Portal vein embolization for arterio-portal shunt closure in hepatocellular carcinoma to facilitate selective internal radiation therapy

Figure 1 Arterio-portal shunt detection on hepatic arteriography and closure by portal vein embolization. A: Hepatic arteriography detected Arterio-portal shunt (APS); B: Hepatic right arteriography with microcatheter; C: Embolization of the responsible portal vein with N-butyl cyanoacrylate and iodized oil mixture; D: Repeated hepatic right artery angiography with a microcatheter showed that the APS had been completely blocked.
