Video Rate Blood Flow Imaging for Reconstructive Plastic Surgery

重建整形外科是切除乳房、头部、颈部和其他部位癌性肿瘤的第一线。肿瘤切除后的重建通常需要用来自其他身体部位的组织（即皮肤、脂肪、肌肉、骨骼）替换切除的组织，以完成手术。转移的组织依赖于足够的血液供应，以避免完全或部分失败。激光散斑成像技术（LSI）是一种新的快速观察皮肤和其他组织中血流的方法，使外科医生能够在手术期间优化组织血流。新的LSI技术以视频帧速率扫描高达15 cm x 20 cm的区域;比其他技术更大更快。这项建议的目的，是研究将新科技应用于再造整形外科的可行性。这将使患者受益，避免了需要额外手术的失败重建的创伤，因此将降低NHS的成本。

Reconstructive plastic surgery is in the front line for the removal of cancerous tumours of the breast, head, neck and other sites. Reconstructions following tumour removal usually require the replacement of removed tissue with tissue (i.e. skin, fat, muscle, bone) from other body sites to complete the procedure. The transferred tissues rely on an adequate blood supply to avoid complete or partial failure. The Laser Speckle Imaging technique (LSI) is a new and fast way of seeing blood flow in the skin and other tissues enabling surgeons to optimise tissue blood flow during surgery. The new LSI technique scans areas of up to 15cm x 20cm at video frame rates; larger and faster than other techniques. The purpose of this proposal is to examine the feasibility of applying the new technology for reconstructive plastic surgery. This will benefit patients by avoiding the trauma of a failing reconstruction requiring additional surgery and it will therefore reduce NHS costs.
