Full Endoscopic Lumbar Diskectomy for Lumbar Disk Herniation in the Presence of a Low-Lying Cord.

Background: The distal extent of the spinal cord is most often at the level of the L1 or L2 vertebral body. In rare cases, a low-lying cord extends more distally. In this scenario, pathology that normally causes radiculopathy may cause myelopathy due to compression of the cord rather than nerve roots of the cauda equina.

Shock Wave Enhances Angiogenesis through VEGFR2 Activation and Recycling.

Although low-energy shock wave (SW) is adopted to treat ischemic diseases because of its pro-angiogenic properties, the underlying mechanism remains unclear. This study aimed at testing whether SW-induced angiogenesis may be through endothelial vascular endothelial growth factor receptor 2 (VEGFR2) signaling and trafficking. Phosphorylation of VEGFR2-Akt-eNOS axis and production of nitric oxide (NO) were determined in human umbilical vein endothelial cells (HUVECs) treated with SW.
