Subdural Versus Subgaleal Drain Placement After Minicraniotomy for Chronic Subdural Hematoma.

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.

Microsurgical disconnection of a T12/L1 ventral intradural perimedullary arteriovenous fistula (type IV) via instrumented trans-pedicular approach.

We present a case of microsurgical disconnection of a PMAVF supplied by the artery of Adamkiewicz with fistulation at the ventral spinal cord.

Recurrent haemorrhagic pontine cavernoma resection via a retrosigmoid microsurgical approach.

Background: Brainstem cavernomas occasionally require surgical treatment. Appropriate patient selection and thorough understanding of the anatomy and technical nuances involved in microsurgical resection is a pre-requisite in undertaking these challenging cases.

Case Description: We present a video case of a patient with a recurrent haemorrhagic pontine cavernoma.

Microsurgical clipping of ruptured supraclinoid internal carotid artery aneurysm with extradural clinoidectomy.

Background: Supraclinoid Internal Carotid Artery (ICA) aneurysms require additional access to standard pterional craniotomy via extradural clinoidectomy. Existing texts and surgical videos lack clarity, explanation and a clear step by step process.

Case Description: We present a case of a ruptured supraclinoid ICA aneurysm and extradural clinoidectomy along with 3D reconstructed imaging of the case anatomy to guide its resection.

The utility of internal spinal marking for intraoperative localisation: A systematic review.

Background: Incorrect level spinal surgery is an avoidable complication, with significant ramifications. Several pre-operative spinal marking techniques have been described to aid intraoperative localisation.

Methods: A systematic search of Ovid MEDLINE, and EMBASE was performed from inception to July 2022.

Cranial fat dissemination following fat grafting for lumbar dural tear: First case report in the literature.

Introduction And Importance: Dural tear and cerebrospinal fluid (CSF) leak is among the most common complications in lumbar spine surgery. Although primary dural suturing is the preferred method for repair, this is not always achievable specially with ventrolateral tears. Autologous fat grafting is one of the oldest and effective methods for dural repair which can also be used along with other methods of repair.

Predictive Relevance of Early Temperature Elevation on the Risk of Delayed Cerebral Ischemia Development Following Aneurysmal Subarachnoid Hemorrhage.

Background: Fever in aneurysmal subarachnoid hemorrhage (aSAH) has been associated with delayed cerebral ischemia (DCI), but its relevance in risk stratification has not been explored. This study investigated whether early temperature elevation following aSAH predicts impending clinical deterioration caused by DCI.

Methods: Relevant cases were identified from a prospectively maintained database for consecutive patients with aSAH treated at our center between July 2015 and January 2020.

Bleeding from the pancreatic cut surface post pancreaticoduodenectomy: a review of a tertiary referral centre.

Background: Haemorrhage from the pancreatic cut surface after pancreaticoduodenectomy is uncommon. The optimal treatment for post-pancreatectomy haemorrhage (PPH) from the pancreatic cut surface remains controversial.

Methods: We performed a retrospective analysis including all patients who underwent a pancreatiocoduodenectomy between 2008 and 2018 at a single tertiary institution in Melbourne, Australia, to analyse the incidence, potential risk factors, treatment and outcomes of cut surface PPH.

The Role of Laparoscopic Cholecystectomy After Severe and/or Necrotic Pancreatitis in the Setting of Modern Minimally Invasive Management of Pancreatic Necrosis.

Objectives: The trend toward minimally invasive procedures (MIP) in necrotizing pancreatitis is increasing. The optimal timing and technique of cholecystectomy in severe/necrotizing pancreatitis is unclear. This study aims to determine the role of laparoscopic cholecystectomy after severe/necrotizing pancreatitis in the context of MIP.

Sex differences in aneurysmal subarachnoid haemorrhage (aSAH): aneurysm characteristics, neurological complications, and outcome.

Background: Women are over-represented in aSAH cohorts, but whether their outcomes differ to men remains unclear. We examined if sex differences in neurological complications and aneurysm characteristics contributed to aSAH outcomes.

Methods: In a retrospective cohort (2010-2016) of all aSAH cases across two hospital networks in Australia, information on severity, aneurysm characteristics and neurological complications (rebleed before/after treatment, postoperative stroke < 48 h, neurological infections, hydrocephalus, seizures, delayed cerebral ischemia [DCI], cerebral infarction) were extracted.

Spinal Pleomorphic Xanthoastrocytoma: Case Report and Literature Review.

Pleomorphic xanthoastrocytoma (PXA) is an uncommon central nervous system neoplasm with an overall favorable survival prognosis. Metastatic spread of PXA to the spinal cord and the cauda equina is rare and may have a different clinicopathologic course. Treatment and prognostic outcomes, in this context, are not well defined.

Glioblastoma Presenting as Spontaneous Subarachnoid Hemorrhage: Technical Case Note of Combined Endovascular and Microsurgical Vision-Sparing Treatment.

Background: Clinical utility of endovascular adjunct for tumor resection is well established, but its role in acute subarachnoid hemorrhage secondary to neoplastic pseudoaneurysm rupture has not been reported.

Case Description: We discuss a 46-year-old patient presenting with a World Federation of Neurological Surgeons grade 1 subarachnoid hemorrhage from a ruptured posterior cerebral artery pseudoaneurysm due to glioblastoma tumor invasion.

Conclusions: A combined targeted endovascular embolization with microsurgical resection to spare the calcarine artery was used to avoid disruption to the optic radiation fiber pathway.

Primary intradural extramedullary Ewing sarcoma of the cervical spine: A case report and review of the literature.

Spinal intradural Ewing sarcoma (ES) of the cervical region is not common. Few cases have been reported and optimal management remain poorly defined. We described a case of a young woman with extensive primary leptomeningeal spinal ES and conducted a review of the literature.

Buccal space tumours.

Objective: To review the available literature as it pertains to the buccal space with a specific focus on the pathologies encountered within this space. Clinical presentation, investigations, and surgical approaches to the region are also reviewed.

Methods: A systematic review of the available literature was performed on buccal space tumours from 1980 to 2017.
