In this issue of Neurosurgery News, Drs. Bradley Gross, Ashutosh Jadhav, Tudor Jovin, Brian Jankowitz, and Phillip V. Parry discuss topics including stent-assisted aneurysm coiling, dural arteriovenous fistulas, extending the role of the neuroendovascular surgeon in a deployed environment, and improving outcomes in the acute stroke population with endovascular therapy.

Educational objectives:

Upon completion of this activity, participants should be able to:

  • Recognize the rationale for the usage of stents to assist coiling of intracranial aneurysms.
  • Identify some of the limitations of first generation intracranial stent technology and how the new ATLAS stent may overcome some of them.
  • Recognize treatment options and overall results for dural arteriovenous fistulas.
  • Review presentation modalities for dural arteriovenous fistulas.
  • Identify risk factors for an aggressive course for dural arteriovenous fistulas.
  • Improve civilian understanding about Neurosurgical capabilities in a deployed environment.
  • Increase patient outcomes by implementing peripheral vascular procedures that can be safely performed by someone with a basic endovascular skill set.
  • Improve diagnostic skill set for being able to identify cerebrovascular pathology.
  • Closely follow recommended guidelines by referring patients for endovascular therapy with acute ischemic stroke in the setting of large vessel occlusive disease.
  • Increase patient outcomes by considering IV thrombolysis for patients presenting within 4. 5 hours of symptoms onset after acute ischemic stroke
  • Improve management of acute ischemic stroke in order to maximize the number of patients that will benefit from available therapies.
