Key result
Subxiphoid pericardiocentesis causes pericardio-peritoneal communication, resolved conservatively with early catheter removal.
Why the study?
Peritoneal perforation during emergency subxiphoid pericardiocentesis is a rare but clinically relevant complication that requires early recognition to prevent further adverse outcomes.

This case highlights the risk of peritoneal perforation during subxiphoid pericardiocentesis and the importance of early cross-sectional imaging for atypical post-procedural symptoms.
Thevathasan et al. (2026) conducted a case report in Acute cardiac tamponade during complex PCI (n=1). Emergency subxiphoid pericardiocentesis was evaluated on Peritoneal perforation and iatrogenic pericardio-peritoneal communication. Emergency subxiphoid pericardiocentesis resulted in an iatrogenic pericardio-peritoneal communication due to peritoneal perforation, which was managed conservatively with early catheter removal.
