BACKGROUND AND OBJECTIVES: Drug-coated balloons (DCBs) have exhibited promising results in coronary and peripheral artery diseases, but conclusive evidence is lacking in intracranial vasculature. We assessed the safety and efficacy of DCBs vs stent angioplasty for symptomatic intracranial atherosclerotic stenosis (sICAS) and initially identified patients who might have benefited most from DCB treatment. METHODS: A single-center, retrospective cohort study was conducted from June 2021 to May 2022 with 154 patients with sICAS divided into 2 treatment groups: a DCB group (with or without remedial stenting, n = 47) and a stent group (n = 107)...

BACKGROUND AND IMPORTANCE: A double-layer micromesh stent is designed for the treatment of carotid artery stenosis that has been reported to potentially provide a flow diversion effect. However, the actual flow diversion effect of stents remains unclear. Here, we present a case of a growing saphenous vein graft (SVG) aneurysm treated with the placement of the double-layer micromesh stent using its flow diversion effect. CLINICAL PRESENTATION: A 66-year-old woman, who underwent high-flow bypass using a SVG for a blister-like internal carotid artery aneurysm 13 years earlier at our institute, was referred to our hospital with a pulsatile cervical mass...

BACKGROUND AND OBJECTIVES: Lateralization or mobilization of the internal carotid artery (ICA) during a midline approach is required to expose lesions behind or lateral to the ICA. However, there have been no published data regarding the surgical outcomes of the endoscopic endonasal internal carotid transposition technique (EEITT). This study aimed to analyze the relevant surgical anatomy around the ICA and propose a grading scheme of EEITT. METHODS: A retrospective review of patients who underwent EEITT at a single institution was performed...

Aneurysm treatment presents various therapeutic options. Flow diverters (FD) stents are a revolutionizing endovascular technique for previously untreatable aneurysms.1 FD stents have documented success rates up to 95% and complication rates as low as 2.3%.2 This modality has proven its effectiveness and safety, but it is critical to consider potential complications. Complications include vascular-related problems such as perforation, occlusion, cerebral hyperperfusion, stent thrombosis, restenosis, and embolic events...

BACKGROUND AND OBJECTIVES: Endoscopic skull base surgery is a subspecialty field which would benefit significantly from high-fidelity surgical simulators. Giving trainees the opportunity to flatten their learning curve by practicing a variety of procedures on surgical simulators will inevitably improve patient outcomes. METHODS: Four neurosurgeons, 8 otolarynologists, and 6 expert course faculty agreed to participate. All participants were asked to perform a transsphenoidal exposure and resection of a pituitary adenoma, repair a cerebrospinal fluid (CSF) leak, control a carotid injury, and repair a skull base defect...

Cavernous malformations (CMs) are rare, often oligosymptomatic vascular lesions. Common manifestations include seizures and focal neurological deficits. Depending on the symptoms, location, size, and risk factors of bleeding, such as the presence of a developmental venous anomaly, the injury can be highly morbid. Hence, one can consider surgical resection. Deep and eloquently located CMs, such as those located in the temporal trunk, can be quite challenging and require an exact operative technique.1-7 We present a 27-year-old patient with a history of headaches that began two years ago and significantly worsened in the last month, associated with visual blurring, scotomas, nausea, phonophobia, and photophobia as well as paresthesias in the hands and perioral region...

BACKGROUND AND IMPORTANCE: Complete posterior atlantoaxial dislocation (PAAD) with an unfractured odontoid process is a rare condition where a dislocated but intact odontoid process is positioned ventrally to the anterior arch of C1. This lesion is related to transverse and alar ligament rupture secondary to hyperextension and rotatory traumatic injury and is often associated with neurological deficit. The treatment strategy remains controversial, and in many cases, odontoidectomy is required...

BACKGROUND AND OBJECTIVES: Giant pediatric craniopharyngiomas are rare tumors whose clinical and surgical management is extremely challenging. A variety of open transcranial approaches has been used to resect these lesions. Although there has been an increasing acceptance of the endoscopic endonasal approach (EEA) for the resection of pediatric craniopharyngiomas in recent years, many surgeons continue to recommend against the use of the EEA for giant pediatric craniopharyngiomas. This study aimed to evaluate the feasibility of extended EEA for giant craniopharyngiomas in the pediatric population...

BACKGROUND AND OBJECTIVES: For patients with surgical adult spinal deformity (ASD), our understanding of alignment has evolved, especially in the last 20 years. Determination of optimal restoration of alignment and spinal shape has been increasingly studied, yet the assessment of how these alignment schematics have incrementally added benefit to outcomes remains to be evaluated. METHODS: Patients with ASD with baseline and 2-year were included, classified by 4 alignment measures: Scoliosis Research Society (SRS)-Schwab, Age-Adjusted, Roussouly, and Global Alignment and Proportion (GAP)...

BACKGROUND AND IMPORTANCE: Surgery of jugular foramen tumors (JFTs) often requires vascular control by means of ligating the internal jugular vein and sigmoid sinus (SS) to allow intrabulbar access. Occlusion of the SS traditionally involves presigmoid and retrosigmoid durotomies allowing introduction of ligature devices, predisposing to cerebrospinal fluid (CSF) leakage and pseudomeningoceles. We describe a simple and novel endoluminal sigmoid sinus occlusion (ESSO) technique with Gelfoam that is entirely extradural...

Petroclival meningiomas are a challenge in skull base surgery, despite the advances in the knowledge of this pathology, there are still many controversies regarding their optimal treatment.1 The proximity and adherence to cranial nerves, major vessels such as the basilar artery, and brainstem compression explain the significant surgical risk.2,3 We present the case of a woman with a petroclival meningioma (WHO grade I) and pneumatization of the petrous apex. A tailored combined petrosal approach with a wide pedicled flap was performed for reconstruction of the pneumatized petrous apex...

Ventricular neurocysticercosis is a challenging disease that may cause obstructive hydrocephalus and require surgical intervention.1,2 Cysts of the lateral and third ventricle can be addressed by neuroendoscopy and removal of the cyst, when feasible. Surgical excision of cysts from the fourth ventricle can be achieved through endoscopic or microsurgical techniques, depending on the experience of the surgeon and characteristics of the cyst. Unresectable cysts causing hydrocephalus require cerebrospinal fluid diversion through a ventriculoperitoneal shunt...

Injury to the femoral nerve can cause femoral nerve palsy,1 resulting in severe ambulation difficulties and loss of sensory function in the anteromedial thigh and medial calf.2,3 Treatment options focus on nerve repair by direct coaptation, nerve grafting, or nerve transfer.3 If the proximal nerve stump is inaccessible, the location of nerve injury is at a distance from the site of muscle innervation, and/or there is a large nerve gap, nerve transfer may be a promising alternative treatment option.4-6 Nerve transfer uses only one coaptation site and allows for a faster recovery time due to a shorter nerve regeneration distance...

BACKGROUND AND OBJECTIVES: Previous mechanisms of opening the blood-brain barrier (BBB) created a hypertonic environment. Focused ultrasound (FUS) has recently been introduced as a means of controlled BBB opening. Here, we performed a scoping review to assess the advances in drug delivery across the BBB for treatment of brain tumors to identify advances and literature gaps. METHODS: A review of current literature was conducted through a MEDLINE search inclusive of articles on FUS, BBB, and brain tumor barrier, including human, modeling, and animal studies written in English...

BACKGROUND AND OBJECTIVES: The widespread use of endoscope and increased surgical experiences in pituitary adenomas (PAs) has raised the expectations for higher resection and cure rates. The subject that will meet this expectation in all types of adenomas is the capsule and its dissection. The purpose of this study was to go beyond the commonly mentioned pseudocapsule definition for small-sized adenomas in previous studies and to describe the capsule structure in different morphologies present in pituitary adenomas of all sizes...
