Introduction Brain death (BD) is the irreversible termination of the functioning of the brain. The diagnosis should be first made by clinical criteria and confirmed by using paraclinical confirmatory techniques (ancillary tests). While conventional brain angiography remains the standard method of choice, computed tomography angiography (CTA) has emerged as an alternative method. In this study, we tried to evaluate the accuracy of CTA for the diagnosis of BD. Methods In this study, we included nine patients with a clinical diagnosis of BD, confirmed by electroencephalography (EEG)...

OBJECTIVE In various disease processes, including unclippable aneurysms, a bypass to the upper posterior circulation (UPC) including the superior cerebellar artery (SCA) and posterior cerebral artery (PCA) may be needed. Various revascularization options exist, but the role of intracranial (IC) donors has not been scrutinized. The objective of this study was to evaluate the anatomical feasibility of utilizing the anterior temporal artery (ATA) for revascularization of the UPC. METHODS ATA-SCA and ATA-PCA bypasses were performed on 14 cadaver specimens...

The authors present a case with a 22-year-old man suffering from a 2 pseudoaneurysms at the temporal region following trauma. The second pseudoaneurysm was diagnosed through an astute use of digital subtraction angiography along with ultrasound to the right external carotid artery which was preferred due to the presence of a vascular pathology at the region of the trauma. During surgery, the distal and proximal ends of both aneurysms were ligated and resected. The concomitant pseudoaneurysms and the use of digital subtraction angiography should be kept in mind in such trauma patients to prevent additional surgical interventions...

Feature selection is essential in medical area; however, its process becomes complicated with the presence of censoring which is the unique character of survival analysis. Most survival feature selection methods are based on Cox's proportional hazard model, though machine learning classifiers are preferred. They are less employed in survival analysis due to censoring which prevents them from directly being used to survival data. Among the few work that employed machine learning classifiers, partial logistic artificial neural network with auto-relevance determination is a well-known method that deals with censoring and perform feature selection for survival data...

BACKGROUND: Intracranial aneurysm (IA) management is challenging. Clinicians often rely on varied and intuitively disparate ways of evaluating rupture risk that may only partially take into account complex hemodynamic and morphologic factors. We developed a prototype of a clinically-oriented, streamlined, computational platform, AView, for rapid assessment of hemodynamics and morphometrics in clinical settings. To show the potential clinical utility of AView, we report our initial multicenter experience highlighting the possible advantages of morphologic and hemodynamic analysis of IAs...

True femoral artery aneurysm is a rare vascular entity and is often associated with aortic or peripheral aneurysms. Life-threatening complications associated with peripheral arterial aneurysms include rupture, thrombosis, and embolization. In patients with multiple aneurysms, any symptomatic aneurysms should be treated first; in asymptomatic patients, the aneurysms can be repaired either simultaneously in a single operation or serially in a staged procedure. We report a case of concomitant true femoral aneurysm and bilateral iliac artery aneurysms, which were treated with a combination of open surgical and endovascular techniques...

BACKGROUND: TEVAR has dramatically expanded treatment options for patients with thoracic aortic pathology. The interaction between endografts and the dynamic anatomy of the thoracic aorta is not well characterized for repetitive physiologic stressors and subsequent issues related to long-term durability. Through 3D modeling we sought to quantify cardiac-induced aortic deformation before and after TEVAR to assess the impact of endografts on dynamic aortic anatomy. METHODS: Eight patients with acute (n = 4) or chronic (n = 3) Type B dissections, or chronic arch aneurysm (n = 1), underwent TEVAR with a single (n = 5) or multiple (n = 3) Gore C-TAG(s)...

OBJECTIVE: Although the incident risk of peripheral artery disease increases in patients with metabolic syndrome, several authors report favorable outcomes in obese patients after arterial bypass surgery. We examine the effect of the so-called "obesity paradox" and metabolic syndrome on outcomes after open aortoiliac bypass surgery. METHODS: We identified patients between 2004 and 2015 who had open surgical bypass for aortoiliac occlusive disease. We excluded patients with endovascular repair and those treated primarily for aneurysmal disease...

We present a rare case of dural arteriovenous fistula (DAVF) with subarachnoid hemorrhage and intraventricular hemorrhage due to its venous aneurysms. A 63-year-old woman was admitted for a sudden loss of consciousness. Computed tomography angiograph, magnetic resonance imaging angiography, and digital subtraction angiography revealed a superior sagittal sinus DAVF. The fistula was fed by the left middle meningeal artery and left internal carotid artery, and was drained by a right vein of Trolard, the superficial Sylvian vein, deep Sylvian vein, and basal vein to the vein of Galen...

PURPOSE: Artificial neural networks (ANN) are increasingly applied to complex medical problem solving algorithms because their outcome prediction performance is superior to existing multiple regression models. ANN can successfully identify symptomatic cerebral vasospasm (SCV) in adults presenting after aneurysmal subarachnoid hemorrhage (aSAH). Although SCV is unusual in children with aSAH, the clinical consequences are severe. Consequently, reliable tools to predict patients at greatest risk for SCV may have significant value...
