… To determine the success and complication rate of coil embolization of arteriovenous
fistulae on in situ saphenous vein bypasses. … 7 complications were observed in 6
bypasses: failure of placement and retrieving of coil (n = 4), thrombembolic complications
with thrombolysis (n = 3). The duration of intervention was 118.3 +/- 46.6 min, the contrast
material need was 277.03 +/- 94.0 ml, and the radiation exposure was 10 966 +/- 11 295
cGy/cm (2). Additional balloon dilatation was performed in 30 % of the … Coil-embolization …

Purpose: To determine the success and complication rate of coil embolization of
arteriovenous fistulae on in situ saphenous vein bypasses. Materials and Method: 82 AV-
fistulae on 30 bypasses (28 patients, 20 men, age 62.5 {+-} 8.3 years) were treated using
coils. The success rate, complications, duration, amount of contrast material and radiation
exposure were measured. Color-coded duplex sonography was performed 1-2 days and up
to 6-18 months after embolization. Results: The success rate was 68.3%. The reasons for …
