Duplex scanning was used to characterize the qualitative and quantitative parameters of blood flow in portofemoral bypasses and distal anastomoses in the long-term (3-144 months) period after operation. In 50% of cases with an end-to-side anastomosis, the examination reverled arterial segment occlusions caudal to the anastomosis. 12.5% of patients showed the maintenance of antegrade blood flow in the native arteries (parallel with the bypass). Retrograde blood flow through the anastomosis was recorded only in 32.5% of cases. As a rule, it was restricted by 1-2 branches of the external iliac artery, reaching the internal iliac artery only in 5% of cases. After one year the cumulative retrograde patency of the end-to-side anastomoses constitute 59.1±7.2% and after 5 years it is equal to 18.6±9.9%. If the superficial femoral artery was patent, the volume blood flow in the bypass was higher. The rise of the volume blood flow was also induced by the presence of the retrograde patency of the anastomosis which was apparently linked with the origination of an additional runoff pool. This advantage is especially completely realized when the condition of the distal perceptive bed is poor.

KEY WORDS: aortofemoral reconstruction, distal anastomosis, duplex scanning.
