Video Rate Blood Flow Imaging for Reconstructive Plastic Surgery

重建整形手术是切除乳房、头部、颈部和其他部位癌变肿瘤的前沿手术。肿瘤切除后的重建通常需要用其他身体部位的组织（如皮肤、脂肪、肌肉、骨骼）代替切除的组织来完成手术。移植的组织依靠充足的血液供应来避免完全或部分衰竭。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血液流动的方法，使外科医生能够在手术过程中优化组织血液流动。新的LSI技术以视频帧率扫描高达15cm x 20cm的区域；比其他技术更大更快。本提案的目的是研究将新技术应用于重建整形手术的可行性。这将使患者受益，避免因重建失败而需要额外手术的创伤，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.
