Chemical & experimental study for viscenal circulation using trams am al Doppler probe

近年来动脉粥样硬化闭塞症和腹主动脉瘤患者的增加是显着的，为这些患者建立安全的手术程序是我们迫切需要关注的问题。我们研制了一种利用经肛门多普勒血流检测仪检测内脏循环的新装置。该技术是一种非侵入性的技术，120多例经验表明，该设备可以很容易地显示内脏或盆腔循环。它还为安全的外科手术提供了一个索引。在腹主动脉瘤手术中，只要肠系膜上动脉直达直肠信号良好，即可结扎肠系膜下动脉和双侧髂内动脉三支，无术后并发症。另一方面，使用这项技术研究髋部跛行和血管性阳萎，并确定诊断或治疗的有效性。腹膜后入路在腹主动脉-髂骨外科手术中能较好地控制内脏循环。多普勒探头的其他技术改进使这项技术易于操作，直到我们获得几乎为零的假阴性率。

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.
