A prototype directional atherectomy catheter (Omnicath) was evaluated in four Yucatan microswines. Atherectomy was performed on iliac or aortic target lesions. After control angiography, the animals were sacrificed and the target arteries were examined histologically. Atherectomy resulted in arterial ruptures in three cases, and the track of the blade was measured to be of an average depth of 0.38 mm. Maneuverability was satisfactory but aspiration was not efficient. Precise localization of the atherectomy window was difficult. We conclude that modification of the catheter seems mandatory before use in humans.
在四只尤卡坦小型猪身上对一种原型定向旋切导管（Omnicath）进行了评估。对髂动脉或主动脉的目标病变进行旋切术。在对照血管造影后，处死动物并对目标动脉进行组织学检查。旋切术导致三例动脉破裂，测得刀片轨迹的平均深度为0.38毫米。可操作性令人满意，但抽吸效率不高。旋切窗口的精确定位困难。我们得出结论，在用于人体之前，似乎必须对导管进行改进。
