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...

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...

We evaluated left hand function with or without obstruction of left subclavian artery for 29 cases of thoracic endovascular aortic repair (TEVAR). 18 cases of distal true aortic aneurysm were undergone surgery with simple direct closure of left subclavian artery (LSCA). The other 11 cases of true arch aneurysm were revascularized by axilla-carotid-axilla bypass grafting with TEVAR. Later 26 cases were evaluated by blood pressure, maximal grasping power, persisting duration of 60% maximal grasping power, circumferential length of upper and forearms, and simple test for evaluating hand function (STEF)...

Spinal cord ischemia(SCI) has been devastating complication of endovascular thoracic and thoracoabdominal aortic repair. Spinal cord blood supply arises from not only segmental artery, subclavian artery, hypogastric artery and these branches, but also perivertebral vasculature and paravertebral muscle and small arterial network, and risk factors of SCI were multifactorial. There are several adjuncts/strategies which are utilized to minimize the incidence of SCI: cerebrospinal fluid drainage, perioperative management of high mean arterial pressure, intraoperative evoked potential monitoring, and staged thoracoabdominal aortic repair...

Altered microRNA expression is implicated in cardiovascular diseases. Our objective was to determine microRNA signatures in thoracic aortic aneurysms (TAAs) and abdominal aortic aneurysms (AAAs) compared with control non-aneurysmal aortic specimens. We evaluated the expression of fifteen selected microRNA in human TAA and AAA operative specimens compared to controls. We observed significant upregulation of miR-221 and downregulation of miR-1 and -133 in TAA specimens. In contrast, upregulation of miR-146a and downregulation of miR-145 and -331-3p were found only for AAA specimens...

Over the past two decades there have been significant advances in the use of magnetic resonance imaging (MRI) to assess the vascular system. New imaging sequences and improvements in magnet design have enabled the creation of higher spatial resolution images. MRI is now a viable alternative imaging modality when compared to both invasive angiography and computed tomographic angiography. The use of blood pool agents has further facilitated the use of MR angiography (MRA); their high molecular weight allows for lower doses of contrast medium administration while their prolonged presence in the blood stream allows for repeated high-quality volumetric imaging of both the arterial and venous circulation...

Matrix metalloproteinases (MMPs) have been implicated in the pathogenesis of aortic aneurysm because the histology of thoracic aortic aneurysm (TAA) and abdominal aortic aneurysm (AAA) is characterized by the loss of smooth muscle cells in the aortic media and the destruction of extracellular matrix (ECM). Furthermore, AAA have evidence of inflammation and the cellular elements involved in inflammation such as macrophages can produce and/or activate MMPs This chapter focuses on human aortic aneurysm that are not due to specific known genetic causes because this type of aneurysm is the more common type...

Treatment of thoracic aortic aneurysms constitutes high mortality and morbidity rates despite improvements in surgery, anesthesia, and technology. Endovascular stent grafting may be an alternative therapy with lower risks when compared with conventional techniques. However, sometimes the branches of the aortic arch may require transport to the proximal segments prior to successful thoracic aortic endovascular stent grafting. Atherosclerosis is accounted among the etiology of both aneurysms and occlusive diseases that can coexist in the same patient...

INTRODUCTION: Kawasaki disease (KD) is an acute febrile, systemic vasculitic syndrome of unknown etiology, occurring primarily in children younger than 5 years of age. Administration of IVIG within the first 10 days after onset of fever in combination with high dose aspirin reduces the risk of coronary artery damage in KD. Though rare, giant aneurysms of the coronary arteries may develop in untreated cases and prove extremely challenging to manage. CASE PRESENTATION: A 9-month-old Caucasian boy presented to our paediatric emergency department with a 4-week history of intermittent pyrexia and irritability...

In this study, three-dimensional printing (3Dp) models and simulation surgeries (SSs) were applied in two challenging aortic cases. The first was an abdominal aortic aneurysm with a complex neck, and the second was a thoracic aortic dissection aneurysm (TADA) with an angled arch. In order to avoid unpredictable obstacles and difficulties, we made optimal surgical plans by using 3D models and virtual simulations. Based on preoperative evaluation system, the surgical plans seemed more reasonable and time-saving...

BACKGROUND: Morbidity and mortality have improved with the evolution of endovascular techniques (thoracic endovascular aortic repair [TEVAR]) for thoracic aortic disease, but results after aortic intervention in patients with end-stage renal disease (ESRD) remain unclear. The objective of this study was to evaluate outcomes of open and endovascular descending thoracic aortic repair in dialysis-dependent patients. METHODS: We identified 352 patients with ESRD on dialysis undergoing open repair (n = 136) or TEVAR (n = 216) of the thoracic aorta from 2005 to 2008 using the United States Renal Data System database...

An 84-year-old woman underwent single-debranched thoracic endovascular aortic repair for aortic aneurysm. A few hours later, malperfusion of the left upper extremity occurred. Surgical exploration revealed a tubular-shaped intima packed in the debranched graft. As computed tomography showed localized dissection in the right external iliac artery probably due to access route injury, the intima roll was thought to have migrated from the iliac artery. This extremely rare case is described in detail with a discussion of the potential mechanism...

BACKGROUND: Acute thoracic aortic dissections and ruptures, the main life-threatening complications of the corresponding aneurysms, are an important cause of sudden cardiac death. Despite the usefulness of the molecular diagnosis of these conditions in the clinical setting, the corresponding forensic field remains largely unexplored. The main goal of this study was to explore and validate a new massive parallel sequencing candidate gene​ assay as a diagnostic tool for acute thoracic aortic dissection autopsy cases...

PURPOSE: We present two different cases of chronic aortic dissection, where we opted to land the stent graft into the false lumen to treat the associated aneurysm. CASE DESCRIPTIONS: For the first case, the goal of thoracic endovascular aortic repair (TEVAR) was to exclude the aneurysm from within the false lumen, because of a slit-like true lumen. In the second case, the visceral arteries came off the false lumen, with the renal vessels from the true lumen. False lumen TEVAR was performed and the infra-renal aorta fenestrated, as to ensure adequate perfusion...
