EVALUATION OF ANGIOGRAPHICALLY ASSISTED SPIRAL CT IN SURGICAL CASES OF HEPATOCELLULAR-CARCINOMA CONSIDERING RECURRENT CASES

Between June 1993 and July 1996, computed tomography during arterial p ortgraphy (CTAP) was performed on 22 patients with hepatocellular carc inoma (HCC) and liver cirrhosis before surgery. In 17 out of 22 patien ts, CT hepatic arteriography (CTA) was combined with CTAP, All 22 pati ents underwent definitive surgery. In 16 patients in which CTA was suc cessfully performed, 20 HCC nodules and 28 pseudolesions were detected , The pseudolesions were depicted larger in size with CTA than with CT AP, formed a variety of shapes, and were enhanced homogeneously, while HCC nodules were depicted larger with CTAP than with CTA, formed a ro und or wedge shape, and were sometimes enhanced heterogeneously, Recur rence was diagnosed in 9 of 22 patients. Five recurrent lesions in 4 p atients were already revealed by pre-operative CTAP, CTA was performed in only 1 of 5 lesions. The diagnostic accuracy for HCC significantly improves by recognizing by recognizing pseudolesions with CTA and CTA P.
