  • 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.

  • Aortic septotomy to optimize landing zones during thoracic endovascular aortic repair for chronic type B aortic dissection

    Year: 2021

    Affiliation: University of Michigan/University of Virginia

    Citation: The Journal of thoracic and cardiovascular surgery

    Abstract: The role of thoracic endovascular aortic repair for chronic type B aortic dissectionremains controversial. Clinical outcomes of thoracic endovascular aortic repair with recently implemented aortic septotomy strategy were compared with stand-alone thoracic endovascular aortic repair.

  • Mortality After Paclitaxel Coated Balloon Angioplasty and Stenting of Superficial Femoral and Popliteal Artery in the Vascular Quality Initiative

    Year: 2020

    Affiliation: N/A

    Citation: Cardiovascular Interventions

    Abstract: To compare mortality after treatment of superficial femoral-popliteal artery disease with paclitaxel and nonpaclitaxel devices using a multicenter vascular registry.

  • Analysing The Cross-Section of The Abdominal Aortic Aneurysm Neck and Its Effects on Stent Deployment

    Year: 2020

    Affiliation: Scientific Reports

    Citation: European Society for Vascular Surgery

    Abstract: Stent graft devices for the treatment of abdominal aortic aneurysms (AAAs) are being increasingly used worldwide. Yet, during modelling and optimization of these devices, as well as in clinical practice, vascular sections are idealized, possibly compromising the effectiveness of the intervention. In this study, we challenge the commonly used approximation of the circular cross-section of the aorta and identify the implications of this approximation to the mechanical assessment of stent grafts.
