A Novel Approach For Improving Flap Tolerance TO Ischemia H2S
Jason Spector MD

Basic Research Grant
Despite the ubiquity of microvascular free tissue transfer, a major limitation and source of morbidity in these procedures is related to reperfusion injury of the transferred tissue. Currently, the only accepted way to minimize ischemic injury is by rapid re-establishment of blood flow within the flap. Although some authors have reported improved tolerance to ischemia by rapidly cooling the flap during the ischemic interval, this practice is not universally accepted. Even the swiftest of microsurgical transfers exposes the flap to nearly one hour of ischemia time. Although the flap tissues generally "tolerate" this ischemic interval, even this limited period contributes to significant post-operative edema, especially in the most ischemia-sensitive tissues such as muscle and intestine. In more difficulty microsurgical transfers, longer periods of ischemia time may result in significant reperfusion injury ultimately leading to partial flap loss or flap failure. We propose a unique approach to significantly improving flap tolerance to ischemia by inducing a "suspended animation" like state within the flap tissue by exposure to H2S, which can bind to cytochrome c oxidase and reversibly interrupt the process of oxidative phosphorylation. If we are successful in this endeavor then we will be able to significantly reduce the morbidity associated with ischemia reperfusion injury. Furthermore, this technique of cytoprotection may be applied beyond the field of microsurgery into other medical disciplines where ischemia reperfusion injury remains a significant obstacle to progress (e.g. transplant surgery, aneurysm repair, etc.).
