Arm Intervention/treatment
Experimental: Foot pump (A-V Impulse, 6000 Series)
In OR before operation starts randomized to foot pump treatment post operative. Pump placed on foot immediately after operation is finished. Foot pump will be left on foot until full mobilization is reached
Device: A-V impulse 6000 Series
foot pad and pump

Active Comparator: Standard treatment (compression)

In OR before operation starts randomized to standart treatment for edema after in situ bypass.

Short-stretch bandage from toes and up yo the upper thigh 40 mm Hg

Device: Standard treatment (compression)
Short-stretch bandage from toes and up yo the upper thigh 40 mm Hg

Primary Outcome Measures :
  1. Reduction of wound complications in the foot pump group [ Time Frame: From randomization until 12 month examination (individual finish examination) ]

    reduction from 18% to 14 %.Inspection of the operated leg at day 2 and 4 and at discharging. After discharging at 30 days, 6 month and one year.More frequent inspections can be necessary depending on the situation and the condition of the patient.

    Inspection of secretion from the operations cicatrices, necrosis and diastasis of the wounds, signs of infections, hematoma subcutaneously in the operation area, edema, temperature and color of the skin

Secondary Outcome Measures :
  1. Reduction of leg edema 50%, [ Time Frame: 5 to 30 days ]
    10 cm below the patella on the operated leg three days post-operation in patients treated with impulsive compression in comparison to non-treated.

  2. Time to mobilization in pump treated patients [ Time Frame: 1 to 7 days ]
    Patient can get out of bed and go to the toilet.

  3. Length of stay in hospital [ Time Frame: 10 to 14 Days ]
