Epithelioid hemangioendothelioma (EHE) is an extremely rare vascular tumor of intermediate malignancy. Generally it develops from the peripheral veins (usually the femoral vein). We report on a case of EHE of the radial artery, developed in a 26-year-old male patient, which presented as a solitary painless mass. He had a complete resection of the tumor and(More)
This paper focuses on the diagnostic value of CEUS in the detection and characterization of endoleaks in comparison with other imaging modalities, primary CDUS and CTA in the follow-up of endovascular abdominal aortic aneurysm repair. CEUS is an interesting alternative technique because of its limited costs and lack of exposure to ionizing radiation.(More)
INTRODUCTION Injury to the subclavian and axillary arteries is uncommon. Standard surgical techniques require wide exposure and dissection in traumatised areas which is often challenging and associated with significant morbidity, and mortality ranges from 5 to 30%. We report our experience with the endovascular treatment of these injuries. METHODS We(More)
The purpose of the study was to assess the effectiveness of contrast-enhanced ultrasonography (CEUS) in endoleak classification after endovascular treatment of an abdominal aortic aneurysm compared to computed tomography angiography (CTA). From May 2001 to April 2003, 10 patients with endoleaks already detected by CTA underwent CEUS with Sonovue® to confirm(More)
This study evaluated the safety and technical and clinical success rates of positioning endovascular endografts (EG) in ruptured abdominal aneurysms. Patients with a ruptured abdominal aortic aneurysm confirmed by contrastenhanced computed tomography angiography (CTA) were eligible for the analysis. Of 67 patients, 42 (62.7%) were treated with EG. Thirteen(More)
We report our experience of endovascular repair of isolated iliac artery aneurysms using commercially available stent grafts (SGs). Twenty-five patients (mean age 71 +/- 7 years) presented with 33 isolated iliac artery aneurysms (common iliac artery n = 29, external iliac artery n = 4). Five patients were symptomatic. Depending on the proximal iliac neck(More)
BACKGROUND To update our experience with thoracic aortic stent-graft treatment over a 5-year period, with special consideration for the occurrence and management of complications. METHODS From December 2000 to June 2006, 52 patients with thoracic aortic pathologies underwent endovascular repair; there were 43 males (83%) and 9 females, mean age 63 +/- 19(More)
OBJECTIVES The continued advances in imaging and stent/stent-graft technology have considerably expanded the indications for endovascular approach also in vascular trauma. We report our institutional experience with endovascular treatment of peripheral arterial injuries after blunt trauma. METHODS Between January 2000 and June 2006 out of a series of 81(More)
Surgical revascularization of the left subclavian artery (LSA) has been performed to warrant arm perfusion and to prevent paraplegia during thoracic stent graft (SG) procedures. We retrospectively investigated the outcome after intentional occlusion of the left subclavian artery during SG repair for thoracic aortic diseases. From December 2000 to June 2005,(More)
Percutaneous closure devices have been used to obtain rapid hemostasis and early mobilization of the patient after arterial catheterization. However, we observed challenging problems with the sealing procedure that require further surgical intervention. The present report is a retrospective analysis of the patterns of injury and the final outcome of four(More)
