CARDIOVASCULAR AND INTERVENTIONAL RADIOLOGY. Repetitive Blunt Trauma and Arterial Injury in the Hand

Geoffrey A. Gardiner Jr., Allison Tan

Purpose: Arterial injury in the hand is most often due to repetitive blunt trauma. Although not always associated with significant impairment, it may cause serious ischemic damage or considerable disability. As a cause of digital ischemia, the frequency of this disorder is widely under appreciated. This study reviews the clinical and angiographic features of this condition.

Shunsuke Sugawara, Yasuaki Arai, Miyuki Sone, Hitoshi Katai

Purpose: To clarify the frequency, severity, and risk factors for acute pancreatitis after percutaneous biliary stent placement across the papilla of Vater for malignant biliary obstruction.

CARDIOVASCULAR AND INTERVENTIONAL RADIOLOGY. Limited Post-observation Period in Pediatric Outpatient Ultrasound-Guided Liver Biopsies

Shireen Hayatghaibi, Daniel Ashton, Heather Cleveland, Kamlesh Kukreja

Purpose: We retrospectively studied whether a limited 2 h post-biopsy observation period after a percutaneous outpatient ultrasound-guided liver biopsy is a sufficient monitoring period for children.

Purpose: To evaluate whether a new electrode embedded with an electromagnetic position sensor (EMPS) improves the technical feasibility of percutaneous radiofrequency ablation (RFA) in patients with hepatic tumors difficult to place an electrode under ultrasonography (US) guidance and to assess short-term therapeutic efficacy and safety.

CARDIOVASCULAR AND INTERVENTIONAL RADIOLOGY. Safety and Efficacy of Transarterial Radioembolisation in Patients with Intermediate or Advanced Stage Hepatocellular Carcinoma Refractory to Chemoembolisation

Elisabeth G. Klompenhouwer, Raphaëla C. Dresen, Chris Verslype, Annouschka Laenen, Gert De Hertogh, Christophe M. Deroose, Lawrence Bonne, Vincent Vandevaveye, Geert Maleux

Introduction: Transarterial chemoembolisation (TACE) is the most widely used locoregional treatment for patients with an unresectable hepatocellular carcinoma (HCC). Transarterial radioembolisation (TARE) with yttrium-90 containing microspheres is an emerging interventional treatment that could be complementary or an alternative to TACE.

CARDIOVASCULAR AND INTERVENTIONAL RADIOLOGY. Endovascular Management of Malignant Inferior Vena Cava Syndromes

Daniel Kuetting, Daniel Thomas, Kai Wilhelm, Claus C. Pieper, Hans H. Schild, Carsten Meyer

Purpose: Malignant obstructions of the inferior vena cava (IVC) are a common cause of the IVC syndrome. As reports on interventional treatment of malignant inferior caval obstructions are very sparse, the purpose of this study was to retrospectively assess the outcome of endovascular treatment of symptomatic, malignant IVC syndromes.

CARDIOVASCULAR AND INTERVENTIONAL RADIOLOGY. Duplex Ultrasound Versus Clinical Surveillance in the Prediction of TIPS Malfunction Placed for Refractory Ascites: Is Ultrasound Surveillance Useful?

Shamar Young, Patrick Scanlon, Prashant Sherestha, Jafar Golzarian, Tina Sanghvi

Purpose: Since the advent of expanded polytetrafluoroethylene-covered stents and the improved patency they confer for transjugular intrahepatic portosystemic shunt (TIPS), the need to perform ultrasound surveillance has been debated. Prior reports have failed to separately evaluate patients who had TIPS placed for refractory ascites and variceal bleeding. The difference in morbidity from TIPS malfunction between these cohorts argues for distinction between the two. This retrospective review aims to determine whether Duplex ultrasound or return of symptoms more accurately predicts TIPS dysfunction.
