Abstract
Kidneys are retroperitoneal organs that play an important role in maintaining normal internal environment of the body. Each kidney is supplied by a single renal artery that arises from the lateral aspect of the aorta at L2 level with the right renal artery lower and higher in origin than left renal artery.
Atherosclerotic renal artery stenosis is the most common pathology affecting renal arteries, although, FMD, arteritis and other autoimmune diseases can also affect renal arteries.
Renal artery is evaluated by many imaging methods including Doppler ultrasound, MRA, CTA and DSA, arranger from least to most invasive techniques. DSA is the gold standard of RA assessment; however, being invasive results in receding role in RA imaging.
Our study was conducted to evaluate renal artery affection in diabetes mellitus and atherosclerosis patients. 50 patients were included in the study.
Informed written consent was obtained prior to participation in the study from all patients. Renal functions were assessed to exclude patients with renal impairment. 80—100 mL of non-ionic iodinated contrast material (Iopromid; Ultravist 370® mgI/mL, Schering AG, Germany) was administered. This was followed by 20-30 ml bolus of saline.
MDCT scan parameters were as follows: tube voltage: 120 kV; tube current: 200—440 mAs; collimation: 16 × 0.65 mm; gantry rotation time: 400 msec; slice thickness: 1 mm; slice interval: 1 mm. Post imaging processing included MIP and VR for each patient and was reviewed for detection.
Results were analysed using computer program IBM SPSS software version 20.0.
Our study revealed a significant correlation between atherosclerosis and diabetes and renal artery affection.
We recommend CTA for evaluation and screening for renal arteries affection in patients with atherosclerosis and diabetes. It is safe, non-invasive and accurate in diagnosis of renal arteries affection either uni or bilateral.
