Comparative Study
Minimally invasive transforaminal lumbar interbody fusion in multilevel; comparison with conventional transforaminal interbody fusion.
Minimally invasive (MIS) transforaminal lumbar interbody fusion (TLIF) has shown superior or noninferior results compared with conventional TLIF in single segments. There were no comparative studies between MIS and conventional TLIF in multisegments. The purpose of this study was to compare MIS and conventional TLIF in multisegments. ⋯ MIS TLIF and conventional TLIF showed similar clinical and radiologic outcomes. MIS TLIF may be a better choice for 2- or 3-segment lumbar fusion in perioperative outcomes.

Comparative Study
Stereotactic Radiosurgery for Partially Resected Cerebral Arteriovenous Malformations.
Incomplete microsurgical resection of cerebral arteriovenous malformations (AVM) occurs uncommonly. However, such patients harboring postoperative residual nidi remain exposed to the risk of AVM hemorrhage and are therefore reasonable candidates for further intervention. The goals of this retrospective case-control study are to analyze the radiosurgery outcomes for partially resected AVMs and determine the effect of prior resection on AVM radiosurgery outcomes. ⋯ Radiosurgery affords a reasonable risk-to-benefit profile for incompletely resected AVMs. For those with a small-volume residual nidus after resection, radiosurgery should be considered an effective alternative to repeat resection.

Few reports have been published discussing surgical outcomes of paraclinoid aneurysms using multifarious treatments such as high-flow bypass. ⋯ Surgical treatment of unruptured paraclinoid aneurysm has high efficacy with good outcomes and a high rate of complete exclusion. However, the rate of visual disturbance is relatively high. Careful surgical techniques and intraoperative monitoring are therefore required.

The relationship between preoperative functional findings, derived from functional magnetic resonance imaging and diffusion tensor imaging, and surgical outcomes in patients with motor cortical arteriovenous malformations (AVMs) has not been determined. The aim of this study was to determine the relationship between preoperative functional findings and surgical outcomes in patients with motor cortical AVM. ⋯ Nidus involving the CST and the level of the CST involved, rather than cortical reorganization, may be associated with surgical outcomes in patients with motor cortical AVM.
