Patient description (patient's own words): I got my tooth extracted and I could not stop bleeding for 30 min. I'm a 20 yo dude but I have Hemophilia type A treated with FVIII. My blood pressure was 95/60 and my pulse 105/min. I'm 70 kg. My uncle on my mom's side also has type A hemophilia. I also have a fatty swelling on my left arm and I was supposed to remove it. My FVIII activity was 40%.
