The purpose of this study was to evaluate the dynamic position of the chest port and catheter tip, comparing a demographically matched cohort of female breast cancer patients with right\u2010 or left\u2010sided chest ports.<\/jats:p><jats:p><jats:bold>Methods:<\/jats:bold> 142 female patients with breast cancer requiring chest port insertion for chemotherapy and imaging confirming catheter tip position initially with supine fluoroscopy and follow\u2010up with erect chest radiography over a 5\u2010year period were identified. Data points analyzed were catheter tip\u2010to\u2010carina distance and the distance from the port to the ipsilateral infraclavicular border. Intraprocedural measurements were taken in the supine position during chest port insertion and compared with follow\u2010up erect chest radiography. The catheter tip position was also allocated a zone within the venous system on both image sets to assess for significant retraction to a more proximal zone in the erect position. Imaging within 12\u2010months of chest port insertion was also screened to identify port\u2010related complications.<\/jats:p><jats:p><jats:bold>Results:<\/jats:bold> The whole cohort showed significant retraction of the catheter tip (cephalad) (<jats:italic>p<\/jats:italic> &lt; 0.001) and protraction of the port (caudal) (<jats:italic>p<\/jats:italic> &lt; 0.001). The median tip\u2010to\u2010carina distance decreased from 38.3\u2009mm to 28.6\u2009mm and the port\u2010to\u2010clavicle distance increased from 31.3\u2009mm to 64.6\u2009mm. Right\u2010sided chest ports had increased tip\u2010to\u2010catheter retraction (15\u2009mm) compared with left\u2010sided (6.9\u2009mm) (<jats:italic>p<\/jats:italic> = 0.310). A complication was identified in 8.5% of the right\u2010sided and 11% of the left\u2010sided ports. Zone migration was significantly associated with the occurrence of a complication in left\u2010sided ports (<jats:italic>p<\/jats:italic> = 0.023).<\/jats:p><jats:p><jats:bold>Conclusion:<\/jats:bold> When assessing chest port catheter tip position between supine and erect radiographic studies in female patients with breast cancer, retraction cephalad will occur and this is more apparent in right\u2010sided ports. Change in catheter tip position was not associated with a significant increase in complication rate unless it occurred in left\u2010sided ports where zone migration was evident.<\/jats:p>","DOI":"10.1155\/tbj\/7358397","type":"journal-article","created":{"date-parts":[[2024,12,21]],"date-time":"2024-12-21T07:18:36Z","timestamp":1734765516000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Catheter Tip Migration in Female Patients With Breast Cancer: A Retrospective Comparative Study of Right\u2010 and Left\u2010Sided Chest Ports"],"prefix":"10.1155","volume":"2024","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9110-2579","authenticated-orcid":false,"given":"Alexander T.","family":"O\u2019Mahony","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Aidan","family":"Coffey","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0002-8868-1375","authenticated-orcid":false,"given":"Patrick W.","family":"O\u2019Regan","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Emily","family":"Walsh","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Brian","family":"Carey","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"James","family":"Ryan","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Niamh","family":"Dorney","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0276-1335","authenticated-orcid":false,"given":"Owen J.","family":"O\u2019Connor","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jack","family":"Gleeson","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Stephen P.","family":"Power","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2024,12,20]]},"reference":[{"key":"e_1_2_10_1_2","doi-asserted-by":"publisher","DOI":"10.5754\/hge09283"},{"key":"e_1_2_10_2_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.ejso.2016.10.020"},{"key":"e_1_2_10_3_2","doi-asserted-by":"publisher","DOI":"10.1186\/s13244-019-0770-2"},{"key":"e_1_2_10_4_2","doi-asserted-by":"publisher","DOI":"10.1097\/01.rvi.0000127890.47187.91"},{"key":"e_1_2_10_5_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00520-004-0723-1"},{"key":"e_1_2_10_6_2","doi-asserted-by":"publisher","DOI":"10.1016\/s1051-0443(97)70585-2"},{"key":"e_1_2_10_7_2","article-title":"Vessel Health and Preservation: The Right Approach for Vascular Access","author":"Moureau N.
