One hundred forty-six angiographic findings of malfunctioning internal arteriovenous fistulas without any history of interventional procedures were reviewed. Angiographies demonstrated 110 cases of stenosis, 72 of occlusion, 5 of venous varicosity, and 13 of venous aneurysm. Of 182 stenotic lesions, 118 (65%) lesions (74 venous stenoses: 67%; 44 venous occlusions: 61%) were revealed within five centimeters of anastomoses. In 4 of 5 cases of varicosity, proximal venous occlusions were demonstrated. On the other hand, interventional procedures were performed in 81 cases of stenoses and 14 of occlusions in the manner of PTA and fibrinolysis. The initial success rate was 90% in stenotic lesions and 71% in occlusive lesions, not a statistically significant difference. Furthermore, there was no statistically significant difference in initial success rates according to anatomical location and lesion length. Although there was no statistically significant difference according to the angiographic findings of lesions, we would like to emphasize the importance of correct understanding of anatomical changes in the dialysis shunt and of early intervention to improve the initial success rate of PTA.
