Iliac aneurysm symptoms

Iliac artery aneurysms behave similar to abdominal aortic aneurysms with symptoms related to aneurysm expansion including pain from arterial wall stretching, or compression and erosion of surrounding structures. Compressive symptoms of iliac artery aneurysm can involve the lower urinary tract (eg, ureteric colic, ureteral obstruction, pyelonephritis, urinary retention), lower gastrointestinal tract (eg, pain with defecation, tenesmus and constipation), or lumbar/pelvic nerves (paresthesia, sciatic neuralgia).
