Craniectomy is a life-saving procedure. Subsequent cranioplasty with autologous skull bone has a bone resorption rate from 4% to 22.8% and an infection rate from 3.3% to 26%. There are concerns with their viability and the potential microbial contamination as they were explanted for a long period of time. Eighteen cranial bone flaps stored at Prince of Wales Hospital Skull Bone Bank during the period from June 2011 to March 2016 were identified. Ethics approval was obtained. Bone chips and deep bone swabs were collected for osteoblast culture and microbial culture...

BACKGROUND: Decompressive craniectomy is performed to relieve intracranial pressure as an emergency procedure. There is no large study to systematically evaluate the benefit of decompressive craniectomy versus best medical therapy. This study evaluates the survival and long-term functional outcomes of decompressive craniectomy for spontaneous intracranial hemorrhage. METHODS: A total of 54 eligible patients with spontaneous supratentorial hemorrhage (median age 55, IQR 47-64) who underwent decompressive craniectomy were retrospectively matched to 72 patients managed with best medical treatment (median age 58, IQR 32-74)...

As ancient Greeks started looking for deities that could fulfil the pragmatic needs of common people, local heroes started being mythologized and worshipped through cults. The most widespread such example was Asclepius, possibly a skilled war surgeon who followed military expeditions to Colchis and Troy. He was worshipped at religious temples called Asclepieia where certain specific medical and surgical techniques were followed. The most advanced must have been skull trepanation, most likely done as an acute operation to release intracranial pressure...

BACKGROUND: Cranioplasty after decompressive craniectomy is a common neurosurgical procedure, yet the optimal timing of cranioplasty has not been well established. OBJECTIVE: To investigate whether the timing of cranioplasty is associated with differences in neurological outcome. METHODS: A systematic literature review and meta-analysis was performed using MEDLINE, Scopus, and the Cochrane databases for studies reporting timing and neurological assessment for cranioplasty after decompressive craniectomy...

Pazopanib is a tyrosine kinase receptor antagonist used for renal cell carcinoma and soft tissue sarcoma that inhibits tumour growth and angiogenesis. A common side effect of pazopanib is hypertension. We report a case of a 69-year-old woman with clear cell renal cell carcinoma who developed a large right occipital intracerebral haemorrhage 3 weeks after initiating pazopanib. Although this was initially suspected to be a haemorrhagic metastasis, MRI revealed bi-occipital oedema, supporting a diagnosis of posterior reversible encephalopathy syndrome (PRES)...

Shigeo Kyutoku, Takayuki Inagaki
The purposes of surgery for craniosynostosis are to release increased intracranial pressure and to normalize cranial shape. The procedure was developed from a simple strip craniectomy in practice which ranged from the removal of the fused suture before the 1960s to total calvarial remodeling after 1970s and later methods of the 1990s, such as distraction and its modifications. According to its history, craniofacial surgeons might be changing their procedures with more effective, than less invasive ways. Since the late 1990s, when the distraction was applied to the craniofacial surgery, the gradual expansion, in particular of the anterior cranium, common in Japan, has long been controversial until the Caucasians accepted its use for the posterior cranium...

OBJECTIVE Decompressive craniectomy (DC) is an established part of treatment in patients suffering from malignant infarction of the middle cerebral artery (MCA) or traumatic brain injury (TBI). However, no clear evidence for intracranial pressure (ICP)-guided therapy after DC exists. The lack of this evidence might be due to the frequently used, but simplified threshold for ICP of 20 mm Hg, which determines further therapy. Therefore, the objective of this study was to evaluate this threshold's accuracy and to investigate the course of ICP values with respect to neurological outcome...

OBJECTIVE Endoscopic strip craniectomy (ESC) with postoperative helmet orthosis is a well-established treatment option for sagittal craniosynostosis. There are many technical variations to the surgery ranging from simple strip craniectomy to methods that employ multiple cranial osteotomies. The purpose of this study was to determine whether the addition of lateral barrel-stave osteotomies during ESC improved morphological outcomes. METHODS An IRB-approved retrospective review was conducted on a consecutive series of cases involving ESC for sagittal craniosynostosis at 2 different institutions from March 2008 to August 2014...

BACKGROUND: In cases of severe traumatic brain injury (TBI), cerebrospinal fluid (CSF) diversion though an external ventricular drain (EVD) is a proven method to assist in the control of elevated intracranial pressure (ICP). Under normal circumstances, the EVD is placed in a frontal location. However, in cases of multifocal intracranial injury and swelling, collapse of the frontal horns of the lateral ventricles leads to frequent failure of frontal CSF drainage. In this series we describe the utility of the Keen's point EVD as a safe alternative to maintain continuous CSF diversion for patients in whom frontal drainage is not feasible...

Posttraumatic hydrocephalus (PTH) is a disorder of disturbed cerebrospinal fluid (CSF) dynamics after traumatic brain injury (TBI). It can lead to brain metabolic impairment and dysfunction and has a high risk of clinical deterioration and worse outcomes. The incidence and risk factors for the development of PTH after decompressive craniectomy (DC) has been assessed in previous studies, but rare studies identify patients with higher risk for PTH among all TBI patients. This study aimed to develop and validate a risk scoring system to predict PTH after TBI...

INTRODUCTION: Advanced age has been traditionally associated with worse traumatic brain injury (TBI) outcomes. Although prompt neurosurgical intervention (NSI, craniotomy or craniectomy) may be life-saving in the older trauma patient, it does not guarantee survival and/or return to preinjury functional status. The aim of this study was to determine whether a simple score, based entirely on the initial cranial computed tomography (CCT) is predictive of the need for NSI and key outcome measures (e...

An 11-year-old male castrated domestic shorthair cat presented with left central vestibular dysfunction. Magnetic resonance imaging of the brain revealed a large, extra-parenchymal, strongly contrast-enhancing mass at the level of the left cerebellopontine angle and compressing the cerebellum and brainstem. The mass was surgically excised via left rostral and sub-tentorial craniectomies and histopathology revealed an epithelial neoplasm composed of anastomosing cords of neoplastic cells that contained large amounts of finely granular hypereosinophilic cytoplasm and round nuclei...

INTRODUCTION: Intracerebral hemorrhage is the second most common cause of mortality (after infections) in acute leukemia and is responsible for approximately 20% of deaths due to acute leukemia. Management of intracerebral hemorrhage (ICH) is mostly conservative but there exist certain patients who need emergent surgery due to the poor Glasgow Coma Scale (GCS) despite their coagulopathic state. CASE REPORT: We present here two such cases which were successfully managed with decompressive craniectomy which was done as a damage control surgery thus stating the importance of surgical intervention in the management of acutely deteriorating patients rather than the commonly employed conservative management due to their coagulopathic state...

OBJECTIVE Outcome studies for sagittal strip craniectomy have largely relied on the 2D measure of the cephalic index (CI) as the primary indicator of head shape. The goal of this study was to measure the 2D and 3D changes in head shape that occur after sagittal strip craniectomy and postoperative helmet therapy. METHODS The authors performed a retrospective review of patients treated with sagittal strip craniectomy at their institution between January 2012 and October 2015. Inclusion criteria were as follows: 1) isolated sagittal synostosis; 2) age at surgery < 200 days; and 3) helmet management by a single orthotist...

BACKGROUND: Decompressive hemicraniectomy (DHC) is a life-saving procedure for treatment of large malignant middle cerebral artery (MCA) strokes. Post-stroke epilepsy is an additional burden for these patients, but its incidence and the risk factors for its development have been poorly investigated. OBJECTIVE: To report the prevalence and risk factors for post-stroke seizures and post-stroke epilepsy after DHC for treatment of large malignant MCA strokes in a cohort of 36 patients...

BACKGROUND: Reconstruction of large cranial defects after craniectomy can be accomplished by free-hand poly-methyl-methacrylate (PMMA) or industrially manufactured implants. The free-hand technique often does not achieve satisfactory cosmetic results but is inexpensive. In an attempt to combine the accuracy of specifically manufactured implants with low cost of PMMA. METHODS: Forty-six consecutive patients with large skull defects after trauma or infection were retrospectively analyzed...
