Endoscopic Management of Lateral Ventricle Arachnoid Cysts - Case Series with Proposed Classification.
We present a case series of 7 patients with intraventricular arachnoid cysts of lateral ventricle managed with endoscopic treatment with proposed classification of the cyst based on anatomic extent. ⋯ Multiple endoscopic fenestrations for lateral ventricle arachnoid cyst according to its location and anatomic extension help to reduce recurrence and good outcome. Cyst excision is recommended only when the cyst wall is easily separable from the lateral ventricle wall. Intraoperative use of thulium light amplification by stimulated emission of radiation helps in achieving early hemostasis and easy perforation of the thick cyst wall.

To detect post-traumatic vasospasm in patients with traumatic brain injury (TBI), we implemented a simplified transcranial Doppler (TCD) surveillance protocol in a neurointensive care setting. In this study, we evaluate the yield of this protocol. ⋯ The implementation of a simplified TCD surveillance protocol in a neurointensive care setting yielded an 18% detection rate of TCD suspected vasospasm. In our cohort of patients with TBI, decompressive craniectomy was associated with increased risk of developing TCD suspected vasospasm.

We investigated the differences in motor symptom change outcomes after bilateral subthalamic nucleus (STN) and globus pallidus internus (GPi) deep brain stimulation (DBS) in well-defined motor subtypes of Parkinson's disease (PD) to improve clinical decision making. ⋯ Our results suggest that the different PD motor subtypes will have differential responses to STN-DBS and GPi-DBS, that TDT patients will experience greater improvement than ART patients, and that STN-DBS provides better effects for ART patients than does GPi-DBS. In addition, different motor symptoms among the different motor subtypes might respond differently to STN-DBS than to GPi-DBS. All these factors could reflect the heterogeneity of PD. Longer-term outcomes across the different motor subtypes and stimulation targets should be studied further.

We sought to compare the diagnostic accuracy of cephalic indices for type B basilar invagination (BI). ⋯ The HWI showed the largest area under the ROC curve in comparison with the WLI, with robust sensitivity and specificity values, indicating that the proportions between cranial height and width can help clinicians in investigating type B BI.

This study aims to report the clinical outcomes associated with the percutaneous intralaminar screw repair performed for pars defects in adults. ⋯ Minimally invasive repair of lumbar spondylolysis with percutaneous intralaminar screw fixation restores the motion segment and can provide early resumption of physical activity with minimal muscle damage, smaller skin incision, and less soft tissue dissection.
