Study Arms:
- ACT guided heparinization (Type: EXPERIMENTAL): Heparin is given to reach an ACT of 200-220 seconds. At the start of the procedure, before any heparin is given, a baseline ACT measurement is performed. 3-5 minutes before clamping of the aorta 100 IU/kg bodyweight of heparin is administrated intravenously. 5 minutes after administration of heparin, ACT measurement is performed.
- 5 000 IU of heparin (Type: ACTIVE_COMPARATOR): A single dose of 5 000 IU of heparin is given 3-5 minutes before clamping of the aorta. No ACT measurements are performed, except for one ACT measurement after re-establishing blood flow and removing all clamps. Depending on that ACT value near the end of surgery, the local protamine can be given to neutralize the effect of heparin. Only on clarified indications extra doses of heparin or protamine are permitted, at the discretion of the attending vascular surgeon. Indications could be clot formation intravascular or in a prosthesis, excessive bleeding or prolonged operation duration. Deviations from protocol should be clearly stated with reasoning in the operative report.

Based on this trial design, predict the completion outcome and termination type (if applicable).
