HDA 2. Use of Covered Stents in Central Vein Stenosis After Vascular Accesses

31 October 2018 - 11:00pm
Percutaneous transluminal angioplasty (PTA) in central vein stenosis represents the first therapeutic option, although high rates of restenosis are present. The aim of the study was to present our experience in using nitinol-polytetrafluoroethylene covered stents in the treatment of central vein stenosis.

31 October 2018 - 11:00pm
The aim of this prospectively collected case series was to demonstrate a novel technique of using the ClariVein (Vascular Insights, Quincy, Mass) catheter for pharmacomechanical thrombolysis of thrombosed hemodialysis grafts.

CAD 6. Clinical Results and Experimental Data of a MicroNet-Covered Carotid Stent (CGuard)

31 October 2018 - 11:00pm
This was an assessment of the clinical implantation procedure and in vitro investigation of the mechanical properties of the novel MicroNet-covered stent for the carotid artery.

CAD 5. Risk Factors for Stroke After Carotid Surgical Interventions

31 October 2018 - 11:00pm
We aimed to assess stroke rates after carotid revascularization surgery and to identify factors influencing stroke. The primary end point was the incidence of 30-day periprocedural major stroke and the time to stroke postoperatively. Secondary end points included minor stroke, myocardial infarction, and overall survival.

CAD 4. “Deep-Loop” Technique for Stenting of Left Internal Carotid Artery Using Transbrachial Approach: Single-Center Experience

31 October 2018 - 11:00pm
Stenting of high-grade stenoses using distal carotid artery protection is a safe and effective method of treatment; it is a successful alternative to classic endarterectomy. The transradial and transbrachial approaches make carotid artery stenting possible, even in patients with unfavorable anatomy of the aortoiliac segment. Fang et al described an alternative strategy for the transbrachial approach called catheter looping and retrograde engagement technique or “deep loop.” The main idea is use of the right coronary cusp to provide support for placement of the catheter sheath.

CAD 3. Using Serum S100-β Protein as a Biomarker for Comparing Silent Brain Injury in Carotid Endarterectomy and Carotid Artery Stenting

31 October 2018 - 11:00pm
S100-β protein has been introduced as a sensitive biomarker of silent cerebral injury. This study aimed to compare its serum levels before, during, and 24 hours after carotid artery stenting (CAS) and carotid endarterectomy (CEA).

CAD 2. Perioperative Complication Risk Prediction According to Carotid Plaque Ulceration in 964 Consecutive Carotid Endarterectomies

31 October 2018 - 11:00pm
The role of the carotid plaque fibrous cap in carotid-related stroke risk has been demonstrated in many studies. The aim of this study was to evaluate the relationship between the presence of a carotid plaque ulcer and the perioperative complication risk in a consecutive series/cohort of patients submitted to carotid endarterectomy (CEA) at our academic tertiary hospital.

CAD 1. Computed Tomography Angiography-Derived Plaque Structural Analysis of Symptomatic and Contralateral Asymptomatic Carotid Stenosis (30%-70%): What Can Be Learned?

31 October 2018 - 11:00pm
Carotid artery disease is a major cause of stroke. The in vivo computed tomography calcified and noncalcified plaque structural components that connote carotid plaque rupture and symptoms remain ill-defined for a given degree of stenosis. We therefore analyzed computed tomography angiography (CTA) images of symptomatic patients enrolled in the Plaques at Risk (PARISK) study designed to determine the natural history of carotid stenosis (30%-70%) causing ipsilateral neurologic events.

AAN 12. Risk of Malignancy After Endovascular Aneurysm Repair

31 October 2018 - 11:00pm
Endovascular aneurysm repair (EVAR) for abdominal aortic aneurysms (AAAs) is associated with more radiation exposure compared with open surgical repair (OSR). Radiation is associated with increased risk of cancer development. We aimed to assess the risk of malignancy after EVAR or OSR.

AAN 11. Endovascular Aneurysm Sealing With Chimney Grafts—Outcomes from the First 77 Cases at a Single Institution

31 October 2018 - 11:00pm
Chimney grafts are placed parallel to an aortic stent graft to maintain perfusion through visceral branches. When they are used in combination with conventional endovascular aneurysm repair (EVAR), there is a significant risk of type I endoleak due to “guttering.” In combination with endovascular aneurysm sealing (EVAS), this risk is likely to be reduced because the polymer within the endobags conforms to the shape of the chimney stents while maintaining a proximal seal at the aneurysm neck. EVAS with chimney stents (ChEVAS) may therefore represent an alternative to fenestrated EVAR for the treatment of juxtarenal abdominal aortic aneurysms.

AAN 10. Factors Associated With Spinal Cord Ischemia After Treatment of Complex Aortic Aneurysms With Fenestrated or Branched Devices

31 October 2018 - 11:00pm
The aim of our study was to analyze the incidence of spinal cord ischemia (SCI) in patients treated with fenestrated (F-EVAR) and branched endovascular aneurysm repair (B-EVAR) and to identify risk factors associated with this complication.

AAN 8. Open Repair of Proximal Abdominal Aneurysms Analyzed According to the Anatomy, Clamping Site, and Theoretical Fenestrated Endovascular Design

31 October 2018 - 11:00pm
The objective of this study was to report our experience with open repair of hostile-necked juxtarenal, pararenal, and suprarenal aortic aneurysms (proximal abdominal aortic aneurysms) and to stratify the results according to the equivalent endovascular repair.

AAN 7. Internal Iliac Artery Flow Preservation With Iliac Branch Device During Endovascular Repair of Aortoiliac Aneurysms: Single Center Experience

31 October 2018 - 11:00pm
Iliac branch devices (IBDs) have become a popular option to preserve internal iliac artery (IIA) flow in patients with ectatic or aneurysmal common iliac arteries during endovascular aneurysm repair. This study aimed to assess the outcomes with the use of this device in a single-center setting.

AAN 6. Transcaval Embolization of Type II Endoleak After Infrarenal and Fenestrated/Branched Endovascular Aneurysm Repair

31 October 2018 - 11:00pm
Type II endoleaks are frequent after endovascular aneurysm repair (EVAR). Although mostly dissolving during follow-up, secondary rupture can occur as a persistent type II endoleak may lead to aneurysm sac growth. We aimed to investigate the outcomes of transcaval embolization (TCE) after infrarenal and fenestrated/branched EVAR.

AAN 5. Internal Iliac Artery Sacrifice During Endovascular Aneurysm Repair

31 October 2018 - 11:00pm
We aimed to assess the safety of internal iliac artery (IIA) coverage during endovascular aneurysm repair (EVAR).

AAN 4. A 14-Year Single-Center Review of Inflammatory Abdominal Aortic Aneurysm Repair

31 October 2018 - 11:00pm
The objective of this study was to review our experience with the contemporary management of inflammatory abdominal aortic aneurysms (IAAAs) involving either open surgery (OS) or endovascular aneurysm repair (EVAR).

AAN 3. Fenestrated and Branched Endovascular Repair of Aortic Arch Pathology

31 October 2018 - 11:00pm
Operative management of aortic arch disease remains a complex challenge and an area that poses significant obstacles to a totally endovascular approach. The aim of this study was to report the outcomes of custom-made fenestrated and branched endovascular aortic repair involving the arch (fEVARA and bEVARA) in our aortic center.

AAN 2. Early Experience With a Novel Thoracic Stent Design for the Prevention of Distal Stent Graft-Induced New Entry Tears (d-SINE)

31 October 2018 - 11:00pm
Distal oversizing is proposed as a contributing factor to distal stent graft-induced new entry tears, especially in managing the complications of aortic dissection. However, distal radial force can only be partially reduced by a tapered design or the use of distal restrictive stents or stent grafts. We report our early outcomes with a disease-specific, factory-modified Zenith Alpha thoracic stent graft (Cook Medical, Bloomington, Ind). Dissection-specific features include no proximal barbs; >20 cm in length and substantially tapered (custom-made, but usually by 10 mm); reduced radial force in the second and third distal stents and removal of the final stent, leaving 30 mm of unsupported graft; and an “endovascular elephant trunk.”

AAN 1. Early and Midterm Outcomes of a Custom-Made Occluding Device Based on the Najuta Endograft in Chronic Aortic Dissection

31 October 2018 - 11:00pm
Persistent flow through a false lumen in chronic aortic dissection leads to extensive dilation of the lumen with aging. To prevent aneurysm rupture, step-by-step graft replacement of the dilated aortic aneurysm segment is the most reliable procedure. However, multistage invasive surgery is limited to younger patients. A less invasive method of closing proximal entry tears using transcatheter stent graft implantation has recently been attempted. However, this procedure does not shrink dilated false lumens to expected levels.

TOI 11. Hybrid Repair for Dysphagia Lusoria

31 October 2018 - 11:00pm
Aberrant origin of the right subclavian artery (RSA) is a rare cause of dysphagia, and in some cases, the aberrant artery can become aneurysmatic (Kommerell diverticulum). Open surgical repair is the standard approach but is a major operation. As an alternative, hybrid repair has emerged as a less invasive treatment. Our objective was to describe two different options for hybrid repair of this condition.
