Microwave ablation (MWA) is a novel technique that offers several potential advantages over existing ablation systems, which include production of larger ablation zones, shorter procedural times, and more effective heating through high impedance tissues such as bone. ⋯ This review showed that MWA can be effective in achieving analgesia for up to 6 months in select cases, although most procedures were performed in combination with augmentation and/or open surgery. Local tumor control was additionally successful in most patients, suggestive of a potential curative role for MWA.

The cause of surfer myelopathy remains enigmatic and long-term follow-up outcomes are not well documented. In the present study, the mechanisms underlying surfer myelopathy in children are analyzed and the long-term follow-up outcomes are reported. ⋯ Surfer myelopathy in children is caused by spinal venous hypertension. The AIS grade on admission is a predictor of prognosis.

Although operative indications for traumatic brain injury (TBI) are known, neurosurgeons are unsure whether to remove the bone flap after mass lesion extraction, and an efficient scoring system for predicting which patients should undergo decompressive craniectomy (DC) does not exist. ⋯ These preliminary data showed that primary DC may benefit some patients with severe TBI with mass lesions. In addition, unresponsive preoperative pupil reaction and closed basal cistern could predict the DC decision.

Penetrating Vertebral Artery Injuries: A Literature Review and Proposed Treatment Algorithm.
Penetrating vertebral artery injuries (VAIs) are rare but devastating trauma for which the approach to treatment varies greatly. The literature on treatment modalities is limited to case reports, case series, and 1 review, with the majority of cases being treated surgically. However, with the advent of digital subtraction angiography, treatment has shifted toward less invasive endovascular modalities that allows one to assess the flow and risks of sacrificing the vertebral artery (VA). ⋯ This systematic review not only details the updated treatment options but also provides a decision algorithm for the treatment of penetrating VAI. It highlights the shifting treatment options of penetrating VAI to endovascular therapy, as well as details VAI variants that may suggest stenting over embolization.
