Early stage of abdominal aortic coarctation mainly manifests as chest and abdominal pain, lower limbs and visceral ischemia.
1. Pain: Early stage of abdominal aortic coarctation mainly manifests tear-like pain in the chest and back, which can be radiated to the back of the shoulder, interscapular area as well as the abdomen, lower limbs and other places.
2. Lower limb ischemia: aortic coarctation involving the abdominal aorta can be manifested as coldness and cyanosis of the lower limbs, numbness, pain and weakness of the legs, and weakening or disappearance of the pulse in the lower limbs.
3. Visceral ischemia: if the aortic coarctation involves the renal artery, there may be low back pain, hematuria, oliguria or anuria, etc.; the involvement of the superior mesenteric artery may lead to intestinal necrosis, resulting in abdominal pain; the involvement of the hepatic artery will have jaundice and other manifestations.
Early clinical manifestations depend on the location, extent and degree of involvement of abdominal aortic coarctation, etc. Late symptoms of cardiovascular system and rupture of the coarctation aneurysm may occur.
Abdominal aortic coarctation is a critical disease and should be treated as soon as it is detected to avoid serious consequences.
