Vasospasm following an aneurysmal subarachnoid hemorrhage (SAH) causes serious neurological complications, despite surgical clipping of the aneurysm. Intrathecal urokinase (UK) infusion has been shown to effectively prevent symptomatic vasospasm in patients who have undergone endovascular obliteration of the ruptured aneurysms. ⋯ Clearance of SAH via intrathecal UK infusion significantly reduced symptomatic vasospasm in patients in both UK groups, resulting in better clinical outcomes.

Lumbar instability and endplate defects are commonly seen in patients with spondylolisthesis. However, little is known about associations between segmental stability and endplate defects. The present study explored associations between stability-related radiographic parameters and endplate defect scores and assessed whether endplate defect scores can predict lumbar stability in lumbar spondylolisthesis. ⋯ Endplate defect scores increase with a reduction in IDH, progression of slippage and a decrease in ST in isthmic spondylolisthesis but not in degenerative spondylolisthesis. ST instability was associated with endplate defect scores in isthmic spondylolisthesis, and endplate defect scores could be used to reflect lumbar stability at the slippage segment.

Determination of the ventricle size in idiopathic normal pressure hydrocephalus (iNPH) is essential for diagnosis and follow-up of shunt results. Fully automated segmentation methods are anticipated to optimize the accuracy and time efficiency of ventricular volume measurements. We evaluated the accuracy of preoperative and postoperative ventricular volume measurements in iNPH by a magnetic resonance imaging (MRI)-based licensed software for fully automated quantitative assessment. ⋯ A fully automated volumetric method permits reliable evaluation of preoperative ventriculomegaly and postoperative ventricular volume change in idiopathic normal pressure hydrocephalus.

Impact of endoscopic surgery versus robot CAS-R-2 assisted with stereotactic drainage on prognosis of basal ganglia hypertensive intracerebral hemorrhage.
To evaluate the impact of endoscopic surgery (ES) versus robot CAS-R-2 assisted with stereotactic drainage on prognosis of basal ganglia hypertensive intracerebral hemorrhage (HICH). ⋯ Compared with robot CAS-R-2 assisted with stereotactic drainage, ES might have higher rate of good prognosis at 6-month follow-up for basal ganglia HICH.

Brain tumors display significant inter and intratumoral heterogeneity, impacting disease progression and outcomes. Preserving surgically resected tissue is vital for ensuring accurate research results to enhance understanding of tumor pathophysiology. This study evaluates tissue integrity and viability of tissue resected using 2 surgical devices for tumor resection: a mechanical microdebrider (MD) and an ultrasonic aspirator (UA). ⋯ Surgical handheld devices provide valuable, high-quality tissue samples for research. Surgeon preference, tumor pathology, and anatomical location dictate device choice. Both MD and UA devices are reliable for obtaining quality tissue specimens, facilitating translational neuro-oncology research.
