Patient description (medical language): A 20-year-old man comes to the emergency due to bleeding after a tooth extraction.  The bleeding has persisted for approximately 30 minutes despite constant direct pressure.  He is a known case of Hemophilia type A treated with FVIII. Blood pressure is 95/60 mm Hg and pulse is 105/min. His weight is 70 Kg. Family history is positive for Hemophilia type A in his maternal uncle. He also has a lipoma on his left arm which he plans to remove surgically. His FVIII activity is 40%.

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%.

Does the patient match the trial criteria? Contradiction
