Superselective transcatheter arterial chemoembolisation of an unresectable hepatocellular carcinoma using three-dimensional rotational angiography

Department of Radiology, Showa General Hospital, 2-450 Tenjincho, Kodaira, Tokyo, 187-0004, Japan

View larger version (68K): [in this window] [in a new window]   Figure 1. (a) Angiogram of the lateral branch of the left hepatic artery shows a hypervascular tumour in segment III of the liver. It is difficult to determine which of several overlapping branches is actually supplying the tumour. (b) Three-dimensional (3D) rotational angiograms of the lateral branch of the left hepatic artery show a branch artery (arrowheads) closely related to the tumour (arrows), which was considered the feeding artery of the tumour. The feeding artery arises from the segment III artery and runs backward and to the right. The other branch arteries are separate from the tumour. (c) Superselective angiogram of the feeding artery shows the blush of the entire tumour. (d) Post-embolisation angiogram shows no visualization of the tumour. (e) Unenhanced CT scan obtained 1 month later shows dense deposition of iodized oil in the entire tumour.
