Figure 3, A and B. These figures are fluoroscopic images acquired as Ethiodol contrast medium extravasates from the region of the thoracic
lymph duct over the twelfth thoracic vertebra. A) The patient was quietly breathing during this study. Bile duct tubing with a wire shows the dilation
of the vessel and the extravasation of Ethiodol from the thoracic duct at the second lumbar vertebra. B) A fluoroscopic image captured during the
Valsalva maneuver, which increased the patient’s abdominal pressure and caused the Ethiodol in Figure B to exit via the thoracic lymph duct.
BT, Bile duct tubing; W, wire; TD, thoracic duct; T12, twelfth thoracic vertebra; L2, second lumbar vertebra; A, aorta.
