Twenty-three patients undergoing oral reconstructive surgery with radial forearm free flaps had a vascular assessment of the forearm preoperatively. Segmental upper limb pressures were measured and colour flow duplex visualization of forearm vessels and blood flow done. In 18 the blood pressure and flow were within normal limits, but five (22%) showed either unilateral or bilateral arteriopathy or aberrant vascular anatomy. Identification of pre-existing vascular disease helps to rationalize the selection of donor vessels, reduces the risk of ischaemic damage to the hand after disruption of the radial artery and may be of benefit in reducing the incidence of failure of free flaps.
23例行桡侧前臂游离皮瓣口腔重建手术的患者术前对前臂进行了血管评估。测量了上肢节段性血压，并对前臂血管和血流进行了彩色多普勒血流显像。18例患者的血压和血流在正常范围内，但5例（22%）显示有单侧或双侧动脉病变或血管解剖异常。识别预先存在的血管疾病有助于合理选择供体血管，降低桡动脉离断后手缺血性损伤的风险，可能有助于降低游离皮瓣失败的发生率。
