Blockades of the cervical plexus are established anesthesia procedures, not only in the context of operative carotid revascularizations. Recent investigations define inner sonoanatomic landmarks as well as the importance of brain nerves for innervation in the neck region. The present practice-oriented article discusses current study results, alternative techniques (ultrasound- versus landmark-guided) and fields of application (carotid desobliteration, surgery of the shoulder, ear and infraclavicular region)...

The neural stem cell (NSC) niche in subventricular zone (SVZ) of adult mammalian brain contains dense vascular plexus, where endothelial cells (ECs) regulate NSCs by releasing plenty of angiocrine factors. However, the role of ECs-derived exosomes, a novel type of mediators of intercellular communications, in the regulation of NSCs remains unclear. In the current study, primary NSCs isolated from embryonic mouse brains form more neurospheres when cultured in the presence of human umbilical vein endothelial cells (HUVECs)...

PURPOSE: The current 1-dimensional fluid structure interaction model (FSI) for understanding cerebrospinal fluid (CSF) circulation requires pulsatility as a precondition and has not been applied to patients with continuous-flow left ventricular assist devices (CF-LVAD) where pulsatility is chronically reduced. Our study aims to characterize the behavior of CSF pressure and flow in patients with CF-LVADs using a computational FSI model. METHODS: Utilizing the computational FSI model, CSF production in choroid plexuses of the 4 ventricles was specified as a boundary condition for the model...

Ganglioneuromas are a very rare benign neural tumor, commonly derived from the ganglia of the sympathetic system, and are composed of mature Schwann cells, ganglion cells, and nerve fibres. They may arise anywhere from the base of the skull to the pelvis along the paravertebral sympathetic plexus. We report a rare case of synchronous ganglioneuroma and schwannoma, mistaken for carotid body tumor. The coexistence of these two entities in head and neck region is very rare.

Computed Tomographic Myelography (CTM) is a gold-standard imaging test for evaluating the brachial plexus and has been used for a long time. Another imaging test more recently used is Magnetic Resonance imaging (MRI), which is also part of the plexus evaluation. The purpose of this study was to determine the accuracy of MRI in diagnosing post-traumatic injuries of the brachial plexus. We conducted a Systematic Review with cross-sectional studies of diagnostic accuracy. Studies with populations presenting post-traumatic brachial plexus injury, over 16 years old, both genders, and examined by CT Myelography and MRI were evaluated...

The advent of magnetic resonance imaging (MRI) enables noninvasive measurement of cerebrospinal fluid (CSF) motion, and new information about CSF motion has now been acquired. The driving force of the CSF has long been thought to be choroid plexus (CP) pulsation, but to investigate whether this phenomenon actually occurs, CSF motion was observed in the ventricular system and subarachnoid space using MRI. Eleven healthy volunteers, ranging in age from 23 to 58 years, participated in this study. The MRI sequences used were four-dimensional phase-contrast (4D-PC) and time-spatial labeling inversion pulse (t-SLIP)...

BACKGROUND: Spinal dural arteriovenous fistulas (SDAVFs) are abnormal arteriovenous shunts between a radicular artery and the radicular vein, located in the dorsal surface of the dura sleeve, which drains in a retrograde manner into the coronal venous plexus of the spinal cord without an interposed capillary network. This result is a venous hypertension that reduces spinal cord perfusion and leads to ischemia and edema. Spontaneous resolution is extremely rare and, once symptomatic, the typical course is further progression with increased neurological impairment...

BACKGROUND: Coracoid approach is efficient and safe for brachial plexus block, and is guided by nerve stimulator or ultrasound in general. Many trials have proved that ultrasonic guidance was more efficacious than nerve stimulator guidance. We hypothesized that positioning posterior cord could enhance the anesthesia effect of coracoid approach brachial plexus block (CABPB) guided by nerve stimulator. METHODS: Eighty patients were randomized into 2 groups to receive CABPB with positioning posterior cord guided by nerve stimulator (group A) or CABPB guided by ultrasound (group B)...
