A Direct Aspiration First Pass Technique is one of the most widely used techniques in mechanical thrombectomy. Aspiration catheter size plays a major role in the success of this technique. The AXS Vecta (Stryker Neurovascular, Fremont, California, USA) aspiration catheter is the first approved 0.071-inch catheter for mechanical thrombectomy. Here, we report our initial experience with direct aspiration thrombectomy using the AXS Vecta aspiration catheter. ⋯ In this early experience with the new AXS Vecta aspiration catheter, the catheter was safely navigated to the target vessel even at the level of M2 segment.

Serotonin syndrome (SS) is a common disease entity and could result in death if missed. The incidence of SS is underestimated due to misdiagnosis of many cases, especially the ones with less severe presentation. Many medications have been depicted as the source of SS. We present a case of SS in a patient who received intravenous tramadol and oral gabapentin as pain management after spine surgery. ⋯ Physicians treating spine patients should be alert about SS in patients using both tramadol and gabapentin.

Traumatic acute subdural hematomas (ASDHs) showed the highest mortality of intracranial hematomas. The aim of the current study was to identify predictive factors of poor prognosis among patients who were operated on. ⋯ The context of polytrauma, ASDH thickness, and age were major predictive factors of poor prognosis in patients with surgically evacuated traumatic ASDH. The CART algorithm using these features isolated subgroups with decreasingly unfavorable outcome, providing a relevant statistical tool to apply to future studies of traumatic ASDH.

Intracranial arteriovenous fistulas, rare causes of spontaneous intracerebral bleeding, are direct communications between an arterial feeder and an arterialized vein that drains a normal brain. Arteriovenous disconnection is the only effective treatment for this type of vascular malformation, which is often reached microsurgically due to the difficult endovascular access. Intraoperative indocyanine green videoangiography (ICG-VA) is a valuable help in identifying the arterialized draining vein and its direct communication with the arterial feeder and in confirming real-time interruption of the fistula. ⋯ Under intraoperative neurophysiologic monitoring the fistula was located with the aid of ICG-VA and interrupted (Video 1). Both control ICG-VA and postoperative angiogram confirmed resolution of the fistula. At a 3-month follow-up the patient had a complete neurologic recovery.

Temporalis muscle (TM) hollowing is a complication of cranioplasty which diminishes the aesthetical outcome of the surgery and results in suboptimal functional outcome. We present and compare a modified split-temporalis muscle elevated margin cranioplasty using 3-dimensional printed titanium implant with conventional 3-dimensional printed titanium implant cranioplasty to determine an effective treatment method. ⋯ The augmented cranioplasty leads to superior aesthetical outcome, and the quantitative analysis also supports the efficacy of augmented cranioplasty. The surgery is technically simpler than the conventional method, therefore lowering the risk of surgical complications. Therefore, we hope that the modified cranioplasty method will be considered as an effected cranioplasty method for preventing TM hollowing.
