Renal arteriography is a minimally invasive diagnostic imaging procedure used to visualize the arteries supplying the kidneys. It is essential for identifying vascular problems that may affect kidney function, such as stenosis, malformations, or other lesions. At Topmed Medical Center in Târgu Mureș, this investigation is performed with precision using state-of-the-art technology for clear and safe results.
The procedure involves using a catheter inserted through a blood vessel, usually in the arm or groin, which is guided to the renal arteries. An iodine-based contrast agent is injected through the catheter, and detailed images of the blood vessels are obtained using X-rays.
When is renal arteriography recommended?
This procedure is indicated when the doctor suspects vascular problems affecting the kidneys or their function:
- Secondary hypertension:
- Caused by renal artery stenosis (narrowing of the renal arteries).
- Assessment of renal lesions:
- In cases of trauma, tumors, or other conditions that may affect kidney blood supply.
- Monitoring aneurysms:
- Identifying and monitoring abnormal dilations of the renal arteries.
- Surgical planning:
- Before procedures such as vascular reconstruction surgery or kidney transplantation.
- Diagnosis of renal artery disease:
- Assessment of blood flow and artery condition in the context of kidney diseases.
How is the procedure performed?
- Patient preparation:
- A local anesthetic is administered at the site where the catheter will be inserted.
- Catheter insertion:
- The catheter is inserted through a peripheral artery (arm or groin) and guided to the renal arteries.
- Contrast agent injection:
- The contrast helps highlight the renal arteries in detail on the X-ray images.
- Image analysis:
- The specialist analyzes the images to identify stenosis, blockages, or other vascular abnormalities.
What are the advantages of renal arteriography?
- Accurate diagnosis:
- Provides detailed information about blood flow in the renal arteries.
- Treatment planning:
- The results help the interventional doctor decide on the best treatment options, including angioplasty or surgery.
- Minimally invasive:
- Compared to other methods, it requires only a small incision and allows for quick recovery.
- Monitoring conditions:
- Allows evaluation of the progression of vascular conditions or the effectiveness of treatment.
Risks and contraindications of the procedure
Although considered a safe procedure, renal arteriography may involve some risks:
- Vascular: bruising/bleeding at the catheter insertion site.
- Allergic reactions: to the iodine-based contrast agent.
- Contrast-induced nephropathy: risk for patients with pre-existing kidney conditions.
- Radiation exposure: requires proper monitoring, although the dose is controlled.
Relative contraindications:
- History of allergic reaction to contrast agent, without prior glucocorticoid preparation.
- Acute renal failure.
- Severe anemia (hemoglobin below 8 mg/dl).
- Decompensated heart failure.
- Uncooperative patient.
- Severe active infections.
Preparation for renal arteriography
- Pre-procedure consultation:
- The doctor will assess medical history, current treatments, and any allergies.
- Dietary restrictions:
- Avoid eating or drinking for 4 hours before the procedure.
- Medication:
- Inform your doctor about any medications you are taking, especially anticoagulants and nephrotoxic drugs.
Recovery after renal arteriography
- Post-procedure monitoring:
- The patient is monitored for several hours to prevent complications.
- Resuming activities:
- Normal activities can be resumed after 24 hours, avoiding intense physical effort.
- Caring for the insertion site:
- Follow your doctor's instructions to protect the puncture area.
