This article presents the case of a middle-aged man who came to the emergency room referring to the symptoms described, with a history of central venous access established approximately 4 years ago. The patient was diagnosed with superior vena cava syndrome and treated with anticoagulants and removal of the catheter. After a week of admission with anticoagulation, the patient clinically improved with a considerable decrease in thrombus and pharyngolaryngeal and subcutaneous mucosal oedema. In the differential diagnosis of dysphagia and dyspnoea, we must also consider systemic diseases, and more specifically, these symptoms such as those described, and think about this entity because of its severity.<\/jats:p>","DOI":"10.1136\/bcr-2023-257231","type":"journal-article","created":{"date-parts":[[2024,9,12]],"date-time":"2024-09-12T14:55:10Z","timestamp":1726152910000},"page":"e257231","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":0,"title":["Dysphagia as a manifestation in superior vena cava syndrome"],"prefix":"10.1136","volume":"17","author":[{"given":"Noelia","family":"Ortega Beltr\u00e1","sequence":"first","affiliation":[{"name":"Otorhinolaringology, Hospital General de Elda, Elda, Valenciana, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sara Mar\u00eda","family":"Ferrero Coloma","sequence":"additional","affiliation":[{"name":"Otorhinolaringology, Hospital General de Elda, Elda, Valenciana, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Manuel","family":"Mat\u00edas S\u00e1nchez","sequence":"additional","affiliation":[{"name":"Otorhinolaringology, Hospital General de Elda, Elda, Valenciana, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6574-1550","authenticated-orcid":false,"given":"Francisco","family":"Pons Rocher","sequence":"additional","affiliation":[{"name":"Cirurgia (Otorhinolaringology), Universitat de Valencia Facultat de Medicina i Odontologia, Valencia, Spain"},{"name":"Otorrinolaringologia, Hospital Universitario Doctor Peset, Valencia, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2024,9,12]]},"reference":[{"key":"2025082722261984000_17.9.e257231.1","doi-asserted-by":"crossref","first-page":"152","DOI":"10.5005\/jp-journals-10071-23140","article-title":"Hyperacute Superior Vena Cava Syndrome associated with Central Venous Catheter Insertion","volume":"23","author":"Edginton","year":"2019","journal-title":"Indian J Crit Care Med"},{"key":"2025082722261984000_17.9.e257231.2","doi-asserted-by":"publisher","DOI":"10.1503\/cmaj.220669"},{"key":"2025082722261984000_17.9.e257231.3","doi-asserted-by":"crossref","first-page":"132","DOI":"10.1159\/000525795","article-title":"Vena Cava Superior Syndrome Six Years after Central Venous Catheter Removal in a Patient on Hemodialysis","volume":"12","author":"Janssen","year":"2022","journal-title":"Case Rep Nephrol Dial"},{"key":"2025082722261984000_17.9.e257231.4","doi-asserted-by":"crossref","first-page":"15","DOI":"10.3941\/jrcr.v12i4.3339","article-title":"Thrombogenic superior vena cava syndrome from long-standing central venous access in a 5-year-old patient treated with balloon-expandable stents","volume":"12","author":"Ji","year":"2018","journal-title":"J Radiol Case Rep"},{"key":"2025082722261984000_17.9.e257231.5","unstructured":"Armijos RJT , Sell\u00e1n TVS , Lara AMC , et al .
