OBJECTIVE: We studied short-term and long-term effects of covered stent endovascular graft exclusion for the treatment of abdominal aortic aneurysm rupture. PATIENTS AND METHODS: From January 2013 to January 2016, 88 patients with fractured abdominal aortic aneurysm were enrolled in this study. Patients were divided into the control group or the open abdomen group (n=52) and the observation group or the isolated group (n=36). Patients in the control group were treated with open abdominal aneurysm resection and artificial blood vessel transplant technique, while patients in the observation group were treated with percutaneous stent graft endovascular graft exclusion...

BACKGROUND: The UK abdominal aortic aneurysm (AAA) screening programmes currently invite only men for screening because the benefit in women is uncertain. Perioperative risk is critical in determining the effectiveness of screening, and contemporary estimates of these risks in women are lacking. The aim of this study was to compare mortality following AAA repair between women and men in the UK. METHODS: Anonymized data from the UK National Vascular Registry (NVR) for patients undergoing AAA repair (January 2010 to December 2014) were analysed...

PURPOSE: We report the case of a thoracic endograft used to achieve exclusion of a ruptured proximal paranastomotic abdominal aortic aneurysm (PAAA) as a consequence of aortic ballooning. CASE REPORT: A type I proximal endoleak was evidenced following endovascular repair of a PAAA with an aortic cuff. The leak was treated with ballooning, which caused distal aortic rupture. A thoracic endograft was deployed inside the cuff, achieving complete exclusion. At 1 year, there are no signs of migration or endoleak with complete PAAA thrombosis, according to computed tomographic angiography...

BACKGROUND: Associations between atmospheric pressure and abdominal aortic aneurysm (AAA) rupture risk have been reported, but empirical evidence is inconclusive and largely derived from studies that did not account for possible nonlinearity, seasonality, and confounding by temperature. METHODS: Associations between atmospheric pressure and AAA rupture risk were investigated using local meteorological data and a case series of 358 patients admitted to hospital for ruptured AAA during the study period, January 2002 to December 2012...

Open total arch replacement (TAR) has become safer with refinements in cerebral protection techniques. The frequent extension of aortic arch aneurysms into the descending thoracic aorta customarily requires a two-staged conventional elephant trunk procedure, carrying relatively high mortality and morbidity risks and high rates of rupture in the interval between the two open surgeries. The technical demands and invasive nature of TAR has therefore precluded many high-risk patients from being surgical candidates for aneurysm repair...

PURPOSE: Surgeon-modification of commercially available aortic stent grafts represents a salvage option to treat complex aortic pathologies in high-risk patients. TECHNIQUE: A 68-year old male was referred in our hospital with a contained rupture of the visceral aorta. The patient was previously treated with an infrarenal tube graft 16 years earlier as well as with a Crawford procedure with island patch of the coeliac trunk (TC) and the superior mesenteric artery (SMA) and bypasses to both renal arteries 6 years prior to admission...

INTRODUCTION: Abdominal aortic aneurysms (AAA) account for approximately 400 deaths per year in New Zealand (NZ). Waikato Hospital caters to a diverse population comprising a high proportion of the indigenous Māori ethnic group considered to be at higher risk of mortality and morbidity. Despite these population factors, there is no screening program for AAA. The aim of this study was to further define the epidemiology and outcomes of AAA repairs in NZ to investigate the utility of implementing a population-specific screening program...

Classic Ehlers-Danlos syndrome (cEDS) is characterized by fragile, hyperextensible skin and hypermobile joints. cEDS can be caused by heterozygosity for missense mutations in genes COL5A2 and COL5A1, which encode the α2(V) and α1(V) chains, respectively, of collagen V, and is most often caused by COL5A1 null alleles. However, COL5A2 null alleles have yet to be associated with cEDS or other human pathologies. We previously showed that mice homozygous null for the α2(V) gene Col5a2 are early embryonic lethal, whereas haploinsufficiency caused aberrancies of adult skin, but not a frank cEDS-like phenotype, as skin hyperextensibility at low strain and dermal "cauliflower"-contoured collagen fibril aggregates, two cEDS hallmarks, were absent...

OBJECTIVE: We report our experience with a staged hybrid approach for the treatment of extended aortic disease, also known as "mega aortic syndrome." METHODS: A total of 15 patients (10 male, 5 female) underwent staged repair of the thoracoabdominal aorta, consisting of 3 separate stages (repair of ascending aorta and aortic arch using the frozen elephant trunk technique and hybrid thoracoabdominal repair with debranching of the renovisceral branches and stent graft implantation)...

A 94-year-old woman with rupture of a thoracic aortic aneurysm (rTAA) was referred to us. She previously underwent thoracic endovascular aortic repair and was considered to be at high risk for a conventional open operation. Therefore an endovascular procedure was planned. The proximal landing zone needed to be placed at the ascending aorta to seal a type 1a endoleak. A hybrid operation consisting of supraaortic total debranching on the common femoral artery and endovascular repair was performed. All debranched bypasses were patent and the aneurysm was excluded...

Transabdominal ultrasound elasticity imaging could improve the assessment of rupture risk for abdominal aortic aneurysms by providing information on the mechanical properties and stress or strain states of vessel walls. We implemented a non-rigid image registration method to visualize the pressure-normalized strain within vascular tissues and adapted it to measure total strain over an entire cardiac cycle. We validated the algorithm's performance with both simulated ultrasound images with known principal strains and anatomically accurate heterogeneous polyvinyl alcohol cryogel vessel phantoms...

Abdominal aortic aneurysm (AAA) is a vascular disease involving gradual dilation of the abdominal aorta. Recent studies suggest that nicotine, which is a primary component in cigarette smoke, is closely associated with the development and rupture of an AAA. Nicotine accelerates AAA development through the weakening of the vascular wall by increasing oxidative stress and matrix metalloproteinase (MMP)-2 expression. However, little is known about preventing the AAA induced by nicotine. A non-surgical means of preventing the weakening of the vascular wall before the onset of AAA by functional food factors would be a valuable option over surgery...

BACKGROUND: The most important structural proteins of the vascular wall are collagen and elastin. Genetically linked connective tissue diseases lead to degeneration, aneurysm formation and spontaneous dissection or rupture of arteries. The most well-known are Marfan syndrome, vascular Ehlers-Danlos syndrome (type IV), Loeys-Dietz syndrome and familial aortic aneurysms and dissections. OBJECTIVE: This review article addresses the current status of endovascular treatment options for important connective tissue diseases...

Abdominal aortic aneurysm is a disease seen in the elderly. Without intervention, an aneurysm can rupture which leads to death in most cases. Surgical resection was the gold standard treatment for many years but since two decades, endovascular repair has surged drastically. Less invasive and morbid than open repair, this technique has significantly evolved in the recent years. Nowadays the whole aorta can be treated with endovascular techniques in expert hands. This article presents an overview of different endovascular solutions and innovations in the management of aortic aneurysms...

BACKGROUND: Intracranial mycotic aneurysm (IMA) is a rare neurovascular disease and a well-known complication following infective endocarditis. IMAs potentially carry a high mortality risk due to intracranial hemorrhage. Therefore, initial treatment is crucial for IMA patients, but an optimal treatment strategy remains unknown. Herein, we report two cases of IMA patients treated with the current usual modalities, and we provide a comprehensive literature review to propose an optimal initial treatment strategy for IMAs...

PURPOSE: Endovascular treatment of coarctation of aorta (CoA) by self-expandable Nitinol stents is one of the recognized treatment methods and may be an alternative to surgery or balloon-expandable stent implantation for CoA but there is little information about midterm to long term results of self-expandable stents. METHODS: Sixty-two patients with CoA (40 men), with a mean age of 30.7 ± 11 years, (range 17-63 years) underwent stent implantation with Optimed self-expandable Nitinol stents between 2005 and 2014...
