A Case of Pancreatic Neuroendocrine Tumor with Liver Metastases Demonstrating the Possibility of Enhanced ACTH Production by the SACI Test

Figure 4

Schema for the SACI test and angiography. (a) Schema for the selective arterial calcium injection (SACI) test. Stars indicate the arteries tested in the current patient. (b) A catheter was inserted from the femoral vein into the middle hepatic vein and a catheter was inserted percutaneously and placed transhepatically into the main trunk of the portal vein, and the ACTH concentrations were measured. (c) SMA angiography. The replaced common hepatic artery (CHA) and dorsal pancreatic artery (DPA) are depicted. (d) Selective angiography from DPA showed that the pancreatic tumor was stained in a basket shape.
