| Label | Type | Description | Intervention Names |
|---|---|---|---|
| CT-image guidance | Experimental | Previously acquired portal venous phase of CT datasets and intra-operative CT datasets were registered on a dedicated workstation. The selected volume of interest of the CT-image showing portal vein vasculature was overlaid onto the fluoroscopic display as real-time 3D CT-image guidance during the procedure. |
|
| CO2 portography | Active Comparator | two two-dimensional (2D) CO2 portograms |
|
