BACKGROUND: Bypass surgery for complex intracranial aneurysms (IAs) results in drastic blood flow changes in intracranial arteries. The aim of the study was to elucidate how vessels adapt to blood flow changes after bypass surgery with phase-contrast magnetic resonance imaging (PC-MRI). METHODS: This is a prospective observational study to assess changes of the blood flow in intracranial arteries after bypass surgery for IAs. Flow rates and vessel diameters were measured with PC-MRI in 52 intracranial arteries of 7 healthy volunteers and 31 arteries of 8 IA patients who underwent bypass surgery...

OBJECTIVE: Injuries of the upper trunk of the brachial plexus may trigger motor and sensory deficits. There exists a growing body of literature with respect to the reconstruction of motor deficits in upper trunk brachial plexus injuries by using nerve transfers; albeit to date, very few old reports have focused on the reconstruction of sensory loss resulting from upper trunk injuries. In this case series, we review six cases (five males and one female) with upper trunk brachial plexus injuries undergoing sensory nerve transfers...

BACKGROUND: According to our research, just few studies described 5-Aminolevulinic acid (5-ALA) use for spinal injuries resection. 5-ALA is known to be especially useful in certain spinal tumor entities such as meningiomas, ependymomas, hemangiopericytomas, and metastasis of central nervous system primary tumors. In contrast, 5-ALA has limited value in other histopathological tumoral entities, as neurinomas and carcinoma metastasis. METHOD: We describe a microsurgical resection of a spinal cord melanoma through fluorescence-guided technique using 5-ALA in a 36-year-old man...

BACKGROUND: Eloquent area surgery has become safer with the development of intraoperative neurophysiological monitoring and brain mapping techniques. However, the usefulness of intraoperative electric brain stimulation techniques applied to the management and surgical treatment of cavernous malformations in supratentorial eloquent areas is still not proven. With this study, we aim to describe our experience with the use of a tailored functional approach to treat cavernous malformations in supratentorial eloquent areas...

BACKGROUND: Due to improved diagnostic methods, the incidence of brain abscess is still rising. Therefore, clear and evidence-based therapy for the patients who suffer from brain abscesses is necessary. Brain abscesses are potentially life-threatening conditions that possibly lead to permanent injuries even after sufficient healing has taken place. The aims of this study were to analyze the clinical aspects of patients with brain abscesses and thereby to reveal the relevant aspects for the future treatment of the brain lesions...

BACKGROUND: Surgeries for far-lateral lumbar disc herniation (FLLDH) and foraminal stenosis at the L5/S1 level are very complicated because of its unique structure. The authors have performed unilateral bi-portal endoscopy (UBE) to these lesions because of the good results obtained for other spinal diseases (Park et al. in Orthopedics 40:e779-e783, 2017). METHODS: We described our experience of the surgical treatment for FLLDH and foraminal stenosis. Useful information for pre-, intraop-, and postoperative care is presented...

BACKGROUND: Device infection is a major complication of placement external ventricular drains (EVD). Diagnostic features are often masked by underlying disease or cerebrospinal fluid (CSF) contamination by blood. We aim to assess which diagnostic modalities are applied for EVD-related infection (ERI) diagnosis and evaluate their accuracy. METHODS: This observational prospective study included 187 adult patients with an EVD. Modalities of clinical diagnosis of ERI diagnosed by treating physicians on clinical grounds and blood and CSF analysis (clinically diagnosed ERI (CD-ERI)) were assessed prospectively...

BACKGROUND: In surgical treatment of acute subdural hematoma (ASDH), neurosurgeons frequently encounter bleeding from cortical arteries, which is usually controlled with bipolar coagulation. However, bipolar coagulation is associated with a risk of sacrificing the cortical artery, which may affect the prognosis of neurological symptoms when these cortical arteries supply critical areas. In this article, we describe microsurgical repair of damaged cortical arteries using a 10-0 nylon micro-suture in patients with arterial-origin ASDH...

BACKGROUND: Left ventricular assist devices (LVADs) were developed for the treatment of patients with severe heart failure (HF) as a bridge to heart transplantation (HT). Although long-term LVAD support results in substantial improvements, their long-term use often leads to severe acute ischemic stroke (AIS). Serious neurological events make it difficult to continue LVAD support, and these patients are excluded as candidates for HT. AIS remains a challenging problem in patients receiving LVAD support...

BACKGROUND: To evaluate the significance for outcome of meningioma invasion into the internal auditory canal (IAC) in posterior fossa meningiomas. METHODS: From April 2005 to September 2015, 174 posterior fossa meningiomas have been surgically treated in our Institution. Careful analysis of preoperative MRI depicted in 63 cases (36%) meningioma invasion into the IAC. A retrospective analysis was done of clinical and radiological presentation, surgical findings, outcome, and relevant prognostic factors in order to stratify the risk of complication and evaluate the surgical outcome...

We present the case of a patient who died of a fatal meningoencephalitis after removal of a third ventricle colloid cyst. Postoperative clinical and iconographic evolution let us think about an acute disseminated encephalomyelitis probably due to cerebrospinal fluid contamination by inflammatory proteins contained in the colloid cyst. This case raises the question of a possibility of colloid cyst content spraying while using an ultrasonic aspiration device.

BACKGROUND: Traumatic brachial plexus injuries are generally severe, and in many cases associated with surrounding tissue injuries, which makes them hard to diagnose at the right time. This paper presents etiological and epidemiological characteristics of surgically treated civilian traumatic brachial plexus injuries. METHODS: This retrospective study included 68 patients, operated due to the traumatic brachial plexus injuries at Clinic for Neurosurgery, Clinical Center of Serbia, during the 11-year period...

BACKGROUND: Although paraclinoid aneurysms do not exhibit a high risk of rupture, coil embolization is not always easy because of unstable microcatheter position. We present a technique that allows a stable microcatheter position for coil embolization of paraclinoid aneurysms. METHODS: We enrolled 34 consecutive patients who underwent coil embolization for paraclinoid aneurysms. A loop of distal microcatheter was shaped based on three-dimensional rotational angiography...

BACKGROUND: Arterial injury related to stent strut is rare during stent-assisted coil embolization. METHOD: The patient underwent stent-assisted coil embolization for a right middle cerebral artery aneurysm. At this time, the parent arterial injury at M1 portion of the middle cerebral artery resulted in subarachnoid hemorrhage. The arterial penetration caused by the stent strut was repaired with wrap-clipping. RESULTS: Postoperative angiograms demonstrated the complete obliteration of the arterial injury...

BACKGROUND: Post-traumatic hydrocephalus (PTH) is one of the main complications of decompressive craniectomy (DC) after traumatic brain injury (TBI). Then, the recognition of risk factors and subsequent prompt diagnosis and treatment of PTH can improve the outcome of these patients. The purpose of this study was to identify factors associated with the development of PTH requiring surgical treatment in patients undergoing DC for TBI. METHODS: In this study, we collected the data of 190 patients (149 males and 41 females), who underwent DC for TBI in our Center...

BACKGROUND: Registration accuracy is a main factor influencing overall navigation accuracy. Standard fiducial- or landmark-based patient registration is user dependent and error-prone. Intraoperative imaging offers the possibility for user-independent patient registration. The aim of this paper is to evaluate our initial experience applying intraoperative computed tomography (CT) for navigation registration in cranial neurosurgery, with a special focus on registration accuracy and effective radiation dose...
