    Department of Radiology, Section of Interventional Radiology, Robert H. Lurie Comprehensive Cancer Center, Northwestern Memorial Hospital, 676 N. St. Clair, Suite 800, Chicago, IL, 60611, USA.
    Purpose: To investigate the association between pretransplant intra-arterial liver-directed therapy (IAT) for hepatocellular carcinoma (HCC) and hepatic arterial complications (HAC) in orthotopic liver transplantation (OLT) [namely hepatic artery thrombosis (HAT) and/or the need for hepatic arterial conduit].

    Methods: A total of 175 HCC patients (mean age: 60 years) underwent IAT with either transarterial chemoembolization or yttrium-90 (90Y) transarterial radioembolization prior to OLT between 2003 and 2013. A matched control cohort of 159 HCC patients who underwent OLT without prior IAT was selected. Read More

    Vascular and Oncological Interventional Radiology, Hôpital Européen Georges Pompidou, Université Paris Descartes Paris Cité Sorbonne, 20 Rue Leblanc, 75015, Paris, France.
    Purpose: To compare outcomes of percutaneous robot-assisted uterine fibroid embolization (UFE) using two different endovascular robotic catheters.

    Methods: Twenty-one patients with a symptomatic uterine fibroid were prospectively enrolled in a single-center study to be treated with a percutaneous robot-assisted embolization using the Magellan system. Fourteen patients were treated using a first generation steerable robotic catheter, version 1. Read More

    Survival Analysis of Advanced HCC Treated with Radioembolization: Comparing Impact of Clinical Performance Status Versus Vascular Invasion/Metastases.

    Section of Interventional Radiology, Department of Radiology, Northwestern Memorial Hospital, Robert H. Lurie Comprehensive Cancer Center, Chicago, IL, USA.
    Purpose: In this study, we aim to compare the effects of prognostic indicators on survival analysis for Barcelona Clinic Liver Cancer (BCLC) C patients undergoing yttrium-90 radioembolization (Y-90).

    Methods: A prospectively acquired database (2003-2017) for BCLC C hepatocellular carcinoma (HCC) patients that underwent radioembolization with Y-90 was searched. The criteria for BCLC C status (Eastern Cooperative Oncology Group (ECOG) performance status (PS) of 1 or 2, metastases, and/or portal vein thrombosis (PVT)) were recorded. Read More

    Experiments for the Development of a Steerable Microcatheter.
    Cardiovasc Intervent Radiol 2017 Dec 6;40(12):1921-1926. Epub 2017 Sep 6.
    Sumitomo Bakelite Co., Ltd, 2-5-8 Higashishinagawa, Shinagawa-ku, Tokyo, 140-0002, Japan.
    Purpose: Sumitomo Bakelite has developed a steerable microcatheter with a mechanism on the handle for changing the direction of the catheter tip. Experiments were conducted in an animal model to evaluate the practicality of the catheter with the goal of introduction into clinical use.

    Materials And Methods: The steerable microcatheter has the following specifications: external diameter 2. Read More
