pneumopericardium

Pronunciation: new-mo-pair-ih-KAR-dee-um

Rare complication of laparoscopic surgery involving accumulation of CO₂ gas within the pericardial space.

Full Definition

An uncommon but serious complication of laparoscopic procedures characterized by the presence of carbon dioxide gas within the pericardial sac. This condition can occur when insufflated CO₂ migrates through anatomical communications such as pleuropericardial connections or patent foramen ovale, or through direct diaphragmatic defects. Pneumopericardium may cause cardiac tamponade-like symptoms and requires immediate recognition and treatment, often involving pericardiocentesis or conversion to open surgery.

Usage

Usage note: Document as serious complication requiring immediate intervention and monitoring.
