Rupture of aneurysm of sinus of Valsalva into the right atrium mimicking tricuspid valve endocarditis is a rare presentation. We review a case of spontaneous rupture of aneurysm of sinus of Valsalva into the right atrium presenting as a murmur. Transthoracic echocardiogram showed a mobile mass that appeared to be attached to the tricuspid valve leaflet with moderate tricuspid regurgitation suggestive of tricuspid valve endocarditis. The diagnosis was confirmed as spontaneous rupture of noncoronary sinus in to the right atrium by transesophageal echocardiogram...

BACKGROUND: In the setting of trauma, the etiology of intracranial hemorrhage (ICH) is frequently attributed to the physical, traumatic event. Caution should still be directed towards non-traumatic (or spontaneous) etiologies responsible for the trauma, such as hypertension, cerebral amyloid angiopathy, aneurysms, vascular malformation, and hemorrhagic infarcts. The role for immediate CT angiography (CTA) remains controversial to evaluate for non-traumatic etiologies. METHODS: A systematic review of the available literature in Medline PubMed database...

Abdominal aortic aneurysm (AAA) is a localized enlargement of the abdominal aorta, such that the diameter exceeds 3 cm. The natural history of AAA is progressive growth leading to rupture, an event that carries up to 90% risk of mortality. Hence there is a need to predict the growth of the diameter of the aorta based on the diameter of a patient's aneurysm at initial screening and aided by non-invasive biomarkers. IL-6 is overexpressed in AAA and was suggested as a prognostic marker for the risk in AAA. The present paper develops a mathematical model which relates the growth of the abdominal aorta to the serum concentration of IL-6...

BACKGROUND AND PURPOSE: Cerebral aneurysms in the posterior circulation are known to have a higher rupture risk than those in the anterior circulation. We sought to test the hypothesis that differences in hemodynamics can explain the difference in rupture rates. MATERIALS AND METHODS: A total of 117 aneurysms, 63 at the tip of the basilar artery (27 ruptured, 36 unruptured, rupture rate = 43%) and 54 at the bifurcation of the internal carotid artery (11 ruptured, 43 unruptured, rupture rate = 20%) were analyzed with image-based computational fluid dynamics...

BACKGROUND: Infectious intracranial aneurysms (IIAs) are rare entities and are often associated with septic embolus from infectious endocarditis. They may develop rapidly and carry a higher risk of rupture and mortality compared to noninfectious aneurysms. However, the development and rupture of an IIA within 48h in a patient with septic infarction patient is exceedingly rare. CASE DESCRIPTION: In this report, we describe a 25-year-old male who presented with left-sided hemiparesis and dysarthria from septic embolus to the right middle cerebral artery...

INTRODUCTION: Understanding the relationship between patient risk factors, postoperative complications, and morbidity and mortality is important when considering elective endovascular aortic aneurysm repair (E-EVAR) performed to prevent aneurysm rupture mortality. We aimed to stratify complications in E-EVAR and explore their relationship with postoperative death. METHODS: E-EVAR cases from 2012 NSQIP were identified. 30-day complications were categorized as major (MAJCX) or minor (MINCX) using the Clavien-Dindo classification...

BACKGROUND: Anterior cranial fossa dural arterio-venous fistulas (DAVFs) represent 6% of all intracranial DAVFs; characteristically they show an aggressive behaviour with high risk of intracranial haemorrhage. Peculiar anatomical features, such as feeding by the ethmoidal arteries and the pattern of venous drainage (frequently with varices that mimic aneurysmal dilatation), can be evaluated in detail only by digital subtraction angiography (DSA), which represents the "gold standard" in the diagnosis of such cranial fistulas...

Formation of an abdominal aortic aneurysm is a complex process involving aortic wall degradation. The matrix metalloproteinases (MMPs) mainly involved in this process are MMP-2 and MMP-9. Most aneurysms contain an intraluminal thrombus. It is suggested that the thrombus' thickness correlates with the risk of aneurysm rupture and may be a new prognostic factor. The purpose of the present study was to investigate enzyme protein levels in thick (A1) and thin (B1) segments of the thrombus and aneurysm wall sections A (adjacent to A1) and B (adjacent to B1)...

Morphologic characteristics of angiographic doughnut-shaped aneurysms of the intracranial internal carotid artery (ICA) have been rarely reported in the literature and were discussed only radiologically. In this case, surgical clipping was performed, and the specimen from the aneurysm was examined to correlate the pathologic findings and morphologic characteristics. A 59-year-old male presented with diffuse subarachnoid hemorrhage secondary to a ruptured vascular lesion originating from the intracranial portion of the right ICA...

OBJECTIVE Fusiform cerebral aneurysms represent a small portion of intracranial aneurysms; differ in natural history, anatomy, and pathology; and can be difficult to treat compared with saccular aneurysms. The purpose of this study was to examine the techniques of treatment of ruptured and unruptured fusiform intracranial aneurysms and patient outcomes. METHODS In 45 patients with fusiform aneurysms, the authors retrospectively reviewed the presentation, location, and shape of the aneurysm; the microsurgical technique; the outcome at discharge and last follow-up; and the change in the aneurysm at last angiographic follow-up...

Abdominal aortic aneurysm (AAA) is a common aortic disease with a progressive nature. There is no approved pharmacological treatment to effectively slow aneurysm growth or prevent rupture. Necroptosis is a form of programmed necrosis that is regulated by receptor-interacting protein kinases (RIPs). We have recently demonstrated that the lack of RIP3 in mice prevented aneurysm formation. The goal of the current study is to test whether perturbing necroptosis affects progression of existing aneurysm using the RIP1 inhibitors Necrostatin-1 (Nec-1) and an optimized form of Nec-1, 7-Cl-O-Nec-1 (Nec-1s)...

Cases of spontaneous regression of cerebral aneurysm remnant after incomplete surgical clipping have been rarely reported. This paper reports the regression of an aneurysm remnant after incomplete surgical clipping during postsurgical follow-up. A 50-year-old male presented with subarachnoid hemorrhage because of rupture of an anterior communicating artery aneurysm. An emergency clipping of the aneurysm was performed. A cerebral angiography, which was performed two weeks postoperatively, revealed an aneurysm remnant...
