What is right renal artery aneurysm?
A renal artery aneurysm (RAA) is defined as a dilated segment of renal artery with a diameter that is more than twice the diameter of a normal renal artery. Symptomatic RAAs can cause hypertension, pain, hematuria, and renal infarction.
What is early bifurcation of renal artery?
Early branching vessels, also known as prehilar branches, arise less than 1.5–2.0 cm from the origin of the renal artery. Accessory renal arteries enter the renal hilum and may arise above or below the main renal artery. In contrast, polar arteries enter the kidney outside the hilum.
What do they do for a renal aneurysm?
RAAs can be repaired either with endovascular repair or open surgery. Endovascular repair is a minimally invasive procedure that’s done inside your blood vessels. This has advantages over open surgery, as there’s a lower risk of major adverse effects and shorter recovery time.
What is accessory renal artery?
An accessory renal artery (ARA) is a vestigial structure that forms during the ascent of the kidney from the pelvis to the lumbar region. 1. In the pelvis, the primitive kidney is supplied by vessels branching off the common iliac arteries.
How many right renal arteries are there?
two renal arteries
The kidneys filter waste and excess fluid from the blood. You have two renal arteries. The right renal artery supplies blood to the right kidney, while the left artery sends blood to the left kidney.
When should you intervene on a renal artery aneurysm?
Most aneurysms 1.5 to 2.0 cm and all those larger than 2.0 cm, regardless of blood pressure status, should be treated surgically if their anatomic character suggests a relatively noncomplex renal artery reconstruction and the procedure is undertaken by a surgeon experienced in renal artery interventions.
What happens if a renal aneurysm ruptures?
Severe hematuria resulting from rupture of the RAA into the renal pelvis is fortunately a rare event. Indications for treatment include hemorrhage, uncontrolled hypertension, pain, progressive enlargement, presence of an arteriovenous fistula, size > 2 to 2.5 cm, or > 1 cm in a female of childbearing age.
