Intercrural systolic blood-pressure differences did not exceed 10 mmHg in 22 healthy infants who were term, pre-term or small for their gestational age (three); as measured simultaneously in both legs with 3-cm wide thigh cuffs and mercury-in-silastic strain gauges around the calves. In 13 infants with indwelling umbilical artery catheter and normal angiographic findings in both legs, blood-pressure differences were similarly low in a majority of the infants, but in three of these intercrural differences of 15-20 mmHg were found. Resting and submaximal arterial leg blood-flow, measured with venous occlusion plethysmography, showed larger intercrural differences than blood-pressure, and did not add further information. The results indicate that simultaneous systolic blood-pressure measurements in the legs, with strain gauge plethysmography, is a simple and risk-free noninvasive method, suitable, for example, for diagnosing thromboembolism in infants. An indwelling umbilical artery catheter seems to interfere very little with the arterial circulation in the catheterized leg.
对22名足月、早产或小于胎龄（3名）的健康婴儿进行测量，使用3厘米宽的大腿袖带和小腿周围的硅橡胶应变片式压力传感器同时测量双腿血压，结果发现跨腿收缩压差值不超过10 mmHg。在13名留置脐动脉导管且双腿血管造影结果正常的婴儿中，大多数婴儿的血压差值同样较低，但其中有3名婴儿的跨腿血压差值为15 - 20 mmHg。通过静脉阻断体积描记法测量静息和次极量腿部动脉血流，结果显示跨腿血流差异比血压差异更大，且未提供更多有用信息。结果表明，使用应变片式体积描记法同时测量双腿收缩压是一种简单且无风险的非侵入性方法，例如适用于诊断婴儿血栓栓塞。留置脐动脉导管似乎对置管侧腿部的动脉循环干扰极小。
