Cerebral Air Embolism after Central Venous Catheter Self-Extraction

Cerebral air embolism associated with central venous catheter insertion and removal is a rare but serious complication. There are many hypotheses on how air bubbles might be transported from the venous system to intracranial vessels. The literature has described how intra-cardiac defects transpulmonary passage and even retrograde flow of gas bubbles can explain this phenomenon. We present a case that illustrates the devastating effects of cerebral air embolism after a patient selfextracted his central venous catheter.
