Title: Haemocomplettan® P in Patients Experiencing Acute Bleeding While Undergoing Aortic Replacement Surgery
Brief Summary: The primary purpose is to show that administration of Haemocomplettan® P significantly reduces the amount of blood products needed during aortic surgery.


Options:
A: Inclusion Criteria:

* The participants aged 18 years or above who were undergoing emergency aortic arch surgery involving moderate hypothermic circulatory arrest for an acute type A aortic dissection

Exclusion Criteria:

* The participants with congenital or acquired coagulation disorders, previous surgery at the same site, death prior to planned surgery, stroke or myocardial infarction within 2 months before surgery and use of aspirin, clopidogrel or vitamin K antagonists within 2 to 5 days before surgery.
B: Inclusion Criteria:

* Eighteen years of age or older
* Undergoing elective thoracoabdominal aortic replacement surgery (TAAA) or thoracic aortic replacement surgery (TAA)
* Understood and willingly given written informed consent (German language) to participate following an explanation of study background, restrictions, and procedures
* Experience clinically relevant bleeding of the microvasculature following removal of CPB during surgery

Exclusion Criteria:

* Positive pregnancy test, pregnancy or lactation
* Women of child bearing age not using a medically approved method of contraception during the study
* Previous aortic replacement at the same aortic site (redo surgeries)
* Undergoing an emergency operation
* Proof or suspicion of a congenital or acquired coagulation disorder (e.g. VWD or via severe liver disease)
* Myocardial Infarction (MI) or apoplexy in the 2 months preceding study surgery
* ASA administration in the 3 days preceding study surgery, and a pathological (\<74.5 U) ASPI Multiplate® test immediately preceding surgery begin
* Clopidogrel administration in the 5 days preceding study surgery, and a pathological (\<31.1 U) ADP/PG Multiplate® test immediately preceding surgery begin
* Tirofiban administration in the 2 days preceding study surgery, and a pathological (\<94.1 U) TRAP Multiplate® test immediately preceding surgery begin
* Phenprocoumon administration in the 5 days preceding study surgery, and an INR \> 1.28 immediately preceding surgery begin
* Participation in another clinical study in the 4 weeks preceding aortic replacement
* Sensitivity to any of the components of study medication, or to MPs with a similar chemical structure to any of the components of study medication
* Any indication that the restrictions or procedures of the study may not be adhered to (e.g. an uncooperative attitude)
* Any indication that the study restrictions, procedures, or consequences therein have not been considered or understood, such that informed consent cannot be convincingly given
* Multiple morbidities, with a notably constrained remaining length of life
C: Inclusion Criteria:

At Screening:

* Undergoing elective open surgical procedures on any part of the aorta requiring cardiopulmonary bypass (CPB), with or without other cardiac surgical procedures (e.g. valve replacement or repair, coronary artery bypass grafting, etc.).
* 18 years of age or older.
* Written informed consent for study participation obtained before undergoing any study specific procedures.

Intraoperative (at the 1st 5-minute bleeding mass):

* A 5-minute bleeding mass of 60 to 250 g following discontinuation of CPB, administration of protamine, and establishment of surgical hemostasis.
* Minimum core body temperature 35°C, measured according to local practice.
* Activated clotting time ± 25% of baseline levels.
* Blood pH \> 7.3.

Exclusion Criteria:

At Screening and/or baseline:

* Undergoing emergency aortic repair surgery.
* Reoperative aortic surgery at the same anatomic site as the original procedure such as replacement of a previously placed aortic graft. Resternotomy and rethoracotomy are permitted.
* Any operation for infection.
* Proof or suspicion of a congenital or acquired coagulation disorder (e.g. Von Willebrand's disease, hemophilia or severe liver disease) or a prothrombotic disorder (e.g. protein C or S deficiency).
* Myocardial infarction (MI), acute coronary syndrome or stroke in the 2 months preceding study surgery.
* Low molecular weight or unfractionated heparin in the 24 hours preceding study surgery.
* Clopidogrel administration within 5 days preceding study surgery or prasugrel administration within 7 days preceding study surgery or ticagrelor administration in the 48 hours preceding study surgery.
* Factor Xa inhibitors within 2 days preceding study surgery.
* IIb/IIIa antagonist administration in the 24 hours preceding study surgery.
* Use of direct thrombin inhibitors: within 3 days preceding study surgery for dabigatran and within 24 hours preceding study surgery for all others.
* An international normalized ratio \> 1.3 immediately preceding the start of surgery.

Intraoperative (at the 1st 5-minute bleeding mass):

* Use of any systemic hemostatic therapy (such as FFP, platelets, prothrombin complex concentrates) from the beginning of surgery until IMP administration.
D: Inclusion Criteria:

* Emergency
* Trauma patient admitted in participating trauma care centers
* Severe bleeding requiring transfusion with 4 units of red blood cells and 4 emergency plasma.
* Inclusion performed within the first 6 hours after trauma.

Exclusion Criteria:

* Patient taking anticoagulants
* Patients who have received hemostatic treatment during transport (tranexamic -acid excluded)
* Minor Patient
* Pregnant or breastfeeding women
