Catastrophic epilepsy results in severe neurodevelopmental delay in infants because of frequent and/or long seizures. Therefore, consideration of early epilepsy surgery is essential for neurodevelopmental outcome. Once an infant with catastrophic seizures is identified as a surgical candidate, it is important that the surgical plan be carefully defined based on detailed presurgical evidence to minimize surgical complications in this age group. ⋯ Careful consideration of the noninvasive presurgical workup can identify focal onset even in the presence of catastrophic epilepsy with widespread bilateral abnormalities. Single-stage lobar leucotomy for disconnection of the epileptogenic zone can lead to excellent outcome in these patients.

Comparative Study
Minimally Invasive Transforaminal Versus Direct Lateral Lumbar Interbody Fusion: Effect on Return to Work, Narcotic Use, and Quality of life.
Direct lateral (DLIF) and transforaminal (TLIF) lumbar interbody fusions have been shown to produce satisfactory clinical outcomes with significant reduction in pain and functional disability. Despite their increasing use in complex spinal deformity surgeries, there is a paucity of data comparing outcome measures, which this study addresses. ⋯ Both MIS TLIF and DLIF provide long-term improvement in pain andfunctional outcomes, with an overall reduction in postoperative narcotic requirement. However, there was a significantly longer time to return to work and a greater incidence of reoperation in the TLIF cohort compared with the patients who underwent DLIF.

One of the most challenging aspects of the surgical treatment of tuberculum sellae meningioma is to control the involvement of the inferomedial side of the optic nerve, which is not directly visualized by an ipsilateral approach and thus requires optic nerve mobilization. ⋯ This approach allowed lower mobilization of the compromised optic nerve, better preservation of the vascularization of the visual pathways, and direct access to the inferomedial side of the optic nerve.

Internal carotid artery (ICA) occlusion associated with posterior cerebral artery (PCA) aneurysms is regarded as a rare cerebrovascular disease. Common treatment of aneurysms-direct clipping or coiling-is not taken into consideration for this kind of cerebrovascular property. Combined surgical cerebrovascular reconstruction of the superficial temporal artery-to-middle cerebral artery (STA-MCA) bypass offers a chance to downregulate the hemodynamic stress of aneurysm rupture. ⋯ Owing to ICA occlusion, the gap of hemodynamic stress between the posterior segment of the circle of Willis and anterior segment of the circle of Willis enlarged. This may lead to a ruptured PCA aneurysm. In this case, the aneurysm disappeared following an STA-MCA bypass. STA-MCA bypass may be one of the major reasons downregulating the gap, which can be regarded as an effective option concerning such aneurysms.

Preoperative embolization may facilitate skull base meningioma resection, but its safety and efficacy in the Onyx era have not been investigated. In this retrospective cohort study, we evaluated the outcomes of preoperative embolization of skull base meningiomas using Onyx as the primary embolysate. ⋯ For appropriately selected skull base meningiomas supplied by dura mater-based arterial pedicles without distal cranial nerve supply, preoperative embolization with current embolysate technology affords substantial tumor devascularization with a low complication rate.
