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.
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.
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.

在动脉疾病中，慢性完全闭塞（CTO）的再通具有挑战性，结果并不理想。Crosser®是一种新型技术，利用高频（20 KHz）振动能量来破碎闭塞性纤维粥样硬化斑块，并有助于穿过闭塞的血管。我们报告了一项单中心经验，该中心使用该导管作为外周慢性完全闭塞的主要器械。
该导管在外周 CTO 中连续使用 25 例患者。本研究中的外周 CTO 定义为 100%闭塞的血管，涉及髂动脉的任何节段或腹股沟韧带以下至分叉血管，这些血管已经闭塞超过 3 个月，根据患者长期存在症状的病史判断，过去 3 个月内症状没有恶化。程序成功定义为设备能够促进导丝穿过闭塞。所有血管造影均由两名操作员进行评估。收集人口统计学、血管造影变量和患者并发症的数据。
该设备连续用于 25 例患者，共治疗 27 例 CTO 病变。严重肢体缺血和跛行分别占患者的 32%和 68%。平均病变长度为 117 毫米（范围 10-300 毫米）。股浅动脉是最常见的病变部位（n = 20，74%）。Crosser 辅助导丝再通在 11 个病变（41%）中实现，而任何器械的最终总体手术成功率为 63%（n = 17）。5 个病变发生穿孔，其中 1 个直接归因于该器械。
