Methods: This was a retrospective study nested into a larger prospective cohort study including patients with RMPE recruited from a tertiary university teaching hospital between June of 2009 and September of 2014. The patients underwent pleural catheter insertion followed by bedside pleurodesis. Chest CT scans were performed twice: immediately before pleurodesis (iCT) and 30 days after pleurodesis (CT30). Catheter positioning was categorized based on iCT scans as posterolateral, anterior, fissural, and subpulmonary. We used the pleural volume on iCT scans to estimate early lung expansion and the difference between the pleural volumes on CT30 and iCT scans to evaluate radiological success of pleurodesis. Clinical pleurodesis success was defined as no need for any other pleural procedure. Results: Of the 131 eligible patients from the original study, 85 were included in this nested study (64 women; mean age: 60.74 years). Catheter tip positioning was subpulmonary in 35 patients (41%), anterior in 23 (27%), posterolateral in 17 (20%), and fissural in 10 (12%). No significant differences were found among the groups regarding early lung expansion (median residual pleural cavity = 377 mL; interquartile range: 171-722 mL; p = 0.645), radiological success of pleurodesis (median volume = 33 mL; interquartile range: \u2212225 to 257 mL; p = 0.923), and clinical success of pleurodesis (85.8%; p = 0.676). Conclusions: Our results suggest that the position of the tip of the pleural catheter influences neither early lung expansion nor bedside pleurodesis success in patients with RMPE.<\/jats:p>","DOI":"10.1590\/s1806-37562016000000240","type":"journal-article","created":{"date-parts":[[2017,7,19]],"date-time":"2017-07-19T18:14:31Z","timestamp":1500488071000},"page":"190-194","source":"Crossref","is-referenced-by-count":0,"title":["Ultrasound-guided intrapleural positioning of pleural catheters: influence on immediate lung expansion and pleurodesis in patients with recurrent malignant pleural effusion"],"prefix":"10.1590","volume":"43","author":[{"given":"Pedro Henrique Xavier Nabuco de","family":"Araujo","sequence":"first","affiliation":[{"name":"Universidade de S\u00e3o Paulo, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ricardo Mingarini","family":"Terra","sequence":"additional","affiliation":[{"name":"Universidade de S\u00e3o Paulo, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Thiago da Silva","family":"Santos","sequence":"additional","affiliation":[{"name":"Universidade de S\u00e3o Paulo, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rodrigo Caruso","family":"Chate","sequence":"additional","affiliation":[{"name":"Universidade de S\u00e3o Paulo, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Antonio Fernando Lins de","family":"Paiva","sequence":"additional","affiliation":[{"name":"Universidade de S\u00e3o Paulo, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Paulo Manuel","family":"P\u00eago-Fernandes","sequence":"additional","affiliation":[{"name":"Universidade de S\u00e3o Paulo, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"530","reference":[{"issue":"2","key":"ref1","doi-asserted-by":"crossref","first-page":"244","DOI":"10.1111\/j.1440-1843.2010.01913.x","article-title":"Pleural controversy Optimal chest tube size for drainage","volume":"16","author":"Light RW","year":"2011","journal-title":"Respirology"},{"issue":"4","key":"ref2","doi-asserted-by":"crossref","first-page":"420","DOI":"10.1097\/COC.0b013e3181aacbbf","article-title":"Diagnosis and treatment of malignant pleural effusion a systematic literature review and new approaches","volume":"33","author":"Lombardi G","year":"2010","journal-title":"Am J Clin Oncol"},{"issue":"3","key":"ref3","doi-asserted-by":"crossref","first-page":"215","DOI":"10.1111\/j.1365-2702.1997.tb00307.x","article-title":"Underwater seal chest drains the patient's experience","volume":"6","author":"Owen S","year":"1997","journal-title":"J Clin Nurs"},{"key":"ref4","doi-asserted-by":"crossref","first-page":"ii61","DOI":"10.1136\/thx.2010.137026","article-title":"Pleural procedures and thoracic ultrasound British Thoracic Society Pleural Disease Guideline 2010","volume":"65","author":"Havelock T","year":"2010","journal-title":"Thorax"},{"issue":"1","key":"ref5","doi-asserted-by":"crossref","first-page":"19","DOI":"10.1378\/chest.120.1.19","article-title":"Use of small-bore vs large-bore chest tubes for treatment of malignant pleural effusions","volume":"120","author":"Parulekar W","year":"2001","journal-title":"Chest"},{"issue":"3","key":"ref6","doi-asserted-by":"crossref","first-page":"593","DOI":"10.1016\/S0954-6111(98)90315-8","article-title":"Treatment of malignant pleural effusion pleurodesis using a small percutaneous catheter.
