Abstract:
Objective To evaluate the embolization efficiency,short term clinical effect and adverse reactions of trisacryl gelatin microspheres in interventional treatment of hepatic carcinoma. Methods Twenty three cases of hepatic carcinoma (34 foci)were given 0.5-6 ml of microspheres mixed with some contrast medium via catheter after injection of chemodrugs and lipiodol 3-5 ml; and simultaneously observing the appearance of slow down of blood flow and vascular cast formation to stop the procedure. Enhanced CT or MR and AFP were performed every 1 month after the first procedure. Treatment needed to be repeated whenever the foci or new ones were enhanced in CT scans or increase of AFP value. The clinical effect and adverse reactions were also observed. Results The positive response rate was 39.1% (CR+PR). There were 9 cases of PR,13 cases of NC and 1 of PD; but no case of CR. Residual enhancement was observed in 17 foci after first procedure,10 of which received repeated therapy and 3 were embolized completely. The other 11 foci were completely embolized,among them 4 had new residual enhancement during 4-9 mo follow up and 2 were re-embolized completely. Eighteen cases with positive AFP showed obvious decrease in 11,no change in 6 and increase in one. Eighteen cases of pyrexia,11 cases of pain in hepatic region and 6 cases of nausea occurred 5-14 d after the procedure together with vomiting. We also found increase of ALT in 2 cases,BIL of 1 case,and no change of WBC in all cases. Conclusion Trisacryl gelatin microspheres is an excellent embolization agent with better clinical effect and less adverse reaction in the treatment of hepatic carcinoma.
