IP031. Factors Affecting Mortality After Aortic Dissection Repair

June 1, 2018 - 00:00
Thirty-day mortality rates after open and endovascular intervention for aortic dissection remain high. Increased understanding of preoperative comorbidities and factors that increase the risk of mortality can help guide patient, family, and provider decision-making.

IP029. Incorporating Patient and Anatomic Factors in Predicting Operative Mortality of Abdominal Aortic Aneurysm Repair: A Robust Risk Score Calculator

June 1, 2018 - 00:00
A recent systematic review examining all available operative mortality risk prediction models after abdominal aortic aneurysm (AAA) repair identified the shortcomings of the current risk calculators. Those were the sole reliance on the physiologic condition of the patient and lack of aneurysm-related predictors. For example, the Medicare model was derived from a 2001 to 2004 population in the early emergence of endovascular aneurysm repair (EVAR) and did not account for any anatomic, laboratory, or medication factors.

IP027. Impact of Patient Factors and Procedure on Readmission After Aortic Dissection Admission

June 1, 2018 - 00:00
Aortic dissection (AD) admissions carry significant morbidity and mortality. However, readmissions after AD admission are not well described. We sought to define readmission rates after AD and to identify factors associated with them.

IP025. Anatomic Feasibility of Branched-Fenestrated Stent Grafts to Treat Arch Aneurysms in the Japanese Population∗

June 1, 2018 - 00:00
The objective of this study was to analyze the anatomic characteristics of arch aneurysms in the Japanese population and to evaluate the feasibility of four next-generation stent grafts with branched or fenestrated configuration.

IP023. Type II Endoleak Incidence and Fate After Endovascular Aneurysm Repair by Low-Profile Polymer-Based Endograft Implantation in an Unselected Population∗

June 1, 2018 - 00:00
A potential correlation between the indication for low-profile endograft implantation and the incidence of type II endoleaks (T2ELs) after endovascular aneurysm repair (EVAR) of abdominal aortic aneurysms has been postulated. The aim of this study was to report the immediate and midterm incidence and fate of T2ELs in an unselected population of patients treated by EVAR using the Ovation stent graft (Endologix, Irvine, Calif).

IP021. Reintervention After Thoracic Endovascular Aortic Repair by Aortic Disease and the Impact on Patient Survival

June 1, 2018 - 00:00
Using a national data set, we sought to describe the population of patients for and the nature and timing of reinterventions after thoracic endovascular aortic repair (TEVAR) by aortic disease as well as by the impact on survival.

IP019. Population-Based Assessment of Aorta-Related Outcomes in Acute Aortic Syndrome

June 1, 2018 - 00:00
The impact of acute aortic syndrome (AAS) on mortality and aorta-related events has not been examined from a population-based approach. This study analyzes aorta-related outcomes in a newly diagnosed cohort of AAS patients.

IP017. Performance of Current Claims-Based Approaches to Identify Aortic Dissection Hospitalizations

June 1, 2018 - 00:00
Methods that use claims data to identify patients with aortic dissection (AD) for study are not well validated. We aimed to evaluate the accuracy of previously reported diagnosis and procedural coding mechanisms to identify AD admissions and treatment types for patients with acute AD at our institution.

IP015. Patients With End-Stage Renal Disease Have Poor Outcomes After Endovascular Abdominal Aortic Aneurysm Repair

June 1, 2018 - 00:00
Although endovascular aneurysm repair (EVAR) of abdominal aortic aneurysms (AAA) has been demonstrated to have favorable outcomes, not all cohorts of patients with AAA fare equally well. Our goal was to investigate perioperative and 1-year outcomes in patients with end-stage renal disease (ESRD) on dialysis, who have traditionally fared worse after vascular interventions, to assess how ESRD affects outcomes in a large modern cohort of EVAR patients.

IP013. The Weekend Effect in Abdominal Aortic Aneurysm Repair

June 1, 2018 - 00:00
Conflicting reports exist about whether patients undergoing surgery on the weekend or later in the week experience worse outcomes.

IP011. Factors Associated With Postoperative Renal Dysfunction and the Subsequent Impact on Survival After Open Juxtarenal Abdominal Aortic Aneurysm Repair

June 1, 2018 - 00:00
Renal dysfunction is a well-described complication of open juxtarenal abdominal aortic aneurysm repair; however, the associated risk factors and corresponding impact on survival are not well described.

IP009. Intraoperative Contrast-Enhanced Ultrasound for Early Diagnosis and Treatment of Endoleaks During Endovascular Abdominal Aortic Aneurysm Repair∗

June 1, 2018 - 00:00
The objective of this study was to evaluate the feasibility of intraoperative contrast-enhanced ultrasound (CEUS) to detect and to treat endoleaks (EL) during endovascular aneurysm repair (EVAR).

IP007. Feasibility of Endovascular Abdominal Aortic Aneurysm Repair Procedure Supported by Very-Low-Dose Stationary Acquisition Protocols∗

June 1, 2018 - 00:00
The objective of this study was to evaluate the feasibility of very-low-dose stationary acquisition protocols (SAPs) during an endovascular aneurysm repair (EVAR) procedure and to perform a dosimetric evaluation of the radiation exposure to the patients.

IP005. Preoperative Aneurysmal Thrombus Volume and Patency of Aortic Branch Vessels Are Inversely Correlated in Abdominal Aortic Aneurysm

June 1, 2018 - 00:00
Some evidence suggests that preoperative aneurysmal thrombus volume and the number and diameter of patent infrarenal aortic branch vessels affect the incidence of type II endoleak after endovascular aneurysm repair of infrarenal abdominal aortic aneurysm. The objective of this study was to investigate whether the patency of infrarenal aortic branch vessels is related to aneurysmal thrombus volume.

IP003. Aortic Dissection-Related Mortality in Washington State Remains Unchanged From 1996 to 2016

June 1, 2018 - 00:00
Long-term outcomes for patients with aortic dissection (AD) are difficult to assess because of incomplete follow-up, and mortality reporting for dissection is sparse. From 1996 to 2016, there was a significant decline in aortic aneurysm-related mortality rates in Washington state. The aim of this study was to evaluate AD related mortality in Washington state from 1996 to 2016 with the hypothesis that a similar decline in mortality would be observed.

SS11. Clinical Impact of a Wound Care Center on a Vascular Surgery Practice

June 1, 2018 - 00:00
Wound centers provide an opportunity for specialty services to deliver aggressive wound care before and after revascularizations or hospitalizations and must work closely with vascular surgeons. Such a program would therefore be expected to have a significant impact on the affiliate vascular surgical practice. The purpose of this study was to evaluate the impact of a new wound care center’s opening on the practice patterns of a tertiary care vascular surgery service.

SS10. Financial Impact of Implementing Care Delivery Redesign Initiatives for Vascular Surgery in a Hospital Setting

June 1, 2018 - 00:00
A fragmented health care system contributes to suboptimal resource utilization and care coordination. A Care Delivery Redesign (CDR) for the vascular surgery service was developed to improve diagnosis-related group (DRG) assignment, to decrease length of stay (LOS), and to minimize care variation through standardized care pathways. We measured the value of CDR through hospital financial metrics.

SS08. Exercise Transcutaneous Oxygen Pressure Measurement Is a Reliable Method of Evaluation of Internal Iliac Artery Flow Compromise

June 1, 2018 - 00:00
Clinical differentiation of buttock claudication from pseudoclaudication (neuromuscular etiology) is often challenging, and it cannot be diagnosed noninvasively using standard ankle-brachial index with exercise. The aim of this study was to evaluate the reliability of exercise transcutaneous oximetry (ExTcPo2) to accurately detect significant internal iliac artery (IIA) inflow stenosis.

SS07. Association of Opioid Abuse and Peripheral Arterial Disease

June 1, 2018 - 00:00
Prescription opioids account for 40% of all U.S. opioid overdose deaths, and national efforts have intensified to reduce opioid prescriptions. However, little is known about the relationship between peripheral arterial disease (PAD) and high-risk opioid use. The objectives of this study were to evaluate the relationship between PAD and high opioid use and to assess whether PAD treatment has an impact on high opioid use.

RS03. Tapered Arteriovenous Grafts Do Not Provide Significant Advantage Over Nontapered Grafts in Upper Extremity Dialysis Access

June 1, 2018 - 00:00
Although tapered dialysis access grafts are often used in an effort to prevent ischemic steal, their efficacy is uncertain. Our goal was to use real-world data to assess the performance of these grafts with respect to steal and primary patency.
