Advancing age and greater number of medical comorbidities are well-known risk factors for higher rates of surgical complications and undesirable outcomes. We sought to determine the risk of increasing medical comorbidities on surgical outcomes for patients with Parkinson disease undergoing deep brain stimulation (DBS) surgery. ⋯ Our findings indicate that DBS is efficacious in patients with multiple medical comorbidities. However, patients with ≥1 medical comorbidities may be more likely to have complications. The most common observed complication was wound infection. Patients with medical comorbidities may still benefit significantly from DBS when performed at experienced centers.

Controversy remains regarding the optimal methods for resection of the vertebral body, reconstruction of the anterior column, and decompression of the spinal cord in patients who have severe vertebral body destruction of the thoracic or lumbar spine with associated neurologic impairment. We report an alternative technique for primary treatment and salvage involving single-stage corpectomy followed by reconstruction of the anterior column using double small mesh cages via the posterior-only approach. ⋯ Single-stage corpectomy followed by reconstruction of the anterior column using double small mesh cages via the posterior-only approach is a reliable and less invasive single-stage treatment and salvage option in selected cases.

Large or giant thrombosed intracranial aneurysms (LGTIAs) are highly associated with poor prognosis and remain a challenging disease to treat by either surgery or endovascular treatment (EVT). EVT is considered more difficult for complicated aneurysm like LGTIAs. To understand long-term clinical and angiographic outcomes of EVT for LGTIAs, we retrospectively analyzed our single-center data on multimodality EVT for patients with LGTIAs. ⋯ Multimodality EVT for LGTIAs was performed with similar clinical outcomes and better radiologic outcomes compared with previous reports. New innovative techniques and devices are expected to be helpful for long-term aneurysm occlusion.

To assess the safety and efficacy of patient-specific three-dimensional (3D) rapid-prototype printing technology for pedicle screw insertion in patients with adolescent idiopathic scoliosis (AIS). ⋯ This is one of the initial reports to note the novel design and implementation of patient-specific 3D pedicle screw guides for adolescent idiopathic scoliosis surgery. Our pilot study shows that the use of these low-cost personalized 3D guides is completely safe and effective in both convex and concave sides of the curves.

Space-occupying cerebellar ischemic strokes (SOCSs) often lead to neurological deterioration and require surgical intervention to release pressure from the posterior fossa. Current guidelines recommend suboccipital decompressive craniectomy (SDC) with dural expansion when medical therapy is not sufficient. However, no good-quality evidence is available to support this surgical practice, and the surgical timing and technique both remain controversial. We have described an alternative to SDC, surgical evacuation of infarcted tissue (necrosectomy) and its clinical outcomes. ⋯ Necrosectomy appears to be a suitable alternative to SDC for SOCS, achieving comparable mortality and functional outcomes. Further trials are necessary to evaluate which surgical technique is more beneficial in the setting of SOCSs.
