Here, we report a 29\u2010year\u2010old man with acute type A AoD who developed right pneumothorax before undergoing emergency aortic repair via median sternotomy. Postoperatively, the pneumothorax recurred and rapidly progressed to extensive cervical, thoracic, and abdominal subcutaneous emphysema (SE). Recurrent pneumothorax persisted despite chest drainage. Subsequent evaluation revealed right apical pulmonary bullae; however, the overall clinical course suggested a multifactorial etiology, including persistent coughing, positive\u2010pressure ventilation, internal jugular venous catheterization, wound air leakage, and drainage\u2010related factors. Mediastinal pleural disruption, along with a low body mass index (BMI) and limited soft\u2010tissue buffering, may have further facilitated air dissection along tissue planes and increased the severity of SE. After 2\u2009weeks of chest tube drainage, the SE gradually resolved, and no further pneumothorax was observed after tube removal. This case emphasizes the importance of prompt recognition, repeated imaging assessment, and individualized drainage management in patients with perioperative pneumothorax and extensive SE undergoing cardiac surgery.<\/jats:p>","DOI":"10.1002\/ccr3.72468","type":"journal-article","created":{"date-parts":[[2026,4,8]],"date-time":"2026-04-08T03:35:20Z","timestamp":1775619320000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Recurrent Pneumothorax With Extensive Subcutaneous Emphysema During the Perioperative Course of Type A Aortic Dissection: A Case Report"],"prefix":"10.1002","volume":"14","author":[{"given":"Qiulin","family":"Ran","sequence":"first","affiliation":[{"name":"Department of Cardiovascular Surgery Beijing Anzhen Hospital, Capital Medical University, Beijing Institute of Heart Lung and Blood Vessel Diseases  Beijing China"},{"name":"The University of Hong Kong\u2010Shenzhen Hospital  Shenzhen China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zanxin","family":"Wang","sequence":"additional","affiliation":[{"name":"The University of Hong Kong\u2010Shenzhen Hospital  Shenzhen China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Minxin","family":"Wei","sequence":"additional","affiliation":[{"name":"The University of Hong Kong\u2010Shenzhen Hospital  Shenzhen China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7253-5328","authenticated-orcid":false,"given":"Bin","family":"You","sequence":"additional","affiliation":[{"name":"Department of Cardiovascular Surgery Beijing Anzhen Hospital, Capital Medical University, Beijing Institute of Heart Lung and Blood Vessel Diseases  Beijing China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,4,7]]},"reference":[{"key":"e_1_2_14_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jtcvs.2021.03.102"},{"key":"e_1_2_14_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ccl.2017.03.004"},{"key":"e_1_2_14_4_1","doi-asserted-by":"publisher","DOI":"10.1093\/bjsopen\/zrae146"},{"key":"e_1_2_14_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.athoracsur.2010.04.024"},{"key":"e_1_2_14_6_1","doi-asserted-by":"publisher","DOI":"10.7759\/cureus.31816"},{"key":"e_1_2_14_7_1","doi-asserted-by":"publisher","DOI":"10.1056\/NEJMicm2200611"},{"key":"e_1_2_14_8_1","doi-asserted-by":"publisher","DOI":"10.1055\/s\u20100029\u20101185365"},{"key":"e_1_2_14_9_1","doi-asserted-by":"publisher","DOI":"10.1177\/112972980600700103"},{"key":"e_1_2_14_10_1","doi-asserted-by":"publisher","DOI":"10.21037\/jtd\u201019\u20103752"},{"key":"e_1_2_14_11_1","doi-asserted-by":"publisher","DOI":"10.4046\/trd.2014.76.3.99"},{"key":"e_1_2_14_12_1","doi-asserted-by":"publisher","DOI":"10.1309\/AJCP79SNDHGKQFIN"},{"key":"e_1_2_14_13_1","doi-asserted-by":"publisher","DOI":"10.21037\/jtd\u201021\u2010876"},{"issue":"1","key":"e_1_2_14_14_1","first-page":"147","article-title":"Catamenial Pneumothorax","volume":"82","author":"Toffolo Pasquini M.","year":"2022","journal-title":"Medicina (Buenos Aires)"},{"key":"e_1_2_14_15_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.prro.2022.10.015"},{"key":"e_1_2_14_16_1","doi-asserted-by":"publisher","DOI":"10.3389\/fsurg.2022.956431"},{"key":"e_1_2_14_17_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00464\u2010022\u201009730\u20109"},{"key":"e_1_2_14_18_1","doi-asserted-by":"publisher","DOI":"10.1007\/s11701\u2010024\u201002112\u20104"},{"key":"e_1_2_14_19_1","doi-asserted-by":"publisher","DOI":"10.1111\/joim.12974"},{"key":"e_1_2_14_20_1","doi-asserted-by":"publisher","DOI":"10.4103\/aca.ACA_135_18"},{"key":"e_1_2_14_21_1","doi-asserted-by":"publisher","DOI":"10.1148\/radiographics.19.2.g99mr06321"},{"key":"e_1_2_14_22_1","doi-asserted-by":"publisher","DOI":"10.1046\/j.1440\u20101843.2001.00317.x"},{"key":"e_1_2_14_23_1","doi-asserted-by":"publisher","DOI":"10.12659\/AJCR.938063"},{"key":"e_1_2_14_24_1","doi-asserted-by":"publisher","DOI":"10.1097\/MD.0000000000034240"},{"issue":"10","key":"e_1_2_14_25_1","first-page":"909","article-title":"Epidural, Mediastinal and Subcutaneous Emphysema in a Patient With Suspected Torme Fruste of Marfan Syndrome","volume":"42","author":"Fujimoto K.","year":"2004","journal-title":"Nihon Koky\u016bki Gakkai Zasshi"},{"key":"e_1_2_14_26_1","doi-asserted-by":"publisher","DOI":"10.1093\/icvts\/ivt532"},{"key":"e_1_2_14_27_1","doi-asserted-by":"publisher","DOI":"10.1001\/archinte.1984.00350190143024"},{"key":"e_1_2_14_28_1","first-page":"117","article-title":"Subcutaneous Emphysema","volume":"11","author":"Samlaska C.
