CARDIOVASCULAR AND INTERVENTIONAL RADIOLOGY. Predicting Treatment Response of Colorectal Cancer Liver Metastases to Conventional Lipiodol-Based Transarterial Chemoembolization Using Diffusion-Weighted MR Imaging: Value of Pretreatment Apparent Diffusion Coefficients (ADC) and ADC Changes Under Therapy

Maximilian Lahrsow, Moritz H. Albrecht, Matthew W. Bickford, Thomas J. Vogl

Purpose: To use absolute pretreatment apparent diffusion coefficients (ADC) derived from diffusion-weighted MR imaging (DWI) to predict response to repetitive cTACE for unresectable liver metastases of colorectal carcinoma (CRLM) at 1 and 3 months after start of treatment.

CARDIOVASCULAR AND INTERVENTIONAL RADIOLOGY. Anesthesia Practices for Interventional Radiology in Europe

Alessandra Vari, Afshin Gangi

Purpose: The Cardiovascular and Interventional Radiological Society of Europe (CIRSE) prompted an initiative to frame the current European status of anesthetic practices for interventional radiology, in consideration of the current variability of IR suite settings, staffing and anesthetic practices reported in the literature and of the growing debate on sedation administered by non-anesthesiologists, in Europe.

CARDIOVASCULAR AND INTERVENTIONAL RADIOLOGY. Endovascular Treatment Strategy Using Catheter-Directed Thrombolysis, Percutaneous Aspiration Thromboembolectomy, and Angioplasty for Acute Upper Limb Ischemia

Tatsuo Ueda, Satoru MurataIzumi Miki, Daisuke Yasui, Fumie Sugihara, Hiroyuki Tajima, Tetsuro Morota, Shin-Ichiro Kumita

Purpose: To evaluate the usefulness and safety of endovascular treatments for acute upper limb ischemia (AULI) by using multiple techniques, and to compare catheter-directed thrombolysis (CDT) and percutaneous aspiration thromboembolectomy (PAT) as initial procedures.

CARDIOVASCULAR AND INTERVENTIONAL RADIOLOGY. Safety and Efficacy of Sodium Tetradecyl Sulfate and Lipiodol Foam in Balloon-Occluded Retrograde Transvenous Obliteration (BRTO) for Large Porto-Systemic Shunts

Amar Mukund, Ganesh Deogaonkar, S. Rajesh, Saggerre Muralikrishna Shasthry, Shiv Kumar Sarin

Objective: To evaluate the safety and efficacy sodium tetradecyl sulfate and lipiodol foam (STS foam) in BRTO for large (caliber >=15 mm) porto-systemic shunt and gastric fundal varices.

CARDIOVASCULAR AND INTERVENTIONAL RADIOLOGY. Validation of the Risk Prediction Models STATE-Score and START-Strategy to Guide TACE Treatment in Patients with Hepatocellular Carcinoma

Aline Mähringer-Kunz, Roman Kloeckner, Michael B. Pitton, Christoph Düber, Irene Schmidtmann, Peter R. Galle, Sandra Koch, Arndt Weinmann

Purpose: Several scoring systems that guide patients’ treatment regimen for transarterial chemoembolization (TACE) of hepatocellular carcinoma (HCC) have been introduced, but none have gained widespread acceptance in clinical practice. The purpose of this study is to externally validate the Selection for TrAnsarterial chemoembolization TrEatment (STATE)-score and START-strategy [i.e., sequential use of the STATE-score and Assessment for Retreatment with TACE (ART)-score].

CARDIOVASCULAR AND INTERVENTIONAL RADIOLOGY. Occurrence of Vascular Lake Phenomenon as a Predictor of Improved Tumor Response in HCC Patients That Underwent DEB-TACE

Rafael Noronha Cavalcante, Felipe Nasser, Joaquim M. Motta-Leal-Filho, Breno B. Affonso, Francisco L. Galastri, Bruna De Fina, Rodrigo G. Garcia, Nelson Wolosker

Purpose: To evaluate incidence and predictive factors for the vascular lake phenomenon (VLP), as well as to compare local and overall tumor response in patients with and without VLP induced during DEB-TACE for HCC.

CARDIOVASCULAR AND INTERVENTIONAL RADIOLOGY. Is it Time for a Specific Undergraduate Interventional Radiology Curriculum?

Zaid Alsafi, Vamsee Bhrugubanda, Sanjeev Ramachandran, Ali Alsafi, Mohamad Hamady

Purpose: Interventional radiology (IR) is traditionally underrepresented in undergraduate medical curricula. Final-year medical students ought to be familiar with some common IR procedures in order to make adequate referrals and work-up patients appropriately. We evaluated the knowledge of final-year medical students on common IR procedures and compared it with their knowledge of other specialties.

CARDIOVASCULAR AND INTERVENTIONAL RADIOLOGY. A Novel Self-Expandable, Radioactive Airway Stent Loaded with 125I Seeds: A Feasibility and Safety Study in Healthy Beagle Dog

Yong Wang, Jin-He Guo, Guang-Yu Zhu, Hai-Dong Zhu, Li Chen, Jian Lu, Chao Wang, Gao-Jun Teng

Purpose: Airway stent placement is an effective treatment for the immediate palliation of malignant airway obstruction. However, restenosis caused by tumor ingrowth and/or overgrowth after stenting is common. The purpose of this study was to investigate the feasibility and safety of a novel self-expandable stent loaded with 125I seeds in healthy beagle dog.
