1. The role of digital background erasure and super-selective adrenal venous blood collection

Digital subtraction angiography and ultra-selective adrenal venous blood sampling are a valuable test for determining the cause of a pathological adrenal location, in addition to other diagnostic techniques.
One of the common causes in adrenal gland disease includes: hypertension, primary hyperaldosteronism syndrome, primary adrenal hyperplasia, adrenal myeloma.

2. Indications and contraindications for digital background erasing and super-selective adrenal venous blood collection

Indications for digitized background erasure and superselective adrenal venous blood sampling in the following cases:
Adrenal medulloblastoma Primary hyperaldosteronism Hyperselective nephropathy in:
Allergy to iodinated contrast agents Grade IV renal failure Uncontrollable coagulopathy Pregnant women

3. Steps to perform digitized scanning of background and super-selective adrenal venous blood collection

Step 1: Prepare a digital angiogram to erase the background, a dedicated electric pump, equipment related to image storage, an X-ray shield 3. Local anesthetic, pre-anesthetic and general anesthetic body if indicated, anticoagulant, anticoagulant neutralizer, water soluble iodine contrast agent. Disinfectant solution for skin, mucous membranes and medical supplies.
Step 2: Let the patient lie on his back on the scanning table, place an intravenous line and then give local anesthesia.
Step 3: Use needle 18 to poke the right common femoral vein and then insert the lead and catheter. Superselective blood collection from the right adrenal vein. It is then emptied directly into the inferior vena cava just above the right renal vein.
Step 4: Use the right adrenal superselective microcatheter, then take blood from the right adrenal vein about 5-8ml through the microcatheter and then take superselective blood from the left adrenal vein.
Step 5: Use Cobra-2 to thread into the left renal vein and then take a scan to determine the location of the left adrenal vein. Next, use a left adrenal superselective microcatheter and then collect 5-8ml of left adrenal vein blood through the microcatheter
Step 6: Take lower vena cava through a pigtail catheter and collect 5-8ml of venous blood lower motherboard.
