    Multiple Enlarged Aneurysms in Primary Racemose Hemangioma of the Bronchial Artery: Successful Prophylactic Transcatheter Arterial Embolization Using N-butyl-2-cyanoacrylate and Coils.
    Cardiovasc Intervent Radiol 2018 Jan 17. Epub 2018 Jan 17.
    Department of Radiology, Chiba University Hospital, 1-8-1, Inohana, Chuo-ku, Chiba City, Chiba, 260-8677, Japan.
    An asymptomatic 48-year-old man presented with multiple aneurysms in a primary racemose hemangioma of the right bronchial artery. Bronchial arteriography revealed a tortuous artery with four fusiform aneurysms of varying sizes and aneurysmal dilatation with marked thrombus formation in the long segment of the distal portion. Because the tip of catheter could not pass beyond the aneurysmal dilatation, we performed balloon-occluded embolization using a mixture of N-butyl-2-cyanoacrylate (NBCA) and iodized oil. Read More

    Arms Down Cone Beam CT Hepatic Angiography Performance Assessment: Vascular Imaging Quality and Imaging Artifacts.
    Cardiovasc Intervent Radiol 2018 Jan 11. Epub 2018 Jan 11.
    Department of Radiology, Interventional Radiology Service, Memorial Sloan Kettering Cancer Center, 1275 York Avenue, New York, NY, 10065, USA.
    Introduction: The practice of positioning patients' arms above the head during catheter-injected hepatic arterial phase cone beam CT (A-CBCT) imaging has been inherited from standard CT imaging due to image quality concerns, but interrupts workflow and extends procedure time. We sought to assess A-CBCT image quality and artifacts with arms extended above the head versus down by the side.

    Methods: We performed an IRB approved retrospective evaluation of reformatted and 3D-volume rendered images from 91 consecutive A-CBCTs (43 arms up, 48 arms down) acquired during hepatic tumor arterial embolization procedures. Read More

    Are We Overtreating Renal Angiomyolipoma: A Review of the Literature and Assessment of Contemporary Management and Follow-Up Strategies.
    Cardiovasc Intervent Radiol 2017 Dec 19. Epub 2017 Dec 19.
    Department of Radiology, Beaumont Hospital, Dublin, Ireland.
    Renal angiomyolipoma (AML) are benign tumours composed of fat, muscle, and disorganised blood vessels. Historic treatment algorithms for sporadic AML based on size fail to consider additional risk factors such as tumour vascularity and pseudoaneurysm formation. As AML is now predominantly incidental, rupture is rare and its mortality low. Read More

    Department of Radiology, Research Institute of Radiology, Asan Medical Center, University of Ulsan College of Medicine, 88, Olympic-ro 43-gil, Songpa-gu, Seoul, 138-736, Republic of Korea.
    Purpose: We aimed to evaluate the frequency and protective factors of acute biliary obstruction in patients with biliary stent placement followed by gastroduodenal covered self-expandable metallic stent (SEMS) placement owing to progression of periampullary cancer.

    Materials And Methods: We retrospectively reviewed 58 patients. Total bilirubin and alkaline phosphatase (ALP) levels before and after gastroduodenal covered SEMS placement were evaluated. Read More

    Clinical Indication for Computed Tomography During Hepatic Arteriography (CTHA) in Addition to Dynamic CT Studies to Identify Hypervascularity of Hepatocellular Carcinoma.

    Diagnostic Radiology, Hiroshima University, 1-2-3 Kasumi, Minami-ku, Hiroshima, Japan.
    Purpose: To identify factors benefiting from computed tomography during hepatic arteriography (CTHA) in addition to dynamic CT studies at the preoperative evaluation of the hypervascularity of hepatocellular carcinoma (HCC).

    Materials And Methods: We retrospectively divided 45 patients with HCC, who underwent both dynamic CT (dCT) and CTHA, into two groups based on the number of hypervascular HCCs identified on dCT and CTHA studies. In group A, the number of HCCs identified by dCT and CTHA was the same and additive CTHA had not been indicated. Read More

    Peripheral Embolization Using Hydrogel-Coated Coils Versus Fibered Coils: Short-Term Results in an Animal Model.
    Cardiovasc Intervent Radiol 2018 Feb 1;41(2):305-312. Epub 2017 Nov 1.
    Normandie University, UNICAEN, CEA, CNRS, ISTCT-CERVOxy, 14000, Caen, France.
    Objectives: To angiographically compare the occlusive effects of hydrocoils and fibered coils in the renal and internal iliac arteries at 24 h and 7 days in the sheep model. To determine the occlusive mechanism by hydrocoils and fibered coils by pathological examination.

    Materials And Methods: Two types of peripheral hydrogel-coated and fibered coils similar in diameter and length were compared. Read More

    Characteristics of a New X-Ray Imaging System for Interventional Procedures: Improved Image Quality and Reduced Radiation Dose.
    Cardiovasc Intervent Radiol 2017 Oct 31. Epub 2017 Oct 31.
    Department of Radiology and Biomedical Imaging, Yale University School of Medicine, 330 Cedar Street, TE 2-230, New Haven, CT, 06520, USA.
    Purpose: To compare image quality and radiation exposure between a new angiographic imaging system and the preceding generation system during uterine artery embolization (UAE).

    Materials And Methods: In this retrospective, IRB-approved two-arm study, 54 patients with symptomatic uterine fibroids were treated with UAE on two different angiographic imaging systems. The new system includes optimized acquisition parameters and real-time image processing algorithms. Read More

    Aortic Bifurcation Morphology Alone is Not Able to Predict Outcome in Patients Submitted to Elective Endovascular Abdominal Aortic Aneurysm Repair.
    Cardiovasc Intervent Radiol 2018 Feb 30;41(2):218-224. Epub 2017 Oct 30.
    Vascular and Endovascular Surgery Division, Department of Surgery "Paride Stefanini", "Sapienza" University of Rome, Policlinico Umberto I, Viale del Policlinico, 155, 00161, Rome, Italy.
    Purpose: The aim of the present study was to evaluate the impact of the aortic bifurcation (AB) morphological characteristics, analyzed on computed tomography angiography (CTA), on outcomes of patients with abdominal aortic aneurysms (AAAs), treated by endovascular aneurysm repair (EVAR) in a single-center experience.

    Materials And Methods: A retrospective analysis was conducted using a prospectively collected database. Morphological features considered as potentially impacting outcomes were maximum AB diameter (ABmax), minimum diameter (ABmin), mean diameter (ABaverage), AB area (ABarea), and AB calcification (ABcalcification) and thrombosis (ABthrombosis).

    Teaching IR to Medical Students: A Call to Action.
    Cardiovasc Intervent Radiol 2018 Feb 30;41(2):203-205. Epub 2017 Oct 30.
    Department of Interventional Radiology, Royal College of Surgeons, Beaumont Hospital, Beaumont Road, Dublin, Ireland.
    Interventional radiology (IR) has grown rapidly over the last 20 years and is now an essential component of modern medicine. Despite IR's increasing penetration and reputation in healthcare systems, IR is poorly taught, if taught at all, in most medical schools. Medical students are the referrers of tomorrow and potential IR recruits and deserve to be taught IR by expert IRs. Read More
