We noticed that the primary division was a dorsal (D) and a ventral (V) branch of renal arteries
. This finding has been reported in some mammals [2, 11, 30].
Renal vasculature can show various patterns of aberrant renal arteries
which are usually due to abnormal rotation or position of kidney.10,11 Superior renal polar arteries are usually single and arise from aorta or renal arteries
.5 In this report, there were 3 superior extra-hilar branches arising from renal artery showing a rare pattern.
The renal arteries
can also give rise to vessels that usually do not arise from them, as suprarenai arteries, gonadal arteries, pancreatic artery, hepatic artery and some of the colic arteries (WEBER et al., 2009).
These two techniques, especially pressure-wire measurements, allow the operator to assess the patient's renal arteries
before and during treatment to determine whether the intervention is having a meaningful effect.
Key words: Multiple renal arteries
, anastomoses, external iliac artery, renal transplant, colour doppler.
It was reported that patients with stenoses of the aorta extending across the renal arteries
posed special problems.
 Bude OR, Forauer RA: Is it necessary to study accessory arteries when screening the renal arteries
for renovascular hypertension?
The operation (Figure 1) was carried out in the following stages: Control of the aneurysm was obtained by a clamp placed proximally to it, immediatly below the renal arteries
. The internal and external iliac arteries were exposed, isolated and controlled.
Techniques that use cardiac gating are viewed in cine mode to simulate the flow of blood in the renal arteries
during the cardiac cycle.
The patient underwent aortography the following day and on selective angiography the renal arteries
were found to be widely patent.
The resistive index of renal arteries
is the most widely used parameter to estimate the arteriolar vascular resistance and to evaluate renal haemodynamics.
