PINTO, Daniel Mendes et al. Iliac aneurysm associated with arteriovenous fistula. J. vasc. bras. [online]. 2007, vol.6, n.3, pp. 297-300. ISSN 1677-5449. http://dx.doi.org/10.1590/S1677-54492007000300016.
Rupture of aortoiliac aneurysms into the iliac vein or vena cava is an uncommon complication. Many signs and symptoms develop as a result of venous hypertension, which makes preoperative diagnosis difficult, such as leg edema, dyspnea, hematuria, signs of renal or cardiac insufficiency. Abdominal bruit, associated with pulsatile mass and abdominal pain, is the key for clinical diagnosis. Preoperative recognition of arteriovenous fistula is important for surgical planning. We report a case of right internal and common iliac artery aneurysm associated with fistula into the common iliac vein. Initial symptoms were right leg edema and dyspnea, which induced to the incorrect diagnosis of deep vein thrombosis.
