A procedure that involves the injection of a small amount of one’s own blood into the epidural space around (not in) the spinal canal in order to close a hole (or holes) in the dura of the spinal cord. As the blood clots, it forms a patch/seal in the area of the hole (or holes), and thus, stops the leaking of cerebrospinal fluid.  The holes in the dura are usually caused by a prior lumbar puncture (spinal tap), but can also arise as the result of trauma, surgery, chiropractic manipulations, bony abnormalities of the spine, or can occur spontaneously due to an underlying heritable disorder of connective tissues, such as Ehlers-Danlos Syndrome or Marfan Syndrome, etc.

 

 

Synonyms:
epidural blood patch, epidural blood patches, Epidural Blood Patches, blood patch, blood patches

Bridges are built as a means to assist people in getting over the things that obstruct their path. We are constantly facing obstacles when it comes to our health, so we decided to build a bridge! Chiari Bridges is a non-profit network built by Chiarians for Chiarians. Our goal is to provide information, substantiated by published studies, in a way that is easy to understand. We encourage readers, to not only read our articles, but look up every study for themselves and read that too. Print it out and sit down with a highlighter; read it as many times as necessary until you understand; then use it to talk to your doctors. Our doctors are under no obligation to read our articles, but they should be willing to read officially published studies from journals, especially those specific to their profession. As many of our authors are patients as well, all authors sharing original pieces will be writing under pseudo-ghost names, to protect them from being black-listed by their doctors. Chiari Bridges is not affiliated with any physician or medical group. You should in no way use this site as a replacement for diagnosis, treatment, or medical from a qualified medical professional. The information provided on our website is strictly for educational purposes, in order to help further the understanding of Chiari, and its associated conditions. Our goal is to share our collective experiences and the information we have gathered, with those in need of answers, that it may increase your knowledge and guide you in conversations with your doctors.
