A two-phase study investigated vascularity in idiopathic clubfeet (talipes equinovarus, TEV) undergoing a comprehensive soft tissue release. Great toe O2 saturation was measured by pulse oximetry in a consecutive series of 50 TEV (34 patients) in three foot positions: in feet at rest, in feet in maximal passive correction, and in feet immediately postoperatively. Oxygen saturation was between 94 and 100% in 100% of feet at rest, 95-100% in 90% of feet at maximal passive correction, 95-100% in 98% of feet immediately postoperatively, and 97-100% in 100% of feet 3 weeks' postoperatively. Doppler ultrasound studies were performed on 38 TEV. Dorsalis pedis (DP), posterior tibial (PT), and peroneal (P) pulses were recorded at preoperative resting posture, preoperative maximal passive correction, and 3 weeks postoperatively. At rest, DP pulse was present in 37 of 38 feet, PT pulse was present in all feet, and P pulse was present in 20 of 30 tested (67%), whereas 72% PT, 61% DP, and 50% P pulses were unchanged. Pulse oximetry and Doppler assessment are readily available, noninvasive, and reproducible means of monitoring vascular integrity in TEV.
一项分为两个阶段的研究对接受全面软组织松解术的特发性马蹄内翻足(TEV)的血管情况进行了调查。通过脉搏血氧饱和度测定法,对连续的50例TEV(34例患者)在三种足部位置测量了拇趾的血氧饱和度:足部处于休息状态时、足部进行最大程度被动矫正时以及术后即刻。在休息状态下,100%的足部血氧饱和度在94%至100%之间;在最大程度被动矫正时,90%的足部血氧饱和度在95%至100%之间;术后即刻,98%的足部血氧饱和度在95%至100%之间;术后3周,100%的足部血氧饱和度在97%至100%之间。对38例TEV进行了多普勒超声研究。在术前休息姿势、术前最大程度被动矫正时以及术后3周记录足背动脉(DP)、胫后动脉(PT)和腓动脉(P)的脉搏。休息时,38只足中有37只可触及DP脉搏,所有足均可触及PT脉搏,30只接受检测的足中有20只可触及P脉搏(67%),而72%的PT脉搏、61%的DP脉搏和50%的P脉搏无变化。脉搏血氧饱和度测定和多普勒评估是监测TEV血管完整性的便捷、无创且可重复的方法。
