Transcatheter CT arteriography‐guided irreversible electroporation of locally advanced pancreatic adenocarcinoma: A pictorial essay

Summary Visibility of the tumour and its surroundings during the ablative procedure is crucial for optimal treatment planning, needle placement, ablation zone coverage and postprocedural control. The use of transcatheter CT arteriography providing real‐time image guidance has proven to be of additional value for thermal liver ablation. The general advantages of the technique could be of value for other indications and ablation techniques as well, especially when requiring multiple needle placements in the vicinity of precarious vascular structures. This pictorial essay presents six clinical cases that illustrate transcatheter CT arteriography guidance during the treatment of locally advanced pancreatic cancer with irreversible electroporation. The illustrations highlight the technique's ability to improve visibility of vascular structures and the advantage of real‐time monitoring and treatment of intraprocedural vascular complications. The use of transcatheter CT arteriography can support the interventionalist with respect to periprocedural safety and accuracy of electrode placement for pancreatic irreversible electroporation.
