CAMRT Radiography Practice Exam

Which position should a patient be in to check for esophageal varices during fluoroscopy?

1. Sitting upright

2. Recumbent, slightly trendelenberg

3. Prone

4. Supine

The correct answer is: Recumbent, slightly trendelenberg

To assess esophageal varices during fluoroscopy, placing the patient in a recumbent position with a slight Trendelenburg tilt is most effective. This positioning helps by promoting better contrast filling of the esophagus while minimizing the potential for respiratory compromise and allowing the varices to be more clearly visualized with the fluoroscopic equipment. When the patient is slightly tilted, the effects of gravity assist in enhancing the visibility of the varices, as they can shift slightly due to vascular pressure changes. This angle can also help in differentiating varices from other structures, aiding in accurate diagnosis. Furthermore, this position is more comfortable for the patient during the procedure, as it can reduce the tension on the esophagus. Incorporating this position into the examination protocol allows radiologists to obtain more definitive images, ensuring precise evaluation of the varices, guiding potential treatment options or further investigations if necessary.
