POSITIONING A RIGHT ATRIAL AIR ASPIRATION CATHETER USING TRANSESOPHAGEAL ECHOCARDIOGRAPHY

The occurrence of venous air embolism (VAE) during neurosurgery in the sitting position is well documented. The optimal position of an air a spiration catheter appears to be with the catheter tip at the junction of the right atrium and superior vena cava (SVC). A number of localiz ation techniques have been described, with the electrocardiographic gu ided technique being the most commonly employed. This case report desc ribes the use of transesophageal echocardiography (TEE) for the precis e and timely placement of a right atrial-SVC air aspiration catheter.
