Lei Xia, Ming-Xing Liu, Jun Zhong, Ning-Ning Dou, Bin Li, Hui Sun, Shi-Ting Li
Although the microvascular decompression (MVD) surgery has become an effective remedy for cranial nerve rhizopathies, it is still challengeable and may result in a fatal sequel sometimes. Therefore, the operative skill needs to be further highlighted with emphasis on the safety and a preplan for management of postoperative fatal complications should be established. We retrospectively analyzed 6974 cases of MVD. Postoperatively, 46 patients (0.66 %) presented decline in consciousness with a positive finger-nose test (or failure to be tested) after wake up from the anesthesia, whom were focused on in this study...

BACKGROUND: The basic necessities for surgical procedures are illumination, exposure and magnification. These have undergone transformation in par with technology. One of the recent developments is the compact magnifying exoscope system. In this report we describe the application of this system for surgical operations and discuss its advantages and pitfalls. METHODS: We used the ViTOM(®) exoscope mounted on the mechanical holding arm. The following surgical procedures were conducted: lumbar and cervical spinal canal decompression (n=5); laminotomy and removal of lumbar migrated disc herniations (n=4); anterior cervical discectomy and fusion (n=1); removal of intraneural schwannomas (n=2); removal of a acute cerebellar hemorrhage (n=1); removal of a parafalcine atypical cerebral hematoma caused by a dural arterio-venous fistula (n=1); microsutures and anastomoses of a nerve (n=1), an artery (n=1) and veins (n=2)...

Inadvertent dural puncture during epidural anesthesia leads to intracranial hypotension, which if left unnoticed can cause life-threatening subdural hematomas or cerebellar tonsillar herniation. The highly variable presentation of intracranial hypotension hinders timely diagnosis and treatment. We present the case of a young laboring adult female, who developed subdural hygromas and a subdural hematoma following unintentional dural puncture during initiation of epidural anesthesia.

UNLABELLED: The mediobasal temporal region (MTR) is located near the brain stem and surrounded by the eloquent neurovascular structures. The supracerebellar transtentorial approach (STA) is safe access to the posterior MTR structures, however its use for resection of anterior MTR lesions still remains controversial. The article describes the technique and outcome of surgery for different MTR structures using STA. MATERIAL AND METHODS: The paramedian STA was used in 18 patients (13 females and 5 males) for 7 years...

BACKGROUND: Volume isotropic turbo spin-echo acquisition (VISTA) is a new method similar to the 3D black-blood imaging method that enables visualization of a intramural hematoma. T1-VISTA has recently been applied in the diagnosis of intracranial arterial dissection. However, the identification of an intramural hematoma in posterior inferior cerebellar dissection (PICA-D) by T1-VISTA has only rarely been reported. CASE PRESENTATION: We herein report two patients who suffered from PICA-D complicated with ischemic stroke...

We report a case of repeated cerebral hemorrhage associated with administration of rivaroxaban and apixaban. A 74-year-old man had undergone catheter ablation for non-valvular paroxysmal atrial fibrillation in 2 years prior. Warfarin treatment was continued after successful catheter ablation, and was then changed to rivaroxaban in 1 year prior. Three months later, he developed subcortical cerebral hemorrhage in the right occipital lobe and pharmacotherapy was changed to apixaban. At the current presentation, he complained of headache and left visual field defect, and was admitted to our hospital...

UNLABELLED: The rate of Chiari malformation (CM) in a population ranges from 3 to 8 per 100,000 population. In 62-80% of cases, CM is accompanied by the development of syringomyelia (SM) at various levels. The clinical picture in these patients is a combination of CM and SM manifestations; however, SM symptoms often prevail, which creates some problems in the diagnosis of the disease and in the choice of optimal treatment. OBJECTIVE: On the basis of our own experience of surgical interventions, we aimed to clarify the indications for surgical treatment of SM associated with CM and to determine the optimal amount of surgery and the criteria for evaluation of treatment outcomes...

BACKGROUND: The incidence of intracerebellar hemorrhages approaches 5-10% of all intracerebral hematomas. The clinical presentation varies from headaches and dizziness to rapid deterioration of consciousness to the point of coma in severe cases. In order to find some concrete criteria that could influence the prognosis of these patients, we performed this retrospective study. METHODS: We retrospectively analyzed the factors influencing the outcome of 57 patients with intracerebellar hematomas treated in our clinic in the last 7 years...

A remote cerebellar hemorrhage (RCH) is a spontaneous bleeding in the posterior fossa, which can be rarely observed as a complication of spine surgery. As well as for RCH reported after supratentorial procedures, it shows a characteristic bleeding pattern defined "zebra sign". Nowadays, RCH pathophysiology still remains unknown. We performed a comprehensive review, collecting all cases of RCH after spine surgery reported in literature in order to identify the procedures most frequently associated with RCH and the possible risk factors...

Children with medulloblastomas most commonly present with signs and symptoms of elevated intracranial pressure due to obstructive hydrocephalus, especially headaches and vomiting. However, some pediatric patients present with sudden neurological deterioration due to intracerebellar hemorrhage associated with medulloblastoma, although very few reports exist that document this phenomenon. An 8-year-old girl was admitted to our emergency department who presented with sudden loss of consciousness, vomiting, and bradycardia...
