Abstract
The Crosser catheter is a unique device that facilitates antegrade intraluminal recanalization by high-frequency vibration energy and cavitation. We used this device not only as a chronic total occlusion (CTO) crossing device, but also as a flossing device in stenotic lesions and we also evaluated the efficacy of this device when used with both the “Crosser preceding” and the “Guidewire preceding” in CTOs. Complications related to this device were investigated, too. We retrospectively analyzed a total of 90 consecutive patients with peripheral artery disease in the femoropopliteal artery and below-the-knee artery (BTA). Primary technical success was defined as the successful delivery of this device into the distal true lumen. Secondary technical success was defined as successful revascularization. The safety endpoints were events of angiographic complications, including the occurrence of detachment of the metal tip from the shaft, slow flow, dissections, and perforations. Overall primary technical success rate was 93.3% and the secondary technical success rate was 96.7%. Detachment and slow flow occurred 14.4 and 4.4%, respectively, with no occurrences of either dissection or perforation. A predictor of detachment was Proposed Peripheral Arterial Calcium Scoring System (PACSS) grade 4 (OR 14.6; CI 1.26–168.5; P = 0.032). The Crosser catheter is useful not only as a CTO crossing device used with both the “Crosser preceding” and the “Guidewire preceding”, but also as a flossing device in stenotic lesions. But we have to pay attention to complications related to the Crosser.
