NEUROSURGERY. Magnetic Resonance Thermometry-Guided Laser-Induced Thermal Therapy for Intracranial Neoplasms: Initial Experience

Jethwa, Pinakin R. MD; Barrese, James C. MD; Gowda, Ashok PhD; Shetty, Anil MBBS, ME; Danish, Shabbar F. MD

BACKGROUND: Laser-induced thermal therapy is a promising tool in the neurosurgeons armamentarium. This methodology has seen a resurgence in application as a result of advances in technology.

NEUROSURGERY. Angiographic Detection and Characterization of “Cryptic Venous Anomalies” Associated With Spinal Cord Cavernous Malformations Using Flat-Panel Catheter Angiotomography

Pearl, Monica S. MD; Chen, James X. BS; Gregg, Lydia MA, CMI; San Millàn, Diego MD; Belzberg, Allan MD; Jallo, George MD; Gailloud, Philippe MD

BACKGROUND: Spinal cord cavernous malformations (CMs) are associated with 2 types of angiographically occult “cryptic venous anomalies,” which differ in location with respect to the spinal cord. The anatomic distinction between superficial and intramedullary is important in that the latter heighten the risks of CM resection.

JVIR. Percutaneous Image-guided Delivery for the Transplantation of Mesenchymal Stem Cells in the Setting of Degenerated Intervertebral Discs

J. David Prologo, MD , Ali Pirasteh, MD , Nathan Tenley, BS , Lewis Yuan, BS , David Corn, BS , David Hart, MD , Zach Love, MD , Hillard M. Lazarus, MD and Zhenghong Lee, PhD

Purpose: The delivery of mesenchymal stem cells (MSCs) to their site of action has remained a technical hurdle for clinical researchers in the expanding field of stem cell–based therapy. The purpose of this study was to test the feasibility of percutaneous image-guided needle delivery of bone marrow–derived human MSCs (hMSCs) to degenerated intervertebral discs (IVDs) in a preclinical model and to assess the containment of these cells within the IVDs.
