Abstract
© 2018, Faculty of Medicine Siriraj Hospital, Mahidol University. Objective: Development of extrahepatic collateral arteries (ECAs) supply to hepatocellular carcinoma (HCC) can interfere efective control of tumor by transcatheter arterial chemoembolization (TACE) treatment. he aim of this study is to analyze the prevalence and causative factors of ECAs to HCC and complications of TACE through each ECAs. Methods: We performed a retrospective review of total 1,374 procedures from 639 patients with a diagnosis of HCC who were sent for TACE (range from 1 -16 sessions, mean = 2.87 sessions) from January 2008 -May 2010. Prevalence, causative factors such as size and location of the tumor and previous treatment were analyzed. Results: here are 122 (19.09%) from 639 patients that showed ECAs supplying the tumors. he prevalence of ECAs to HCC was 34.39% from right inferior phrenic artery, 30.68% from omental artery, 9.52% from let gastric artery, 5.82% from let inferior phrenic artery, 5.29% from colic branch of superior mesenteric artery (SMA) and 4.23% from intercostal artery. Statistical analysis showed that tumor size of more than 8-10 cm and location at hepatic surface, especially liver bare area were signiicantly associated with the presence of ECAs (p<0.01). he cumulative probability of ECAs formation increases with a number of the sessions of TACE. Conclusion: Our observation indicates that the factors which could inluence ECAs formation included tumor size of more than 8-10 cm and tumor location at surface area, especially liver bare area. As the number of TACE sessions increased, the cumulative probability of the presence of ECAs also increased. TACE through the ECAs is a relatively safe procedure. To recognize and get familiar with the presence of ECAs to HCC are essential to improve treatment outcome of the patients.
