Change in somatosensory evoked potentials detect an acute arterial stent occlusion in lower extremity during spinal surgery: Case report.

The authors report a case in which an acute thrombosis of a pre-existing arterial stent occurs in a patient's lower extremity during a lumbar spinal fusion surgery. The event was detected by acute changes in somatosensory evoked potentials (SSEPs) which were being monitored during the procedure. The neurophysiology technologist reported a 10 % increased latency and 50 % loss of amplitude in the left posterior tibial nerve recordings.

Effect of an Immersive Preoperative Virtual Reality Experience on Patient Reported Outcomes: A Randomized Controlled Trial.

Objective: To investigate the effect of exposure to a virtual reality (VR) environment preoperatively on patient-reported outcomes for surgical operations.

Background: There is a scarcity of well-developed quality improvement initiatives targeting patient satisfaction.

Methods: We performed a randomized controlled trial of patients undergoing cranial and spinal operations in a tertiary referral center.

Selection of patients for ambulatory lumbar discectomy: results from four US states.

Background Context: There is a persistent trend for more outpatient lumbar discectomies in the United States.

Purpose: To investigate the characteristics of the patients selected for ambulatory procedures.

Study Design: Retrospective cohort study.
