BACKGROUND: To compare the safety and efficacy of a rotational aspiration atherectomy system (Jetstream) for the treatment of infrainguinal arteries in diabetic versus nondiabetic patients. METHODS: A total of 172 patients with Rutherford stage 1-5 lower limb ischemia were treated with rotational aspiration atherectomy between February 2006 and February 2007. Of these, 80 patients with type 2 diabetes mellitus (DM: 46.5%) were compared with 92 nonDM (53.5%) patients. Overall, 210 target lesions (99 DM; 111 nonDM) were treated, located in the superficial femoral (67% DM; 61% nonDM), popliteal (25% DM; 30% nonDM), and tibial (8% DM; 9% nonDM) arteries. Lesion characteristics were comparable in both groups, mean lesion length was 28.5 mm (DM) and 26.2 mm (nonDM); total occlusions were present in 29% (DM) and 32% (nonDM), and 15% (DM) and 14% (nonDM) were restenotic. RESULTS: In the entire cohort, device success was 99% (all but two lesions). The major adverse event (MAE) rate (death, index limb amputation, myocardial infarction, target lesion revascularization [TLR] and target vessel revascularization) in DM at 30 days was 2.5% (n = 2 planned amputations) and 0% in nonDM. At 6 and 12 months, MAE in DM was seen in 13.8% (11/80) and 25% (20/80) compared with 21.7% (20/92) and 31.5% (29/92) in nonDM, respectively. TLR rate through 12 months was 20% (16/80) in DM and 28% in nonDM (26/92). Overall, 1 year restenosis rate was 38.2% based on duplex. The ankle-brachial index, mean Rutherford categories, and walking impairment questionnaire did not differ between groups at baseline and were increased significantly in both study cohorts at 12 months. CONCLUSION: Jetstream-assisted atherectomy in infrainguinal arteries is safe and effective in DM compared with nonDM patients. In this short-lesion cohort, vessel patency in diabetics was as good as for non-DM at 1 year. TLR and MAE were higher by trend in nonDM, although planned amputations were seen only in DM. The clinical benefit was similar in both groups.
