[Ruptured aortoiliac aneurysm with AV-fistula].

HISTORY AND ADMISSION FINDINGS: A 65-year-old man presented an acute swelling of the left leg as the main sign. A pulsatile bruit could be auscultated over the abdomen.

INVESTIGATIONS: Doppler ultrasound suggested an aortic aneurysm with fistula. Dynamic bolus-triggered computed tomography demonstrated an aortoiliac aneurysm with a fistula into the confluence of the common iliac veins.

TREATMENT AND COURSE: An aorto-iliac graft was inserted surgically and and the patient recovered well.

CONCLUSION

In patients with an acute swelling of a lower limb an aorto-iliac aneurysm, though a rare cause, should be considered.
