INTRODUCTION: Conventional techniques of surgical correction of arch and descending aortic diseases remains as high-risk procedures. Endovascular treatments of abdominal and descending thoracic aorta have lower surgical risk. Evolution of both techniques - open debranching of the arch and endovascular approach of the descending aorta - may extend a less invasive endovascular treatment for a more extensive disease with necessity of proximal landing zone in the arch. OBJECTIVE: To evaluate descending thoracic aortic remodeling by means of volumetric analysis after hybrid approach of aortic arch debranching and stenting the descending aorta...

Thoracic aortic aneurysm (TAA) is an increasingly recognized condition that is often diagnosed incidentally. This review discusses ten of the most relevant epidemiological and clinical secrets of this disease; (1) the difference in pathogenesis between ascending and descending TAAs. TAAs at these two sites act as different diseases, which is related to the different embryologic origins of the ascending and descending aorta. (2) The familial pattern and genetics of thoracic aneurysms. Syndromic TAAs only explain 5% of the pattern of inheritance...

Thoracolumbar paraspinal myonecrosis can be developed with various etiologies. It can induce compartment syndrome of spinal muscles and cause elevated pressure on back muscles, resulting in severe back pain. Thoracolumbar paraspinal myonecrosis is a very rare disease. There are only a few studies about paraspinal myonecrosis. Here we report a case of a spontaneous thoracolumbar paraspinal myonecrosis in a patient who had asymptomatic abdominal aortic dissection. Through this case, etiologies, clinical features, radiologic findings, and treatment options for thoracolumbar paraspinal myonecrosis are discussed...

BACKGROUND: In chronic type B aortic dissection, late distal stent graft-induced new entry (SINE) has a possible negative role in long-term aortic remodeling. This study aimed to investigate the impact of SINE occurrence on survival by evaluating true and false lumen remodeling in thoracic and abdominal segments at midterm surveillance. METHODS: This study enrolled 65 patients with chronic type B aortic dissection (DeBakey type IIIb), who had received hybrid thoracic endovascular aortic repair (TEVAR) and had completed surveillance for at least 3 years...

BACKGROUND: Endovascular simulation employing computer, animal, and static models are common and useful adjuncts for teaching endovascular procedures and developing novel, complex endovascular techniques. Unfortunately, these models lack realistic haptic feedback and thus do not faithfully replicate many of the technical challenges associated with clinical endovascular procedures (e.g., arterial calcification, rigidity, and stenosis). We sought to develop a realistic and reproducible perfused cadaver model for endovascular training, device development and research...

The timely diagnosis of aortic dissection is notoriously confounded by unreliable symptomatology. We present a previously unreported clinical sign: thoracic pain reproduced by abdominal palpation. Our case illustrates the dependence of traditional clinical features on the anatomical location of an aortic dissection and lends weight to the concept of aortic pain as being a dynamic product of inter-related changes in intraluminal pressure, volume, wall stress and diameter. The clinical sign we describe may be very specific of acute aortic pathology...

The apolipoprotein E-deficient (apoE-/-) mouse model has advanced our understanding of cardiovascular disease mechanisms and experimental therapeutics. This spontaneous model recapitulates aspects of human atherosclerosis, and allows for the development of dissecting abdominal aortic aneurysms (AAAs) when combined with angiotensin II. We characterized apoE-/- rats and hypothesized that, similar to mice, they would develop dissecting AAAs. We created rats with a 16-bp deletion of the apoE gene using transcription activator-like effector nucleases...

Endovascular fenestration on the abdominal aorta is effective for preventing visceral malperfusion in aortic dissection. We report a case of stented balloon fenestration before residual entry repair using the frozen elephant trunk technique for chronic aneurysmal dissection after ascending aortic replacement for DeBakey I aortic dissection. We recognized poor communication between the true lumen and false lumen in the abdominal aorta, and visceral perfusion depended almost entirely on the proximal large entry...

OBJECTIVES: Although open repair is the standard surgical option for dissecting descending thoracic aneurysms (DTAs) and thoraco-abdominal aorta aneurysms (TAAAs), it remains a significant challenge with considerable perioperative morbidity and mortality. We retrospectively analysed early and late outcomes of open repair for these aortic aneurysms. METHODS: Early and late outcomes were investigated for 223 consecutive patients who underwent open repair for dissecting DTA or TAAA between January 2003 and December 2014 (mean age 55 ± 16 years)...

A 72-year-old man previously treated for an abdominal aortic aneurysm (AAA) was diagnosed with the 70-mm-sized type IIIb aortic dissection. Endovascular repair was considered, but there was no stent graft passing through the 8-mm iliac graft that was used for open repair of the AAA. We sealed the 5-mm-sized intimal tear site, using an Amplatzer Vascular Plug, which successfully repaired. The patient was discharged and had no complications. Serial follow-up computerized tomography scans showed that the vascular plug was positioned without migration, and the size of the aorta decreased...

Herein, we report a rare case of type B aortic dissection that occurred after endovascular aortic aneurysm repair (EVAR). A 66-year-old man underwent successful EVAR for an abdominal aortic aneurysm (AAA). Computed tomography (CT) 2 years after EVAR showed a type B aortic dissection with stent-graft migration and AAA expansion. Juxtarenal aortic expansion precluded simple stent-graft placement. He underwent hepato-spleno-renal bypass followed by stent-graft placement just below the superior mesenteric artery...

Isolated abdominal aortic dissection (IAAD) is a rare form of aortic dissection involving usually the infrarenal part of the abdominal aorta. A 45-year-old male presented with lumbar pain and claudication. Computed tomography angiography (CTA) revealed an infrarenal IAAD extending to the left external iliac artery (EIA), causing ≥90% narrowing of the lumen. An endovascular approach was decided, with deployment of an aortic stent-graft and two balloon expandable stents in both common iliac arteries (IAs), applying the kissing stents technique...

OBJECTIVE: Isolated spontaneous dissection of the superior mesenteric artery (SMA) and celiac artery (CA) remains a rare condition; however, it has been increasingly noted incidentally on diagnostic imaging. The purpose of this study was to examine the natural history and outcomes of patients presenting with isolated spontaneous mesenteric artery dissection (SMAD). We hypothesized that most SMADs can be treated nonoperatively. METHODS: This was a single-center retrospective review of patients presenting with the diagnosis of SMAD between 2006 and 2016...

RATIONALE: The initial symptoms and signs of Takayasu arteritis vary due to the heterogeneity of affected vessels. Moreover, the vascular lesions are difficult to detect at initial presentation, making diagnosis even more challenging. Although cases of aortic dissection with arteritis history have been reported, Takayasu arteritis in men with aortic dissection as initial presentation is very rare. PATIENT CONCERNS: A 37-year-old man presenting with persistent chest and back pain for 6 days was transferred to our hospital for further treatment...

OBJECTIVE: To present a surgical strategy for aortoesophageal fistula (AEF). METHODS: From October 1999 to May 2017, 27 patients with AEF were treated at Kobe University Hospital. After 9 patients with malignancies or fish bone penetration were excluded, 18 patients who had AEF secondary to aortic lesions were investigated. The mean age was 67.2 ± 10.4 years, and the male/female ratio was 16:2. Twelve patients had a nondissection thoracic aneurysm, and 6 patients had a chronic aortic dissection...

Thoracic aortic dissection (TAAD) is one of the most common types of aortic diseases. Although surgery remains the main method of treatment, the high rate of postoperative gastrointestinal complications significantly influences the effects of surgery and the recovery process. Moreover, the mechanisms underlying this disease remain unclear. To address these problems, we examined changes in the gut microbiota in 40 thoracic aortic dissection patients with abdominal complications after surgery. Levels of white blood cells (WBC), neutrophile granulocytes (NE), alanine aminotransferase (ALT), and aspartate aminotransferase (AST) were higher in all patients after surgery...

RATIONALE: Traumatic thoracic injuries in adolescents are rare but could be connected with traumatic brain injuries (TBI) and development of chronic hypopituitarism. Early recognition of these endocrine problems is a significant challenge to clinicians. We present difficulties in diagnosis of hypothalamic-pituitary insufficiency following traumatic thoracic injury in adolescence. We also review the literature of similar cases. PATIENT CONCERNS: We present a case of a 24-years-old male...

In order to advance the state-of-the-art in computational aortic biomechanics, we investigated the influence of (i) a non-uniform wall thickness, (ii) minor aortic side branches and (iii) a non-uniform axial stretch distribution on the location of predicted hotspots of principal strain in a mouse model for dissecting aneurysms. After 3 days of angiotensin II infusion, a murine abdominal aorta was scanned in vivo with contrast-enhanced micro-CT. The animal was subsequently sacrificed and its aorta was scanned ex vivo with phase-contrast X-ray tomographic microscopy (PCXTM)...

BACKGROUND: Aortic dissections can present with a broad spectrum of signs and symptoms, making them difficult to diagnose in the emergency department (ED). Aortic dissections can cause occlusion of the coronary arteries, mimicking an acute ST-elevation myocardial infarction (STEMI). Emergency point-of-care ultrasound (POCUS) may be a useful diagnostic tool to help differentiate aortic dissection from a primary myocardial infarction. CASE REPORT: A 69-year-old man with no medical history presented to our ED complaining of chest pain...
