Treatment modality for ruptured and unruptured intracranial aneurysms has shifted during the last two decades from microsurgical treatment towards endovascular treatment. We present how this transition happened in a large European neurovascular center.
A substantial proportion of patients undergoing surgery for chronic subdural hematoma (CSDH) use anticoagulation medication due to atrial fibrillation (AF). We assessed the risk postoperative thromboembolic and hemorrhagic complications in CSDH with a history AF their association outcome. This posthoc analysis nationwide multicenter randomized controlled trial conducted during 2020-2022 included preoperative AF. incidence associations functional outcomes mortality. Of 589 patients, 128...
BACKGROUND: Microsurgical resection of vestibular schwannoma (VS) is highly challenging, especially because surgical treatment nowadays mainly reserved for larger (Koos grade 3 and 4) tumors. OBJECTIVE: To assess the performance three-dimensional exoscope use in VS comparison with operative microscope. METHODS: Duration surgery clinical radiological results were collected 13 consecutive exoscopic surgeries. Results compared 26 preceding microsurgical resections after acknowledging similar...
Background: In recent years, three-dimensional exoscopes have been increasingly applied in neurosurgery. Multiple exoscopic systems are available, all offering specific features. this study, we assessed practical and visualization performance of four different a highly challenging microsurgical procedure, evaluated whether these affected the quality work. Methods: We included exoscopes: Olympus ORBEYE, Zeiss KINEVO, Storz VITOM, Aesculap AEOS. With each exoscope, ten experimental bypass...
Abstract Background The surgical 3D exoscopes have recently been introduced as an alternative to the microscopes in microneurosurgery. Since exoscope availability is still limited, it relevant know whether even a short-term training develops skills needed for performing exoscope-assisted surgeries. Methods Ten participants (six consultants, four residents) performed two laboratory bypass test tasks with (Aesculap Aeos®). Six sessions (6 h) were between (interval of 2–5 weeks) on artificial...
OBJECTIVE In contrast to high-grade dural arteriovenous fistula (dAVF), low-grade dAVF is mainly associated with tinnitus and carries a low risk of morbidity mortality. It remains unclear whether the benefits active interventions outweigh complications in dAVF. METHODS The authors conducted retrospective single-center study that included all consecutive patients diagnosed an intracranial (Cognard type I IIa) during 2012–2022 DSA. analyzed symptom relief, symptomatic angiographic cure,...
Background Despite recent multi-institutional efforts, long-term data on clinical and radiological outcomes after treatment of high-grade dural arteriovenous fistulas (dAVFs) remain scarce. This study aimed to evaluate the risk hemorrhage fistula-related mortality treatment. Methods Retrospective analysis all consecutive patients primarily diagnosed with a dAVF (Cognard grade 2b, 2a+b, 3, 4) between January 2012 September 2022 at large neurovascular center. Primary endpoints were...
Abstract Background and objective The main challenge of bypass surgery complex MCA aneurysms is not the selection type but initial decision-making how to exclude affected vessel segment from circulation. To this end, we have previously proposed a classification for based on preoperative angiography. current study aimed validate new assess its diagnostic reliability using giant aneurysm registry as an independent data set. Methods We reviewed pretreatment neuroimaging 51 patients with (>...
Abstract Purpose Superficial temporal artery to middle cerebral (STA-MCA) direct bypass surgery is the most common surgical procedure treat moyamoya disease (MMD). Here, we aim compare performance of 3D exoscope in with gold standard operative microscope. Methods All STA-MCA procedures performed at a single university hospital for MMD between 2015 and 2023 were considered inclusion. Data retrospectively collected from patient files video material. From 2020 onwards, exclusively using digital...
Alcohol consumption has been reported to deteriorate surgical performance both immediately after as well on the next day. We studied early effects of alcohol microsurgical manual dexterity in a laboratory setting.Six neurosurgeons or neurosurgical residents (all male) performed micro- and macro suturing tasks consuming variable amounts alcohol. Each participant drank 0-4 doses (14 g ethanol). After delay 60-157 min, he macrosurgical task (with microscope). The consisted cutting re-attaching...
BACKGROUND Dural arteriovenous fistulas (dAVF) may induce imaging findings attributable to various disease entities including malignant neoplasms. In these cases, diagnosis and adequate treatment are often delayed patients be exposed spurious treatments in addition the risks inherent an untreated dAVF with cortical venous drainage. OBSERVATIONS The authors report a case of patient referred for surgical supratentorial high-grade glioma. Thorough review data challenged initial radiological led...
