Adrenal Vein Sampling (AVS)
Care Before the Procedure
- Preparation:
- Follow specific instructions regarding medication adjustments and fasting.
- Discuss any allergies or medical conditions with your healthcare provider.
- Health Disclosure:
- Inform your healthcare provider about any history of bleeding disorders, medications, or prior surgeries on the adrenal glands.
Care During the Procedure
- IV sedation or local anaesthesia is typically used for patient comfort.
- The catheter is inserted and guided to the adrenal veins with imaging assistance.
- Blood samples are collected from both adrenal veins and a peripheral site.
- Patient Experience:
- Patients may experience mild discomfort during catheter insertion, but the procedure is generally well-tolerated.
- Continuous monitoring of vital signs and comfort levels is maintained throughout the procedure.
Care After the Procedure
- Patients are monitored for a short period after the procedure for any complications.
- Normal activities can usually be resumed within a day, depending on individual recovery.
- Results:
- Hormone levels from the collected samples are analysed to determine the source of aldosterone production.
- Results are interpreted by endocrinologists, who will discuss the findings and recommend further management based on the results.
- Follow-Up:
- Depending on the results, treatment options may include medications, lifestyle modifications, or surgical intervention.
- Regular follow-up appointments may be scheduled to monitor blood pressure and hormone levels.
- Note: Adrenal Vein Sampling is a valuable diagnostic tool for assessing adrenal function and managing conditions related to hormone production. Adhering to preparation instructions and maintaining communication with your healthcare provider are crucial for optimal outcomes.
