Letter to the Editor Regarding “Rupture Risk of Cerebral Arteriovenous Malformations During Pregnancy and Puerperium: A Single-Center Experience and Pooled Data Analysis”
We read with great interest the recent study by Zhu et  al1 entitled “Rupture Risk of Cerebral Arteriovenous Malformations During Pregnancy and Puerperium: A Single-Center Experience and Pooled Data Analysis.” The authors performed a retrospective study to compare risk of rupture in pregnant and nonpregnant female patients with arteriovenous malfor mation (AVM) and assess current evidence regarding rupture risk of AVM during pregnancy and puerperium by pooled data analysis. They concluded that an increase in annual rate of cerebral AVM hemorrhage during pregnancy and puerperium was found. (Source: World Neurosurgery)

Letter to the Editor Regarding “Optical Coherence Tomography in the Management of Skull Base Fibrous Dysplasia with Optic Nerve Involvement”
In the recently published article by Loewenstern et  al,1 the authors attempted to determine the utility of optical coherence tomography (OCT) in the diagnosis and management of compressive optic neuropathy secondary to fibrous dysplasia (FD). OCT is a relatively new imaging modality, which uses high-resolution cross-sections of the retina to determ ine the retinal nerve fiber layer (RNFL) thickness. The study evaluated 6 patients with cranial base FD for optic nerve compression and RNFL thinning, using computed tomography (CT) and OCT, respectively. (Source: World Neurosurgery)

Full Endoscopic Vascular Decompression: Is It What We Should Aim for?
I read with great interest the article by Dubey et  al.1 They reported a successful result of a large number of patients with trigeminal neuralgia and technical tips. I myself use endoscope for assistance to observe the dead corner behind the suprameatal tubercle and near the Meckel cave, and the panoramic view that the endoscope provides is useful for thorough observation of the cisternal portion of the trigeminal nerve. However, I am doubtful about the usefulness of totally endoscopic microvascular decompression (MVD) for several reasons. (Source: World Neurosurgery)

Endoscopic Microvascular Decompression for Trigeminal Neuralgia: Is It What We Should Aim for?
Controversy exists regarding which treatment option (full endoscopic vascular decompression or endoscopic-assisted vascular decompression) is better in the treatment of trigeminal neuralgia (TN). One group suggests that the most of the procedure should be done under a microscope and that endoscopic assistance should be undertaken to detect vessels placed anterior to the nerve and to confirm that the decompression has been performed properly. Other group believes that the whole procedure can be done safely with the use of a full endoscopic technique. (Source: World Neurosurgery)

Epistemology and the World of Neurosurgery Research
Esene et  al,1 in their brilliantly conceived and presented manuscript, “Misclassification of Case Control Studies in Neurosurgery and Proposed Solutions,” raise very good and valid points about the misclassification of published research manuscripts and potential harm done by the mislabeling or misrepr esentation of manuscript content. They eloquently demonstrate that, although many studies have been published with the inclusion of “case control study” in the title or methodology to describe the study design, often such studies are not “case control studies” but rather “cohor...

Development of a preoperative simulation technique for carotid endarterectomy in patients with contrast contraindications
Vascular and osteological parameters, such as the heights of the carotid bifurcation and distal end of the plaque, are important preoperative considerations for patients undergoing carotid stenosis procedures such as carotid endarterectomy. However, for patients with contrast contraindications such as allergies or nephropathies, three-dimensional computed tomography angiography (3D-CTA) is unavailable, and preoperative evaluation remains challenging. In the present study, we aimed to develop a preoperative simulation for use in patients with contrast-contraindicated carotid stenosis. (Source: World Neurosurgery)

Ancient observation of spinal cord injury: the case of the Assiryan lion
The description of paraplegia is considered a milestone in the history of neurology. The Egyptians provided excellent descriptions of spinal cord injuries, the Bible has several references to paraplegia, and, more recently, the pioneers of neurology described the classic syndromes related to spinal injuries and paraplegia. Here, we describe an ancient observation by the Assyrian people of paraplegia in an animal. In ancient Assyria, lion hunting was a ritualized activity conducted for political and religious purposes.

Transforaminal Endoscopic Decompression for Foot Drop Twelve Years After Lumbar Total Disc Replacment: Technical Note
Lumbar total disc replacement (LTDR) is considered for the treatment of lumbar degenerative disc disease with the hope that by preserving motion the long-term fusion complication of adjacent segment disease can be avoided. The complications of LTDR can be divided into approach-related and long-term complications. Very little has been described about the complications and treatment for complications more than 10 years after the device has been implanted. Here we describe a tranforaminal endoscopic discectomy procedure for a patient presenting with foot drop twelve years after a L5-S1 total disc replacement. (Source: World Neurosurgery)

Translaminar approach for treatment of hidden zone foraminal lumbar disc herniations: considerations on the surgical technique and pre-operative selection of patients with a long term follow-up
Lumbar disc herniation (LDH) is a common degenerative disease of the lumbar spine with a prevalence of 1-3% in population studies according to some authors.

Aim of our work is to provide a detailed description of the technical advantages and pitfalls of such approach reviewing a consecutive series of patients. (Source: World Neurosurgery)

Surgical strategy for and anatomical locations of petroapex and petroclival meningiomas based on evaluation of the feeding artery
The anterior transpetrosal (ATP) approach is the most appropriate approach for petroclival meningiomas, which are typically located from the dorsum sellae to the upper border of the internal acoustic meatus (IAM). Although neurosurgeons can resect over this area if the tumor is detached from the dura, tumors within the indication area for petroclival meningiomas is insufficient for the selection of the ATP approach because it can be difficult to evaluate whether the tumor is attached or only touching the dura.

The skull, belonging to a young adult male, presented signs of four head injuries produced by both blunt and sharp-edged instruments. The first two lesions, located on the frontal bone, were produced by blunt blows and showed signs of long-time survival. The third lesion, located on the inferior portion of the right parietal, suggests a perimortem non-penetrating linear cut probably caused b...
