Aneurysm of the proximal ulnar artery is extremely rare. Ultrasonography, computed tomography and magnetic resonance imaging generally provide accurate diagnosis of aneurysm. A 29 year-old woman who had undergone an excision biopsy of a mass in her right arm by an orthopedic surgeon was referred to our department. We resected the mass and interposed it with a reversed great saphenous vein. Histopathological examination suggested that the mass was a pseudoaneurysm consisting of organized thrombi with recanalization...

BACKGROUND AND PURPOSE: Small studies have suggested that Ehlers-Danlos syndrome (EDS) is associated with a number of cerebrovascular complications. We sought to determine whether a clinical diagnosis of EDS is associated with a higher prevalence of cerebrovascular diseases than the general population by performing a case-control study of hospitalized patients in the Nationwide Inpatient Sample (NIS). METHODS: Using the 2000-2012 NIS, we performed a case-control study matching cases of EDS to controls without such a diagnosis...

Late-onset Pompe disease (LOPD) is an adult type of classical Pompe disease and presents without cardiomyopathy. Neuroimaging in LOPD is typically limited to posterior circulation and involves dilative arteriopathy, especially dolichoectasia and intracranial aneurysms. We report an interesting case of an established diagnosis of asymptomatic LOPD in a young man with a restrictive-variant pattern in posterior vasculature. We discuss the clinical presentation, neuroimaging, existing literature, and prognosis in vascular variants of LOPD...

A variety of syndromic diseases such as Marfan syndrome, Loeys-Dietz syndrome, and bicuspid aortic valve with aneurysm along with risk factors of smoking and hypertension result in ascending aortic aneurysms and dissections. Historically, a complicated variety of terms have been used to describe a range of histopathologies that are present in resected specimens. As a result, no consistent patterns of histopathology have been reported. We used the recent Society for Cardiovascular Pathology/Association for European Cardiovascular Pathology consensus statement on nomenclature and diagnostic criteria for noninflammatory aortic disease to blindly evaluate 148 surgically resected specimens...

BACKGROUND: Although a rerupture after surgical clipping of ruptured intracranial aneurysms is rare, it is associated with high morbidity and mortality. The causes for retreatment and rupture after surgical clipping are not clearly defined. METHODS: From a prospectively maintained database of 244 patients who had undergone surgical clipping of ruptured intracranial aneurysms, we selected patients who experienced retreatment or rerupture within 30 days after surgical clipping...

Angiotensin II (AngII) promotes hypertension, atherogenesis, vascular aneurysm and impairs post-ischemic cardiac remodeling through concerted roles on vascular cells, monocytes and T lymphocytes. However, the role of AngII in B lymphocyte responses is largely unexplored. Here, we show that chronic B cell depletion (Baffr deficiency) significantly reduces atherosclerosis in Apoe (-/-) mice infused with AngII. While adoptive transfer of B cells in Apoe (-/-) /Baffr (-/-) mice reversed atheroprotection in the absence of AngII, infusion of AngII in B cell replenished Apoe (-/-) /Baffr (-/-) mice unexpectedly prevented the progression of atherosclerosis...

The renin-angiotensin-system and obesity have been implicated in vascular outward remodeling, including aneurysms, but the precise mechanisms are yet not understood. We investigated the effect of the angiotensin AT1-receptor antagonist telmisartan on aortic outward remodeling in a diet-induced obesity-model in mice. C57/Black6J mice were fed with either a low-fat diet (LFD), or a high-fat diet (HFD) for 14 weeks. One group of HFD-mice was additionally exposed to telmisartan (3mg/kg/d) for the last 4 weeks. HFD led to aortic outward remodeling, characterized by increased proteolysis, along with structural changes, such as fragmentation of elastic fibres, and decreased elastin content...

INTRODUCTION: In endovascular embolization for intracranial aneurysms, it is important to properly control the coil insertion force. However, the force can only be subjectively detected by the subtle feedback experienced by the neurointerventionists at their fingertips. The authors envisioned a system that would objectively sense and quantify that force. In this article, coil insertion force was measured in cases of intracranial aneurysm using this sensor, and its actual clinical application was investigated...

BACKGROUND AND AIMS: Evidence on the association between passive smoking and risk of aortic dissection or aneurysm is limited. This study aimed to investigate whether passive smoking increases risk of mortality from aortic dissection or aneurysm. METHODS: The Japan Collaborative Cohort (JACC) Study is a prospective community-based cohort study begun in 1988-90 and followed up to the end of 2009. We examined 48,677 individuals (mean age, 56 years; women, 46%) without history of stroke, coronary heart disease, or cancer, who provided valid responses to a lifestyle questionnaire including questions on active and passive smoking...

Anthropic actions in rivers and urban lakes are a cause for concern to our ecosystem. The effects on fauna and flora of substances discharged into waterways have become a focus for investigations globally. Biodegradable detergents are widely used in residences and small industries, but little is known regarding the consequences on fish fauna. The objective of the present study was to identify modifications in gill structure in two fish species, Astyanax altiparanae and Prochilodus lineatus, after treatment with water obtained from an urban lake and an exposure to 1 ppm diluted biodegradable detergents (linear alkylbenzene sulfonate)...

OBJECTIVE Smoking is a known risk factor for aneurysm development and aneurysmal subarachnoid hemorrhage, as well as subsequent vasospasm in both untreated individuals and patients who have undergone surgical clipping of cerebrovascular aneurysms. However, there is a lack of data in the current scientific literature about the long-term effects that smoking has on the integrity of endovascular repairs of cerebral aneurysms. This study was designed to determine if any smoking history increased the risk of poorer outcomes and/or aneurysm recurrence in patients who have had endovascular repair of cerebral aneurysms...

We present two cases of Amplatzer® device deployment that exhibited long-term failure necessitating surgical correction. The first case illustrates recanalization of a ruptured Valsalva aneurysm with worsening aortic insufficiency after percutaneous repair with the Amplatzer Vascular Plugs and Amplatzer duct occluder, while the second case illustrates recanalization after deployment of the Amplatzer septal occluder in a patient with a pseudoaneursym in a bovine aorta after type I aortic dissection repair. These two cases illustrate the potential long-term complications and limitations in durability with these devices...
