OBJECTIVES AND BACKGROUND: The aims of this study were to develop a test of competence in endovascular aortic repair (EVAR) stent graft sizing and selection; to examine the test for evidence of validity; and to explore the experience required for the task. METHODS: The test was developed based on a literature review resulting in 22 anatomical assessment points and a graft selection. Validity evidence was explored in an international cross sectional study. Twenty-two consultants with varying levels of experience in the field (novices, intermediates, and experts) were presented with computed tomography angiography of the aortic vessels from three patients...

Objectives The results after aneurysm repair with an endovascular aneurysm sealing (EVAS) system are dependent on the stability of the aneurysm sac and particularly the intraluminal abdominal aortic thrombus (ILT). The postprocedural ILT volume is decreased compared with preprocedural ILT volume in aortic aneurysm patients treated with EVAS. We hypothesize that ILT is not stable in all patients and pressurization of the ILT may result in displacement of fluids from the ILT, no differently than serum is displaced from whole blood when it settles...

This review analyzed the incidence, mechanisms, and risk factors of aortic-related reintervention after endovascular repair of chronic dissections. The systematic review identified 28 studies describing 1,249 patients at median 27 months follow-up (range, 10.3 to 64.4). There were six reinterventions, 0.7 ruptures, and 1.2 surgical conversions per 100 patient-years of follow-up. Stent-related reinterventions were more frequent than nonstent related (80.2% vs 19.8%). Distal false lumen perfusion was the most common complication (40...

BACKGROUND: Reconstruction of the aortic major branches during thoracic endovascular aortic repair is complicated because of the complex anatomic configuration and variation of the aortic arch. In situ laser fenestration has shown great potential for the revascularization of aortic branches. This study aims to evaluate the feasibility, effectiveness, and safety of in situ laser fenestration on the three branches of the aortic arch during thoracic endovascular aortic repair. METHODS AND RESULTS: Before clinical application, the polytetrafluoroethylene and Dacron grafts were fenestrated by an 810-nm laser system ex vivo, which did not damage the bare metal portion of the endografts and created a clean fenestration while maintaining the integrity of the endografts...

A right-sided thoracoabdominal aortic aneurysm involving a right-sided aortic arch is extremely rare. Surgical treatment for a right-sided thoracoabdominal aortic aneurysm is challenging due to the anatomical complexity. We report a case of a right-sided thoracoabdominal aortic aneurysm with a right-sided aortic arch successfully treated by hybrid visceral debranching and endovascular repair.

The treatment of thoracoabdominal aortic aneurysms in great vessels is still challenging, as the early results of the operation are not very promising compared with other aortic operations, and the incidence of spinal cord ischemia is relatively high. In Japan, which is becoming a super-aging society, the method of performing minimally invasive operations remains a major issue. At our facility, we have been performing abdominal debranching thoracic endovascular aortic repair (TEVAR) to resolve these issues...

Our treatment strategy for acute type B aortic dissection (ABAD) included complicated type is as follows. Indications of thoracic endovascular aortic repair (TEVAR) for ABAD are rupture and organ ischemia, and TEVAR has been the 1st line central repair therapy since January 2009 in our institution. At the time of TEVAR for ruptured communicating type ABAD, we usually seal the proximal entry tear and cover the existing range of hematoma at descending aorta. Procedures for ABAD with malperfusion should be changed according to the patient's condition such as branch vessel obstructions either dynamic type or static type...

We classified 59 patients who underwent thoracic endovascular aortic repair for uncomplicated type B aortic dissection from April 2008 to April 2016 into 3 groups based on time from onset and maximum aortic diameter:SA (2weeks to 1 year since onset;n=29), C (>1 year since onset;n=17), and D(maximum aneurysm size≥60 mm;n=13). We used the Kaplan-Meier method tso analyze survival, major adverse cardiovascular event and the need for additional treatment. There was no significant difference in outcomes between the SA and C groups (p=0...

The method of hybrid arch thoracic endovascular aortic repair (TEVAR) to treat aneurysm with zone 0 landing has changed according to its invasiveness and complications. The real chimney technique allows supra-aortic bypass from ascending aorta without side clamp is the current choice of treatment. The comprehensive strategy to prevent stroke during hybrid arch TEVAR consisting of magnetization-prepared rapid acquisition with gradient-echo for evaluation of the atheromatous change and balloon protection of the left subclavian artery has contributed for the marked reduction of stroke...

Thoracic endovascular aortic repair (TEVAR) combined with all-neck-branch reconstruction (total debranching TEVAR)[td TEVAR] is applied to aortic arch aneurysms as a minimally invasive procedure to improve treatment results. We report the initial and long-term results of td TEVAR for the reoperation of aortic arch aneurysm. By September 2016, td TEVAR for reoperation had been applied in 5 cases. The reasons for the reoperation were dilation of the arch aneurysm after ascending aorta replacement in 4 cases and localized dissection of the proximal landing zone after zone 2 TEVAR in 1 case...

Thoracic endovascular aortic repair( TEVAR) for thoracic aortic aneurysm has been established as a 1st-line therapy, especially in high-risk cases, with device improvements and the appearance of various procedures, but there are still cases of anatomical adaptation. On the other hand, several countermeasures have been developed, but there are no commercially available devices for fenestrated or branched stent grafts in Japan. Moreover, complications such as cerebral infarction, organ ischemia and bypass occlusion and infection are pointed out in popular debranch TEVAR...
