Anemia and hypertension usually go along with renal insufficiency. If you are having antihypertensive medication it should be one of the ones that a) protect the kidney and b) prevent/reverse cardiac remodelling. The ACE inhibitors and angiotensin II antagonists have shown these effects where other antihypertensive drugs have not.

What is done if accessory renal artery causes hypertension in 14 year old?


The accessory renal artery is long and flat & if taken out that part of the kidney will die!!! Are they crazy?
----------

The renal arteries normally arise off the side of the abdominal aorta, immediately below the superior mesenteric artery, and supply the kidneys with blood. Each is directed across the crus of the diaphragm, so as to form nearly a right angle with the aorta.

The renal arteries carry a large portion of total blood flow to the kidneys. Up to a third of total cardiac output can pass through the renal arteries to be filtered by the kidneys.

The arterial supply of the kidneys is variable and there may be one or more renal arteries supplying each kidney. It is located above the renal vein.
Asymmetries before reaching kidney
Due to the position of the aorta, the inferior vena cava and the kidneys in the body, the right renal artery is normally longer than the left renal artery.

The right passes behind the inferior vena cava, the right renal vein, the head of the pancreas, and the descending part of the duodenum.
The left is somewhat higher than the right; it lies behind the left renal vein, the body of the pancreas and the lienal vein, and is crossed by the inferior mesenteric vein.

At kidney
Before reaching the hilus of the kidney, each artery divides into four or five branches; the greater number of these lie between the renal vein and ureter, the vein being in front, the ureter behind, but one or more branches are usually situated behind the ureter.

Each vessel gives off some small inferior suprarenal branches to the suprarenal gland, the ureter, and the surrounding cellular tissue and muscles.

One or two accessory renal arteries are frequently found, more especially on the left side they usually arise from the aorta, and may come off above or below the main artery, the former being the more common position. Instead of entering the kidney at the hilus, they usually pierce the upper or lower part of the gland.


Diseases of the renal arteries
Renal artery stenosis, or narrowing of one or both renal arteries will lead to hypertension as the affected kidneys release renin to increase blood pressure to preserve perfusion to the kidneys. RAS is diagnosed with an MRA (magnet-resonance scan) of abdomen. It is treated with the use of balloon angioplasty and stents, if necessary.

Atherosclerosis can also affect the renal arteries and can lead to poor perfusion of the kidneys leading to reduced kidney function and, possibly, renal failure.  (+ info)

What is the renal function status of a 54 year old male whose creatinine level is 1.3, has only hypertension.?


Normal levels of creatinine in the blood are approximately 0.6 to 1.2 milligrams (mg) per deciliter (dl) in adult males.

Levels that reach 10.0 or more in adults may indicate the need for a dialysis machine to remove wastes from the blood.

You're pretty much in the norm, but consult your doctor if you have any concerns...he or she can certainly answer your questions better than anyone(including me) here.  (+ info)

why is it hypertension is one of the factor than can cause chronic renal failure?


The increased blood pressure puts extra pressure on the glomeruli [the ball shaped filtering packets of the inner kidney] and eventually this causes damage.

Sadly, the body responds to failing kidneys by increasing the blood pressure in an effort to make said kidneys more efficient, so this is a vicious circle.

While increased blood pressure does have some effect on the small blood vessels of major organs, that is more an effect of the glycosolated end products associated with diabetes mellitus  (+ info)

Why does renal artery stenosis cause Hypertension? What is the physiology?


Stenosis is when there is a constriction (narrowing) of the renal artery, so the blood needs to work harder to push thru the part where the stenosis is. When the heart is working harder to push the blood thru it raises your BP.  (+ info)

which of the following is the correct code for secondary malignant hypertension due to renal embolism?


a) 405.01
b) 405.11
c) 405.09
d) 405.19

What's the safest class of antihypertensive in near end stage chronic renal failure?


Person with hypertension (eg. BP of 170/110 persistently elevated) and close to end stage chronic renal disease (say eGFR of <15). Waiting for dialysis. Meanwhile, what class (or combination of classes) of antihypertensive is/are safest to use?

Thanks.
----------

This would be better discussed with the person's physician. But suspect Beta Blocker would be safest.  (+ info)

What if an accessory renal artery can't be stented?


If the accessory renal artery is too long and flat but is causing hypertension, what is usually done?
----------

Surgery

• Two surgical procedures that your physician may use to treat renal artery stenosis are endarterectomy and surgical bypass.

• In a renal endarterectomy, a vascular surgeon removes the inner lining of your renal artery, which contains the plaque. This removes the plaque and leaves a smooth, wide-open artery.

• Bypass surgery creates a detour around the narrowed or blocked sections of your renal artery.

• To create this bypass, a vascular surgeon connects one of your veins or a tube made from man-made materials above and below the area that is blocked. This creates a new path for your blood to flow to your kidneys.

• The choice of the procedure that is best for your situation depends upon the extent and location of the blockages
