[Differential diagnosis of gallbladder diseases by superselective angiography of the cystic artery].
To clarify differential points of angiographic findings, cystic angiograms of 46 patients with various gallbladder diseases were studied. In cases of gallbladder carcinoma, the angiographic findings differed in degree of the depth of cancer invasion and the shape of tumor. Abnormal findings in arterial phase were seen even in some cases of early carcinoma and tumor stains were clearly seen in all cases except for cases of superficial type of early carcinoma. In cases of cholecystitis, the findings on the degree of inflammation and wall thickening of the gallbladder varied. It was important for differential diagnosis between carcinoma and inflammation of the gallbladder to fully understand reciprocal relation of arterial and venous phase of the cystic angiogram. In cases of adenomyomatosis of the gallbladder, dilatation and tortuosity of the branches of the cystic artery and an increase of vascularity in the thickened wall were characteristic. Faint tumor stains were seen in some cases of cholesterol polyps of the gallbladder, which indicates that malignancy should not be diagnosed based only on the presence of such stains.
