1 Apply direct pressure until the bleeding stops. 2  Cover the injury with a sterile dressing shaped to the contour of the ear, and tape it loosely in place. 3  Apply cold compresses over the dressing to reduce pain and swelling.  If part of the ear has been cut off, keep the part.
The retroaortic or circumaortic renal vein may be compressed between the aorta and the vertebral body, which is called posterior nutcracker [8] and [12]. The clinical features of NP or posterior NP vary from asymptomatic microhematuria to severe pelvic congestion [8].
Components [edit]. The aortic root is the portion of the ascending aorta beginning at the aortic annulus and extending to the sinotubular junction. Between each commissure of the aortic valve and opposite the cusps of the aortic valve, three small dilatations called the aortic sinuses.t the union of the ascending aorta with the aortic arch the caliber of the vessel is increased, owing to a bulging of its right wall. This dilatation is termed the bulb of the aorta, and on transverse section presents a somewhat oval figure.
