To evaluate the surgical outcome of using a trepan to treat single-segment ossification of ligamentum flavum under endoscopy and the clinical value of the new surgical treatment. ⋯ The visual trepan technique using a spinal endoscope can be used to treat single-segment ossification of ligamentum flavum. Advantages include less trauma, faster recovery, and lower cost. However, more cases and long-term follow-up are required to further evaluate the clinical effectiveness and safety of this surgical method.

Evolution of the Anterior Approach in Lumbar Spine Fusion.
The anterior approach to lumbar spine fusion, termed anterior lumbar interbody fusion (ALIF), is becoming increasingly popular, with numerous recognized indications, well-defined advantages, and potential complications. From its first theoretical description in 1932 and the first operation published in 1933 to the more recently reported less invasive procedures, an anterior approach to the lumbar spine has many technical variations. Here we describe the evolution of the anterior approach to the lumbar spine, from a hugely invasive transperitoneal route to the current minimally invasive retroperitoneal approach. Many advantages have been advocated for the ALIF approach, and some issues about intraoperative and postoperative complications need to be evaluated in a more specific and homogeneous manner.

Resection of intraventricular lesions remains a challenge for modern neurosurgery. Endoscopy has provided great advantages in ventricular surgery, even if limited in terms of operability, due to the restricted working channel and impossibility for bimanual surgical manipulation. Tubular approaches have been considered as an option, enabling the use of microsurgical techniques, minimizing violation of brain tissue. The aim of our study was to describe and critically evaluate the use of portal surgery to access lateral ventricles in terms of surgical exposure and operability. ⋯ Ventricular tubular systems provide adequate visualization, with minimal brain retraction, improving operability as compared with endoscopy. Endoscopic assistance critically widens surgical exposure in blind spots without providing concomitant significant advantage in terms of surgical operability.

To test whether robot-assisted surgery can improve prognosis of small-volume thalamic hemorrhage and to provide a surgical basis for treatment of small-volume thalamic hemorrhage. ⋯ Robot-assisted drainage of thalamic hemorrhage can improve prognosis and reduce the incidence of pneumonia and renal dysfunction.

Reports have emerged describing the successful endovascular recanalization of the chronically occluded internal carotid artery (COICA). The impact this restoration of flow has on the sensitive carotid sinus baroreceptors has not been previously described. In this manuscript, we present the largest COICA surgical series to date, with a specific focus on perioperative heart rate abnormalities. ⋯ Bradycardia associated with angioplasty of the carotid bulb was observed in the majority of patients receiving COICA revascularization. A small percentage of these patients were symptomatic. Our results suggest that carotid sinus baroreceptors remain active while residing in a complete arterial occlusion, and close monitoring is necessary during balloon angioplasty of the proximal COICA.
