[Types of arterio-portal fistula of hepatocellular carcinoma patients on helical computed tomography and digital subtraction angiography].

OBJECTIVE

To analyse the pathogenesis of the hepatocellular carcinoma (HCC) with arterio-portal fistula (APF) and the types of these APF on helical CT (HCT) and digital subtraction angiography (DSA), and to study the interventional therapy for HCC patients with APF.

METHODS

HCC with APF in 48 patients were reported. All the patients received contrast media enhanced HCT scan and DSA examination. The APF were divided into the peripheral type, the hepatic segment type, and the center type according to the findings on HCT and DSA.

RESULTS

The peripheral type of APF were found in 14 cases (14/48), the hepatic segment type in 15 cases (15/48), and the center type in 19 cases (19/48) on HCT scan, respectively. The peripheral type of APF were found in 13 cases (13/48), the hepatic segment type in 16 cases (16/48), and the center type in 19 cases (19/48) on DSA examination, respectively. The pertinency and consistency on the types of APF between HCT and DSA were compared, and the consistency rate was 85.42%; Kappa=0.779, u=7.60, P<0.01. It showed high pertinency of the types of APF between HCT and DSA. The center type APF in 11 of 19 cases disappeared, in 6 of the 19 cases partly disappeared, in 1 case was noneffective, and in 1 case was reformulation after the interventional therapy. The segment and peripheral types of APF in 20 of the 29 cases disappeared, in 8 of the 29 cases partly disappeared, and 1 case was noneffective after interventional therapy.

CONCLUSION

It's vital to know well the features of various types of APF in HCC on HCT and DSA, which can bring about positive effect on interventional therapy for HCC with APF.
