    Role of molecular imaging with positron emission tomographic in aortic aneurysms.
    J Thorac Dis 2017 Apr;9(Suppl 4):S333-S342
    Department of Cardiology, Weill Cornell Medicine, New York, USA.
    Aortic aneurysms (AA) are often asymptomatic before the occurrence of acute, potentially fatal complications including dissection and/or rupture. Beyond aortic size, the ability to assess aortic wall characteristics and processes contributing to aneurysm development may allow improved selection of patients who may benefit from prophylactic surgical intervention. Current risk stratification for aneurysms relies upon routine noninvasive imaging of aortic size without assessing the underlying pathophysiologic processes, including features such as inflammation, which may be associated with aneurysm development and progression.

    Imaging for surveillance and operative management for endovascular aortic aneurysm repairs.
    J Thorac Dis 2017 Apr;9(Suppl 4):S309-S316
    Division of Cardiology, Department of Medicine, Weill Cornell Medical College, New York, NY, USA.
    Endovascular aortic aneurysm repairs rely heavily on radiologic imaging modalities for preoperative surveillance, intraoperative management, and postoperative follow-up. Ultrasonography, computed tomography (CT), magnetic resonance imaging (MRI) and angiography all have utility at different stages of management. Often one imaging modality compliments another by providing supplementary information. Read More

    Contrast-Enhanced Ultrasound in the Follow-Up of Endoleaks after Endovascular Aortic Repair (EVAR).
    Ultraschall Med 2017 May 16. Epub 2017 May 16.
    Department of Clinical Radiology, Ludwig-Maximilians-University of Munich-Großhadern Campus, Munich, Germany.
    Endovascular aortic repair (EVAR) has become established in the treatment of abdominal aortic aneurysms and shows potential benefits such as a low perioperative morbidity and a short hospitalization duration. The follow-up after EVAR primarily consists of lifelong postinterventional imaging of the aneurysm size in order to detect complications such as endoleaks or stent dislocation. Computed tomography angiography, an imaging modality that uses ionizing radiation and that relies on a contrast medium which is dependent on thyroid and renal function, is widely used for follow-up.

    The Consequences of Real Life Practice of Early Abdominal Aortic Aneurysm Repair: A Cost-Benefit Analysis.
    Eur J Vasc Endovasc Surg 2017 May 12. Epub 2017 May 12.
    Department of Surgery, Einthoven Laboratory for Experimental Vascular Medicine, Leiden University Medical Centre, Leiden, The Netherlands. Electronic address:
    Background: The reported 54 mm median intervention diameter for endovascular aneurysm repair (EVAR) in the Vascular Quality Initiative and European data from the Pharmaceutical Aneurysm Stabilisation Trial (PHAST) implies that in real life the majority of abdominal aortic aneurysm (AAA) repairs occur at diameters smaller than the consensus intervention threshold of 55 mm. This study explores the potential consequences of this practice.

    Methods: The differences between real life AAA repair and consensus based intervention threshold were explored in reported data from vascular quality initiatives and PHAST. Read More

    Metformin treatment does not affect the risk of ruptured abdominal aortic aneurysms.
    J Vasc Surg 2017 May 12. Epub 2017 May 12.
    Elitary Research Centre of Individualized Medicine in Arterial Disease (CIMA), Odense University Hospital, Odense, Denmark; Department of Vascular Surgery, Odense University Hospital, Odense, Denmark.
    Objective: Diabetes counteracts formation and rupture of abdominal aortic aneurysms, possibly through arterial matrix accumulation. Use of metformin, on the other hand, reduces arterial accumulation of matrix molecules. Consequently, we hypothesized that metformin treatment may reverse the protective role of diabetes on the development and course of aneurysms, that is, that metformin would be associated with aneurysm rupture among individuals with diabetes.

    Bifurcated-bifurcated aneurysm repair is a novel technique to repair infrarenal aortic aneurysms in the setting of iliac aneurysms.
    J Vasc Surg 2017 May 11. Epub 2017 May 11.
    Department of Surgery, University of Washington, Seattle, Wash.
    Background: Up to 40% of abdominal aortic aneurysms (AAAs) have coexistent iliac artery aneurysms (IAAs). In the past, successful endovascular repair required internal iliac artery (IIA) embolization, which can lead to pelvic or buttock ischemia. This study describes a technique that uses a readily available solution with a minimally altered off-the-shelf bifurcated graft in the IAA to maintain IIA perfusion. Read More

    Eur J Vasc Endovasc Surg 2017 May 7. Epub 2017 May 7.
    Vascular Surgery Unit, S. Maria della Misericordia Hospital, University of Perugia, Perugia, Italy.
    Objective/background: Absence of an adequate iliac seal rarely represents an absolute contraindication to endovascular abdominal aortic aneurysm repair. Iliac branch devices (IBD) are increasingly used in patients with extensive aorto-iliac aneurysmal disease, but few data are available on the long-term results of these procedures.

    Methods: Between 2006 and 2016, 157 consecutive IBD procedures performed at a single centre were entered into a prospective database. Read More

    A robust construction algorithm of the centerline skeleton for complex aortic vascular structure using computational fluid dynamics.
    Comput Biol Med 2017 Apr 29;86:6-17. Epub 2017 Apr 29.
    Center for Computational Surgery, Houston Methodist Hospital, 6670 Bertner Avenue, WP254, Houston, TX 77030, USA; LaSIE UMR - 7356 CNRS - University of La Rochelle, Avenue Michel Crépeau, 17042, La Rochelle Cedex 1, France.
    Centerlines of blood vessels are useful tools to make important anatomical measurements (length, diameter, area), which cannot be accurately obtained using 2D images. In this paper a brand new method for centerline extraction of vascular trees is presented. By using computational fluid dynamics (CFD) we are able to obtain a robust and purely functional centerline allowing us to support better measurements than classic purely geometrical-based centerlines.

    Lasarettet Kalmar - Kirurgiska kliniken Kalmar, Sweden - Linköping, Sweden.
    Endovascular or open surgery for elective abdominal aortic surgery? Evidence from the 5 randomized trials OAR (open aortic repair) can be demanding for fragile patients, but has good long-term durability. EVAR (endovascular aortic repair) is more lenient, but is associated with life-long controls, more life-threatening reinterventions, a remaining threat of rupture and a possibly increased risk of death by cancer. All patients with an AAA (abdominal aortic aneurysm) must recieve a thorough evaluation of medical risk and expected survival before open/endovascular treatment and a discussion of the short- and long-term risks of the different treatment alternatives.

    Objective: Patients undergoing open abdominal aortic aneurysm (AAA) repair are at risk of perioperative infections that can lead to subsequent complications. Our goal was to understand how an initial infectious complication influences the risk of subsequent complications in this cohort of patients.

    Methods: Using the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database (2005 to 2012), we evaluated the relationship between three index infectious complications after open elective AAA repair (pneumonia, deep/organ surgical site infection, and urinary tract infection) and subsequent complications.

    A Steerable Sheath to Deploy Hypogastric Bridging Stent by Contralateral Femoral Approach in an Iliac Branch Procedure after EVAR.

    Department of Surgery "PietroValdoni", "Sapienza" University, Rome.
    Aneurysmal degeneration of distal landing zones after endovascular aneurysm repair (EVAR), can be a potential cause of late failure of this technique. Aneurysmal degeneration of common iliac arteries increases the risk of rupture of the iliac aneurysm itself as well as of the abdominal aortic aneurysm (AAA) owing to aneurysm's reperfusion as a type Ib endoleak. Reoperation consists in plugging and covering the internal iliac artery (IIA), by extension into the external iliac artery, or preservation of antegrade flow in IIA by iliac branch devices (IBD) or sandwich technique.

    Complicated infective endocarditis: a case series.
    J Med Case Rep 2017 May 8;11(1):128. Epub 2017 May 8.
    Division of Cardiothoracic Surgery, Kangnam Sacred Heart Hospital, Hallym University Medical Center, Seoul, South Korea.
    Background: Infective endocarditis is associated with not only cardiac complications but also neurologic, renal, musculoskeletal, and systemic complications related to the infection, such as embolization, metastatic infection, and mycotic aneurysm.

    Case Presentation: We report three cases (the first patient is Chinese and the other two are Koreans) of complicated infective endocarditis; two of the cases were associated with a mycotic aneurysm, and one case was associated with a splenic abscess. One case of a patient with prosthetic valve endocarditis was complicated by intracerebral hemorrhage caused by mycotic aneurysm rupture. Read More

    Leaking abdominal aortic aneurysm mimicking ureteric colic: So rare but so real in Middle East.
    Urol Ann 2017 Apr-Jun;9(2):192-193
    Department of Urology, King Hamad University Hospital, Al Sayh, Kingdom of Bahrain.
    Aortic aneurysms are very rare in Middle East unlike Europe and America. Therefore, this pathology is very likely to be missed in acute presentation to the Emergency Medicine Department. We present a case of leaking abdominal aortic aneurysm mimicking right ureteric colic, which was missed in the initial assessment. Read More

    Third vs. Second Generation Stent-Graft for Endovascular Aneurysm Repair: a device specific analysis.

    Embo-EVAR: a technique to prevent type II endoleak? A single centre experience.
    Ann Vasc Surg 2017 May 4. Epub 2017 May 4.
    Vascular Surgery Department. - U. Parini Hospital - 11100 AOSTA - ITALY.
    Objectives: To evaluate the role of intraprocedural aneurysm sac embolisation (embo-EVAR) during endovascular abdominal aneurysm repair (EVAR) using coils and fibrin glue for preventing type II endoleak (EII).

    Materials And Methods: A retrospective clinical case analysis of 72 patients who underwent EVAR during the period 2011-2014. Two groups were compared at 6 and 12 months follow-up with MDCT scan and Contrast-enhanced ultrasound (CEUS) imaging: consecutively, 36 patients (group A) treated with classic EVAR and 36 patients (group B) treated with embo-EVAR.
