A 74-year-old patient was admitted to our department in a serious general c
ondition due to massive bleeding. He had been treated 10 years previously i
n another hospital with an aorto-bifemoral bypass for obstructive disease u
sing a knitted-Dacron graft. A large pulsating mass was present in the righ
t iliac fossa as well as enormous pulsating enlargement of the scrotum. Ech
o color-Doppler investigation detected dilation up to 5 cm in diameter of t
he right branch of the graft and a large perigraft hematoma communicating w
ith a similar mass in the scrotum. The patient was submitted to emergency s
urgery and a large rupture of the graft was found. The dilated segment was
resected and replaced by a new 8 mm Dacron graft. Postoperative course was
uneventful.
