Abstract:
A 72-year-old man suffering from congestive heart failure, swelling of the lower limbs and hematuria was transferred from another hospital with a diagnosis of large aneurysms of the abdominal aorta and the left common iliac artery. Iliac arteriovenous fistula (AVF) was definitively diagnosed preoperatively by contrast-enhanced CT and angiogaphy. At operation, an infrarenal abdominal aortic aneurysm of 8cm and left iliac arterial aneurysm of 12cm were identified. After proximal and distal aortic clamping, the aneurysm was entered and an AVF orifice of 1cm communicating with the left common iliac vein was disclosed at the right posterior wall of the left common iliac artery. Venous blood reflux was controlled by inserting an occlusive balloon catheter to the fistula and intraoperative shed blood was aspirated and returned by an autotransfusion system. The AVF was closed from inside the iliac aneurysm by three interrupted 3-0 monofilament mattress sutures with pledgets. The aneurysms were resected and replaced with a bifurcated Dacron prosthetic graft. The patient had an uncomplicated postoperative recovery; the lower limb edema subsided and heart failure improved rapidly. Preoperative identification of the location of the AVF is mandatory to make surgery safe. Moreover, easy availability or routine use of the devices for controlling undue blood loss such as an autotransfusion system and an occlusive balloon catheter are other important supplementary means to obtain good results of surgical treatment.
