An 82-year-old man was brought to our hospital because of vomiting and abdominal pain. Physical examination revealed a pulsating tumor on the left side of the abdomen. Abdominal CT showed an aneurysm of the aorta that was larger than fist size, and a retroperitoneal hematoma. The patient survived emergency laparotomy. The family history revealed that the patient had two brothers, an older brother and a younger brother, both of whom had been operated on for ruptured abdominal aortic aneurysm more than ten years previously in our hospital.
A review of the literature revealed the following, in brief. Familial abdominal aortic aneurysm accounts for 12-20 per cent of cases of abdominal aortic aneurysm in Western countries, but only five families have been reported in Japan. Familial cases are characterized by: 1, onset at younger age; 2, slight predominance in women; and 3, a high incidence of rupture. Routine ultrasonography screening of first-degree relatives of patients with an abdominal aortic aneurysm is recomended.
