BACKGROUND Recent studies using colour-coded Doppler sonography showed that chronic impaired venous drainage from the central nervous system is almost exclusively found in multiple sclerosis (MS) patients. This study aimed to investigate the intracranial and extracranial venous anatomy and the intracerebral venous flow profile in patients with MS and healthy controls using magnetic resonance ve...
ural sinus thrombosis has been proposed as the primary event in the formation of a dural arteriovenous fistula (DAVF).1–4 However, the temporal course of development of a DAVF after cerebral sinus thrombosis has rarely been shown clinically. Venous angiography is a sensitive method for evaluating sinus thrombosis.5 However, the invasiveness of venous angiography limits its value in the follow-u...
Background: The standards describe an optimal level of performance. Do not applying medication care standard, results in different problems. This study was done in order to determine applying structure & process standards of medication care at pediatric wards . Methods: In this descriptive cross - sectional study, a sample was selected via systematic random sampling consist of 610 medicatio...
Introduction: Measurement of central venous pressure can be regarded as a beneficial guide in order to assess a patient's hemodynamic status, specifically in patient with sever sepsis and septic shock, for whom a central venous pressure of less than 8mmhg is considered as an indicator for aggressive intravenous fluid replacement. Therefore, this study aimed to investigate the ultrasonographic e...
Background & objectives: Cardiopulmonary bypass often causes a stress hormonal response with subsequent changes in hemodynamic and organ perfusion. Human studies involving cardiopulmonary bypass have shown that very low doses of ketamine can attenuate inflammatory and stress markers, without adverse effects. The aim of this study was to investigate whether low dose infusion of ketamine have hem...
percutaneous retrieval of an intracardiac central venous port fragment using snare with triple loops
peripherally inserted venous ports fracture with embolization in patients who received chemotherapy is a serious and rare complication,and few cases have been reported in children. we report a successful endovascular technique using a snare for retrieving broken peripherally inserted venous ports in a child for chemotherapy. catheter fragments may cause complications such as cardiac perforation...
background: factor v g1691a (fv leiden), fii ga20210, and methylenetetrahydrofolate reductase (mthfr) c677t mutations are the most common genetic risk factors for thromboembolism in the western countries. however, there is rare data in iran about cerebral venous and sinus thrombosis (cvst) patients. the aim of this study was to evaluate the frequency of common genetic thrombophilic factors in c...
background: by increasing the survival of immature newborns, intravenous access methods, used to provide intravenous therapy, became more important. more attention has been recently paid on peripherally inserted central venous catheters in newborns, although it is yet unknown in iran. in this study, we tried to discover the barriers to spread the usage of peripherally inserted central venous ca...
