Da Vinci Robotic Assistance for Anterolateral Lumbar Arthrodesis: Results of a French Multicentric Study.

Background: The da Vinci robot (DVR) is the most widely used robot in abdominal, urological, and gynecological surgery. Due to its minimally invasive approach, the DVR has demonstrated its effectiveness and improved safety in these different disciplines. The aim of our study was to report its use in an anterior approach of complex lumbar surgery.

A Prospective, Multicenter, Observational Study of Surgical vs Nonsurgical Management for Pituitary Apoplexy.

Context: Pituitary apoplexy (PA) has been traditionally considered a neurosurgical emergency, yet retrospective single-institution studies suggest similar outcomes among patients managed medically.

Objective: We established a multicenter, international prospective registry to compare presentation and outcomes in PA patients treated with surgery or medical management alone.

Methods: A centralized database captured demographics, comorbidities, clinical presentation, visual findings, hormonal status, and imaging features at admission.

Comparative Evaluation of Two SD-OCT Macular Parameters (GCC, GCL) and RNFL in Chiasmal Compression.

Purpose: To evaluate the relationship between different macular thickness parameters analyzed by SD-OCT and the central visual field (VF) evaluated with automated kinetic perimetry in a cohort of patients with pituitary tumors.

Methods: Data from patients with pituitary adenoma treated at Reims University Hospital between October 1st, 2017, and May 31st, 2018 were collected. All patients underwent an automated kinetic perimetry and a SD-OCT to map the ganglion cell complex (GCC), the ganglion cell layer (GCL) thickness and the retinal nerve fiber layer (RNFL) using devices from two different manufacturers.

Gonadotropin-Secreting Pituitary Macroadenoma Complicated With Hemorrhagic Apoplexy in 18F-FDG PET/CT.

We report the case of 69-year-old man referred for a stage IV pulmonary adenocarcinoma and presenting a decrease in visual acuity. An 18F-FDG PET/CT showed an intense and heterogeneous uptake of a mass in the sellar region. An MRI showed a pituitary macroadenoma associated with a large cyst on the left side, with necrosis zones and fluid level, compressing the optic chiasma.

Surgery versus conservative care for Rathke's cleft cyst.

Background: Rathke's cleft cysts are benign cystic lesions of the sellar region, which may cause headache, pituitary deficiencies and visual disturbances from mass effect. Their management is not standardized yet. This study is about establishing a consensus for medical care of RCC.

Surgical treatment of high-grade spondylolisthesis: Technique and results.

Background: Surgical management of high-grade spondylolisthesis is not only challenging but also controversial, from in situ fusion to complete reduction. We report our results of a safe three-stage spinal procedure in a single surgical session with seven patients diagnosed high-grade spondylolisthesis.

Hypothesis: Posterior fixation combined with interbody fusion is effective on reduction, ossification and clinical outcomes in high-grade spondylolisthesis.

Evolution of macroprolactinomas during pregnancy: A cohort study of 85 pregnancies.

Objective: Pregnancy in patients with macroprolactinomas has been associated with a higher risk of pituitary tumour growth. However, the incidence and risk factors remain unclear. We aimed to evaluate the evolution of macroprolactinomas during pregnancy and to identify potential risk factors.

Clipping of recanalized intracerebral aneurysms initially treated by the Woven EndoBridge device.

Background And Purpose: Intrasaccular flow disruption using the Woven EndoBridge (WEB) is a safe and effective method to treat intracranial aneurysms, particularly wide neck bifurcation aneurysms. However mid term and long term follow-up imaging can show aneurysm remnant or recanalization, and retreatment is therefore sometimes necessary. In most cases, retreatment is performed using an endovascular approach.

Anterior skull base reconstruction after tumour resection using the posterior wall of the frontal sinus.

Introduction: The authors describe their experience of surgical closure of the anterior skull base after tumour resection, using the posterior wall of the frontal sinus.

Material And Method: The authors describe their anterior skull base closure technique performed in three patients after tumour resection. Tumour resection via a transglabellar approach resulted in an anterior skull base defect.

Comparison of two preventive dual antiplatelet regimens for unruptured intracranial aneurysm embolization with flow diverter/disrupter: A matched-cohort study comparing clopidogrel with ticagrelor.

Purpose: Standard dual antiplatelet therapy (DAPT) for complex aneurysms treated with flow diversion and flow disruption is acetylsalicylic acid (ASA) plus clopidogrel. However, clopidogrel resistance frequently occurs and can lead to thromboembolic events. Ticagrelor is an alternative not requiring platelet inhibition testing.

Reconstruction of cranioplasty using medpor porouspolyethylene implant.

Introduction: We describe our experience of cranioplasty after a calvarial defect, following an external decompressive craniectomy, with the Medpor (Stryker) porous polyethylene implant for cosmetic cranioplasty and reconstruction.

Methods: A retrospective chart review was performed on 23 consecutive patients who underwent cranioplasty at a single institution between January 2013 and January 2016: 9 patients after head injury and 14 patients after vascular event (ruptured aneurysm, intraprenchymal haematoma, malignant cerebrovascular accident). All patients with cranioplasties after oncological resection or infection were excluded.

Pituitary apoplexy and rivaroxaban.

Pituitary apoplexy (PA), defined by the occurrence of a massive hemorrhagic necrotic rearrangement within a pituitary adenoma, is rare. Its occurrence can be associated with certain risk factors, including anticoagulation. We report the first case of PA with rivaroxaban which is one of the new oral anticoagulants: a 73 year-old patient presenting with severe headache and visual field deterioration.

Ectopic bone formation with joint impingement after posterior lumbar fusion with rhBMP-2.

Recombinant human bone morphogenetic protein-2 (rhBMP-2) was recently licensed for local administration during posterior lumbar fusion. In this indication, considerable uncertainty remains about the nature and mechanisms of the many adverse effects of rhBMP-2, such as ectopic bone formation. We report a case of ectopic bone formation with impingement on a facet joint and incapacitating low back pain after minimally invasive transforaminal L5-S1 interbody fusion with local application of rhBMP-2 (InductOs(®)).

Cavernous sinus thrombosis secondary to aspergillus granuloma: A case report and review of the literature.

Cavernous sinus thrombosis is a rare but serious complication of sphenoid aspergillosis. The rarity of this pathology makes its diagnostic very difficult on a clinical, biological and radiological sense. The authors present a case of cavernous sinus thrombosis with ipsilateral internal carotid artery thrombosis secondary to a non-invasive sphenoid aspergillosis in an immunocompetent host, responsible of a cavernous syndrome associated to a Claude Bernard Horner syndrome.

Spontaneous epidural hematoma due to cervico-thoracic angiolipoma.

Epidural angiolipomas are uncommon benign tumors of the spine. Their clinical presentation is usually a progressive spinal cord compression. We report the case of a 22-year-old patient who presented with an acute paraparesis and a spontaneous epidural hematoma, which revealed a epidural angiolipoma which extended from C7 to T3.

Long-term results of carmustine wafer implantation for newly diagnosed glioblastomas: a controlled propensity-matched analysis of a French multicenter cohort.

Background: The standard of care for newly diagnosed glioblastoma is maximal safe surgical resection, followed by chemoradiation therapy. We assessed carmustine wafer implantation efficacy and safety when used in combination with standard care.

Methods: Included were adult patients with (n = 354, implantation group) and without (n = 433, standard group) carmustine wafer implantation during first surgical resection followed by chemoradiation standard protocol.

Long-term results of fractionated stereotactic radiotherapy as third-line treatment in acromegaly.

The treatment of acromegaly is based on surgery, drugs, and radiotherapy as a third-line option. Fractionated stereotactic radiotherapy (FSRT) is a new technique with a need for long-term evaluation. The purpose of the study was to evaluate long-term results of FSRT in acromegaly.

Advantages and limitations of endoscopic endonasal odontoidectomy. A series of nine cases.

Introduction: Transoral odontoidectomy is the treatment of choice in cases of anterior bulbo-medullary compression. The development of endoscopic procedures has made it possible to perform odontoidectomy via a minimally invasive endoscopic endonasal approach. We discuss the feasibility, advantages, and limitations of this surgical approach.

Prognostic value of retinal nerve fiber layer thickness for postoperative peripheral visual field recovery in optic chiasm compression.

Unlabelled: OBJECT.: The authors' objective was to evaluate the predictive value of preoperative axonal loss for peripheral visual field recovery after surgery for optic chiasm compression.

Methods: Consecutive patients with optic chiasm compression in the period from October 2010 through August 2012 were retrospectively studied.

[Facial nerve outcome after vestibular schwannoma surgery: About 89 patients].

Objectives: We evaluated the postoperative facial nerve function after vestibular schwannoma (VS) surgery and analyzed factors causing it.

Material And Methods: We included 89 consecutive patients undergoing surgical excision of unilateral VS. Patient and tumor characteristics, surgical approaches, facial nerve function, extent of tumor resection and complications were analyzed.

Evaluation of the clinical usefulness for using verification images during frameless radiosurgery.

Our previous studies showed that intrafraction motion needs to be corrected for in frameless radiosurgery. This study was designed to evaluate if verification images can correct for mechanical inaccuracy and intrafraction motion. With proper immobilization and verification images on a regular basis during treatment, mechanical (table-) inaccuracies and intrafraction motion can be corrected for and the absence of PTV-margins warranted.

Anterior minimally invasive extrapleural retroperitoneal approach to the thoraco-lumbar junction of the spine.

Background: The anterior approach to the thoraco-lumbar junction of the spine allows therapeutic interventions on post-traumatic, infectious, and neoplastic vertebral lesions from T11 to L2 combining spinal cord decompression, corporectomy, and vertebral body fusion. However, this approach also has a reputation for damaging the intervening anatomic structures (lungs, peritoneum, and diaphragm). The objective of this study was to show that both nervous structure decompression and anterior vertebral reconstruction can be achieved via an anterior minimally invasive extrapleural retroperitoneal (AMIER) approach.
