A Microsurgical Training Model For Anterior Cervical Discectomy in Fresh Sheep Spine
No full textThe main purpose of this study is to develop a practical microscopic training model of a fresh cadaveric sheep cervical spine that simulates the human anterior cervical discectomy under operating microscope. According the study results, it has been claim that this model simulates well standard anterior cervical discectomy of the human spine and is a useful method for trainees
An Unusual Mechanism of Delayed Intracerebral Hemorrhage After Ventriculoperitoneal Shunting: Case Report
No full textWe present a case of delayed intracerebral hemorrhage that developed seven years after initial ventriculoperitoneal shunt surgery. A seven-year-old boy was admitted to emergency when he experienced sudden headache and vomiting. Computed tomography (CT) scanning showed an intracerebral hemorrhage around the ventricular catheter that cannot be explained by known predisposing factors such as head trauma, coexisting bleeding disorder, occult vascular malformation, and intratumoral hemorrhage. The presumed mechanism in this case is that the ventricular catheter caused contusion of cerebral tissue because the shunt tube at the neck had stretched during the growing up of the child
A Variation of the Cords of the Brachial Plexus on the Right and a Communication between the Musculocutaneous and Median Nerves on the Left Upper Limb: A Unique Case
No full textDuring routine anatomical dissection of the upper extremity of a 64-year-old cadaver for educational purposes, we observed variations in the brachial plexus on each side. On the right an anomaly of cord formation was present and on the left there was a communication between the musculocutaneous nerve (MCN) and median nerve (MN). On the right side the brachial plexus showed two trunks, superior (C5 and C6) and inferior (C7, C8, and T1); the middle trunk was absent. The superior trunk bifurcated into anterior and posterior divisions, the anterior division continued as the lateral cord forming the MCN. The posterior division gave off the subscapular branch. The inferior trunk trifurcated into radial, median, and ulnar nerves. The radial nerve gave off the axillary and thoracodorsal nerves. The ulnar nerve gave off the median cutaneous nerves of the arm and forearm. The median nerve received a small ascending branch from the MCN. On the right side, there was a communicating branch from the MCN to the MN in the lower third of the arm region. This communicating branch also gave rise to a muscular branch to the brachialis muscle and the lateral cutaneous nerve of forearm. No additional heads of the biceps brachii muscle were observed in either upper limb. Knowledge of the variations of the brachial plexus in humans can be valuable for operations of the shoulder joint and its repair for providing an effective block or treatment for anesthetists and also for explaining otherwise incomprehensible clinical signs for neurologists
Falcine venous plexus within the falx cerebri: anatomical and scanning electron microscopic findings and clinical significance
No full textThe falcine venous plexus is a network of venous channels that exists within the connective tissue of the falx; the sizes and patterns of communication of these structures showed regional differences. Neurosurgeons should be aware of the regional differences when making an incision or puncturing the falx during a surgical approach
The denticulate ligament: anatomical properties, functional and clinical significance
No full textDL histology and anatomy are strongly correlated with the function of this structure at different spinal levels. It is important to have accurate knowledge about DLs as these structures are relevant for clinical procedures that involve the spinal cord or craniovertebral junction
Intradural communication between dorsal rootlets of spinal nerves: their clinical significance
No full textSuch communications may lead to misinterpretation of the pathology on the basis of clinical signs and symptoms and also should be considered in rhizotomy
Influence of Prior Lumbosacral Surgery on The Incidence of Intravascular Injection During Transforaminal Epidural Injections
No full textConclusion: Our results indicated that previous surgery affected intravascular dissemination and increased the risk of vascular injection. Cohesional area caused by previous surgery complicated the injection. Additionally, fluoroscopy count and operation time were also affected by previous surgery
The Supraorbital Keyhole Approach
No full textConclusions: This anatomical study showed that structures in the anterior and middle cranial fossa can be reached via the supraorbital keyhole craniotomy approach with minimal brain retraction and adequate exposure and with minimal craniotomy size
Laboratory Training in Bifrontal and Frontolateral Approaches Using Cadaveric Silicone-Injected Cow Craniums
No full textConclusion: The aim of this study was to develop an innovative model to create a life-like microneurosurgical training system. This model simulates bifrontal and frontolateral approaches performed on the human brain
Vascular Silicone Injection of Fresh Cadaveric Cow Cranium: Alternative Training Model For The Human Brain
No full textConclusion: Silicone injection of the cadaveric cow brain, based on the anatomical and physiological assessment of the vasculature of the specimen for microanatomical studies, is suggested as an alternative to using human brain specimens
