Although sagittal spinal balance plays an important role in spinal deformity surgery, its role in decompression surgery for lumbar canal stenosis is not well understood. To investigate the hypothesis that sagittal spinal balance also plays a role in decompression surgery for lumbar canal stenosis, a prospective cohort study analyzing the correlation between preoperative lumbar lordosis and outcome was performed. ⋯ This study showed that preoperative lumbar lordosis significantly influences the outcome of decompression surgery on lumbar canal stenosis.

Ultra-early surgical clot removal relieves mechanical compression on adjacent normal brain tissue and limits the toxic effects of a hematoma, which might improve the outcomes in patients with intracerebral hemorrhage (ICH); however, hematoma expansion frequently occurs within 20 hours after the ictus, and this limits the use of ultra-early surgery. Computed tomography angiography spot sign was recently validated as an important predictor of hematoma expansion in patients with ICH. ⋯ Ultra-early stereotactic aspiration might decrease the volume of perihematoma edema and improve the functional outcomes to some extent, without increasing the recurrence of ICH and patient fatalities. Our findings suggest that using negative spot sign as an indicator for performing ultra-early stereotactic aspiration could be a safe and effective protocol for ICH patients.

Contact aspiration has gained growing acceptance in endovascular stroke therapy. The safety and efficacy data of the novel ARC catheter (Medtronic, Irvine, California, USA) used for intracranial thrombectomy have been poorly evaluated thus far. We report our preliminary results with the ARC with regard to angiographic reperfusion, duration of thrombectomy, safety, and clinical outcome at 90 days. ⋯ In our initial experience, the ARC appears safe and efficient for contact aspiration thrombectomy in large-vessel stroke therapy. However, improvement of its distal navigability needs further development to improve the success of aspiration alone, and large prospective studies are warranted.

A retrospective study. ⋯ We concluded that sex and American Society of Anesthesiologists physical status classification were independent risk factors of HBL in anterior cervical fusion surgery. In addition, there was a high proportion of HBL in anterior cervical fusion. When considering the strategies of transfusion, we should pay attention to the risk factors for HBL.
