Abstract: | In spite of a systemically increased clotting tendency in progredient arteriosclerosis there are locally restricted haemorrhagic sequelae following arterial vasoreconstruction. Because of the fact that each bleeding simultaneously includes the risk of wound infection with subsequent sepsis the formation of a haematoma is to be avoided in the surgical procedure. The development of disseminated intravascular coagulation caused by sepsis and that caused by massive haemorrhage are represented as to their clinical importance. Finally, an internationally accepted substitution concept for severe bleeding sequelae, e.g. in case of the rupture of an aortic aneurysm, is submitted. |
