[Autovenous bypass in situ in distal occlusions of the arteries].
In patients with bad distal bed and blood flow along the bypass two functioning venous collaterals were left with the diameter less than 1 mm, with the blood flow volume 100-150 ml/min one collateral was left, if the volume was 150-200 ml/min it was not necessary to make an arterio-venous output. One-two functioning collaterals left did not influence the volume and linear velocity of blood flow along the bypass and the parameters of hemodynamics. 78 patients (91%) were discharged with the functioning bypasses and decreased ischemia. A year later thrombosis of the bypass was noted in 6 (14%) of 43 follow-up patients, stepwise liquidation of one or two collaterals was fulfilled in 5 patients due to a more than 1 mm dilatation. Prognostically the blood flow in the zone of a distal anastomosis less than 100 ml/min is thought to be most critical.
