Bilateral adrenal vein sampling Sample Dictation

Procedure: Bilateral adrenal vein sampling

Indication:  Hypertension refractory to medication.

Date: 01/01/2022

Operators: John Doe, MD (Attending)/Jane Doe, MD (Fellow)

Medications: 3 mg IV Versed, 150 mcg IV fentanyl 

Contrast:  60 mL  non-ionic

Fluoro time:  17 minutes

Access site: Right common femoral vein with ultrasound

Complications:  None immediate.

 

Technique:

The risks, benefits, and alternatives to the procedure and sedation were explained to the patient.  The specific risks of bleeding, infection, and vascular injury were detailed and accepted. Written informed consent was obtained.  A time out/call to order was performed prior to procedure initiation.

The patient was assessed for conscious sedation and found to be an adequate candidate. A dedicated nurse monitored heart rate, blood pressure, and oxygen saturation throughout the procedure. A time out was performed prior to procedure initiation.

The right groin was prepped and draped in sterile fashion. 

The vascular structures were ultrasonographically evaluated.   Images were stored and transferred to PACS.  Under ultrasound guidance, the right common femoral vein was accessed with a micropuncture needle.  Vein patency and needle entry were documented. A 0.018″ wire was placed and the needle exchanged for a 5 French dilator.

An Amplatz wire was advanced into the inferior vena cava, and the dilator exchanged for a 5 French sheath. A 5 French pigtail catheter was advanced over the wire into the right external iliac artery and a peripheral venous blood sample was obtained. The pigtail catheter was then advanced into the IVC and venous blood samples were obtained at the suprarenal and infrarenal IVC.

Wire was then directed into the left common iliac artery and the 5 French pigtail catheter was exchanged for a Simmons 2 which was reformed over the bifurcation. Simmons 2 catheter was advanced up the IVC and the left adrenal vein was selectively catheterized. Contrast injection confirmed location.  2 separate venous blood samples were obtained from the left adrenal vein.  

Attention was then turned to the right adrenal vein.  The ostium of the right adrenal vein was selected with a C2 catheter and transcend wire was advanced distally.  3 separate adrenal vein samples were obtained. Positioning of the catheter in the right adrenal vein was confirmed by contrast injection during 3-D spin imaging.   3-D images were reformatted and reviewed on a separate workstation during the case. 

The catheter and sheath were removed, and hemostasis achieved with compression.

No immediate complication occurred, and the patient was discharged from the angiography suite in satisfactory condition.

Venous samples from the right external iliac vein, infrahepatic IVC, suprahepatic IVC, left adrenal vein, and right adrenal vein were delivered to the laboratory for quantitative analysis of aldosterone and cortisol.

Findings:

  1. The left adrenal vein is patent with normal anatomic appearance.
  2. The right adrenal vein is patent with normal anatomic appearance.
  3. The right common femoral vein is ultrasonographically patent and compresses. Needle entry was documented.  Images were stored to PACS.

Impression:

Successful adrenal vein sampling for refractory hypertension. Venous blood samples were obtained from the left and right adrenal veins, suprahepatic and intrahepatic IVC, and right external iliac vein, as described above.

Recommendation:

 

Follow-up quantitative analysis of aldosterone and cortisol.

The attending radiologist, John Doe MD   , was present for the procedure and interpreted the images.

Frequently Asked Questions

What is bilateral adrenal vein sampling?

Bilateral adrenal vein sampling is a diagnostic procedure used to measure hormone levels, specifically aldosterone and cortisol, from both adrenal glands. It is typically performed to evaluate patients with hypertension that does not respond well to medication. The procedure helps determine if one or both adrenal glands are overproducing hormones, which can guide treatment decisions.

How is adrenal vein sampling performed?

During adrenal vein sampling, a catheter is inserted into a large vein, usually the femoral vein in the groin area, using ultrasound guidance. The catheter is then navigated to each adrenal vein to collect blood samples. Contrast dye is often used to ensure correct placement, and the procedure is monitored via fluoroscopy. Blood samples from the adrenal veins are analyzed for hormone levels.

What are the risks of adrenal vein sampling?

Adrenal vein sampling is generally safe, but like any invasive procedure, it carries some risks. Potential complications include bleeding, infection, and vascular injury. The risks are explained to the patient before the procedure, and informed consent is obtained. Immediate complications are rare, especially when performed by experienced medical professionals.

Why might a doctor recommend adrenal vein sampling?

A doctor may recommend adrenal vein sampling for patients with hypertension that does not respond to conventional medications. This condition can be caused by overproduction of hormones such as aldosterone from one or both adrenal glands. The procedure helps determine which gland is affected, allowing for targeted treatment, such as surgery or medication adjustments.

What should patients expect after adrenal vein sampling?

After the procedure, patients are monitored for any immediate complications. They can usually return home the same day. It's normal to experience mild discomfort or bruising at the catheter insertion site. Results from the blood samples typically guide further treatment, such as medication changes or surgical intervention, based on hormone levels.

How long does adrenal vein sampling take?

The adrenal vein sampling procedure typically takes about one to two hours. This includes preparation, the procedure itself, and post-procedure monitoring. The exact duration can vary depending on the complexity of the individual's anatomy and any technical challenges encountered during the sampling.

What is the role of contrast dye in adrenal vein sampling?

Contrast dye is used in adrenal vein sampling to ensure the catheter is correctly positioned in the adrenal veins. The dye enhances imaging visibility under fluoroscopy, allowing the medical team to confirm the catheter's location and successfully obtain accurate blood samples from the correct veins.

What is the significance of aldosterone and cortisol in adrenal vein sampling?

Aldosterone and cortisol are hormones produced by the adrenal glands. Aldosterone helps regulate blood pressure by controlling sodium and potassium levels, while cortisol plays a role in stress response and metabolism. Measuring these hormones in blood samples from the adrenal veins helps identify overproduction issues, aiding in the diagnosis and treatment of hypertension.
