En-bloc sacrectomy is the treatment of choice for patients affected by sacral chordoma. It is a radical surgical procedure, which has to face the problem of handling fragile anatomic structures, such as the internal iliac vessels and the sacral nerve roots, with the risk of causing bowel, bladder, and sexual dysfunction. The combined anterior-posterior approach allows for a safer dissection of the tumor from the mesorectal fascia than the mere posterior approach, especially for tumors extending proximally to S3. Robotic surgery can improve the safety of the procedure. Sacral nerve stimulation is an accepted therapeutic option for fecal incontinence and may be used to treat postoperative incontinence. ⋯ From our experience, a robotic anterior approach increases safety for the organs in the pelvis when performing a sacrectomy. Moreover, a sacral nerve stimulator should be considered to manage neurologic complications following transection of nerve roots after sacrectomy.

Although Thrombolysis in Cerebral Infarction (TICI) grade 2B or 3 is considered successful after endovascular thrombectomy (EVT) for acute ischemic stroke, TICI 2B was found to be associated with poorer outcomes than was 3. Furthermore, the newly proposed TICI 2C grade seems to be clinically equivalent to TICI 3 rather than to 2B. This network meta-analysis aimed to assess the differences in clinical outcomes between TICI grades and redefine successful reperfusion. ⋯ Patients with TICI 2C grade would be distinguished from those with 2B, because 2C is clinically equivalent to 3 and has a better outcome than 2B. Therefore, achieving 2C or 3 is likely to be closer to the successful aim of endovascular thrombectomy in acute ischemic stroke than achieving 2B.

To assess the current efficacy, safety, and risk factors of the Woven EndoBridge (WEB) in treating wide-neck intracranial aneurysms. ⋯ WEB is safe and shows promising efficacy in treating wide-neck intracranial aneurysms. We preliminarily identified several risk factors for short-term angiographic outcomes.

Assessment of transverse ligament (TL) competence in patients with suspected atlantoaxial instability is performed via indirect radiograph measurements or direct TL visualization on magnetic resonance imaging (MRI). Interpretation of these images can be limited by unique patient anatomy or imaging technique variability. We report a novel technique for evaluating TL competence using flexion-extension computed tomography (feCT) scan with 3-dimensional (3D) segmentation and quantitative analysis. ⋯ 3D segmentation and quantitative analysis of feCT scan allow objective indirect assessment of TL integrity. Results are consistent with MRI findings and offer additional biomechanical information regarding the direction and distribution of atlantoaxial motion.

Meta Analysis
Insulin in the Management of Acute Ischemic Stroke: A Systematic Review and Meta-Analysis.
The role of tight glycemic control in the management of acute ischemic stroke remains uncertain. Our goal is to evaluate the effects of tight glucose control with insulin therapy after acute ischemic stroke. ⋯ Tight glucose control after acute ischemic stroke is not associated with improvements in mortality, independence, or mRS score and leads to higher rates of symptomatic or severe hypoglycemia.
