To investigate the percutaneous endovascular management of visceral aneurysms (VA) and visceral pseudoaneurysms (VPA) treated in three European interventional radiology departments. Patient archives from the department’s databases were examined and retrospectively analyzed. Patients diagnosed between 2000 and 2010 with VA and/or VPA, confirmed by computed(More)
The purpose of this study was to describe and evaluate the findings of unenhanced ultrasonography (US) and contrast-enhanced ultrasonography (CEUS) when these modalities are applied during transarterial embolization (TAE) or transarterial chemoembolization (TACE) of liver tumors. Sixteen tumors (9 hepatocellular carcinomas, 5 metastases from colorectal(More)
To evaluate the limitations and the feasibility of contrast-enhanced ultrasonography (CEUS) for the assessment of tumor response shortly after transarterial chemoembolization (TACE). Fifty seven patients (41 patients with hepatomas, 16 patients with metastases) were studied with CEUS before, 1 day after, and 30 days after TACE. A CEUS-efficiency score(More)
To report the immediate and long-term outcomes following the fluoroscopically guided balloon dilatations performed in our department for the treatment of achalasia. We reviewed retrospectively all patients that underwent a fluoroscopically guided balloon dilatation because of achalasia in our department between April 2007 and September 2010. The follow-up(More)
AIM To evaluate the response of hepatocellular carcinoma (HCC) to transarterial chemoembolization (TACE) using a simplified protocol of parametric contrast-enhanced ultrasound (pCEUS). METHODS Eighteen patients with HCC (18 target tumors, diameter: 2.8-12 cm) were evaluated before, and 20 d after TACE. The distribution and morphology of TACE-induced(More)
AIMS To evaluate the sonographic changes observed in hepatocellular carcinoma (HCC) post antiangiogenic treatment with sorafenib. PATIENTS AND METHODS Twenty one intermediate or advanced HCC patients (19 men, 2 women; mean age: 66.8 years; 32 target tumors-TTs) received sorafenib as monotherapy and were studied with unenhanced ultrasonography (US) and(More)
OBJECTIVES/BACKGROUND The increased complexity of endovascular aortic repair necessitates longer procedural time and higher radiation exposure to the operator, particularly to exposed body parts. The aims were to measure directly exposure to radiation of the bodies and heads of the operating team during endovascular repair of thoracoabdominal aortic(More)
OBJECTIVE The purpose of this study was to investigate the immediate and long-term outcomes after fluoroscopically guided balloon dilation of esophageal strictures in a series of patients with dystrophic epidermolysis bullosa (DEB). MATERIALS AND METHODS Between 2005 and 2011, the medical records of all patients with DEB treated with fluoroscopically(More)
The authors report the use of the ‘lasso technique’ for the preservation of bilateral renal artery patency, following the intraoperative proximal migration of an aortic endograft with suprarenal bare metal fixation and anchoring barbs, due to device delivery failure.During an emergency endovascular repair of a ruptured mycotic abdominal aortic aneurysm(More)
OBJECTIVES Spinal cord ischaemia (SCI) following endovascular thoracoabdominal aortic aneurysm (TAAA) repair is a devastating and unpredictable complication. This study describes a single unit's experience of SCI in patients who have had endovascular TAAA repair. METHODS A prospectively maintained database of patients having endovascular TAAA repair using(More)
