brachial plexus injury (bpi) is an uncommon complication of median sternotomy capable of causing a permanent or transitory sensitivity and/or motor function impairment in the upper limbs. during a cardiac surgery through sternotomy, for the assessment of the thoracic cage configuration and the site of mediastinal structures, a broader surgical field may be required. if the sternal retractors ar...

introduction: median nerve (mn), one of terminal branches of brachial plexus, is commonly associated with several variations. this research aimed to review the literature related to the variations of mn from axillary region to cubital fossa. methods: we searched google scholar, science direct, springer, and pubmed electronic databases to compile reports related to the variation of mn published ...

the purpose of this study was to evaluate the therapeutic result of ct -guided celiac plexus block for managing intractable upper abdominal pain due to pancreatic carcinoma or chronic pancreatitis. we treated 22 cancer patients who were on regular narcotic medication. after an iv infusion of 10mllkg ringer's lactate solution, all patients were rolled onto prone position, and lidocaine was ...

A comparative study between anatomical landmark and nerve stimulator guided supraclavicular brachial plexus block for neurovascular variations in topographic anatomy of brachial plexus. In the backdrop of our country, nerve stimulator is still not available in many centres and many anesthetists do not yet have the proper expertise and experience in giving nerve stimulator guided brachial plexus...

Three-dimensional diffusion-weighted steady-state free precession (3D DW-SSFP) of high-resolution magnetic resonance has emerged as a promising method to visualize the peripheral nerves. In this study, the application value of 3D DW-SSFP brachial plexus imaging in the diagnosis of brachial plexus injury (BPI) was investigated. 33 patients with BPI were prospectively examined using 3D DW-SSFP MR...

Irritation of neural structures, specifically the brachial plexus outside of the cervical spine is capable of producing pain in the upper extremity. These pain patterns may be similar to pain originating from the cervical spine, presenting a diagnostic challenge. Brachial plexus block is performed at multiple levels, including interscalene, supraclavicular, infraclavicular, and axillary. Inters...

Introduction Choroid plexus tumors (CPT) are defined as papillary neoplasms originating from the epithelium of the choroid plexus within the ventricles. They are classified into mainly two types: -benign choroid plexus papillomas (CPP) (World Health Organization WHO grade I) and -choroid plexus carcinomas (WHO grade III). [1,3] An intermediate group lies between the two groups and is referred t...

Each hemisegment of the Manduca sexta larva is supplied with a subepidermal plexus of approximately 350 multidendritic neurons. An initial set of neurons, the primary plexus neurons, arise at 35-45% of embryogenesis. These neurons comprise 12-16 uniquely identifiable neurons per hemisegment that have homologues in other insect larvae. Each spreads processes across a characteristic portion of th...

PURPOSE To investigate the dynamics and distribution of toll-like receptor 4 (TLR4)-positive cells and resident tissue macrophages in the uvea during endotoxin-induced uveitis (EIU) in Wistar rats. METHODS Wistar rats (n=40) received a footpad injection of 200 microg of Vibrio cholera lipopolysaccharide (LPS), and the intensity of anterior segment inflammation was evaluated after the LPS inje...

Adult brachial plexus injuries frequently lead to significant and permanent physical disabilities. Investigating the mechanism of the injury using biomechanical approaches may lead to further knowledge with regard to preventing brachial plexus injuries. However, there are no reports of biomechanical studies of brachial plexus injuries till date. Therefore, the present study used a complex three...
