Surgery for ruptured aortic coarctation is complex and usually takes 6-8 hours. Extracorporeal circulation is required to replace the ruptured aorta and aortic arch during aortic coarctation surgery with cryoablation. Postoperative hemorrhage is a major complication, and it takes a long time to stop bleeding after surgery. It is important to note that intraoperative hemostasis is critical, and if there is no postoperative bleeding, the procedure can be completed in 6-8 hours. If the patient has difficulty in stopping bleeding, the operation may take longer. With the improvement of current technology, the incidence of bleeding is low, so patients do not need to worry too much.
