AIM: The aim of the present paper was to make a report of the 12-month clinical outcomes of the DEBELLUM (Drug-Eluting-Balloon-Evaluation-for-Lower-Limb- mUltilevel-treatMent) randomized trial.

METHODS: From September 2010 to March 2011, 50 patients were randomized between drug eluting balloon (DEB, N.=25) and conventional angioplasty balloon (PTA, N.=25). Patients were symptomatic for claudication and critical limb ischemia, with de novo stenosis or occlusion in the femoropopliteal (SFA) and infrapopliteal (BTK) region. Only in the SFA primary stenting was allowed and postdilatation performed with DEB or PTA depending on the assigned group.

RESULTS: One hundred and twenty-two lesions were treated: 92 (75.4%) SFA, 30 (24.6%) BTK. Twenty (40%) patients presented multilevel concomitant femoropopliteal and infra-popliteal lesions. Late lumen loss (LLL) was 0.64±0.9 mm in DEB group vs. 1.81±0.1 mm in the control group (P=0.01). In non-stented segment LLL was 0.63±0.9 mm (DEB) vs. 1.70±0.6 mm (PTA), P<0.01. In the stent subgroup was LLL 0.65±0.2 mm (DEB) vs. 1.91±0.3 mm (PTA), P<0.01. In the femoropopliteal region the overall LLL was 0.61±0.8 mm for DEB vs. 1.84±0.3 mm for PTA (P=0.02). BTK the overall LLL was 0.66±0.9 mm (DEB) vs. 1.69±0.5 mm (PTA) (P=0.03). The overall TLR was 12.2% for DEB and 35.3% for PTA (P<0.05). Amputation rate was 4% (DEB) vs. 12% (PTA), P=0.36. Thrombosis was 4% (DEB) vs. 8% (PTA), P≥0.05. Major adverse events 24% (DEB) vs. 60% (PTA), P<0.05. ABI improved more in the DEB group: 0.81±0.3 vs. 0.68±0.13 (P=0.02). Fontaine stage increased (from II b to I) 80% DEB vs. 56% PTA (P<0.05).

CONCLUSION: Results confirm and reinforce initial 6-month outcomes. In.Pact DEB balloons can be considered efficient to reduce restenosis rate.
