Objective To study clinical value of a new therapy for tumor thrombus of portal vein.Methods Twenty patients received direct puncture to portal vein or tube insertion under ultrasonographic guide.Among them,16 patients received direct injection and 4 had tube insertion.It provided high concentration of anticancer drugs directly to the tumor thrombus.Results The thrombus disappeared only one case,the mass of tumor thrombus decreased in the portal vein trunk in 3 cases and obviously was controlled in 6 cases.The survival time in the group with treatment was longer than in that the control group.Conclusion This method is an effective,safe and easy procedure,it has active significance for advanced hepatic cancer.

Objective To explore the safe technique of caudate lobectomy for liver cancer in candafe lobe(LCCL).Methods The clinical data of 11 cases of primary liver cancer in caudate lobe who received hepatectomy successfully were retrospectively analyzed. four procedures were used in the operations:(1)selection of appropriate skin incision, so as to obtain excellent exposure of operative field;(2)adequate mobilization of the liver to allow the liver to be displaced upwards to the left or to the right;(3)preparatory placement of tapes for total hepatic vascular isolation,so that this procedure can be used when necessary;(4)selection of the ideal route for hepatectomy based on the condition of the tumor and, if necessary, the combined removal of multiple lobes. Among the 11 cases, simple occlusion of vessels of porta hepatis was used for candate lobectomy in 6 cases, while, in the other cases, the vessels were intermittently occluded several times or total hepatic vlascular isolation was used for the caudate lobectomy. combined partial right hepatectomy was done in 2 cases, combined left lateral lobectomy in 3 cases and caudate lobectomy alone in 6 cases.Results Operation was smooth and successful in all of the 11 cases, and there was no mortality. Conclusions Caudate lobectomy for LCCL can be safely performed when the above procedures are used.
