[Intraoperative diagnosis in vascular surgery (author's transl)].

The different methods of intraoperative diagnosis in vascular reconstructive surgery are described. Intraoperative angiography is of importance in the morphological assessment of reconstructive procedures, whilst functional assessment is based on pressure difference and basic and peak flow determination. The peripheral resistance can be calculated from these parameters. With intraoperative diagnosis the immediate postoperative occlusion rate is lowered and the haemodynamic state in the reconstructed part can be better judged, which is of prognostic value in long-term functional terms.
