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.

Epilepsy surgery has an important role in the treatment of patients with medically intractable seizures. Various authors have proposed an endoscopic technique to perform disconnective procedures. A detailed description of intracerebral anatomy seen through an endoscopic transcallosal corridor has not been reported. The aim of this study was to present a cadaveric step-by-step anatomical demonstration of endoscopic transcallosal hemispherotomy using a dedicated three-dimensional model. ⋯ This anatomical study described the relevant neurovascular structures to enable prediction of feasibility and control of the surgical procedure using the endoscopic transcallosal approach. The quantitative analysis permitted estimation of the theoretical efficacy of the procedure, confirming its relevant role in disconnective surgery.

The objective of the study was to determine home program matching percentage (staying in a program affiliated with one's medical school) for each neurosurgical residency program in the United States. Secondarily, it was to elucidate both program-level and resident characteristics associated with home program matching. ⋯ The results of this study delineate home program matching patterns on a program-by-program level for U.S. neurosurgical residency programs.

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.

Cranioplasty can be performed with either autologous or synthetic materials. No clear consensus has been reached regarding which material is superior and which social factors might influence the choice of treatment modality and the outcomes. We investigated the effects of race and socioeconomic status on the implant choice and outcomes. ⋯ We found increased autologous cranioplasty usage for non-White and Medicaid patients and increased use of higher cost synthetic implants for high-income patients. Non-White patients and those from higher income quartiles incurred higher admission costs. Medicaid patients had a longer LOS and decreased rates of home discharge.
