[Angiographic findings of gallbladder cancer].

The patients with gallbladder cancer often accompany with chronic cholecystitis. This fact leads angiographic diagnosis difficult. So the angiographic findings of the chronic cholecystitis are first analyzed precisely and subtracting the angiographic findings of the gallbladder cancer from these gives us the pure (true) angiographic findings of the gallbladder cancer. Characteristic angiographic findings of the gallbladder cancer only are stretched cystic artery encasement (27/37 cases) and short straight tumor vessels "bristly vessel" (36/37 cases).
