<unk>  location The vast majority of<unk> s are asymptomatic. However, as the<unk>  aorta expands and/or ruptures, the<unk>  may become painful and lead to pulsating sensations in the abdomen or pain in the chest, lower back, legs, or scrotum. Complications The complications include rupture, peripheral embolization, acute<unk>  occlusion, and<unk> aval (between the aorta and inferior vena cava) or aortoduodenal (between the aorta and the duodenum) fistulae. On physical examination, a palpable and pulsatile<unk>  mass can be noted. Bruits can be present in case of renal or visceral arterial stenosis. The signs and symptoms of a ruptured<unk>  may include severe pain in the lower back, flank, abdomen or groin. A mass that pulses with the heart beat may also be felt. The bleeding can lead to a hypovolemic shock with low blood pressure and a fast heart rate. This may lead to brief passing out. The mortality of<unk>  rupture is as high as 90 percent. 65 to 75 percent of patients die before they arrive at the hospital and up to 90 percent die before they reach the operating room. The bleeding can be retroperitoneal or into the<unk>  cavity. Rupture can also create a connection between the aorta and intestine or inferior vena cava. Flank ecchymosis (appearance of a bruise) is a sign of retroperitoneal bleeding, and is also called Grey Turner's sign.
