (AFP) measurement. The therapeutic efficacy, AFP level and survival rate between two groups were compared with each other. Results In TACE group the effective rate (CR+PR) was 34.5%, AFP decreasing amplitude was 54.2%, and 2 years survival rate was 43.7%. While in TACE+RFA group, the effective rate (CR+PR) was 70.0%, AFP decreasing amplitude was 78.0%, and 2 years survival rate was 62.0%, there were significant differences between two groups (P＜0.05). Conclusion Combined application of TACE and RFA is significantly superior to TACE alone in treatment of primary HCC.
