[A patient with aortic dissection and abdominal aortic aneurysm with fistula].
Aneurysm of the abdominal aorta is not uncommon in later life. The frequency of aneurysm rupture varies with aneurysm diameter. In rare cases, the aneurysm may rupture intra-abdominally into surrounding structures and give rise to a fistula. When blood vessels are involved, the commonest form is aortocaval fistula, the presenting symptoms being those of severe right-ventricular heart failure. Although thoracic aorta dissection may be made manifest in acute intense chest pain, it is asymptomatic in up to 50 per cent of cases. The article consists in a case report of asymptomatic thoracic aorta dissection occurring concomitantly with a ruptured abdominal aneurysm the symptoms of which were severe right ventricular heart failure due to an aortocaval fistula causing increased pressure, and severe bilateral oedema of the legs. If the rare complication of an aortocaval fistula could be detected earlier, it might be possible to prevent progression to refractory cardiac failure. The possibility of a fistula should be borne in mind if haematuria is present in a case of abdominal aneurysm or a pulsatile abdominal mass is present in conjunction with a murmur.
