Neurovascular hybrid operating rooms (h-OR) combine a conventional operating theatre with high-resolution digital subtraction angiography (DSA). We describe a one-step combined surgical and endovascular treatment in a h-OR for a paediatric internal carotid artery giant aneurysm that can be an optimal solution to manage challenging cases, such as giant aneurysms. Case Description An 11-year-old boy presented with rapid onset right hemiparesis and left eyelid ptosis. A three months history of headache associated with sporadic vomit was reported. A giant, unruptured, left internal carotid artery aneurysm (ICA) was detected on imaging. The patient underwent surgical trapping of the aneurysm. Intraoperative DSA showed residual backflow from the posterior communicating artery (PComA) and coils were placed to completely exclude the aneurysm. At 18 months follow up, the patient showed a complete recovery and MRI showed a progressive reduction of the sac aneurysm. Conclusions Due to their morphologic variability, intracranial giant aneurysms may require a different procedural strategy instead of direct clipping or coiling. The introduction of h-OR allows combined treatments to be performed simultaneously in the same room setting. The present case shows that combined treatment in a neurovascular h-OR can be an optimal solution to manage challenging cases, such as giant aneurysms, reducing operative time with the added benefit of selecting an appropriate strategy adjustment in a multidisciplinary effort.</p>","PeriodicalId":16544,"journal":{"name":"Journal of neurological surgery.

Altogether, neither are they sufficient to predict outcome or occurrence of events reliably nor do they offer a united front.

The molecular pathology results were summarized to evaluate the mechanism. Results One hundred forty-seven patients with metastasis in 113 papers published from 1928 to 2022 were included.

Screw placement via small incisions reduces the risk of wound healing disorders and blood loss, and patients can be mobilized more quickly and with less pain. In 2022, a cervical minimally invasive stabilization system became available for the complete percutaneous insertion of both cervical pedicle screws and rods. We report on the first results and experiences with this new technology. Methods In this retrospective case series, we included patients with cervical instability treated by minimally invasive percutaneous cervical und upper thoracic spine pedicle screw and rod insertion between August 2022 and August 2023. Intra- and postoperative complications as well as revision surgeries were recorded. The screw position was evaluated by three examiners in the postoperative CT using the Bredow classification. Results Our series includes six male patients (age=56.9±12.9 years; BMI=29.8±9.6 kg/m2). The indication for surgery was trauma, tumor and degenerative stenosis in two patients each. An excellent/good screw position (Bredow 1 and 2) was found in 84.4% of the screws (n = 27/32). None of the screws rated as Bredow 3 (n=2/32) or Bredow 4 (n=3/32) resulted in a neurological deficit or radicular pain and none had to be repositioned. No neurologic complication or revision surgery occurred. As a complication not directly related to the surgery technique, one patient died of a pulmonary lung embolism on the 7th postoperative day.

Aiming to guide approach selection, preoperative grading systems have been described. Method All cases of TSM treated from 2013 to 2018 by extended endoscopic endonasal (EEA) or SO approach have been reviewed and classified according to three preoperative grading system: McDermott scale, Optic Nerve Laterality Score and Yaşargil criteria. Results A total of 15 patients with TSM were treated with the EEA (n=6) or the SO (n=9) approach. Globally, gross total resection was obtained in 87% (n=13) of cases and was higher with the SO (100%, n=9) compared to the EEA (67%, n=4). Visual function improved in all but one patient (n=14). Compared to the EEA group, patients treated by the SO approach had larger tumors (32.3 mm vs 24.5 mm), higher rate of optic canal invasion (4/9 vs 0/6) and arterial encasement (6/9 vs 1/5). Patients with McDermott total point of 1-2 (7/15) were treated mainly by the EEA; all patients with McDermott total score ≥3 (8/15) were treated by the SO approach. All patients with optic canal invasion (4/15) and lateral extension of the tumor (ONL score = 1-3) were treated by the SO approach. Conclusions The SO and EEA are two minimally invasive approaches safe and effective for treating TSM. For tumors with lateral extension (optic nerve laterality score = 1-3), larger diameter (> 30-35 mm), vascular encasement or optic canal involvement (McDermott total point = 2-3), the SO craniotomy is preferred. For small and median tumors with no optic canal invasion or vascular encasement (McDermott total point = 1-2), the EEA represents a valid option.</p>","PeriodicalId":16544,"journal":{"name":"Journal of neurological surgery.
