Abstract

BACKGROUND

In a prospective study, we evaluated the blood perfusion and the blood flow of anterolateral thigh (ALT) flap by both near-infrared spectroscopy and color Doppler ultrasonography. Moreover, we assessed the ability of the perforator flap to reconstruct infected wounds of the lower extremity in 11 patients.

METHODS

Near-infrared spectroscopy showed excellent oxygen saturation, and Doppler ultrasonography documented excellent blood flow and decreased vascular resistance in the ALT flap postoperatively.

RESULTS

All flaps were successful and all wounds healed uneventfully within 2 weeks without any signs of recurrences or persistent infection. All patients achieved acceptable gait function after rehabilitation.

CONCLUSIONS

Apart from the mandatory role of thorough debridement, our results indicate that the ALT flap offers rich blood supply to the recipient area, thus contributing to the sterilization and healing of an infected wound within a short time period.

摘要

背景

在一项前瞻性研究中,我们通过近红外光谱法和彩色多普勒超声评估了股前外侧(ALT)皮瓣的血液灌注和血流情况。此外,我们评估了穿支皮瓣对11例下肢感染伤口的重建能力。

方法

近红外光谱显示氧饱和度良好,多普勒超声记录了术后ALT皮瓣血流良好且血管阻力降低。

结果

所有皮瓣均成功,所有伤口在2周内顺利愈合,无复发或持续感染迹象。所有患者康复后步态功能均可接受。

结论

除了彻底清创的必要作用外,我们的结果表明,ALT皮瓣为受区提供了丰富的血液供应,从而有助于在短时间内使感染伤口消毒并愈合。
