Ultrasonic emulsification and aspiration for coral reef atherosclerosis as a novel alternative to transaortic endarterectomy and thoracic aorta-based bypass grafting.

Transaortic endarterectomy (TE) is an effective and durable method of restoring patency in the aorta afflicted with atherosclerotic disease, which most commonly affects the infrarenal aorta and common iliac artery. When the suprarenal aorta is involved, the disease is usually confined to the orifices of the visceral vessels without obstruction of the aortic lumen. In rare cases, dense, calcified, exophytic, and amorphous lesions causing severe luminal obstruction, termed coral reef atherosclerosis (CRA) of the suprarenal aorta, may occur.

Endovascular Aneurysm Repair-First Strategy for Ruptured Abdominal Aortic Aneurysm Might Not Be Applicable to all Cases.

Background: We evaluate the relationship between the hospital case volume (HCV) and mortality outcomes after open aortic repair (OAR) and endovascular aortic repair (EVAR) of intact (iEVAR) and ruptured (rEVAR) abdominal aortic aneurysm (AAA) using a contemporary administrative database.

Methods: The Healthcare Cost and Utilization Project Database for New York (2016) and New Jersey/Maryland/Florida (2016-2017) were queried using International Classification of Disease-10th edition to identify patients who had undergone OAR and EVAR. The hospitals were categorized into quartiles (Q) per overall (EVAR + OAR) volume, OAR-alone volume and EVAR-alone volume.

Intraoperative Staff Radiation Exposure During Aortic Endovascular Procedures.

Background: The risk of radiation exposure in the surgical operating room (OR) and/or catheterization laboratory is now well established. Complex endovascular procedures often require multiple approaches and different positioning of the staff members around the patient, potentially increasing the levels of radiations exposure. Our goal was to evaluate the levels of radiation exposure of the members of the staff during endovascular aortic procedures in order to propose radioprotection optimization.

Direct oral anticoagulants over warfarin at discharge associated with improved survival and patency in infra-geniculate bypasses with prosthetic conduits.

Objective: There is no consensus on the optimal anticoagulant regimen following lower extremity bypass. Historically, warfarin has been utilized for prosthetic or compromised vein bypasses. Direct-acting oral anticoagulants (DOACs) are increasingly replacing warfarin in this context, but their efficacy in bypass preservation has not been well-studied.

Precocious Rupture of Abdominal Aortic Aneurysms Below Size Criteria for Repair: Risk Factors and Outcomes.

Background: Practice guidelines recommend elective repair for abdominal aortic aneurysms (AAAs) ≥ 5.5 cm in men and ≥ 5 cm in women to prevent rupture; however, some rupture at smaller diameters. We identify risk factors for rupture AAA (rAAA) below this threshold and compare outcomes following rAAA repair above/below size criteria.

Anatomic Utility of Single Branched Thoracic Endograft During Thoracic Endovascular Aortic Repair.

Introduction: Single branched thoracic endografts (SBTEs) have been designed for pathology requiring zone 2 seal during thoracic endovascular aortic repair (TEVAR). Numerous criteria must be met to allow for their implantation. Our aim was to analyze anatomic suitability for a next generation SBTE.

Trends and outcomes associated with intravascular ultrasound use during femoropopliteal revascularization in the Vascular Quality Initiative.

Objective: Intravascular ultrasound (IVUS) use in lower extremity interventions is growing in popularity owing to its imaging in the axial plane, superior detail in imaging lesion characteristics, and its enhanced ability to delineate lesion severity and extent compared with catheter angiograms. However, there are conflicting data regarding whether IVUS affects outcomes. The purpose of this study was to assess the effect associated with IVUS implementation in femoropopliteal interventions.

Outcome after revascularization with paclitaxel-coated devices in patients with chronic limb-threatening ischemia.

Objective: Data regarding the safety and efficacy of paclitaxel (PTX)-coated peripheral arterial devices for femoropopliteal artery (FPA) atherosclerotic disease is derived from studies that mainly evaluated patients with claudication. Outcomes of PTX treatment for patients with chronic limb-threatening ischemia (CLTI) is incompletely defined. This study compares outcome in patients with CLTI treated with and without PTX.

Use of direct-acting oral anticoagulants associated with improved survival and bypass graft patency compared with warfarin after infrageniculate bypass.

Objective: No consensus has yet been reached regarding the optimal antiplatelet and anticoagulant regimen for patients after lower extremity bypass. Usually, patients who have undergone below-the-knee bypass will begin oral anticoagulation therapy. Historically, the bypass has been with prosthetic conduits and the anticoagulation therapy has been warfarin.

Celiac Artery Coverage During TEVAR for Dissection and Acute Aortic Injury is Not Associated with Worse Outcomes.

Background: Studies have previously identified increased morbidity and mortality with celiac artery coverage during thoracic endovascular aortic repair (TEVAR) for aneurysmal disease. This study aimed to delineate the risks associated with celiac artery coverage in all patients undergoing TEVAR for dissection, trauma, or aneurysmal disease.

Methods: Using the Vascular Quality Initiative database, we identified all patients undergoing TEVAR from 2012 to 2020 and categorized them based on the underlying pathology (aneurysm, dissection, or acute/trauma).

Management and Outcome of Non-Aneurysmal Primary Aortic Infection.

Introduction: Aortic infection without prior intervention or aneurysm is exceedingly rare. We report the presentation, diagnosis, management, and outcome of patients with this unusual entity.

Methods: Retrospective chart and imaging review of patients with primary aortic infection.

Impact of interfacility transfer of ruptured abdominal aortic aneurysm patients.

Objective: The interfacility transfer (IT) of patients with a ruptured abdominal aortic aneurysm (rAAA) occurs not infrequently to allow for a higher level of care. In the present study, we evaluated, using a contemporary administrative database, the effects of IT on mortality after rAAA repair.

Methods: The Healthcare Cost and Utilization Project Database for New York (2016) and New Jersey, Maryland, and Florida (2016-2017) was queried using the International Classification of Diseases, 10th edition, to identify patients who had undergone open or endovascular repair of AAAs.

Optimal conduit choice for open lower extremity bypass in chronic limb-threatening ischemia.

Open bypass surgery remains a major tool for limb salvage in chronic limb-threatening ischemia (CLTI). Although rest pain and tissue loss both fall into the category of CLTI, goals of revascularization are markedly different for each context. Rest pain mandates long-term patency considerations.

Physician-modified endografts are associated with a survival benefit over parallel grafting in thoracoabdominal aneurysms.

Objective: Physician-modified endografts (PMEG) and parallel grafting (PG) are important techniques for endovascular repair of complex aortic aneurysms using off-the-shelf devices. However, there are few data regarding the relative efficacy and outcomes of these techniques in thoracoabdominal extent aneurysms. This study sought to compare the outcomes of PG and PMEG across different extents of thoracoabdominal aneurysms (TAAAs) for which they can be used.

Outcomes of great vessel debranching to facilitate thoracic endovascular aortic repair.

Objective: With the expanding application of endovascular technology, the need to deploy into zone 0 has been encountered on occasion. In the present study, we evaluated the outcomes of great vessel debranching (GVD) as a method of extending the proximal landing zone to facilitate thoracic endovascular aortic repair (TEVAR).

Methods: We performed a single-center retrospective review of all patients who had undergone GVD followed by TEVAR between May 2013 and December 2020.

Fenestrated Endovascular Repair With Large Device Diameters (34-36 mm) is Associated With Type 1 and 3 Endoleak and Reintervention.

Background: Patients with abdominal aortic aneurysms undergoing EVAR with larger device diameters (34-36 mm) have worse outcomes due to proximal fixation failure and need for reintervention. We examine outcomes relating to standard fenestrated repair (FEVAR) with larger device diameters, and investigate whether a similar relationship exists.

Methods: Retrospective review of a prospectively maintained, single institution database of patients treated with the Cook ZFEN device between 2012-2017.

Elevated Neutrophil to Lymphocyte Ratio is Associated with Worse Outcomes after Carotid Endarterectomy in Asymptomatic Patients.

Objective: Management of carotid artery stenosis (CAS) remains controversial and proper patient selection critical. Elevated neutrophil to lymphocyte ratio (NLR) has been associated with poor outcomes after vascular procedures. The effect of NLR on outcomes after carotid endarterectomy (CEA) in asymptomatic and symptomatic patients is assessed.

Elevated neutrophil to lymphocyte ratio is associated with decreased amputation-free survival after femoropopliteal percutaneous revascularization.

Background: An elevated neutrophil-lymphocyte ratio (NLR) is a biomarker associated with adverse outcomes after cardiovascular surgery. This study evaluates the association of preoperative NLR with clinical outcomes after peripheral vascular intervention (PVI) of the femoropopliteal segments.

Methods: A retrospective review identified 488 patients who underwent percutaneous interventions of femoropopliteal arteries between 2011 and 2018 and had a pre-procedural complete blood count with differential with normal white blood cell count within 30 days prior to intervention.

Paclitaxel-coated peripheral arterial devices are associated with improved overall survival and limb salvage in patients with chronic limb-threatening ischemia.

Objective: Paclitaxel (PTX)-coated peripheral arterial devices have been shown to decrease femoropopliteal artery restenosis and the need for reintervention compared with non-PTX-coated devices. The data regarding PTX efficacy and safety come from randomized controlled trials that almost exclusively enrolled patients with claudication. The outcomes of PTX treatment in patients who present with chronic limb-threatening ischemia (CLTI) are unknown.

Renal Stent Complications and Impact on Renal Function after Standard Fenestrated Endovascular Aneurysm Repair.

Background: To report renal outcomes including long-term patency, secondary interventions, and related renal function after fenestrated endovascular aortic repair (fEVAR).

Methods: Single-center retrospective review of patients undergoing fEVAR between 2012 and 2018 using the Cook ZFEN device. Renal stent complications, defined as any stenosis, occlusion, kink, renal stent-related endoleak, and reinterventions were tabulated.

Paclitaxel-Coated Peripheral Arterial Devices are Associated with Reduced Mortality in Younger Patients.

Background: Paclitaxel-coated devices have been shown to decrease restenosis when used in the femoropopliteal artery. Recent reports have suggested a possible risk of increased late mortality in patients treated with paclitaxel. It has been suggested that younger patients and those with limited comorbidities may be at higher risk.

Increased vertebral exposure in anterior lumbar interbody fusion associated with venous injury and deep venous thrombosis.

Background: Published outcomes on anterior lumbar interbody fusion (ALIF) have focused on 1-2 level fusion with and without vascular surgery assistance. We examined the influence of multilevel fusion on exposure-related outcomes when performed by vascular surgeons.

Methods: We retrospectively reviewed clinical and radiographic data for patients undergoing anterior lumbar interbody fusion (ALIF) with exposure performed by vascular surgeons at a single practice.
