Platypnea-Orthodeoxia Syndrome Provoked by Small Bowel Obstruction

Key Points

• The aim is to describe a rare presentation of platypnea-orthodeoxia syndrome triggered by small bowel obstruction.
• Case report detailing patient symptoms and clinical history.
• Assessment of positional changes and resulting oxygen levels.
• Evaluation of possible anatomical defects and shunting mechanisms.
• Patient exhibited dyspnea and hypoxemia upon standing after small bowel obstruction was noted.
• Primary anatomical defect was identified, contributing to increased right-to-left shunting.
• Severe hypoxemia highlighted the functional impact of positional changes.
