re: BJJ practitioners: any concern about carotid artery dissection?

quote:

---

Over the weeks since I initially injured it, a blood clot had been forming at the injury site as my body tried to heal itself, much as a scab would form over an open-air cut or scrape. Eventually, that clot became unstable, most likely due to the changes in arterial blood pressure from the arm triangle choke I was put in. A part of the clot dislodged and began rapidly moving through my vertebral artery into my brain, where it eventually caused a blockage. I subsequently suffered a series of ischemic strokes in my cerebellum as the blood supply was cut off. Without constant blood supply, the tissues of the brain begin to die in a matter of minutes.
