Abstract/OtherAbstract:
BACKGROUND AND OBJECTIVE: Restenosis-rate after balloon-angioplasty of long segment tibial arterial disease is largely unknown. We investigated the restenosis-rates angiographically in patients with critical limb ischemia (CLI) due to extensive infrapopliteal lesions.
METHODS: Angioplasty for infrapopliteal lesions exclusively ≥80 mm in length was performed using dedicated 80-120 mm long low-profile balloons. Follow-up included angiography at 3 months and clinical assessment at 3 and 15 months.
RESULTS: Angioplasty was performed in 77 infrapopliteal arteries of 62 limbs of 58 CLI patients with a Rutherford class 4 in 16 (25.8%) limbs and Rutherford class 5 in 46 limbs (74.2%). Average lesion length was 18.4 cm. Treated arteries were stenosed in 35.1% and occluded in 64.9%. After 3 months, a clinical improvement (marked reduction of ulcer-size or restpain) was seen in 47 (75.8%) limbs, 14 (22.6%) limbs were clinically unchanged and 1 (1.6%) limb showed a clinical deterioration. Angiography at 3 months showed no significant restenosis in 24 of 77 (31.2%) treated arteries, a restenosis ≥50% in 24 (31.2%) arteries and a reocclusion in 29 of 77 (37.6%). At 15 months death rate was 10.5%. After repeat angioplasty in case of restenosis cumulative clinical results at 15 months were minor amputations in 8.1%, no major amputations resulting in a limb-salvage rate of 100% with no patient requiring bypass surgery.
CONCLUSIONS: Restenosis-rate after angioplasty of extensive infrapopliteal arterial disease is high and occurs early after treatment. Despite this the clinical results are excellent, especially given the length of the arterial segments diseased.
