[Isolated aneurysms of the iliac arteries]

Isolated aneurysms of the iliac arteries are rare. They must be considered as a disease pattern of their own as against aneurysms of the abdominal aorta because of the specific anatomical conditions in the pelvis. The clinical symptomatology is determined by their localisation and topographical relationships within the pelvis; this can give rise to problems in differential diagnosis primary urological, neurological or gastrointestinal diseases. The prognosis is decisively determined by early and correct diagnosis because of the danger of rupture. Sonography, computed tomography and angiography are indispensable aids in preoperative planning.
