[Usefulness of the Doppler velocimetry in patients undergoing direct arterial surgery].

Two patients with an atypical and particularly troubled history, due to numerous direct and indirect interventions of vascular surgery, have been monitored in haemodynamic investigation using only Doppler velocimetry. The use of angiography would have necessitated other general anaesthesiae which would have further compromised the already critical conditions of the patients. Doppler velocimetry proved suitable for surgical indication in emergency situations. The value of an arteriograph under general anaesthesia is, however, unquestionable in cases of choice surgery.
