Comparative Study
Asleep robot-assisted surgery for the implantation of subthalamic electrodes provides the same clinical improvement and therapeutic window as awake surgery.
To study the impact of not performing awake clinical evaluation during the robot-assisted implantation of subthalamic nucleus deep brain stimulation (STN-DBS) electrodes on the stimulation parameters and clinical outcomes in patients with Parkinson disease (PD). ⋯ Asleep, robot-assisted implantation of STN-DBS electrodes (with accurate identification of the STN and positioning of the DBS lead) produced the same motor results and TW as awake surgery.

The anterior transpetrosal approach (ATPA), during which the trigeminal nerve (TN) is manipulated, has a risk of eliciting the trigeminocardiac reflex (TCR). The aim of this study was to assess the risk of TCR during ATPA. ⋯ This study suggests that TCR is related to Meckel cave tumor size and tumor adhesion to TN in ATPA. To our knowledge, this is the first report describing TCR during ATPA.

Finite element models have been widely used to predict biomechanical parameters of the cervical spine. Previous studies investigated the influence of position of rotational centers of prostheses on cervical biomechanical parameters after 1-level total disc replacement. The purpose of this study was to explore the effects of axial position of rotational centers of prostheses on cervical biomechanics after 2-level total disc replacement. ⋯ Based on the present analysis, the SE-IE construct is recommended for treating cervical disease at the C4-C6 level. This study may provide a useful model to inform clinical operations.

The purpose of this study was to assess the feasibility of minimally invasive transforaminal lumbar interbody fusion (TLIF) and bilateral decompression via a unilateral approach that was performed with a novel working retractor with an endoscopic system for degenerative lumbar spondylolisthesis associated with spinal stenosis, to minimize surgical trauma without compromising the quality of the treatment outcome. ⋯ The use of navigation-assisted endoscopic TLIF with bilateral decompression via a unilateral approach appears safe and feasible. The endoscopic surgical procedure may be an alternative surgical option for degenerative lumbar disease.

This study aims to assess whether the A1 segment hypoplasia is a risk factor for unfavorable radiologic and clinical outcomes of surgical clipping anterior communicating artery (ACoA) aneurysm. ⋯ A1 segment hypoplasia is a significant independent risk factor for unfavorable clinical outcomes of surgical clipping ACoA aneurysm and ACA infarction after surgery.
