OBJECTIVE Developmental venous anomalies (DVAs) are benign anatomic variations; therefore, they are usually discovered incidentally. The aim of this article was to describe radiological findings of DVAs. METHODS A retrospective search for DVAs of the brain was performed in 1899 patients who had undergone magnetic resonance imaging (MRI) with contrast enhancement between January 1, 2005 and Ap...

PURPOSE To determine, based on preoperative imaging findings, which patients treated with endovascular abdominal aneurysm repair are at high risk for the development of persistent type II endoleaks. MATERIALS AND METHODS Preoperative computed tomography (CT) angiographies of 136 patients, treated endovascularly, were retrospectively examined for possible anatomic predictors of type II endolea...

This paper is concerned with the use of Bayesian methods in the segmentation of macular #uorescein angiographies. Fluorescein angiography is used in ophthalmic practice to evaluate vascular retinopathies and choroidopathies: Sodium #uorescein is injected in the arm's cubital vein of the patient and its distribution is observed along retinal vessels at certain times. In this task a previous and ...

Diabetic retinopathy prevention requires the screening of large numbers of patients, and examination of a huge amount of images, since diabetic patients typically have both their eyes examined at least once a year. To effectively manage all this information and the workload it produces, automatic techniques for analyzing the images are required. These techniques must be robust, sensitive and sp...

The plasma concentration, particle size, and chemical composition of high density lipoproteins (HDLs) are associated with the metabolism of triglyceride-rich lipoproteins (TGRLs). During alimentary lipemia there is active exchange of lipids and apolipoproteins between HDL and apolipoprotein B-containing lipoproteins. Whereas HDL has been assigned a protective role against the development of ath...

OBJECTIVE Although a transradial angiography is accepted as the gold standard for cardiovascular procedures, cerebral angiography has been performed via transfemoral approach in most institutions. The purpose of this study is to present our experience concerning the feasibility, efficacy, and safety of a transradial approach to cerebral angiography as an alternative to a transfemoral approach. ...

objectives: the aim of this retrospective observational study was to identify local and clinical factors related to the need of surgical repair. patients and methods: in this retrospective study, 122 (0.06%) fpas treated among 21060 patients over a period of five years were assessed. patient characteristics and therapeutic procedures were analyzed through hospital records. results: there were 1...

The basic patterns of the cerebral arteries development are highly conserved across vertebrates. Historical and recent studies based on human embryos, comparative anatomy, angiographies allowed us to better understand embryological arteries. knowledge understanding such important for neurointerventionalists interested in neurovascular diseases, especially stroke, because we may encounter unexpe...

a 48-year-old woman was admitted to the emergency department with complaints of typical chest pain, cold sweat, and dyspnea of 24 hours’ duration. she had a history of hypertension, hyperlipidemia, and diabetes mellitus for many years. on admission, her electrocardiogram (ecg) revealed normal sinus rhythm and dynamic t inversion in the precordial leads. her enzyme levels were normal. transthora...
