Abstract/OtherAbstract:
The purpose of this study was to assess the technical performance and immediate procedural outcome of a new balloon catheter in the treatment of calcified lesions in infrapopliteal arterial disease. Sixty-one patients (81 vessels) with infrapopliteal arterial disease were evaluated. Seventy-four of the 81 treated vessels had total occlusions. The ReeKross 18 peripheral transluminal angioplasty catheter (ClearStream, Wexford, Ireland) is an 0.018-inch guidewire system with 4F sheath compatibility and a rigid shaft intended for enhanced pushability. Only technical procedural outcomes were recorded. In 37 of 61 patients (50 infrapopliteal severely stenosed or occluded vessels), an attempt with a standard balloon was made before the ReeKross 18 was used. In 24 patients, the ReeKross 18 was used as the primary catheter in 23 cases involving crural arteries and in 8 cases involving the foot. The ReeKross 18 crossed the lesion in 55 of 59 (93.2%) patients and 72 of 77 (94.5%) vessels, respectively. Postdilatation results for the 51 patients (64 target lesions) in whom ReeKross 18 balloon dilation was achieved showed <30% residual stenosis in all but 4 patients (5 lesions). Of the patients treated with the ReeKross 18 as the primary catheter, the technical success rate (no adjunctive treatment/stent) was obtained in 20 of 24 (83.3%) patients (27 of 31 [87.1%] target lesions). In the treatment of difficult calcified lesions, the choice of a high-pushability angioplasty catheter, such as the ReeKross 18, warrants consideration.
