Arterioenteric fistula is a rare cause of lower gastrointestinal bleeding, yet it can potentially cause massive, life-threatening bleeding. Patients with an advanced pelvic malignancy can develop hemorrhage from an arterioenteric fistula. Selective mesenteric angiography is unable to demonstrate the source of bleeding in these patients, so evaluation of the iliac arteries is essential. We prese...

INTRODUCTION Branched iliac stent-grafts (bSG) have recently been developed in order to preserve internal iliac artery (IIA) flow in patients with aneurysmal or short common iliac arteries. The aim of this study is to evaluate a single-center experience with bSG for the IIA. METHODS Twenty-two male patients (70 (IQR 65-79) years old) underwent EVAR with 23 bSG (1 bilateral repair) between Sep...

PURPOSE To describe four patients with abdominal aortic aneurysm and bilateral common iliac artery aneurysms repaired by coil embolization of the ipsilateral internal iliac artery, aortouniiliac endograft extended to the ipsilateral external iliac artery, femorofemoral bypass grafting, and a contralateral external iliac to internal iliac stent graft to preserve pelvic perfusion. METHODS Four ...

OBJECTIVE To evaluate the outcomes of major vessel reconstruction as part of surgery to remove sarcomas. DESIGN Retrospective review. SETTING Tertiary academic medical center. PATIENTS Fourteen patients (10 female) with retroperitoneal or extremity sarcomas and major blood vessel involvement who underwent surgery to remove the tumor and had blood vessel reconstruction between 2003 and 200...

A 60-year-old man who 10 years earlier underwent replacement of a thoracoabdominal type B dissecting aortic aneurysm with a Dacron graft, was admitted for an 8 cm pseudoaneurysm involving the coeliac axis, the superior mesenteric artery (SMA) and the right renal artery, and a 3 cm pseudoaneurysm involving the left iliac arteries (Fig. 1). During the primary procedure, the coeliac axis, the SMA ...

PURPOSE We aimed to evaluate a standardized ultrasonography (US) algorithm for the visualization of pathologic para-aortic tissue in retroperitoneal fibrosis (RPF). MATERIALS AND METHODS Thirty-five patients with lumbar RPF of typical extent, as determined by abdominal magnetic resonance imaging, were included. Examinations were conducted using standardized abdominal US with axial sections ob...

In awake dogs, lactic acid was injected into the phrenic and deep circumflex iliac arteries to elicit the diaphragm and abdominal muscle metaboreflexes, respectively. At rest, injections into the phrenic or deep circumflex iliac arteries significantly increased mean arterial blood pressure 21 +/- 7% and reduced cardiac output 6 +/- 2% and blood flow to the hindlimbs 20 +/- 9%. Simultaneously, t...

Acute total occlusion of the aorta is a rare and clinically critical condition requiring aggressive immediate diagnosis and treatment. A 73-year-old male was seen at our hospital complaining of pain sensation in both legs. Under the likely impression of an acute total occlusion of the aorta, emergency abdominal aortogram was done, which revealed total occlusion of the distal aorta and both ilia...

PURPOSE To present our experience using the Amplatzer vascular plug in various arterial and venous systems, and follow-up results. MATERIALS AND METHODS Between May 2005 and October 2006, 20 Amplatzer vascular plugs were used to achieve occlusion in 20 vessels in 12 patients (10 male, 2 female) aged between 24 and 80 years (mean age, 55 years). Localization and indications for embolotherapy w...
