Air embolism

Longitudinal ultrasound of the kidney (image 1) in a patient with congenital heart disease and umbilical arterial catheter shows a linear hyperechoic region (arrow) within the cortex. The echogenic focus represents air embolism introduced from the umbilical arterial catheter. Air embolism can occur in any patient with a vascular catheter when air is introduced during line placement, medication administration, or as a result of penetrating trauma patients are typically asymptomatic. However, depending on the location of the air, fetal complications may occur.
