Palmar hyperhidrosis is effectively treated by thoracic sympathectomy. Previous reports revealed that palmar skin temperature and perfusion increased on focal palmar regions after treatment. This study aimed to investigate the blood flow change over the whole palmar surface after the procedure.
Thirty patients with severe palmar hyperhidrosis were included for study. Each participant received measurement of palmar skin perfusion by a laser Doppler image scanner 1 day before and 1 day after surgery. Concomitantly, palmar skin temperature was recorded by a contact thermometer probe. One patient underwent intraoperative recording of palmar skin perfusion.
Palmar skin perfusion and temperature increased significantly after thoracic sympathectomy. Intraoperative measurement performed for a patient showed a similar trend of increment of palmar skin blood flow.
The global skin perfusion of palms can be analyzed in real time by the laser Doppler image scanner. This technique could be useful for analysis of blood flow changes in other body surface regions after thoracic sympathectomy.
胸交感神经切除术可有效治疗手掌多汗症。既往报道显示，治疗后手掌局部区域的皮肤温度和灌注增加。本研究旨在探讨该手术后整个手掌表面的血流变化。
纳入30例重度手掌多汗症患者进行研究。每位参与者在手术前1天和手术后1天接受激光多普勒图像扫描仪测量手掌皮肤灌注。同时，用接触式温度计探头记录手掌皮肤温度。1例患者在术中记录手掌皮肤灌注。
胸交感神经切除术后手掌皮肤灌注和温度显著升高。对1例患者进行的术中测量显示手掌皮肤血流有类似的增加趋势。
激光多普勒图像扫描仪可实时分析手掌的整体皮肤灌注。该技术可能有助于分析胸交感神经切除术后其他体表区域的血流变化。
