TAA17. Double-Barreled and Branched Endografting for Thoracoabdominal Aortic Aneurysm: The Hexapus Technique

October 31, 2018 - 23:00
To treat thoracoabdominal aortic aneurysm, we introduced a novel hexapus technique by double-barreled cannon stenting with two abdominal bifurcated stent grafts landing at the descending thoracic aorta, following two pairs of parallel stent grafts through bilateral axillary arteries from each of the contralateral limbs to visceral arteries and extension of ipsilateral limbs to iliac arteries (Fig 1). The creation of six branches resembles a hexapus.

TAA16. In Vitro Evaluation of Balloon-Expandable Chimney Grafts in a Silicone Model With Pulsatile Pumping System and Use of Computed Tomography Angiography

October 31, 2018 - 23:00
The objective of this study was to test and to compare the in vitro performance of balloon-expandable covered stents having the indication for use in renal arteries as chimney grafts.

TAA15. Aortic Multilayer Stenting in Extreme Vascular Emergencies

October 31, 2018 - 23:00
Multilayer stent for aortic aneurysm and dissection repair is still under debate. Nevertheless, in some extreme cases, it may serve at least as a default when other endovascular solutions as well as open surgical repair are not feasible.

TAA14. A Computational Analysis of Different Methodologies for Revascularization of the Left Subclavian Artery

October 31, 2018 - 23:00
Overstenting of the left subclavian artery (LSA) in zone 2 thoracic endovascular aortic repair (TEVAR) may cause left arm ischemia and impede cerebral blood flow. To overcome this issue, two surgical options are available: (1) left common carotid artery (LCCA) to LSA bypass and (2) branched endovascular repair with LSA branched stent graft. This work studies the hemodynamic outcomes of both surgical approaches and the role of the circle of Willis anatomy using patient-specific computational fluid dynamics (CFD) analyses.

TAA13. Treatment of Aortic Arch Diseases With Three Fenestrated Stent Grafts of In Situ Fenestration and Prefenestration

October 31, 2018 - 23:00
The objective of this study was to summarize the recent experience and outcomes of total endovascular repair of complex aortic arch diseases with three fenestrated stent grafts of in situ fenestration and prefenestration.

TAA12. Distal Pseudoaneurysm due to Late Stent Graft-Induced New Entry After Thoracic Endovascular Aortic Repair With Bolton Endograft: A Single-Center Analysis

October 31, 2018 - 23:00
Distal pseudoaneurysm (DPA), due to late stent graft-induced new entry, has a negative impact on long-term aortic remodeling and could be an under-recognized but potentially life-threatening complication after thoracic endovascular aortic repair (TEVAR). We retrospectively analyzed 100 consecutive patients who underwent TEVAR using Bolton Relay Plus or Relay NBS endograft (Terumo Aortic, Somerset, NJ) at our institute from January 2013 to May 2018 to evaluate risk factors of aortic DPA expansion.

TAA11. Pushing the Limits of Proximal Sealing Zone for Emergency Thoracic Endovascular Aortic Repair by Periprocedural Combined Embolization for Acute Thoracic Aortic Aneurysm Rupture: In the Middle of the Night

October 31, 2018 - 23:00
Inadequacy of a proximal landing zone (zone 3 or 4) is often a limitation for thoracic endovascular aortic repair (TEVAR), particularly in acute situations. We present a completely new technique of tackling this issue during emergency TEVAR for a ruptured aneurysm of the descending thoracic aorta encroaching on the lesser curvature of the arch.

TAA10. Total Supra-Aortic Trunk Coverage With New-Generation Multilayer Stents for Complex Aortic Diseases

October 31, 2018 - 23:00
We present the results of up to 36-month follow-up after complete coverage of supra-aortic trunks with new-generation multilayer stents for complex aortic diseases. A total of 29 patients with complex aortic diseases underwent thoracic endovascular aortic repair with multilayer flow modulator (MFM) stents (type A and B aortic dissection and thoracoabdominal aneurysms). All patients had the aortic arch entirely covered with the MFM stent. The primary objective was to assess whether total coverage of all cerebral vessels may lead to a neurologic event in the first 30 days after intervention.

TAA9. Type B Acute Aortic Dissections: Best Medical Treatment Versus Endovascular Approach

October 31, 2018 - 23:00
In a period of 8 years, we retrospectively analyzed 155 patients with aortic thoracic disease, identifying 79 type B dissections. Forty-three cases had arrived to our institution as acute aortic syndrome.

TAA8. Aortic Epithelioid Angiosarcoma After Endovascular Treatment of Descending Aortic Ulcer

October 31, 2018 - 23:00
Aortic epithelioid angiosarcoma is a rare disease. We report a case of epithelioid angiosarcoma of the abdominal aortic wall after endovascular treatment of descending aortic ulcer.

TAA7. Coverage of Left Subclavian Artery in Blunt Traumatic Aortic Injury Repair Is Rarely Indicated

October 31, 2018 - 23:00
Endovascular repair is the standard treatment of blunt traumatic aortic injury (BTAI). Occlusion of the left subclavian artery (LSA) is sometimes encountered for an adequate landing zone. We propose that coverage of the LSA is not necessary for BTAI with an inadequate landing zone.

TAA6. Transradial Left Subclavian Artery Embolization Through 4F Sheath

October 31, 2018 - 23:00
The objective of this study was to present our experience with transradial left subclavian artery (LSA) embolization after thoracic endovascular aortic repair (TEVAR).

TAA5. Technical Feasibility and Early Results of a Custom-Made Iliac Fenestrated Device

October 31, 2018 - 23:00
Iliac branch devices (IBDs) are undergoing rapid popularization. They allow salvage of an iliac aneurysm while preserving blood flow to the hypogastric artery. Certain anatomic criteria are necessary for the use of an iliac side branch device to be technically feasible. Custom-made fenestrated iliac stent grafts may provide an alternative when anatomic criteria for an IBD are not met. There is a paucity of data on the technical performance of these new devices. The objective of this study was to present a case series and to report immediate technical and clinical results for patients treated with custom-made Anaconda iliac fenestrated devices (Vascutek/Terumo, Inchinnan, Scotland, United Kingdom).

TAA4. Endovascular Treatment of Thoracoabdominal Aortic Aneurysms Using Multibranched Stent Grafts

October 31, 2018 - 23:00
The endovascular treatment of thoracoabdominal aortic aneurysms (TAAAs) has become the “gold standard” procedure in most vascular centers. The purpose of this study was to present our single-center experience using multibranched stent grafts to treat TAAA.

TAA3. Quick-Fenestrater in Retrograde In Situ Fenestration of Complicated Thoracic Endovascular Aortic Repair

October 31, 2018 - 23:00
Endovascular treatment of complex thoracic aorta is difficult, especially in situ fenestration of the aortic arch. We developed a new type of endovascular reconstructive device for the superior branch of the aorta.

TAA2. Different Zones (0-2) of Hybrid Debranching Endovascular Aortic Repair: Outcome and Stroke Analysis

October 31, 2018 - 23:00
The aim of this study was to summarize our single-center experience of hybrid debranching endovascular repair of arch and proximal descending thoracic aorta (DTA) as regards the midterm outcome with highlight of the rate and risk factors of stroke associated with these procedures.

TAA1. The Role of Intravascular Ultrasound for Endovascular Management of Stanford Type B Aortic Dissection: Systematic Review of the Literature

October 31, 2018 - 23:00
Thoracic endovascular aortic repair (TEVAR) is the first-line treatment of complicated acute type B aortic dissection (ATBAD). Transesophageal echocardiography (TEE) is fundamental in diagnostic and intraprocedural phases; otherwise, its role seems to be limited in case of abdominal aortic extension. Intravascular ultrasound (IVUS) with established diagnostic features may be useful in guiding endovascular procedures. A systematic literature search on the use of imaging tools was aimed at verifying the contribution of IVUS, TEE, angiography, and intraluminal phased-array imaging in the management of ATBAD.

AA15. Early Outcomes of Endovascular Aortic Aneurysm Repair in Difficult Anatomy in Thai Patients: Multicenter Study

October 31, 2018 - 23:00
The objective of this study was to prospectively compare early postoperative outcomes of endovascular aneurysm repair between favorable and difficult anatomy (hostile neck or difficult access) in abdominal aortic aneurysm (AAA) patients

AA14. Combined Urgent Transcatheter Aortic Valve Implantation and Endovascular Aneurysm Repair for Symptomatic Abdominal Aortic Aneurysm

October 31, 2018 - 23:00
Transcatheter aortic valve implantation (TAVI) and endovascular aneurysm repair (EVAR) have both been proved to be safe and increasingly attractive options for treating elderly patients with severe aortic stenosis and abdominal aortic aneurysm (AAA). In cases of imminent rupture of AAA in patients with severe aortic stenosis, valvular repair should be considered to perform an aneurysm repair safely.
