From time immemorial, cerebral thrombosis used to be synonymous with arterial thrombosis. But, cerebral venous thrombosis was not uncommon but neurologists and pathologists were not properly oriented regarding cerebral venous thrombosis(CVT) specially because the anatomical knowledge were not updated and nobody actually believed that thrombosis can occur in low velocity capacitance vessels as o...

Cerebral venous thrombosis is increasing common disease in daily practice with sharing clinical nonspecific symptoms. This disorder is potentially lethal but treatable, oftenly it was overlooked in both clinical and radiologic in routine practice. Whenever, clinical suspected, prompt investigation by noninvasive imaging Magnetic resonance (MR) or advanced modilities such as cerebral venous thro...

The purpose of this article is to review the spectrum of image-based diagnostic tools used in the investigation of suspected deep vein thrombosis (DVT). Summary of the experience gained by the author as well as relevant publications, regarding vein imaging modalities taken from a computerized database, was reviewed. The imaging modalities reviewed include phlebography, color Doppler duplex ultr...

INTRODUCTION A patient post bilateral scalenectomy and firstrib resections with right subclavian artery graft anastomosis with dilated vertebral venous plexus was selected for this presentation. All magnetic resonance imaging (MRI), magnetic resonance angiography (MRA), and magnetic resonance venography (MRV) sequences were cross-referenced in order to arrive at an accurate diagnosis. Since it ...

among the causes of headache, cerebral venous and/or dural sinus thrombosis (cvt) is an important challenge because of its variable clinical presentation, having negative brain ct in up to 30% of cases and unavailability of mri in some situations. on the other hand as d-dimer (dd) test has been reported to be a sensitive test for the exclusion of venous thromboembolism, we sought whether it cou...

The paper describes one of the most researched techniques in solving Constraint Satisfaction Problems (CSPs) searching which is well-suited for declarative (non-procedural) implementation in a new programming paradigm named Control Network Programming, and how this can be achieved using the tools for dynamic computation control. Some heuristics for variable and value ordering in backtracking al...

Acute mitral regurgitation (MR) was produced in 12 dogs by closed chest partial valvulectomy and the relative contributions of MR pressure gradient (MRG), the time for regurgitant flow (VSI), and the MR orifice area (MRA) to mitral regurgitant volume (MRV) assessed. Aortic and left atrial pressures, biplane left ventricular (LV) angiography, forward flow and mitral regurgitant flow (MRF) were m...

thromboembolic phenomena are the serious consequences of assisted reproductive technology. we present a case of cerebral sinus vein thrombosis (cvst) following ovarian hyper stimulation syndrome (ohss). ten days after recovering from ohss, the patient presented in the emergency department with thunderclap headache. her magnetic resonance venography (mrv) showed occluded left transverse sinus an...

The provenance of the upper Cambrian to Upper Ordovician sedimentary rocks Tasmania and Waratah Bay in southern Victoria provides information about complex dynamic tectonic environment present during their deposition. This paper uses U–Pb detrital zircon data constrain stratigraphic comparisons reconstructions these rock sequences. Multivariate statistics are used investigate similarity between...
