RESUMO
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.
RESUMO
Objective To evaluate the efficacy of the renal arterial embolization with lipidol and absolute alcohol emulsion in the treatment of renal tumors. Methods The superselective renal arterial embolization by using coaxial-cathaterization with infusion of lipiodol and absolute alcohol (in proportion of 2 ∶ 1) emulsion was performed in twenty patients with malignant and benign kidney tumors. 4 weeks later, the renal arteriography was taken routinely and repeated embolization was performed in case of necessary; and follow up was carried out periodically. Results The imaging findings showed thorough tumor necrosis and feeding vessel abruption in 18 cases after one session of treatment. The volume of tumors decreased more than a half in 13 patients (82.25%, 13 / 18) associated with a well-distributed lipidol inside the tumors. The second session of treatment was performed in other 2 patients and the clinical symptoms relieved obviously. Conclusions The superselective renal artery embolization with lipidol and absolute alcohol emulsion can permanently embolize all tumor feeding arteries in capillary vessel level with maximum reservation of renal function, providing definitively efficacy and worthwhile to be recommended widely.
