Pleased to know that you are either psychic or the coroner who performed the autopsy. In case of the latter, please list your credentials and while you are at it, a copy of your autopsy report. Look who is calling me a "Drama Queen!" At least I am not posing as a medical examiner (or "playing one" on FR.)
Stroke is a result of the aortic dissection.

"Occlusion of aortic branch vessels from aortic dissection may result in stroke, renal failure, mesenteric ischemia, lower extremity ischemia, and paraplegia (caused by obstruction of the spinal artery)."
