  • Predicting Distal Aortic Remodeling After Endovascular Repair for Chronic DeBakey III Aortic Dissection

    Year: 2018

    Affiliation: University of Pennsylvania/ University of Pittsburgh

    Citation: The Annals of Thoracic Surgery

    Abstract: Chronic DeBakey III aortic dissection is typically managed with open aortic reconstruction. Thoracic endovascular aortic grafting (TEVAR) has been attempted in patients with chronic DeBakey III with improved outcomes over medical management, however with frequent failures. This study investigates factors associated with positive aortic remodeling from a large aortic center.

  • Neck diameter and inner curve seal zone predict endograft-related complications in highly angulated necks after endovascular aneurysm repair using the Aorfix endograft

    Year: 2018

    Affiliation: Elsevier User License

    Abstract: Many studies have found that preoperative aneurysm anatomy can determine the postoperative complication rates for endovascular aneurysm repair (EVAR). With continual improvement in endograft technology, patients with challenging anatomy are increasingly able to undergo successful treatment with EVAR. This study aimed to quantify the influence of proximal neck anatomy on contemporary outcomes in a cohort of abdominal aortic aneurysm patients with highly angulated aneurysm necks.

  • A case-matched validation study of anatomic severity grade score in predicting reinterventions after endovascular aortic aneurysm repair

    Year: 2013

    Affiliation: Eastern Virginia Medical School

    Citation: Journal of Vascular Surgery

    Abstract: In 2002, the Society for Vascular Surgery created the anatomic severity grading (ASG) score to classify abdominal aortic aneurysms (AAAs). Our objective was to identify the predictive capability and cutoff value of preoperative ASG score for reintervention after endovascular aneurysm repair (EVAR).

  • Anatomic severity grading score predicts technical difficulty, early outcomes, and hospital resource utilization of endovascular aortic aneurysm repair

    Year: 2011

    Affiliation: Society for Vascular Surgery

    Citation: New England Journal of Medicine

    Abstract: In 2002, a system for the grading of abdominal aortic aneurysms (AAAs) was developed by the Society for Vascular Surgery (SVS). Because the correlation of the anatomic severity grading (ASG) score to patient outcomes has yet to be validated, we provide our experience with calculating the ASG score using three-dimensional (3-D) image-rendering software and provide the practical translation of this score into early outcomes and hospital charges

  • Preoperative Relative Abdominal Aortic Aneurysm Thrombus Burden Predicts Endoleak and Sac Enlargement After Endovascular Anerysm Repair

    Year: 2011

    Affiliation: New York University Langone Medical Center

    Citation: Peripheral Vascular Society

    Abstract: Endoleak and sac growth remain unpredictable occurrences after EVAR, necessitating regular surveillance imaging, including CT angiography. This study was designed to identify preoperative CT variables that predict AAA remodeling and sac behavior post-EVAR.

  • Simulation Case Rehearsals for Carotid Artery Stenting

    Year: 2009

    Affiliation: U of Rochester Medical Center

    Citation: European Journal of Vascular and Endovascular Surgery

    Abstract: A case series of 5 patients is presented assessing the utility of simulation case rehearsals of individual patients for carotid artery stenting on an endovascular simulator. Simulated and operative device dimensions were similar. Results of subjective surveys indicated that face and content validity were excellent. The simulations predicted difficulty with vessel cannulation, however had difficulty predicting post-stent changes in bifurcation angulation. Our experience suggests that it may be feasible to use patient-specific CTA-derived data in the creation of a realistic case rehearsal simulation. The overall utility of this concept, including cost-benefit analysis, has yet to be determined.

  • Identifying the Appropriate Thoracic Device Size

    Year: 2017

    Affiliation: NYU Langone Health

    Citation: Endovascular Today

    Abstract: "Endovascular aortic stent grafts have forever altered the techniques and strategies for manag- ing the pathology of the aorta. Although many cases still require open repair, large studies dem- onstrate that there has been a tremendous increase in the percentage of thoracic endovascular aneurysm repairs (TEVARs) of all descending thoracic aorta surgeries performed in the United States since 2005.1"

  • The Role of Color Duplex Ultrasound in Patients with Abdominal Aortic Aneurysms and Peripheral Aneurysms

    Year: 2017

    Affiliation: U of Tennesee / U of Cincinnati

    Citation: Noninvasive Vascular Diagnosis

    Abstract: Ultrasound diagnosis has been used for abdominal aortic aneurysms and peripheral aneurysms for many years, yet the nuances required for proper interrogation and interpretation can be quite difficult. While CT and ultrasound have been used interchangeably, it is become clear that the measurements derived are not necessarily equivalent. Newer ultrasound technology allows CT and ultrasound images to be fused for correlation of differences between these modalities. This fusion technology may allow differences between the imaging techniques to be resolved during the real-time ultrasound evaluation.

  • A pilot study for long-term outcome assessment after aortic aneurysm repair using Vascular Quality Initiative data matched to Medicare claims

    Year: 2017

    Affiliation: Dartmouth / Northwestern University / U of Utah / U of Florida / Cornell

    Citation: Journal of Vascular Surgery

    Abstract: Accurate and complete long-term postoperative outcome data are critical to improving value in health care delivery. The Society for Vascular Surgery Vascular Quality Initiative (VQI) is an important tool to achieve this goal in vascular surgery. To improve on the capture of long-term outcomes after vascular surgery procedures for patients in the VQI, we sought to match VQI data to Medicare claims for comprehensive capture of major clinical outcomes in the first several years after vascular procedures.
