Management and Treatment of Tandem Carotid Lesions.

Background: Tandem lesions of the proximal aortic branch vessels and carotid bifurcation are uncommon. While management strategies vary, a hybrid approach of carotid endarterectomy with retrograde common carotid artery (CCA) or innominate artery (IA) stenting has become a mainstay of treatment. The purpose of this article was to provide a review of the literature, discuss alternative treatment modalities, and highlight technical considerations of the hybrid approach.

Appropriate Use Criteria Committees: The professional society role in the development and implementation of Appropriate Use Criteria.

Vascular surgeons have the ability to manage and intervene on numerous vascular diseases of both the arterial and venous systems. With the growing number of interventions available as endovascular technology evolves, it is important to determine when a procedure is safely indicated for a vascular surgery patient. Appropriate Use Criteria (AUC) offer synthesized clinical information and practice standards that can aid clinicians in making these management decisions.

Effects of abdominal aortic aneurysm appropriateness dashboard on clinical practice.

Objective: The Society for Vascular Surgery published abdominal aortic aneurysm (AAA) practice guidelines in 2003, 2009, and 2018 to improve the management and treatment of AAAs. In 2014, our vascular surgery department implemented a quarterly AAA dashboard (AAAdb) to record the perioperative outcomes and guideline compliance with a focus on intervention appropriateness and procedural follow-up, which supplemented our Vascular Quality Initiative data. From the available reported evidence and expert consensus opinions, nine additional criteria for the appropriate treatment of AAAs <5 cm in women and <5.

Value of Routine Troponin Measurement in Open Abdominal Aortic Aneurysm Repair.

Background: Cardiovascular complications are a major cause of morbidity and mortality in the postoperative period after major vascular surgery. Depending on the study population, up to 25% of patients have troponin elevation after noncardiac surgery, yet many do not meet the diagnosis of myocardial infarction (MI). Although outcomes of routine troponin elevation in patients undergoing mixed major vascular surgery have been evaluated, this has not been studied exclusively in elective, open abdominal aortic aneurysm repair (oAAA), especially regarding perioperative and overall mortality.

Hypogastric artery luminal diameter predicts common-external iliac stent patency and major adverse limb events in patients with aortoiliac occlusive disease.

Objective: Hypogastric coverage may be required for occlusive disease at the iliac arterial bifurcation. In this study, we sought to determine patency rates of common-external iliac artery (C-EIA) bare metal stents (BMS) spanning the hypogastric origin in patients with aortoiliac occlusive disease (AIOD). In addition, we sought to identify predictors of C-EIA BMS patency loss and major adverse limb events (MALE) in patients requiring hypogastric coverage.

A Novel Technique and Outcomes for Transcaval Endoleak Embolization.

Background: Strategies for embolization of type 2 endoleaks include translumbar, transgraft, transarterial, and transcaval approaches. The transcaval approach is limited by an inconsistent ability to access the aortic sac and the risk of puncturing and damaging the endograft or adjacent structures. We describe a novel technique for caval to aortic aneurysm sac access and report early outcomes.

Ultra-Hybrid Repair: Open Thoracoabdominal Completion After Descending Stent Grafting.

To characterize patient risk profiles and outcomes associated with staged ultra-hybrid repair of extensive aortic disease, in which open thoracoabdominal completion was performed after thoracic stent grafting. From 1/2006 to 1/2021, 92 patients underwent open thoracoabdominal repair of chronic dissection (n=58, 63%), degenerative aneurysm (n=28, 30%), endoleak (n=4, 4.3%), or symptomatic acute type B dissection (n=2, 2.

Early results of bare metal extension stent for thoracoabdominal aortic dissection.

Objectives: Debakey type I and IIIb aortic dissections are complicated by extension along the full length of the aorta. Over the long term, the thoracoabdominal aorta in these patients often continues to degenerate, requiring endovascular or open repair. The purpose of this investigation is to determine the early clinical outcome on aortic remodeling using a composite thoracic stent graft and thoracoabdominal bare metal extension stenting strategy.

Outcomes of Gore iliac branch endoprosthesis with internal iliac component versus Gore Viabahn VBX.

Objective: The Gore Excluder iliac branch endoprosthesis (IBE; W.L. Gore & Associates, Flagstaff, AZ) is the only iliac branch device approved in the United States to preserve blood flow to the external and internal iliac arteries (IIAs).

One-year results with a low-profile endograft in subjects with thoracic aortic aneurysm and ulcer pathologies.

Objective: The study objective was to evaluate the safety and effectiveness of the second-generation, low-profile RelayPro (Terumo Aortic) thoracic endograft for the treatment of descending thoracic aortic aneurysm or penetrating atherosclerotic ulcer.

Method: A prospective, international, nonblinded, nonrandomized, pivotal trial analyzed a primary safety end point of major adverse events at 30 days (death, myocardial infarction, stroke, renal/respiratory failure, paralysis, bowel ischemia, procedural blood loss) and a primary effectiveness end point of treatment success at 1 year (technical success, patency, absence of aneurysm rupture, type I/III endoleaks, stent fractures, reinterventions, aneurysm expansion, and migration) compared with performance goals from the previous generation Relay pivotal study. The study was conducted in 36 centers in the United States and Japan and enrolled participants between 2017 and 2019.

Natural history and growth rates of isolated common iliac artery aneurysms.

Objective: The natural history of isolated common iliac artery aneurysms (CIAAs) has not been well-studied. The optimal size threshold for elective repair of isolated CIAAs is also not well-defined. We sought to determine the natural history and growth rates of isolated CIAAs to justify a surveillance protocol and size for elective repair.

Racial disparities in presentation and short-term outcomes for patients with acute type B aortic dissection.

Objective: Racial disparities in cardiovascular risk factors and disease outcomes have been well documented. A knowledge gap exists regarding the role that health maintenance plays in the development and outcomes of type B aortic dissection (TBAD). In the present study, we evaluated the comparative presentation and short-term outcomes of patients with TBAD across race.

Optimal Timing of Surveillance Ultrasounds in Small Aortic Aneurysms.

Background: Small abdominal aortic aneurysms (AAA) surveillance intervals remain controversial and difficult to standardize. Current Society for Vascular Surgery guidelines lack quality evidence. The objective of this study is to examine patients followed in a high volume non-invasive vascular laboratory, determine if the current guidelines are fitting in clinical practice, and attempt to further identify risk factors for accelerated aneurysm growth.

Comparison of Aortobifemoral Bypass to Aortoiliac Stenting with Bifurcation Reconstruction for TASC II D Aortoiliac Occlusive Disease.

Background: Long-segment stenting of the infrarenal aorta and bilateral iliac arteries, with or without femoral endarterectomy for diffuse disease, has been adopted for treatment of severe aortoiliac occlusive disease (AIOD). The objective of this study was to compare outcomes of this reconstruction, termed aortoiliac stenting with bifurcation reconstruction (AISBR), to aortobifemoral bypass (ABF) in patients with comparable TASC II D lesions.

Methods: This is a single-center, retrospective review of patients treated with ABF or AISBR for comparable TASC II D lesions between 2010 and 2018.

Standardizing Methods of Reading CT Maximum Aortic Diameters Amongst Experts Reduces Variations and Discordance, Improving Accuracy.

Background: There is no consensus on the method of obtaining abdominal aortic aneurysm (AAA) maximum diameters based on computed tomographic angiography, and the reproducibility and accuracy of different methods have recently been debated due to advancements in imaging. This study compared the two most common methods based on orthogonal planes and centerline of flow to determine the discordances and accuracy amongst experiences readers.

Methods: The computed tomographic angiography max diameters of 148 AAAs were measured by three experienced observers, including a vascular surgeon, a radiologist and an imaging cardiologist.

Outcomes and role of peripheral revascularization in type A aortic dissection presenting with acute lower extremity ischemia.

Objective: Limited data exists on management and outcomes of patients presenting with type A aortic dissection (TAAD) and acute lower extremity ischemia (ALI). The role of limb-related revascularization and optimal treatment strategy remains undefined. The objective of this study was to analyze dissection characteristics, treatment modalities, and outcomes of patients undergoing proximal aortic repair for TAAD with ALI.

Outcomes of Hypogastric Coverage and Occlusion during Endovascular Treatment of Aortoiliac Occlusive Disease.

Background: The risk of hypogastric occlusion (HO) following bare-metal stent (BMS) coverage of the hypogastric origin during endovascular treatment of aortoiliac occlusive disease (AIOD) is unclear. This study sought to determine the rate and clinical significance of HO following BMS coverage during iliac stenting for complex AIOD.

Methods: Consecutive patients undergoing elective iliac stenting for AIOD from 2010-2018 at Cleveland Clinic were reviewed.

Health-Related Quality of Life After Extensive Aortic Replacement.

To assess and compare patient-reported long-term health-related quality of life (HRQoL) after combined proximal aortic (arch ± ascending, root) and distal aortic (descending thoracic ± abdominal) replacement using open vs multimodal/endovascular (hybrid) approaches. From 2010 to 2016, 146 adults underwent single- or multi-stage aortic arch plus descending thoracic aorta replacement, 31 open and 115 hybrid. The 2 surgical approach groups had similar preoperative characteristics and extent of surgery.

Improving clinical documentation of evaluation and management care and patient acuity improves reimbursement as well as quality metrics.

Objective: Accurate documentation of patient care and acuity is essential to determine appropriate reimbursement as well as accuracy of key publicly reported quality metrics. We sought to investigate the impact of standardized note templates by inpatient advanced practice providers (APPs) on evaluation and management (E/M) charge capture, including outside of the global surgical package (GSP), and quality metrics including case mix index (CMI) and mortality index (MI). We hypothesized this clinical documentation initiative as well as improved coding of E/M services would result in increased reimbursement and quality metrics.

Visceral segment aortic thrombus is associated with proximal aortic degeneration after infrarenal abdominal aortic aneurysm repair.

Objective: To identify predictors of aortic aneurysm formation at or above an infrarenal abdominal aortic aneurysm repair.

Methods: A total of 881 infrarenal abdominal aortic aneurysm repairs were identified at a single institution from 2004 to 2008; 187 of the repairs were identified that had pre-operative and post-operative computed tomography imaging at least one year or greater to evaluate for aortic degeneration following repair. Aortic diameters at the celiac, superior mesenteric, and renal arteries were measured on all available computed tomographic scans.
