Carotid atherosclerotic plaque occurs predominantly at the outer wall of the carotid sinus, and computational fluid dynamics (CFD) plays an important role in explaining plaque formation. The present study investigated the hemodynamic factors affecting carotid atherosclerotic stenosis. ⋯ Significantly decreased vascular WSS, dynamic pressure, strain rate, and total pressure gradient are key to atherosclerotic plaque formation at the carotid sinus.

Patients' expectations are considered to play an important role in subthalamic nucleus (STN) deep brain stimulation (DBS). We explored the relationship among expectations, satisfaction, and outcome 6 years after surgery. ⋯ Patients remain highly satisfied with STN DBS 6 years after surgery, although quality of life assessed by the PDQ-39 may return to baseline levels. Patients' expectations change over time and may influence patient satisfaction. Managing expectations before and after surgery plays an essential role in STN DBS.

Traditionally, nonoperative management with long-term antibiotics and bed rest has been recommended as first-line treatment for most patients with postoperative discitis. A recent trend in treatment under a limited range of indications has been to perform surgical débridement followed by long-term administration of antibiotics. This descriptive study investigated whether transforaminal lumbar interbody débridement and fusion (TLIDF) combined with intravenous antibiotics is appropriate to manage postdiscectomy discitis. ⋯ Based on previously reported data and the findings of this study, we suggest that surgical intervention should be used in certain cases, as it can achieve better outcomes than conservative treatment. We recommend a novel single posterior approach with TLIDF and posterior pedicle screw instrumentation for management of postdiscectomy discitis.

Selection of anterior versus posterior surgery for multilevel (≥3) cervical spondylotic myelopathy (MCSM) continues to be controversial. A comparison between anterior cervical discectomy and fusion (ACDF) with ROI-C cage and laminoplasty was made to determine the better treatment for MCSM. ⋯ ACDF with ROI-C cage has a similar clinical efficacy to LMP for patients with MCSM. There was less blood loss, shorter hospital stays, and improved sagittal balance when ACDF was used. However, a greater decrease in range of motion was observed after ACDF. Preoperative occupying ratio and Japanese Orthopaedic Association score are potential risk factors for different outcomes.

The intrapetrous carotid artery (IPCA) is one of the most unexplored anatomic regions, and its 3-dimensional reconstruction in living subjects is still missing. This study aims to describe the IPCA on 3D models extracted from head computed tomography (CT) scans. ⋯ This study provides data concerning not only linear and angular measurements, but also volumes of the IPCA, which are useful in planning surgical interventions of the cranial base.
