from the neocortex, to remove selectively only meso- and allocortical structures. Preliminary experience with SA performed using the PST approach had been already presented by Türe et al. in their work from 2012. 32 Issues regarding safety and reproducibility of the procedure have been raised by several authors (see Kaye in the comment to Kadri et al., 15 or Erdem 7 ). The PST approach for SA was introduced by the senior author (N.K.) at our institution in 2015 and has recently become our standard. The purpose of this study is thus to present our surgical results

D eep brain stimulation was first introduced in 1987 by Benabid et al. 4 targeting the VIM of the thalamus to treat PD. Since that time, DBS has largely replaced ablative procedures for the treatment of hyperkinetic movement disorders including PD, 4 , 11 , 25 , 37 ET, 3 , 21 , 23 , 33 dystonia, 10 , 26 , 41 , 42 cerebellar outflow tremor, 6 , 7 , 19 , 38 and Tourette syndrome. 12 , 20 , 39 The dramatic shift in the surgical management of movement disorders has brought with it concerns regarding the safety of DBS surgery 5 , 17 , 30 and hardware

, 10 Randomized controlled studies by Clark et al. 4 and Wardlaw et al., 20 as well as multiple retrospective reviews and prospective trials by others, 5–9 , 11–14 , 19 have found that, compared with placebo or conservative medical management, vertebroplasty and kyphoplasty can safely increase vertebral body height, decrease pain, and increase activity levels and improve quality of life in patients with osteoporotic or metastatic compression fractures. To our knowledge, this is the first study to have addressed the safety of performing kyphoplasty at 4 or more

brain targets using electric current. DBS electrodes are connected to an implantable pulse generator (IPG) via extension wires that are tunneled under the skin. The IPG is typically placed subcutaneously in the upper chest wall. Because of safety concerns and stringent vendor guidelines, MRI of patients following DBS implantation is highly restricted. 7 , 12 , 20 , 33 Prior studies have investigated the safety of brain MRI in these patients, 6 , 7 , 13 , 26 but safety data for MRI of other body parts, such as the spine, are lacking. Due to 3 previous cases of DBS

with DBS for PD between 2002 and 2009. Safety outcomes, on the other hand, have remained essentially stable over time. Overall, 87% of patients were discharged routinely. Of the “non-routine” discharges, 5.39% involved the need for home health care, 7.22% involved discharge to a skilled nursing facility or other long-term care facility, and in 0.28% of the cases, the patients died. The percentage of non-home discharges (that is, discharges classified neither as “routine” nor to home health care) did not change significantly over the 8-year period (r = −0.57, p

battery generates electric pulses, analogous to a cardiac pacemaker. In addition to being essential to clinical care, MRI can play a significant role in understanding how DBS modulates brain circuitry. 22 MRI scanning of hardware implants such as a DBS neuromodulation system, however, is subject to stringent safety guidelines restricting its use. 19 Due to 2 reported cases of DBS patient injuries presumed to be MRI-related, MRI guidelines have become restrictive and vendor specific. 11 The Medtronic, Inc., neuromodulation system is the most commonly used. It has been

, increasing the overall incidence of screw revision. Our initial 2.5-year experience did not show a decreased rate of reoperation compared with the free-hand pedicle screw placement technique with postoperative CT imaging. Future studies with larger patient populations will be needed to demonstrate more concretely the effectiveness of intraoperative CT scanning in enhancing patient safety during pedicle screw placement.

unit. Early discharges are particularly critical for surgical services to optimize patient flow from the operating room to the intensive care unit or the perianesthesia care unit, and such improvements in efficiency enhance bed availability for the hospital. Each appointment was scheduled for 30 minutes and involved education tailored to both procedure and patient. The following topics were addressed: activity, medications (safety, dosing, and administration), incisional care, nutrition, and follow-up appointments. The patient was given a discharge folder with all

the periprocedural safety remained controversial, 9 , 14 , 17 and thus the 2012 AHA/ASA Guidelines for the Management of Aneurysmal Subarachnoid Hemorrhage suggested that coiling with stent placement should only be considered when less risky options have been excluded. 5 With the improvement of neurointerventional devices and experiences on ruptured aneurysm embolization, several recent studies reported comparable complication rates between coiling with stent placement and coiling without stent placement on acutely ruptured aneurysms. 3 , 4 , 7 , 21 Our previous
