title: A novel catheter in patients with peripheral chronic total occlusions: a single center experience.
abstract: OBJECTIVE
  Recanalization of a chronic total occlusion (CTO) is technically challenging with less than optimum results in arterial disease. Crosser® is a novel technology that utilizes high frequency (20 KHz) vibration energy to fragment occlusive fibrous atherosclerotic plaque and helps in traversing the occluded vessel. We report a single center experience with this catheter as the primary device in peripheral chronic total occlusions.
  
  
  METHODS
  The catheter was used as the primary device in 25 consecutive patients with peripheral CTOs. The peripheral CTOs in this study are defined as 100% occluded vessels involving any segment of the iliac artery or below the inguinal ligament down to the trifurcation vessels which have been occluded for greater than 3 months judged by patient's history of longstanding symptoms with no worsening in the past 3 months. Procedural success was defined by the ability of the device to facilitate guide wire crossing of the occlusion. All angiograms were evaluated by two operators. Data on demographics, angiographic variables, and patient complications was collected.
  
  
  RESULTS
  The device was used in 25 consecutive patients and 27 CTO lesions were treated. Critical limb ischemia and claudication were the indications in 32 and 68% of the patients, respectively. Average lesion length was 117 mm (range 10-300 mm). Superficial femoral artery was the most common lesion site (n = 20, 74%). Crosser-assisted guide wire recanalization was achieved in 11(41%) lesions while the final overall procedure success rate with any device was 63% (n = 17). Perforation occurred in five lesions with one directly attributable to this device.
  
  
  CONCLUSIONS
  In this single center observational review, the Crosser device in peripheral CTO lesions had a procedural success of 41%. © 2010 Wiley-Liss, Inc.
