HepACAGA was performed in an angiography-suite under general anesthesia. The hepatic artery was catheterized for selective contrast injection. C-arm CT and guidance software were then used to visualize the tumor and the microwave antenna was inserted during apnea. Pre- and post-ablation C-arm CTs were performed and ablation margins assessed. Technical success, antenna placement deviation, number of repositions, tumor recurrence, and safety were evaluated. Technical success was defined as a tumor that was ablated according to the HepACAGA technique.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Results<\/jats:title>\n                <jats:p>A total of 21 patients (28 tumors) were included. The main tumor type was colorectal cancer liver metastases (11\/21, 52%), followed by hepatocellular carcinoma (7\/21, 33%), neuroendocrine tumor metastases (1\/21, 5%), and other tumor types (2\/21, 10%). The technical success rate was 93% (26\/28 tumors) with two small hypovascular lesions unable to be identified. A single microwave antenna was used in all patients. The median antenna placement deviation was 1\u00a0mm (range 0\u20136\u00a0mm). At a median follow-up time of 16\u00a0months (range 5\u201322\u00a0months), there was no tumor recurrence in any patient. Safety analysis showed a complication rate of 5% grade 2 and 5% grade 3.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Conclusion<\/jats:title>\n                <jats:p>HepACAGA was demonstrated to be a safe and effective percutaneous ablation technique, without any local tumor recurrence in this study.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Graphic Abstract<\/jats:title>\n                \n              <\/jats:sec>","DOI":"10.1007\/s00270-023-03545-4","type":"journal-article","created":{"date-parts":[[2023,9,13]],"date-time":"2023-09-13T16:02:34Z","timestamp":1694620954000},"page":"1365-1374","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":30,"title":["Hepatic Arteriography and C-Arm CT-Guided Ablation (HepACAGA) to Improve Tumor Visualization, Navigation and Margin Confirmation in Percutaneous Liver Tumor Ablation"],"prefix":"10.1007","volume":"46","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4735-655X","authenticated-orcid":false,"given":"Maarten L.
