The risk of life-threatening cardiovascular collapse or airway compromise is well recognized in patients with large anterior mediastinal mass. The peri-operative risk predictors like site, a volume of the mass, extent on computed tomography (CT) scan of the mass are well known.We report a case of dynamic subclinical superior vena caval (SVC) obstruction evident with continuous CVP monitoring in the perioperative period and to utilize CVP changes as a risk predictor. A 30-year-old male presented to the pre-anaesthetic clinic with history of dry cough for 9 months and recent onset of weight loss.On examination, he was conscious, comfortable without clinical evidence of either tracheal or SVC obstruction. The Pemberton's sign was negative.The chest X-ray showed mediastinal widening.The CT scan revealed a large, 10.2 × 9.3 × 6.3 cm well-defined heterogeneous mixed density mass lesion lying over the brachiocephalic confluence, SVC, right atrium (RA) and right ventricular (RV) outflow tract without any pericardial or pleural effusion...
