RESUMO

An effect of the COVID-19 pandemic was the disruption of healthcare systems, especially surgical services provided to the community. Pituitary surgery was especially impacted, given the majority of cases were deemed non-urgent with very few exceptions, and the high risk of viral transmission conferred by the endoscopic endonasal transsphenoidal approach. Patients suffering from pituitary lesions with resultant endocrinopathy or visual symptoms saw their treatment delayed or altered, which had implications on their outcomes and care. This disruption extended to surgical training and the usual functioning of academic units, necessitating changes to curricula and implementation of novel methods of progressing surgical education. This review will explore the effect of the COVID pandemic on pituitary surgery, the experiences of various surgeons as well as the adaptations implemented on the frontlines. The lessons learned from the experience of the pandemic may assist specialists in gleaning insights regarding the care of patients in the future.

RESUMO

STUDY DESIGN: Narrative review. OBJECTIVE: Metastatic spine disease is an increasingly common clinical challenge that requires individualised multidisciplinary care from spine surgeons and oncologists. In this article, the authors describe the recent surgical advances in patients presenting with spinal metastases. METHODS: We present an overview of the presentation, assessment, and management of spinal metastases from the perspective of the spine surgeon, highlighting advances in surgical technology and techniques, to facilitate multidisciplinary care for this complex patient group. Neither institutional review board approval nor patient consent was needed for this review. RESULTS: Advances in radiotherapy delivery and systemic therapy (including immunotherapy and targeted therapy) have refined operative indications for decompression of neural structures and spinal stabilisation, while advances in surgical technology and technique enable these goals to be achieved with reduced morbidity. Formulating individualised management strategies that optimise outcome, while meeting patient goals and expectations, requires a comprehensive understanding of the factors important to patient management. CONCLUSION: Spinal metastases require prompt diagnosis and expert management by a multidisciplinary team. Improvements in systemic, radiation, and surgical therapies have broadened operative indications and increased operative candidacy, and future advances are likely to continue this trend.

RESUMO

BACKGROUND: Tension pneumocephalus (PMC) is a rare and feared complication following the endonasal endoscopic approach (EEA) to skull base procedures. This is a neurosurgical emergency that requires urgent decompression to avoid catastrophic neurologic damage or death. An avoidable cause is the application of positive pressure ventilation (PPV) in EEA patients for postoperative hypoxia. Our institution implemented a hospital-wide protocol in response to this to identify and manage at-risk patients; this paper aims to identify if this protocol was effective in lowering the rates of tension PMC secondary to PPV. RESULTS: In the 3 years following the implementation of the protocol, 110 patients underwent EEAs, from which 1 case of tension PMC (found to be not secondary to PPV) was identified. This is compared with 2 cases of tension PMC secondary to PPV over the preceding 5 years, out of 406 EEA patients. This constitutes a quantifiable reduction in PPV-related tension PMC in both standard and extended approach EEAs, signifying the effective uptake of the protocol. CONCLUSIONS: We found no cases of tension PMC after PPV following EEA skull base surgery in our institution since the implementation of an institution-wide guideline. This underscores the utility of our simple and cost-effective preventative protocol in reducing the overall rates of tension PMC following the inadvertent postoperative application of PPV. Further research is needed to study the comparative risks and benefits of PPV in the post-EEA patient and thus inform future iterations of the protocol.

RESUMO

BACKGROUND AND OBJECTIVES: Surgical evacuation with placement of a postoperative drain is the standard treatment for symptomatic chronic subdural hematoma (cSDH). Subdural and subgaleal drains are equally effective after burrhole craniostomy, but the optimal location of the drain after craniotomy is not clear. We sought to compare the clinical and radiological outcomes of subdural and subgaleal drain placement in patients undergoing minicraniotomy for cSDH. METHODS: A retrospective review of 137 consecutive patients undergoing minicraniotomy for cSDH at a single institution was performed. Cases were stratified by location of postoperative drain. The primary outcome was change in functional status (modified Rankin Score, mRS) at 3 months from preoperative baseline. RESULTS: Among the patient cohort, 24.6% received subgaleal drain placement. After a median follow-up of 105 days, 79.4% (27/34) in the subgaleal group and 57.3% (59/103) in the subdural group (P = .02) had been discharged home. Worse premorbid mRS (P = .002), subdural drain location (P = .004), and decreased consciousness at presentation (Glasgow Coma Scale<15) (P < .002) were independent predictors of a discharge destination other than home. At the 3-month follow-up, the subgaleal group exhibited a mean improvement of 0.77 ± 1.2 points, while the subdural group had a deterioration of 0.14 ± 0.8 points (P < .01). Subgaleal drain location (P < .0001), better preoperative Glasgow Coma Scale (P = .01), and worse premorbid mRS (P = .0003) were independent predictors of improved mRS at 3 months. Recurrence requiring repeat surgery were more common in the subdural (13.6% (14/103) than the subgaleal 2.9% (1/34) group, P = .12), although the absolute incidence rates remained low. CONCLUSION: In patients undergoing minicraniotomy for cSDH, subgaleal drains are associated with shorter hospitalization, greater chance of discharge home, and better functional outcomes than subdural drains.

RESUMO

BACKGROUND: Prolactinomas are common tumours that significantly reduce quality-of-life (QOL) due to sellar mass effect, secondary hypogonadism, and the peripheral effects of prolactin. Understanding the factors that influence QOL would provide insights into therapeutic targets to optimise patient outcomes and improve wellbeing in prolactinoma. METHODS: A systematic review was performed in accordance with the PRISMA statement. Studies that reported patient QoL using validated metrics were included. Bias and methodological rigour were assessed using the MINORS criteria. RESULTS: A total of 18 studies were identified studies were available for review, comprising 877 patients. Most were small cross-sectional studies at high risk of bias. Prolactinoma exhibit worse QOL than healthy controls, particularly mental and psychosocial wellbeing. QOL is also worse than patients with non-functional adenomas, but better than those with Cushing's disease and acromegaly. QOL correlates with prolactin levels, and approaches population baseline with prolonged biochemical control. Dopamine agonists and surgery both improve overall QOL, however improvements are more rapid with surgery. CONCLUSION: Poor quality of life in prolactinoma is multifactorial, related to biochemical control, side effects of therapy, and sellar mass effect. Targeting persistent symptoms, reducing healthcare costs, and reducing side-effects of therapy are avenues to improving QOL in patients with prolactinoma.

RESUMO

Foramen magnum meningiomas are challenging lesions owing to their proximity to the lower brainstem, vertebrobasilar system, and lower cranial nerves.1,2 Tumor size, origin, morphology, relationship to neurovascular structures, and bony anatomy determine the optimal surgical approach.2,3 Classically, far lateral approaches have been the workhorse approach to the foramen magnum. Variations of the far lateral including transcondylar and extended transcondylar (paracondylar), with or without transposition of the vertebral artery, are sometimes used for a more lateral approach to the brainstem and clivus. Here, we present a 60-year-old male patient presenting with a large foramen magnum meningioma. Preoperative workup includes computed tomography and MRI with angiography to assess for posterior circulation dominance, anatomic variants including posterior inferior cerebellar artery origin, venous, and bony anatomy.1,4 An extreme far lateral provides access anterior to the vertebral artery to extend exposure beyond the standard far lateral approach. This comprised transcondylar drilling, bony mobilization of the V3 Vertebral artery from C1 foramen transversarium, and dural mobilization of vertebral artery with a dural cuff at its site of dural entry. The patient tolerated the procedure, gross total resection was achieved, and the patient was discharged home. This video demonstrates in detail the steps of exposure, condylar drilling, vertebral artery transposition, and dural opening. These maneuvers can be difficult to conceptualize yet are key to successful extended transcondylar exposure. The patient gave informed consent for surgery and video recording. Institutional Review Board approval was deemed unnecessary.

RESUMO

OBJECTIVE AND STUDY DESIGN: This is a retrospective, descriptive study of consecutive patients undergoing novel preoperative pushable coil localization for spinal surgery, in order to evaluate its feasibility, safety and accuracy. METHODS: Consecutive patients who underwent pre-operative coil marking for spinal surgery at our institution from May 2018 to July 2021 were included. Data were collected for coil placement, accuracy, complications and fluoroscopy usage. Patient demographic and relevant perioperative and procedural data were also collected. RESULTS: A total of 34 patients were identified of which 32 (94%) had complete data and imaging at last clinical follow up, with a mean duration of 13.9 months. There were no incorrect level surgeries performed. There were no coil-related complications found in our cohort. CONCLUSIONS: Preoperative coil placement is an accurate, safe and well-tolerated method for level localization in spinal surgeries.
