Abstract: PURPOSE: This study evaluated and monitored the outcome of
angiographic embolization of hepatic carcinoma by real-time C-arm angiographic
computed tomography under number of tumors, size of tumors, and patient's age. METHODS AND MARTIALS: In total, 142 patients underwent
angiographic embolization of hepatic carcinoma. The control group, 71 patients,
underwent conventional angiographic (CA) embolization of hepatic carcinoma. The
experimental group, 71 patients, underwent C-arm angiographic computed
tomography (CCT) embolization of hepatic carcinoma. The numbers of angiographic
embolization, number of tumors, size of tumors, and patients ages were recorded
for comparisons between groups by analysis of variance (ANOVA) with
cross-interaction and the chi-square test (cross table). RESULTS: The age ranges were 20–84 and 35–84 years old for the experimental
and control groups respectively. Average number of angiographic embolizations
of hepatic carcinomas were 2.63 ± 1.84 and 5.32 ± 2.01 for the
experimental and control groups. The number of angiographic embolizations under
number of tumors, size of tumors, and patients ages between groups were
significantly different (P< 0.05). The effective analyses of transcatheter
arterial chemoembolization (TACE) by CCT were significant by chi-square test
(P< 0.05) under ⩽ 3 cm and patients aged ⩽ 60. CONCLUSION: The main advantage by CCT for undergoing TACE under tumor size
smaller than 3 cm and numbers of tumor smaller 3 times were more significantly
effective than those by CA. The CCT combined with TACE had high potentially
reduced numbers of undergoing TACE.
