To determine the patency of a LeVeen shunt, the radiopharmaceutical is administered into:

• A. A vein
• B. The peritoneal cavity
• C. The intrathecal space
• D. The shunt tubing

Answer: (B)

The correct answer is the peritoneal cavity. A LeVeen shunt is a medical device used to relieve ascites in patients by draining excess fluid from the peritoneal cavity. To evaluate the functionality or patency of the LeVeen shunt, a radiopharmaceutical is administered directly into the peritoneal cavity. This method allows for tracking the movement of the radiopharmaceutical through the shunt to the vascular system or to the designated drainage area. When the radiopharmaceutical is injected into the peritoneal cavity, it can be visualized using imaging techniques to see if it flows through the shunt properly, indicating that it is patent and functioning as intended. The other options do not accurately reflect the anatomical structures or methods relevant to assessing the LeVeen shunt's patency. Administering the radiopharmaceutical into a vein or the intrathecal space would not provide the necessary information regarding the function of the LeVeen shunt, and injecting it directly into the shunt tubing is not a recognized method for checking its patency.
