Diagnosis
The diagnosis of Boerhaave's syndrome is made after:
- chest X-ray:
- after a few hours, air and fluid in the pleural cavity
- mediastinal emphysema
- in up to 20% of cases, the 'Nacleario V-sign' may be seen as radiolucent streaks that dissect the retrocardiac fascia to form the letter V. This is a specific but insensitive radiographic sign of oesophageal perforation.
- contrast studies: definitive diagnosis made with gastrograffin swallow to show the site of the perforation
- CT scanning. CT findings may include periesophageal and mediastinal gas, mediastinal fluid collections, oesophageal wall thickening, pleural effusion, pneumothorax, and hydrothorax. (1)
