| Popis: | We tested the value of hemobahn-endoprosthesis in a prospective, nonrandomized, clinical trial in PAD-patients with femoral artery occlusive disease. During 4 years we placed in 52 patients (55 extremities) a total of 78 hemobahn-endoprostheses for treatment of stenoses (15%) or occlusions (85%) of femoral artery. The average length of the treated lesions was 11.6 cm, the mean length of the hemobahn-endoprosthesis was 15.9 cm, the average device diameter 6.1 mm. In 45% of the patients we used cross-over and in 55% ipsilateral antegrade technique. Fontaine's clinical stages were II b (89%), III (2%) and IV (9%); there were 15 diabetics. The average period of follow-up was 33 months (1-52 months). The primary/secondary patency rates after the first year (n = 50) were 64% vs. 78%, after 2 years (n = 46) 61% vs. 76%, after 3 years (n = 32) 53% vs. 66% and after 4 years (n = 14) 29% vs. 50%. After the first experiences in 1998 with 10 stent-occlusions in 14 treated extremities, indications were checked and thereafter hemobahn was only used in "ideal indications" as segments with a length of > or = 1 cm proximal and distal without any obstruction, no lesions in the popliteal artery, at least one open lower leg vessel and no severe calcifications. The primary/secondary patency rates were significantly better after exclusion of nonideal patients treated during the first year: Thus, primary/secondary patency rates were 76 % vs. 90% after first year (n = 32), 74 % vs. 89% after second year (n = 38) and 71% vs. 83% after third year (n = 24); after 4 years of 8 treated arteries 4 were primary and 7 were secondary open. Hemobahn-endoprostheses are suitable for treatment of long femoral artery occlusions. The medium patency rate in "ideal indications" is higher than that obtained by angioplasty with or without uncovered stents. |
