Classically, a single renal artery arising from the abdominal aorta supplies the respective kidney on each side. Near the hilum of the kidney each renal artery divides into anterior and posterior branchs, which in turn divide into segmental arteries supplying the different renal segments...

Variations in the formation of the median nerve are of interest to anatomists,

radiologists, and surgeons. These variations may be vulnerable to damage in

surgical operations, but their knowledge also helps in the interpretation of

a nervous compression having unexplained clinical symptoms.

Preoperative knowledge of the presence of major venous anomalies facilitates the safe performance of aortic surgery. The purpose of the study was to estimate the incidence, as detected by abdominal computed tomography (CT), of major left renal vein anomalies related to the abdominal aorta in an adult population.

The aim of this study was to determine the prevalence of the different types of median nerve thenar motor branch and to compare them with literature data.

Variations of the thoracic arteries, including branches of the aortic arch, are interesting from an anatomical and embryological aspect [4, 8, 27, 32]. They are, however, more important for thoracic operations, especially in vascular, cardiac, oesophageal, and mediastinal surgery [1, 9, 12, 14, 34]. Modern radiological techniques, especially computerised tomographic angiography (CTA), magnetic resonance angiography (MRA), multislice CT (MSCT), and MSCT angiography, have enabled an elegant insight into the thoracic blood vessels [21, 27]. Obviously, the mentioned variations are also very important in radiological diagnostics and interventional radiology...
