Angiography and ultrasound techniques are well established methods for the detection of extracranial vascular disease, but they only allow indirect demonstration of changes in the vessel wall. The development of an ultra-thin fiberscope allows direct demonstration of the pathogenic process in the vessel lumina by angioscopy. The percutaneous transfemoral approach for carotid angiography enables the combination of both methods. After development of an appropriate catheter system we investigated the value of this method producing definite lesions by vascular surgery in adult dogs followed by repeated examinations using angioscopy. Vessel wall alterations such as stalagmite-shaped lesions, subintimal bleeding and thrombotic layers, plaques, ulcerations and postoperative intimal bridging or ablation, which could not be identified by angiography have been analysed with high resolution of details using angioscopy with a video monitoring technique.
血管造影术和超声技术是检测颅外血管疾病的成熟方法，但它们只能间接显示血管壁的变化。超薄纤维内镜的发展使得通过血管内镜直接显示血管腔内的致病过程成为可能。经皮股动脉途径进行颈动脉血管造影可将这两种方法结合起来。在开发出合适的导管系统后，我们研究了这种方法的价值，即通过血管手术在成年犬身上制造明确的病变，然后使用血管内镜进行重复检查。血管壁的改变，如石笋状病变、内膜下出血和血栓层、斑块、溃疡以及术后内膜桥接或剥脱，这些血管造影无法识别的病变，已通过带有视频监测技术的血管内镜以高分辨率细节进行了分析。
