Recent increase of atheosclerosis obliterans and abdominal aortic aneurysm patients are remarkable and an establishment of safe procedure for those cases are urgent concern for us. We developed a new device to check visceral circulation using transanal Doppler flowdetector. This technique is non invasive and more than 120 cases experiences showed that visceral or pelvic circulation were easily demonstrated by this device. And it offered a index for safe surgical procedures. In abdominal aortic aneurysm surgery, we could ligate three branches (inferior mesenteric and bilateral internal iliac arteries) without any postoperative complications when we could hear good signal via the superior mesenteric artery to the rectum. On the other hand, hip claudication and vasculogenic impotence were investigated using this technique and diagnostic or therapeutic usefulness was ascertained. And retroperitoneal approach for aorto-iliac surgery was well controled visceral circulation by usage of this device. Other technical improvements for Doppler probe provided for easy handling of this technique until we got almost zero false negative rate.

近年来，闭塞性动脉粥样硬化和腹主动脉瘤的发病率显著增加，建立一种安全的治疗方法是我们迫切关注的问题。我们研制了一种新的经肛门多普勒血流检测装置。120多例临床应用表明，该装置能较好地显示内脏或盆腔循环。并为安全手术提供了一个指标。在腹主动脉瘤手术中，我们可以结扎三个分支（肠系膜下动脉和双侧髂内动脉），而没有任何术后并发症时，我们可以听到良好的信号，通过上级肠系膜动脉到直肠。另一方面，髋关节跛行和血管性阳痿进行了调查，使用这项技术和诊断或治疗的有用性被确定。通过使用该装置，腹膜后入路主髂动脉手术可以很好地控制内脏循环。多普勒探头的其他技术改进使该技术易于操作，直到我们获得几乎为零的假阴性率。
