BACKGROUND: Hydrocephalus is a common complication following decompressive craniectomy (DC). Ventriculoperitoneal shunt (VPS) was required for some patients before receiving cranioplasty (CP). Presence of a VPS is regarded as a risk factor for overall CP complications. METHODS: A retrospective survey was conducted on the 176 cases of traumatic brain injury (TBI) patients who underwent late (> 3 months) titanium CP (Ti-CP) in our hospital from April 2014 to July 2018...

BACKGROUND: While superficial temporal artery (STA) to middle cerebral artery (MCA) anastomosis is a beneficial treatment for hemorrhagic moyamoya disease, indeterminate mechanisms can cause rebleeding even after successful bypass surgery. The authors describe a case with a prominent collateral from the lenticulostriate artery (LSA) causing multiple recurrent hemorrhages after successful STA-MCA anastomosis. CASE: Description: A 49-year-old Japanese woman with moyamoya disease was referred to our institution after suffering intracranial hemorrhage on two occasions...

The authors present a 3D surgical video of a half and half, trans-cavernous approach for microsurgical clipping of a giant basilar tip aneurysm that recurred twice after endovascular treatment. The case refers to a 60 year-old man who presented with subarachnoid hemorrhage and was treated with coiling and with a good clinical and radiographic outcome. At three months, he was found to have recurrent filling at the neck of the aneurysm, and was treated again endovascularly with stent coiling. Three months after his second treatment, he again was found to have filling of the base of the aneurysm and was referred for microsurgical clipping...

INTRODUCTION: Chordomas are slow-growing but locally invasive tumors. Standard of care consists of surgical resection and radiotherapy when complete resection is not possible. Current literature has reached equivocal results with regards to the effect of adding radiotherapy on patient survival. Herein, we investigated the effect of adjuvant radiotherapy on patient survival. METHODS: The National Cancer Database was queried for patients diagnosed with sacral and vertebral column chordoma between 2004-2010...

OBJETIVE: The far-lateral approach (FLA) remains a challenge for neurosurgeons due to the complex anatomy of this region, especially in patients with anatomical variations. There is therefore an urgent need for better quantitative knowledge of the microsurgical anatomy of the FLA. METHODS: The study was performed using the dried skulls and atlas vertebrae of 50 Chinese adults, in which significant clinical parameters were measured. We further used twelve cadaveric heads to simulate the FLA to explore the step-by-step anatomy entailed by this procedure, enabling us to obtain key images and related information...

BACKGROUND: Chondrosarcoma is a malignant tumor that originates from mesenchymal cells that have differentiated into chondrocytes, often growing laterally, rarely seen in the cranium, and seldom seen in the saddle area. We believe that only a few cases have been reported in the literature. We report a case of pituitary fossa chondrosarcoma, which was completely resected by an extended endoscopic endonasal approach, and a literature review. CASE DESCRIPTION: A 20-year-old man was admitted to hospital with bilateral temporal headache and blurred vision, without any history of sexual dysfunction or diabetes insipidus...

The carotid sinus nerve branches off the glossopharyngeal nerve just after its appearance from the jugular foramen, descends along the internal carotid artery, and enters the carotid sinus. There have been many studies of the pathway and the course of the carotid sinus nerve and its communications with surrounding nerves. The intercommunication is exceedingly complicated. Acknowledgment of its anatomical diversity can be important in specific operations dealing with this area. Herein we review the anatomy, variations, pathology, and clinical applications of the carotid sinus nerve...

BACKGROUND: In clipping surgery, it is advantageous to dissect an adhered artery from the aneurysmal dome to achieve complete clipping. Bypass surgery is useful to reconstruct an adhered artery when dissection of the artery is technically difficult or risky. Here, we report the effectiveness of tailor-made intracranial (IC)-IC bypass to reconstruct an adhered artery in clipping surgery for middle cerebral artery (MCA) aneurysms. PATIENTS AND METHODS: A retrospective review of 384 consecutive patients presenting with MCA aneurysms between 2008 and 2016 identified four patients who underwent an IC-IC bypass during clipping surgery for reconstruction of an adhered artery...

This is the case of an 84-year old woman, found to have a symptomatic transverse sinus dural arteriovenous fistula. The transverse sinus was isolated from all venous circulation and its arterial feeders stemmed from the occipital artery, precluding both arterial and venous access for effective obliteration of the fistula. Therefore, the patient underwent a combined open surgical/endovascular approach, where the sinus was percutaneously cannulated through a single burr hole, allowing access for effective coiling of the fistula...

BACKGROUND: Dysfunction of endothelial cells (ECs) constitutes a critical factor in formatting intracranial aneurysms (IAs). However, little is known about the response of ECs to hemodynamic insults and its contribution to IA formation. METHODS AND MATERIAL: IAs models were constructed in both adult female New Zealand white rabbits and male Sprague-Dawley rats. Morphological changes of vessel wall were detected by HE staining. Molecular and cellular changes, including P120ctn and VE-Cadherin, in the median sagittal section of the artery bifurcation were analyzed by fluorescent staining...

Anterior inferior cerebellar artery (AICA) aneurysm is a rare cerebral entity and its presentation in association with a hyper-vascularized tumor is even more exceptional. In this study, we presented a patient with rare coexistent pathologies in combination of a cerebellar hypervascularized tumor with an outflow related AICA aneurysm. A one-stage procedure to remove both lesions was carried out following meticulous discussion with patient. Postoperative imaging demonstrated no residual of aneurysm and total resection of tumor which was pathologically diagnosed as hemangioblastoma (HB)...

BACKGROUND: The optimal approach of blood blister-like aneurysms (BBAs) is debated. Wrapping has been reported to be an effective strategy, but artificial materials were often used. In addition, perforator protection was difficult using this technique. In this case, we report a ruptured BBA of the left internal carotid artery (ICA) treated with a clip-reinforced wrapping technique using a Y-shaped autologous temporalis fascia to protect the posterior communicating artery (PComA). The outcome was favorable...
