CARDIOVASCULAR AND INTERVENTIONAL RADIOLOGY. Early Stage Hepatocellular Carcinomas Not Feasible for Ultrasound-Guided Radiofrequency Ablation: Comparison of Transarterial Chemoembolization Alone and Combined Therapy with Transarterial Chemoembolization and Radiofrequency Ablation

Dongho Hyun, Sung Ki Cho, Sung Wook Shin, Kwang Bo Park, Hong Suk Park, Sung Wook Choo, Young Soo Do, In-wook Choo, Min Woo Lee, Hyunchul Rhim, Hyo Keun Lim

Purpose: To report the results of combined therapy with transarterial chemoembolization (TACE) and radiofrequency ablation (RFA) for early stage hepatocellular carcinoma (HCC) considered infeasible for ultrasound (US)-guided RFA in comparison with those of TACE monotherapy.

CARDIOVASCULAR AND INTERVENTIONAL RADIOLOGY. Mid-Term Vascular Safety of Renal Denervation Assessed by Follow-up MR Imaging

Axel Schmid, Raphael Schmieder, Michael Lell, Rolf Janka, Roland Veelken, Roland E. Schmieder, Michael Uder, Christian Ott

Background/Aims: Renal denervation (RDN) emerged as a treatment option for reducing blood pressure (BP) in patients with treatment-resistant hypertension (TRH). However, concerns have been raised regarding the incidence of late renal artery stenosis or thromboembolism after RDN. The goal of the current study was, therefore, to conduct a prospective clinical trial on the mid-term vascular integrity of the renal arteries and the perfusion of the renal parenchyma assessed by magnetic resonance imaging (MRI) in the follow-up after catheter-based RDN.

CARDIOVASCULAR AND INTERVENTIONAL RADIOLOGY. Unenhanced Cone Beam Computed Tomography and Fusion Imaging in Direct Percutaneous Sac Injection for Treatment of Type II Endoleak: Technical Note

Gianpaolo Carrafiello, Anna Maria Ierardi, Alessandro Radaelli, Giuseppe De Marchi, Chiara Floridi, Gabriele Piffaretti, Fontana Federico

Aim: To evaluate safety, feasibility, technical success, and clinical success of direct percutaneous sac injection (DPSI) for the treatment of type II endoleaks (T2EL) using anatomical landmarks on cone beam computed tomography (CBCT) and fusion imaging (FI).

CARDIOVASCULAR AND INTERVENTIONAL RADIOLOGY. An Endovascular Approach to the Entrapped Central Venous Catheter After Cardiac Surgery

Shamit S. Desai, Meghana Konanur, Gretchen Foltz, S. Chris Malaisrie, Scott Resnick

Purpose: Entrapment of central venous catheters (CVC) at the superior vena cava (SVC) cardiopulmonary bypass cannulation site by closing purse-string sutures is a rare complication of cardiac surgery. Historically, resternotomy has been required for suture release. An endovascular catheter release approach was developed.

CARDIOVASCULAR AND INTERVENTIONAL RADIOLOGY. Mid-Term Outcomes of Endovascular Treatment for TASC-II D Femoropopliteal Occlusive Disease with Critical Limb Ischemia

Álvaro Torres-Blanco, Gemma Edo-Fleta, Francisco Gómez-Palonés, Vicente Molina-Nácher, Eduardo Ortiz-Monzón

Purpose: The purpose of the study was to assess the safety and midterm effectiveness of endovascular treatment in Trans-Atlantic Inter-Society Consensus II (TASC-II) D femoropopliteal occlusions in patients with critical limb ischemia (CLI).

CARDIOVASCULAR AND INTERVENTIONAL RADIOLOGY. Initial Experience with Balloon-Occluded Trans-catheter Arterial Chemoembolization (B-TACE) for Hepatocellular Carcinoma

Mitsunari Maruyama, Takeshi Yoshizako, Tomonori Nakamura, Megumi Nakamura, Rika Yoshida, Hajime Kitagaki

Purpose: This study was performed to evaluate the accumulation of lipiodol emulsion (LE) and adverse events during our initial experience of balloon-occluded trans-catheter arterial chemoembolization (B-TACE) for hepatocellular carcinoma (HCC) compared with conventional TACE (C-TACE).

CARDIOVASCULAR AND INTERVENTIONAL RADIOLOGY. Clinical Results After Prostatic Artery Embolization Using the PErFecTED Technique: A Single-Center Study

Gregory Amouyal, Nicolas Thiounn, Olivier Pellerin, Lin Yen-Ting, Costantino Del Giudice, Carole Dean, Helena Pereira, Gilles Chatellier, Marc Sapoval

Background: Prostatic artery embolization (PAE) has been performed for a few years, but there is no report on PAE using the PErFecTED technique outside from the team that initiated this approach.

CARDIOVASCULAR AND INTERVENTIONAL RADIOLOGY. Can 1H MR Spectroscopy be Used to Assess the Success of Uterine Artery Embolisation?

Gillian Macnaught , G. Ananthakrishnan, L. Hinksman, R. Yadavali, F. Bryden, S. Lassman, M. Ritchie, K. Gallacher, C. Hay, J. G. Moss

Purpose: Absence of contrast on contrast enhanced MRI (CEMRI) and reduction in uterine volume at 6 months post-uterine artery embolisation (UAE) currently indicate the successful disruption of the fibroid blood supply by UAE. This study assesses whether 1H MR spectroscopy (1H MRS) can also indicate the success of UAE.

CARDIOVASCULAR AND INTERVENTIONAL RADIOLOGY. The Value of Rotational Venography Versus Anterior–Posterior Venography in 100 Consecutive IVC Filter Retrievals

Ryan M. Kiefer, Nirnimesh Pandey, Scott O. Trerotola, Gregory J. Nadolski, S. William Stavropoulos

Purpose: Accurately detecting inferior vena cava (IVC) filter complications is important for safe and successful retrieval as tip-embedded filters require removal with non-standard techniques. Venography prior to IVC filter retrieval has traditionally used a single anterior–posterior (AP) projection. This study compares the utility of rotational venography to AP venography prior to IVC filter removal.

CARDIOVASCULAR AND INTERVENTIONAL RADIOLOGY. Histogram Analysis of CT Perfusion of Hepatocellular Carcinoma for Predicting Response to Transarterial Radioembolization: Value of Tumor Heterogeneity Assessment

Caecilia S. Reiner, Sonja Gordic, Gilbert Puippe, Fabian Morsbach, Moritz Wurnig, Niklaus Schaefer, Patrick Veit-Haibach, Thomas Pfammatter, Hatem Alkadhi

Purpose: To evaluate in patients with hepatocellular carcinoma (HCC), whether assessment of tumor heterogeneity by histogram analysis of computed tomography (CT) perfusion helps predicting response to transarterial radioembolization (TARE).
