The association between obstructive sleep apnea and SVCS has not been extensively evaluated. To our knowledge, only 5 cases of obstructive sleep apnea in SVCS have been reported in the literature. We presented a 53-year-old man who was admitted with dyspnea, edema of the face, and excessive daytime sleepiness. Chest radiography and computed tomography revealed lung cancer. A biopsy of the tumor revealed squamous cell carcinoma. Obstructive sleep apnea was diagnosed by polysomnography (apnea hypopnea index: 13 per hour). After radiation and chemotherapy, edema of the face, snoring, and daytime sleepiness were alleviated, and the patient's apnea hypopnea index decreased to 0.6 per hour. In conclusion, there is a relationship between obstructive sleep apnea and SVCS.eninfo:eu-repo/semantics/closedAccessObstructive sleep apneaSuperior vena cava syndromePolysomnographySquamous cell cancerVena-cava syndromeArticle0002498673000072-s2.0-353489486065025038817922976OncologyNeurofibromatosis 1; Pulmonary Hypertension; Plexiform NeurofibromaAdultAnalytic methodArticleCancer chemotherapyCancer radiotherapyCase reportComputer assisted tomographyDaytime somnolenceDyspneaFace edemaHistopathologyHumanHuman cellLung cancerMalePhysical examinationPolysomnographyRem sleep deprivationSleep apnea syndromeSnoringSquamous cell carcinomaSuperior cava vein syndromeThorax radiographyTumor biopsy
