Prior to cannulation of the dorsalis pedis artery the collateral circulation through the plantar arch should be examined to evaluate the consequence of an occlusion of this artery. Since the performance of the Allen's test is impossible for assessment of the plantar arch, another suitable technique has to be chosen. We selected the photoelectric plethysmography. Toe pulses were recorded with photoelectric plethysmography in 20 neurosurgical patients. The pulse amplitudes were measured before and during successive compression of the dorsalis pedis and the posterior tibial artery. Obvious decrease or absence of the pulse wave during compression of the dorsalis pedis artery is indicating an inadequate collateral circulation and cannulation of this artery seems not to be safe. In our study this occurred in 4 of 32 examined feet (12.5 percent). The photoelectric plethysmography has proved to be a simple and accurate means for assessment of collateral circulation.
在对足背动脉进行插管之前，应检查通过足底弓的侧支循环，以评估该动脉闭塞的后果。由于无法通过艾伦试验评估足底弓，因此必须选择另一种合适的技术。我们选择了光电体积描记法。用光电体积描记法记录了20例神经外科患者的趾脉搏。在连续压迫足背动脉和胫后动脉之前和期间测量脉搏幅度。压迫足背动脉时脉搏波明显降低或消失表明侧支循环不足，对该动脉进行插管似乎不安全。在我们的研究中，32只受检足部中有4只出现这种情况（12.5%）。光电体积描记法已被证明是评估侧支循环的一种简单而准确的方法。
