Staining in the liver surrounding gallbladder fossa on hepatic arteriography caused by increased cystic venous drainage

Abstract

In 8 patients with gallbladder disease in whom no extension of the disease to the liver was confirmed by surgery, wedge-shaped (segmental) staining of the liver just adjacent to the gallbladder fossa (gallbladder bed) on hepatic arteriography was seen. This was always accompanied by definite visualization of the cystic veins with the drainage directed to the gallbladder bed and became most dense following the peak of the opacification of the cystic veins. We therefore concluded that the increased cystic venous drainage to the intrahepatic portal vein causes the staining in the nondiseased gallbladder bed on hepatic arteriography.

Efficacy of SPIO-MR Imaging in the Diagnosis of Liver Metastases from Colorectal Carcinomas

“…In our study, four false-positive lesions, which all were found to be pseudolesions rather than nonmetastatic space-occupying lesions, were found in 3 patients, yielding a false-positive rate of 8.5%. The four pseudolesions on CTAP/CTHA included such due to aberrant gastric venous drainage and increased cystic venous drainage which have been reported in other studies [14, 15]. Metastases can sometimes be excluded depending on the location and the shape of pseudolesions seen on CTAP/CTHA.…”

“…We diagnosed lesions that showed perfusion defects in CTAP and tumor stains in CTHA as metastases. It has been reported that pseudotumors are often seen in segment IV of the liver and in the area surrounding the gallbladder fossa on CTAP/CTHA [14, 15]. In this study, we arbitrarily diagnosed lesions in these areas that were possibly pseudotumors as metastases.…”

Hepatic perfusion abnormalities in acute pancreatitis: CT appearance and clinical importance

“…Matsui et al [11] reported that, based on angiographic findings, the increased cystic venous drainage into the intrahepatic portal vein in the gallbladder bed was considered to be the cause of staining seen in the nondiseased gallbladder bed. In our study, the inflamed gallbladders were histopathologically confirmed in four patients.…”

Radiologic manifestation of hepatic pseudolesions and pseudotumors in the third inflow area

“…Areas in the liver drained by cystic veins occasionally appear as hypo-attenuating areas on CTAP because the contrast medium in the portal blood from the superior mesenteric vein is diluted by blood from cystic veins, which does not contain contrast medium [7].…”

“…In 1987, Matsui et al [7] reported that the increased cystic venous drainage to the intrahepatic portal vein causes staining in the non-diseased gallbladder bed on hepatic arteriography.…”
