Abstract
OBJECTIVE: Vena cava superior syndrome comprises various symptoms of compression of vena cava superior. The results of increased venous pressure in the upper body may cause edema of the head and neck associated with cyanosis, plethora and distended subcutaneous vessels. Vena cava superior syndrome is rare in childhood. Therefore, we planned this retrospective study. METHODS: The retrospective study was carried out on the children with mediastinal tumors in the Department of Pediatric Hematology-oncology, Erciyes University Faculty of Medicine, Kayseri, Turkey , from January 2010 to December 2017. Diagnostic procedures included hematological investigations, chestradiography, thoracic computed tomography, echocardiography and lymph node or mediastinal biopsy. RESULTS: In this study, 19 (five were female) of 41 patients with mediastinal tumors had Vena cava superior syndrome. Diagnosis included Hodgkin's lymphoma in seven (37%), non-Hodgkin's lymphoma in six (32%), acute T- lymphoblastic leukemia in four (21%), neuroblastoma and anaplastic round cell sarcoma in one each respectively. All of the 19 patients' facial swelling, venous distention and mediastinal widening. All patients received intravenous corticosteroids (0.6 mg/kg dexamethasone). Furthermore, the patient with anaplastic round cell sarcoma received emergency radiotherapy. No patients died because of Vena cava superior syndrome. CONCLUSION: Vena cava superior syndrome is a medical emergency that requiresurgent treatment. Vena cava superior syndrome studies in children are rare. In this retrospective study, we found that the most common cause of Vena cava superior syndrome was Hodgkin's lymphoma different from literature.
