Variability, with no general consensus, exists in how patients' blood pressure should be managed after successful mechanical thrombectomy (MT) for large vessel ischemic stroke. We examined whether exceeding the systolic blood pressure (SBP) targets in patients during the first 24 hours after successful MT led to worse outcomes. ⋯ These results suggest that individual instances of SBP elevation alone after successful MT, rather than a necessarily prolonged increased blood pressure as reflected by the mean or median SBP values, can significantly affect the clinical outcomes after successful MT.

Primary fourth ventricle outlet obstruction (PFVOO) is a rare cause of hydrocephalus with an unclear etiopathogenesis, and thus, consensus regarding the recommended treatment protocol is lacking. This study aims to summarize current knowledge of this condition in the light of our own treatment experience. ⋯ Despite the fact that PFVOO can be defined as an obstructive hydrocephalus, there seems to be a higher risk of ETV failure in such cases. The alternative treatment modalities presented are still recommended. Confirmation of these findings requires a larger multicenter study.

Sex Differences in Postoperative Complications and Functional Status After Deformity Correction Surgery: Do Men Fare Better Than Women?
We investigated whether a sex-related difference exists in the postoperative complication risk and health-related quality of life measures after surgery for adult spinal deformity. ⋯ In the present study, after adjustment for important baseline prognostic factors, no differences were found in the postoperative complication rates or extent of functional improvement when stratified by sex. Both sexes responded equally well to corrective surgery for symptomatic adult spinal deformity.

This is a single-surgeon series to prospectively evaluate the clinical and radiologic results of sacroiliac joint (SIJ) stabilization using hydroxyapatite (HA)-coated, fully threaded screws in patients with SIJ dysfunction. ⋯ Percutaneous SIJ fixation procedure has been shown to have good clinical outcomes, but the use of HA-coated fully threaded screws in this procedure is not recommended on the basis of patient-reported outcome measures and radiologic findings in this prospective study.

Putting 'CSF-shift' edema hypothesis to test: Comparing cisternal and parenchymal pressures after basal cisternostomy for head injury.
Increased brain edema in head injury is due to shift of cerebrospinal fluid (CSF) from cisterns at high pressure to brain parenchyma at low pressure. By opening basal cisterns and decreasing the increased cisternal pressure, basal cisternostomy (BC) results in reversal of CSF shift from parenchyma to cisterns, leading to decreased brain edema. Though the CSF-shift edema hypothesis is based on pressure difference between cisterns and brain parenchyma, the relationship of these pressures has not been studied. ⋯ Our study supports the CSF-shift edema hypothesis. Following DHC-BC, cisternal pressure is lowered to near-atmospheric pressure, and its relationship to parenchymal pressure predicts the future course of patients by reversal or re-reversal of CSF shift.
