This week we revisited three of our patient storytellers sharing their experiences with spinal CSF leak due to CSF-venous fistula. Kathy’s only symptom was pain when she coughed. Patty had several ear surgeries before it became clear that her leak was spinal, and not skull-based. And Alice suffered head pain after a sinus infection, but ultimately discovered there was nothing wrong with her head. All three had a spinal CSF leak due to CSF-venous fistula, which occurs when there is an an abnormal channel between the space where cerebrospinal fluid is and a vein outside the dura mater. You may find more information about CSF-venous fistula in our collection of 2021 Publication Abstracts.
