PURPOSE: Covered stents have been demonstrated to reduce restenosis; however, the membrane's limited biocompatibility can still lead to thrombus formation. To obtain optimal surface hemocompatibility, endothelialization of the luminal surface has been proposed. However, the effect of delivery procedures, such as crimping and balloon dilatation, on the endothelial layer has not been quantified. This study investigated the impact of such procedures on endothelialized covered stents in vitro...

PURPOSE: Transjugular intrahepatic portosystemic shunts (TIPS) were historically placed using uncovered bare-metal stents. Current practice has now shifted toward the use of polytetrafluoroethylene (PTFE)-covered stents, given the improved primary patency seen with these stents. The aim of this study was to determine whether there is any added value, such as overall survival or stent patency, when using covered stents versus uncovered stents in TIPS placement in a large cohort. MATERIALS AND METHODS: From April 1995 to June 2012, a total of 744 consecutive adult patients underwent de novo TIPS placement (378 receiving uncovered stents, 366 receiving covered stents)...

PURPOSE: Hepatic metastasis from melanoma represents a therapeutic dilemma, with limited effective options for the 85% of cases deemed unresectable. Systemic agents confer toxicity and, along with traditional local hepatic arterial-directed therapies such as transarterial chemoembolization, have not led to a significant increase in survival. The aim of this study was to investigate the safety and dose-limiting toxicity of DEBDOX for the treatment of unresectable hepatic metastases from melanoma...

Prostate artery embolization (PAE) has emerged as a new treatment option for patients with symptomatic benign prostatic hyperplasia. The main challenges related to this procedure are navigating arteries with atherosclerosis and anatomical variations, and the potential risk of non-target embolization to pelvic structures due to the presence of collateral shunts and reflux of microparticles. Knowledge of classical vascular anatomy and the most common variations is essential for safe embolization, good clinical practice, and optimal outcomes...

This case describes a technique used to close a long-term 14F transpleural biliary drainage catheter tract to prevent biliopleural fistula and further complications. We deployed a compressed gelatin foam pledget provided in a pre-loaded delivery device (Hep-Plug™) along the intrahepatic tissue tract for sealing it against the pleural cavity. The device used is easy to handle and gives the Interventional Radiologist the possibility to safely manage and prevent complications after percutaneous transhepatic interventions...

PURPOSE: To develop a model to predict successful bilirubin decrease following percutaneous biliary drain placement. METHODS: A total of 257 patients who were identified having undergone percutaneous transhepatic biliary drain placement (PTBD) at our institution between 2002 and 2013 had their medical records and imaging reviewed. Of those, 190 of these patients met criteria and were used in the analysis. A regression model was performed on logarithm-transformed collected variables to predict post-drainage logarithmic transformed total bilirubin levels...

PURPOSE: To address the feasibility of prophylactic temporary occlusion of the cystic artery using a detachable coil during (90)Y radioembolization. MATERIALS AND METHODS: From January 2012 to October 2016, nine patients underwent temporary occlusion of the cystic artery during (90)Y radioembolization. Based on the planning hepatic angiography, a detachable coil was deployed into the cystic artery, which arose from a more distal level (e.g., right anterior hepatic artery) than its usual origin, but the proximal 1 cm was left inside the microcatheter...

PURPOSE: Radiation safety and protection are a key component of fluoroscopy-guided interventions. We hypothesize that providing weekly personal dose feedback will increase radiation awareness and ultimately will lead to optimized behavior. Therefore, we designed and implemented a personalized feedback of procedure and personal doses for medical staff involved in fluoroscopy-guided interventions. MATERIALS AND METHODS: Medical staff (physicians and technicians, n = 27) involved in fluoroscopy-guided interventions were equipped with electronic personal dose meters (PDMs)...

For a long time, radiation-induced skin injuries were only encountered in patients undergoing radiation therapy. In diagnostic radiology, radiation exposures of patients causing skin injuries were extremely rare. The introduction of fast multislice CT scanners and fluoroscopically guided interventions (FGI) changed the situation. Both methods carry the risk of excessive high doses to the skin of patients resulting in skin injuries. In the early nineties, several reports of epilation and skin injuries following CT brain perfusion studies were published...
