Current Status of Endovascular Preservation of the Internal Iliac Artery with Iliac Branch Devices (IBD).

Cardiovasc Intervent Radiol 2019 Mar 11. Epub 2019 Mar 11.

Division of Vascular and Endovascular Surgery, Department of Cardiac, Thoracic and Vascular Sciences, University of Padova, Padova, Italy.

Endovascular aneurysm repair (EVAR) has become the most utilized treatment for abdominal aortic aneurysms (AAA), but the presence of common iliac dilatation or aneurysm may prevent the achievement of effective distal seal and fixation. Ideal repair in these cases should involve both effective preservation of the pelvic circulation and durable exclusion of the AAA. Unilateral or bilateral internal iliac artery (IIA) preservation with iliac branch devices (IBD) is safe, feasible and effective with technical and clinical outcomes comparable to standard EVAR.

Fusion Imaging and Virtual Navigation to Guide Percutaneous Thermal Ablation of Hepatocellular Carcinoma: A Review of the Literature.

Cardiovasc Intervent Radiol 2019 May 26;42(5):639-647. Epub 2019 Feb 26.

Department of Surgical Sciences, Radiology Institute, Città della Salute e della Scienza, Torino, University of Torino, Turin, Italy.

As medical imaging advancements have improved the detectability of hepatocellular carcinoma (HCC) in early stages, the approach to percutaneous thermal ablation for curative treatment has concomitantly advanced. Although many centers are adopting cross-sectional imaging to guide percutaneous ablation, the majority of procedures are still performed under ultrasound (US) guidance worldwide. Challenges to ultrasound guidance may present due to relatively poor resolution particularly with small or isoechoic lesions, or due to intervening structures such as the bowel or diaphragm that obstruct lesional visualization.

Two Wire System and Modified Olive Tip to Facilitate Implantation of Fenestrated TEVAR in Patient with Proximal Descending Aortic Pathology: First Two Cases.

Cardiovasc Intervent Radiol 2019 May 14;42(5):763-769. Epub 2019 Feb 14.

Department of Radiology, John Redcliffe Hospital, Oxford, OX3 9DU, UK.

Introduction: Although Fenestrated TEVAR (F-TEVAR) has been considered to be a more physiologic approach to treat proximal descending aortic pathology, its application is still limited due to availability, cost and technical difficulties. We introduce a new design of fenestrated stent graft with a new delivery system and successfully performed first in human implantation in two patients, one with an aortic aneurysm and one with an acute aortic dissection.

Materials And Methods: The design of these two wires fenestrated stent graft include creation of an additional lumen at the side of the olive tip during manufacture, from which an additional wire can be introduced for a side branch passing into the fenestration, running inside the stent graft and exit the delivery sheath through additional hub.
