Angioarchitectonic variants of adrenal glands
This study reviews individual anatomic variability of suprarenal arteries and veins in humans that were performed on 90 cadaveric adrenal glands. Superior (100%), middle (41,1%) and inferior (91,1%) suprarenal arteries were sub- divided into main, accessory and aberrant ones according to its source. On the grounds of ramification and number of trunks we also identified monopodial, dichotomous, terminal and solitary, supernumerary suprarenal arteries. Venous architecture and linear parameters were investigated in relations with inferior phrenic vein, inferior vena cava, renal and accessory hepatic veins. Results show variations in the drainage of central and peripheral adrenal veins were de- pended on adrenal gland topography and its venous surroundings. Unusual central adrenal vein patterns (duplication of central vein and aberrant opening) were seen in 17,8% on both sides. Peripheral adrenal veins arise at the level be- tween medulla and cortex by the intramural tributaries. They are classified into paraportal, superior, medial and in- ferior sectors according to their venous collector. These variations of adrenal veins play an important part in surgical treatment of adrenal disorders.
