Evalution of ultraselective transcatheter tumor feeding arterial embolization with ethanol and lipidol for small hepatocellular carcinoma (SHCC) in 95 cases

Objective:To retrospectively evaluate the safety,technical success rate,and effectiveness of ultratranscatheter tumor feeding arterial embolization with ethanol and lipidol for SHCC,and to explore the new therapy for SHCC. Methods:To 95 cases carry out hepatic selective arterial angiography for SHCC by CT or MRI be diagnosed and clinical very doubt be SHCC,after was diagnosed by DSA,to transcatheter ultraselective subsegmental feeding artery with microcatheter for tumor,employ ethanol and lipidol (1/1) to full fill embolized 143 tumors. Results:Technical success rate was 100% for the ultraselective subsegmental feeding artery transcatheter and embolizatoin in SHCC,There were no major complications in all cases.Before embolization ,the diameter of tumors were 0.5~3cm,average diameter 2.3 cm. after tumors were embolized,average diameter 1.2 cm. The 1,3and 5 year recurrence rates were 19%(18/95),27%(26/95),37%(35/95),and the survival rates were 100%(95/95),85%(81/95),67%(64/95) respectively. Conclusion:Its effectiveness was very notable,there were no major complications and recurrence rates was less than surgical resection in ultraselective transcatheter tumor feeding arterial embolization with ethanol and lipidol for SHCC,It should become the first selective therapy for SHCC.
