Cephalic arch stenosis in autogenous haemodialysis fistulas: treatment with the viabahn stent-graft.

Purpose: Cephalic arch stenosis (CAS) is an important and common cause of dysfunction in autogenous haemodialysis fistulas that requires multiple reinterventions and aggressive surveillance. We evaluated the safety and efficacy of the Viabahn stent-graft for the management of CAS.

Methods: Between April 2005 and October 2011, 11 consecutive patients [four men and seven women (mean age 56.

Perforation and abscess formation after radiological placement of a retrievable plastic biliary stent.

Introduction: Retrievable plastic biliary stents are usually inserted endoscopically. When endoscopic placement fails, radiological percutaneous transhepatic placement is indicated. We report the occurrence of a case of delayed duodenal perforation with abscess formation after radiological placement of a plastic stent.

Combined percutaneous radiofrequency ablation and ethanol injection of renal tumours: midterm results.

Objectives: To evaluate the safety and efficacy of combined percutaneous, image-guided, radiofrequency (RF) ablation and ethanol injection of renal tumours, and to present our midterm results.

Methods: Since February 2002, 27 consecutive patients (22 men, 5 women; age range: 39-84 yr; mean: 69) with 28 renal tumours (mean diameter: 2.87cm) were treated with combined percutaneous RF and ethanol ablation, and were prospectively evaluated.
