Masterclass #8: I am a leptomeningeal dural malformation: what does that mean? How do you treat me?

A critical first step in treating leptomeningeal malformations is to understand what they are, and this masterclass begins sees Professors Jacques Moret and Laurent Spelle exploring the anatomy of these malformations looking at the leptomeninges and the pathologies of the peri-arterial and peri-venous spaces.

Join them to:

• Understand the nature of cortical arterial and venous bleeding; for instance, what induces subarachnoid hemorrhages.
• Examine the danger involved in the direct draining of leptomeningeal fistulas into the cortical veins or the neurological risk in venous drainage itself.
• Discover why a vein in hyper-pressure could be considered more dangerous than an occluded vein.
• Consider whether every leptomeningeal fistula should be treated, even an incidental one… and, if they yes, how soon should treatment begin after bleeding is detected, and what strategy should be employed?
  • A surgical approach?
  • An endovascular venous or endovascular arterial approach?

Illustrated through a series of specially selected cases, including an interactive discussion with the expert panel, discover why Prof. Laurent Spelle concludes that “leptomeningeal dural malformations may be spontaneously the most dangerous, but fortunately, are easily treated when you discover the shunt….”
