Use of PRP in Open Surgery for Type A Aortic Dissection

The goal of this clinical trial is to determine if autologous platelet rich plasma (PRP) can reduce the need for blood transfusions in patients undergoing open surgery for Type A aortic dissection. It will also evaluate the potential organ-protective effects of autologous PRP. The main questions it aims to answer are: 1. Does PRP reduce the amount of allogeneic red blood cell transfusions for participants? 2. Does PRP administration provide protective effects on organs (heart, liver, lungs, kidneys, brain) in participants? Researchers will compare the administration of autologous PRP with no PRP infusion to assess whether PRP can reduce blood transfusions and provide organ-protective effects in patients undergoing open surgery for Type A aortic dissection. Participants will: 1. Receive autologous PRP infusion during surgery 2. Undergo multiple checkups and tests before and after surgery 3. Be recorded for allogeneic red blood cell usage within 24 hours perioperatively and all allogeneic blood products usage during the entire hospitalization 4. Be assessed for organ function (heart, liver, lungs, kidneys, brain) and symptom-related outcomes through clinical evaluations
