Figure 1. a–c.

Images obtained from a 37-year-old male with a splenic artery pseudoaneurysm caused by acute pancreatitis who underwent endovascular treatment using vessel-detection software. The splenic artery angiogram (a) shows the target pseudoaneurysm (arrow), but the exact origin, location, and vasculature of the damaged artery are not clear. The software analysis of the volume-rendered C-arm CT image of the splenic artery (b) indicates a single bleeding site (arrowhead) at the second branch of the splenic artery. The software indicates the arterial path from the catheter to the target aneurysm in green. Note the arterial shortcut created at the hairpin turn in a single artery (arrow). The maximum intensity projection C-arm CT image (c) obtained after coil embolization of the parent artery (arrow) confirms disappearance of the pseudoaneurysm.
