The value of intraoperative angioscopy in the detection and immediate correction of technical errors and deficiencies during vascular surgery has been previously documented. The inability to see through blood remains the most significant limitation to the general application of angioscopy. Local irrigation with a balanced salt solution is the most commonly used method to clear the blood from a restricted field in a particular vessel. We have developed a new catheter irrigation pump system (maximum flow rate 340 ml/min) to establish and maintain visibility of the field during intraoperative angioscopy. Furthermore, we have demonstrated the safety of irrigating with high volume flows in the peripheral arteries and defined the basic principles of irrigation for angioscopy. The prototype pump tested in this study provides a wide range of flow rates and permits precise measurements of the fluid delivered. The instrument's display and its control with a single foot pedal makes its use relatively simple, obviating the need for additional support personnel while increasing the efficacy and safety of the angioscopic examination and increasing the number of situations where angioscopy may be very useful.
术中血管镜检查在血管手术中检测和即时纠正技术失误及缺陷方面的价值此前已有文献记载。无法透过血液看清情况仍是血管镜检查普遍应用的最大限制。用平衡盐溶液进行局部冲洗是清除特定血管有限视野内血液最常用的方法。我们研发了一种新型导管冲洗泵系统（最大流速340毫升/分钟），以在术中血管镜检查期间建立并维持视野的清晰度。此外，我们已证明在外周动脉中进行高流量冲洗的安全性，并确定了血管镜检查冲洗的基本原则。本研究中测试的原型泵可提供广泛的流速范围，并能精确测量输送的液体量。该仪器的显示屏及用单只脚踏板进行控制使其使用相对简单，无需额外的辅助人员，同时提高了血管镜检查的有效性和安全性，并增加了血管镜检查可能非常有用的情况数量。
