The CT scan was “inconclusive” for fistulas. But more importantly, it revealed a previously unknown “significant clot” in the superior vena cava which could be life threatening if it broke loose.
As a result, she is being admitted to the cardiac ICU for close monitoring. It will initially be treated with anti-coagulant (clot buster) drugs. Surgery is not being ruled out as a possibility though.
Keep up the prayers, good thoughts, etc please.
