What is Renal Artery Bypass?

Renal artery bypass is a kind of surgery that offers an alternative route (bypass) for blood to go outside a blockage in your renal arteries. A vein from your leg can be used to make the bypass, which can also be made from synthetic prosthetic materials. The vessel is secured both above and below the area that is blocked. The bypass may restore blood flow to the kidneys.

What is the purpose of a renal artery bypass?

A renal artery bypass opens the way to an occluded or narrowed renal artery, allowing blood flow to the kidneys using a bypass. This is done when:

• Uncontrolled hypertension is present.
• The kidneys' function is deteriorating step by step.
• One complication is pulmonary edema (fluid buildup in the lungs).

How do I get ready for a renal artery bypass?

Your doctor will examine you physically and also review your medical history before deciding to perform the renal artery bypass procedure. You could be asked to have specific tests done to determine how much the vessels are narrowed. Such tests may be:

• Computed Tomography Scan, CT scan, or CAT scan: This is an imaging technique that involves cross-sectional, detailed images of the body: bones, muscles, fat, and organs are revealed using X-rays and computer technology.
• Duplex Ultrasound: A non-invasive, painless test that pictures blood flow through your veins and arteries. It looks at the composition of your blood vessels and shows you whether or not your arteries are blocked.
• MRA: Magnetic resonance angiography, or MRA, is a painless test that does not involve surgery. It assesses flow through arteries using massive magnets, radio frequency technology, and a computer.

If any of these tests show narrowing of the arteries, then you may be asked to undergo an angiography, which is a blood vessel X-ray, to determine if there is a blockage.

What to expect during renal artery bypass?

Preparing for procedure

Inform your doctor of all the prescriptions you take, including over-the-counter drugs, as well as any drug allergies you may have. The day preceding your process, you will be advised not to eat or drink anything after midnight on the morning of the process.

During the procedure

Renal artery bypass is a major procedure that necessitates an incision in the abdomen and general anesthesia. In a renal artery bypass, a vein in your arm or groin is used to create a new vessel, which may be made artificially. This grafted vessel is sewn above and below the occlusion of the renal artery to offer an alternative pathway for blood to travel to the kidneys.

After the procedure

You are going to be closely monitored in the hospital following renal artery bypass. Patients are expected to stay in the hospital three to five days after surgery. After about a month, you will regain normal functioning. At home, you are supposed to continue taking your medications unless your doctor instructs otherwise. You are going to continue being monitored during follow-up visits.

What are the benefits associated with renal artery bypass?

It can help improve blood flow towards the kidneys by opening a new route by which blood can reach them. This can be helpful in the following ways:

• Controls hypertension: Renal artery bypass surgery can control renovascular hypertension.
• Preserve kidney function: The advantage of this bypass is that it preserves renal function.

Most often, bypass surgery on the renal artery is performed if angioplasty fails or if more surgical procedures are needed. In the process, a surgeon attaches a substitute blood vessel to the renal artery, sometimes hooking it to a vessel in the liver or spleen.

What are the risks associated with renal artery bypass?

Renal artery bypass hazards include:

• Kidney damage: The graft damages one or both kidneys, which may lead to a patient losing either one or both kidneys or needing to have the respective organs removed.
• Dialysis: Patients suffering from chronic kidney diseases will inherently be under dialysis post-procedure
• Blood clotting: There may be blood clotting in the arteries
• Allergic reaction: Some patients might react to the contrast used in the procedure.
• Bruising and bleeding: There can be bruising and bleeding at the insertion point.
• Misplacement of stent: Stent can be misplaced.

What is the duration of recovery?

Most patients are required to spend three to seven days in the hospital following the bypass surgery of the renal arteries. One or two weeks later, they make a doctor's visit for skin suture removal. They will take even two to four weeks to recover.
