Clinical History

This 70-year-old man, with a history of mild gastroesophageal reflux, presented to Alfred Hospital with sudden onset of severe upper abdominal pain radiating to the left shoulder blade. On examination, he was anxious and hyperventilating, with a pulse of 87 beats/min and a blood pressure of 140/90 mm Hg. Abdominal examination revealed firm distension and decreased bowel sounds. Emergency laparotomy revealed no evidence of organ distension; the pancreas appeared normal, but an unresolved abdominal aortic aneurysm was noted. Endoscopy was performed the following day, showing a ruptured esophageal ulcer, and a Celestin tube was inserted. The patient developed local inflammatory complications, pulmonary edema and congestion, and died 19 days after admission.

Pathology

The specimen represents the lower part of the abdominal aorta together with the common femoral vessels and the proximal fragments of the internal and external femoral arteries. A large 10 x 7 cm aneurysm is located below the origin of the renal arteries and extends to the bifurcation of the aorta. The aneurysm, with its severe thinning of the abdominal aortic wall, is partially covered by a laminated blood clot, indicating the chronicity of the process. A recent blood clot is present on the luminal surface. There appears to be aneurysmal dilatation of both the common femoral and (open) left external femoral arteries. The abdominal aorta in the upper part of the specimen shows numerous local ulcerating atherosclerotic plaques. There is no evidence of rupture.

Additional Information

Abdominal aortic aneurysm (AAA or triple A) is a localized dilation of the abdominal aorta (diameter >3 cm or more than 50% larger than normal). They are usually asymptomatic unless ruptured. Large aneurysms may be palpable on abdominal examination. Sometimes there may be abdominal, back, or leg pain, depending on the location and size. Rupture can cause abdominal or back pain, a sudden drop in blood pressure with loss of consciousness, and is often fatal. Abdominal aortic aneurysms are most common in people over 50 years of age, men, and those with a family history of the condition. Additional risk factors include smoking, high blood pressure, and other heart or blood vessel disease. Genetic abnormalities, including Marfan syndrome and Ehlers-Danlos syndrome, are also found. Abdominal aortic aneurysms are the most common type of aortic aneurysm, and about 85% occur below the kidneys.
