Abstract

|
To evaluate the effectiveness of superselective transcatheter arterial embolization (STAE) for hepatocelluar carcinoma (HCC) with a mixture of ethanol and Lipiodol, STAE was done in 12 male patients with HCC. Three were diagnosed clinically with
angiographic findings and elevated alphafetprotein levels and three were recurrent tumors after surgery. Sono-guided aspiration biopsy proved the diagnosis of hepatocellular carcinoma in another six patients. The tumor was a small single nodule
(2-5cm
in diameter) in 11 patients. In one patient, two nodules were found. Superselective catheterization was done using 3F Tracker catheter(Target Therapeutics USA) coaxially through 6F catheter into the feeding hepatic artery, usually the third order
branch. One to four cc of 75% ethanol mixed with Lipiodol was infused under fluoroscopy immediately after imjection of 2% lidocaine. Immediate angiography and CT after 2 weeks were undertaken. Complete segmental or subsegmental devascularization
including feeding arteries and tumor vascularities occurred in all patients. Follow-up angiography after 6 to 15 months revealed the tumor opacified by Lipiodol. The tumor decreased in 5 cases and recurrence was found in three patients. CT taken
2
weeks
after STAE showed low density halo around the tumor in 5 cases. Subsequest segmentectomy in four patients revealed total or near total necrosis of the tumor and no evidence of damage in surrounding parenchyme.
STAE for HCC with a mixture of ethanol and Lipiodol is an effective and safe measure for small HCC.
