Patients with primary and secondary malignant liver lesions located in the hepatic dome who underwent percutaneous computed tomography-guided microwave ablation using a computer-assisted navigation system under local anesthesia were prospectively evaluated. The primary objective was technical success. Materials and Methods: The sample consisted of 10 participants (16 lesions) with a mean age of 60.60 years (SD = 9.25 years) and a mean size of 20.37 \u00b1 7.29 cm, and the mean follow-up time was 3.4 months (SD = 1.41) months. Results: Primary technical success was 93.75%. Tumor remnant was noticed at one month follow-up in a single metastatic lesion, which was re-treated with an ablation session, and no tumor remnant was depicted in the subsequent imaging follow-up (secondary technical success 100%). Grade I self-limited complications (according to the CIRSE classification system) included small pleural effusion (n = 1) and minor bleeding post antenna removal (n = 1) requiring nothing but observation. Conclusions: the findings of the present study indicate that percutaneous navigation under local anesthesia is a safe and efficacious approach for computed tomography-guided microwave ablation of malignant liver lesions located in the hepatic dome. Large randomized controlled studies are warranted to observe treatment effectiveness and compare the results with those of other options.<\/jats:p>","DOI":"10.3390\/medicina57101056","type":"journal-article","created":{"date-parts":[[2021,10,11]],"date-time":"2021-10-11T01:57:54Z","timestamp":1633917474000},"page":"1056","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Percutaneous Navigation under Local Anesthesia for Computed Tomography-Guided Microwave Ablation of Malignant Liver Lesions Located in the Hepatic Dome"],"prefix":"10.3390","volume":"57","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1424-7464","authenticated-orcid":false,"given":"Dimitrios K.","family":"Filippiadis","sequence":"first","affiliation":[{"name":"2nd Department of Radiology, University General Hospital \u201cATTIKON\u201d, Medical School, National and Kapodistrian University of Athens, 1 Rimini Str., 12462 Athens, Greece"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0050-284X","authenticated-orcid":false,"given":"Georgios","family":"Velonakis","sequence":"additional","affiliation":[{"name":"2nd Department of Radiology, University General Hospital \u201cATTIKON\u201d, Medical School, National and Kapodistrian University of Athens, 1 Rimini Str., 12462 Athens, Greece"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2705-5696","authenticated-orcid":false,"given":"Argyro","family":"Mazioti","sequence":"additional","affiliation":[{"name":"2nd Department of Radiology, University General Hospital \u201cATTIKON\u201d, Medical School, National and Kapodistrian University of Athens, 1 Rimini Str., 12462 Athens, Greece"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Athanasios","family":"Tsochatzis","sequence":"additional","affiliation":[{"name":"2nd Department of Radiology, University General Hospital \u201cATTIKON\u201d, Medical School, National and Kapodistrian University of Athens, 1 Rimini Str., 12462 Athens, Greece"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Thomas","family":"Vrachliotis","sequence":"additional","affiliation":[{"name":"2nd Department of Radiology, University General Hospital \u201cATTIKON\u201d, Medical School, National and Kapodistrian University of Athens, 1 Rimini Str., 12462 Athens, Greece"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5429-6041","authenticated-orcid":false,"given":"Alexis","family":"Kelekis","sequence":"additional","affiliation":[{"name":"2nd Department of Radiology, University General Hospital \u201cATTIKON\u201d, Medical School, National and Kapodistrian University of Athens, 1 Rimini Str., 12462 Athens, Greece"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nikolaos","family":"Kelekis","sequence":"additional","affiliation":[{"name":"2nd Department of Radiology, University General Hospital \u201cATTIKON\u201d, Medical School, National and Kapodistrian University of Athens, 1 Rimini Str., 12462 Athens, Greece"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2021,10,3]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1386","DOI":"10.1093\/annonc\/mdw235","article-title":"ESMO consensus guidelines for the management of patients with metastatic colorectal cancer","volume":"27","author":"Cervantes","year":"2016","journal-title":"Ann.
