Descending thoracic aortic aneurysm rupture is a life-threatening disease associated with high rates of morbidity and mortality. Treatment in these cases is a surgical emergency. Less invasive therapies for the treatment of this pathology have been developed over time. For descending thoracic aneurysm rupture, endovascular stent grafting is less invasive, life-saving, and a unique alternative to open repair. However, this approach is subject to anatomical and logistic limitations. The purpose of the present study is to report a case of an emergency endovascular repair for a ruptured thoracic aortic aneurysm in a patient with peripheral arterial disease, and to discuss some important issues related to this approach...

Spontaneous splanchnic artery rupture is associated with up to 70% mortality. Affected vessels are often aneurysmal, secondary to atherosclerosis. We report, to our knowledge, the only case of spontaneous rupture of a branch of the left colic artery and the right gastric artery, possibly secondary to vasculitis.

OBJECTIVE: Guidelines for repair of bicuspid aortic valve-associated ascending thoracic aortic aneurysms have been changing, most recently to the same criteria as tricuspid aortic valve-ascending thoracic aortic aneurysms. Rupture/dissection occurs when wall stress exceeds wall strength. Recent studies suggest similar strength of bicuspid aortic valve versus tricuspid aortic valve-ascending thoracic aortic aneurysms; thus, comparative wall stress may better predict dissection in bicuspid aortic valve versus tricuspid aortic valve-ascending thoracic aortic aneurysms...

Aortic aneurysms are morbid conditions that can lead to rupture or dissection and are categorized as thoracic (TAA) or abdominal aortic aneurysms (AAA) depending on their location. While AAA shares overlapping risk factors with atherosclerotic cardiovascular disease, TAA exhibits strong heritability. Human genetic studies in the past two decades have successfully identified numerous genes involved in both familial and sporadic forms of aortic aneurysm. In this review we will discuss the genetic basis of aortic aneurysm, focusing on the extracellular matrix and how insights from these studies have informed our understanding of human biology and disease pathogenesis...

Acute SAH from a ruptured intracranial aneurysm contributes for 30% of all hemorrhagic strokes. The bleeding itself occurs in the subarachnoid space. Nevertheless, injury to the brain parenchyma occurs as a consequence of the bleeding, directly, via several well-defined mechanisms and pathways, but also indirectly, or secondarily. This secondary brain injury following SAH has a variety of causes and possible mechanisms. Amongst others, inflammatory events have been shown to occur in parallel to, to contribute to, or even to initiate programmed cell death (PCD) within the central nervous system (CNS) in human and animal studies alike...

INTRODUCTION: There is increasing acknowledgement that surgical care is important in global health initiatives. In particular, neurosurgical care is as limited as 1-to-10 million people in parts of the world. We performed a systematic literature review to examine the worldwide incidence of central nervous system vascular lesions (CNS-VL) and a meta-analysis of aneurysmal subarachnoid hemorrhage (ASAH) in order to define the disease burden and inform neurosurgical global health efforts...

Pseudoaneurysms arise from a disruption of arterial wall continuity and are most commonly related to a penetrating trauma, an arterial wall inflammation or iatrogenic causes. They differ from real aneurysms due to a lack of one or more layers of the arterial wall. The frequency of peripheral artery pseudoaneurysms in the upper extremities is less than in the lower extremities and its most common cause is a gunshot or a stab wound. The risk of a rupture is higher than in true aneurysms due to a lack of wall layers, therefore requiring surgical treatment in most cases...

It is not fully established whether leukocyte can predict the poor outcome for ruptured cerebral aneurysms (CA) or not. Here, we retrospectively analyzed the clinical data of 428 patients with ruptured CA between 2010 and 2015. Patients' demographic data, including gender, age, history of smoking, alcohol, hypertension, diabetes and hypercholesterolemia, Hunt-Hess and Fisher grade, occurrence of hydrocephalus, aneurysm location, time to surgery, delayed ischemic neurological deficit (DIND) and peak leukocyte of blood test from day 1 to 3 after aneurysmal rupture were recorded and analyzed...

OBJECTIVE/BACKGROUND: Predicting outcomes prior to elective abdominal aortic aneurysm repair (AAA) requires critical decision making, as the treatment offered is a prophylactic procedure to prevent death from a ruptured AAA. The aim of this work was to develop and validate a model that may predict outcomes for patients with an AAA and hence aid in clinical decision making. METHODS: A discrete event simulation model was built to simulate the natural history of a patient with an AAA and to predict the 30 day and 2-5 year survival of patients undergoing treatment and surveillance...

We present a case of posterior ventricular septal rupture associated to left ventricular aneurysm manged, during peri-operative period, by transthoracic and transesophageal echocardiography. Three-dimensional transesophageal echocardiography findings add adjunctive and more accurate information regarding morphological details of the ventricular septal rupture rather than two-dimensional echocardiography, allowing, meanwhile, the detection of the outcome of the surgical repair.

The high spatial resolution of cardiac computed tomography (CT) and cardiac magnetic resonance (CMR) permit the diagnosis of congenital ventricular outpouchings (CVOs), including congenital ventricular diverticula (CVD), congenital ventricular aneurysms (CVA), clefts, and crypts. A unique classification has not been established, and these terms are used interchangeably with confounding terminology. Moreover, their significance is not univocal. A research was performed using PubMed on six subjects: (1) congenital left ventricular outpouchings; (2) congenital ventricular diverticulum; (3) congenital ventricular aneurysm; (4) ventricular clefts; (5) ventricular crypts; and (6) ventricular crevices...

Background: Vascular anomaly and aneurysmal formation of an anterior communicating artery (Acom) complex has often been reported. Because of such a complicated relationship between the vascular structure and aneurysms, Acom aneurysm is one of the most difficult aneurysms to treat among other common anterior circulation aneurysms. We experienced an extremely rare and difficult-to-treat case of ruptured Acom aneurysm with the combined vascular anomaly of the Acom fenestration and an accessory anterior cerebral artery (ACA)...

The anterior communicating artery is a common location for intracranial aneurysms. Compared to surgical clipping, endovascular coiling has been shown to improve outcomes for patients with ruptured aneurysms and we have seen a paradigm shift favoring this technique for treating aneurysms. Access to the anterior cerebral artery can be challenging, especially in patients with tortuous anatomy or subarachnoid hemorrhage or in patients presenting with vasospasm. We present a technique for cannulating the anterior cerebral artery using a balloon inflated in the proximal middle cerebral artery as a rebound surface...
