Unrecognized vascular variation leading to failure of arteriovenous fistula cre...

AIMS OF THE STUDY: To describe the importance of preoperative venous and arterial mapping before choosing the best arteriovenous fistula (AVF) according to the National Kidney Foundation Dialysis Outcomes Quality Initiative (NKF-DOQI) guidelines. METHODS: We describe a case of a successful arteriovenous graft (AVG) creation after the failure of two AVF and a AVG without vascular mapping conducted before the su...

Brachiobasilic AV fistula transposition without reanastomosis: preliminary results

Background: When the venous territory is poor the brachiobasilic arteriovenous fistulae (BBAVF) could be the only option for native vascular access. Several techniques have been proposed. Our aim is to evaluate the efficiency of the brachiobasilic AV fistula with two stage elevation and transposition without reanastomosis. Materials and Methods: Observational, descriptive and prospective study. Patients submitt...

Upper limb arterial hemodynamics in high brachial artery bifurcation by color d...

Background: High bifurcation of the brachial artery is a common anatomic variant, with a prevalence of 12-20% and a challenging Doppler identification. This variant may have hemodynamic implications and compromise the success of a native arteriovenous fistula (AVF). The aim of this study is to compare the hemodynamic characteristics of the upper limb arterial axis based on the location of the brachial bifurcati...

Síndrome Cerebro-Costo-Mandibular. A Propósito de Um Caso Clínico

A Síndrome Cerebrocostomandibular é caracterizada logo ao nascimento por unia sequência de Pierre Robin grave (micrognatia grave, fenda do palato e glossoptosis) e defeitos posteriores da grade costal, ocorrendo atraso mental em 50% dos casos que sobrevivem.A morte por complicações respiratórias ocorre em 40% dos casos antes do primeiro ano de vida. Os autores descrevem um caso de Síndrome Cerebrocostomandibula...

Impregnation of cinnamaldehyde into cassava starch biocomposite films using sup...

In this work, supercritical solvent impregnation (SSI) has been tested for the incorporation of natural compounds into biocomposite materials for food packaging. Cinnamaldehyde, with proved antimicrobial activity against fungi commonly found in bread products, was successfully impregnated on biocomposite cassava starch based materials using supercritical carbon dioxide as solvent. Different process experimental...

Myocardium Contructility Characterization from Echocardiograms using Optical Flow

In this thesis we propose a method to determine the local contraction patterns of the myocardium by computing the optical flow in a sequence of echocardiograms. The displacement field describing the 2-D motion of a region-of-interest (ROI) is computed between a pair of images by solving the optical flow equations under the assumption that the 2-0 strain tensors constant within the ROI and between the pair of su...

Teleimaging Tool using ISDN

The word Teleradiology, or more generically, Teleimagiology appeared in 1980 with the first systems that allow the transmission of medical images, through a data communications network, from a place to another.
