Flap Ischemia–Reperfusion Injury

Ischemia–Reperfusion Injury in Flap Surgery provides a clinically oriented and evidence-based synthesis of one of the most persistent challenges affecting flap survival and postoperative outcomes. Grounded in more than fifteen years of continuous experimental research, the book integrates mechanistic understanding, validated flap models, and translational principles to offer a coherent framework for addressing ischemia–reperfusion (I/R) injury across plastic and reconstructive surgery. The text begins by establishing I/R injury as a central determinant of complications in free flaps, pedicled flaps, replantation, and composite tissue transfer, before outlining the cellular and microvascular mechanisms—oxidative stress, endothelial dysfunction, inflammation, micro-thrombosis, and the no-reflow phenomenon—that shape clinical outcomes. It then examines the translational relevance of dorsal skin, epigastric island, and muscle flap models and clarifies how findings from these systems should inform surgical interpretation. A detailed discussion of injury assessment methods—including viability testing, necrosis quantification, histopathology, and oxidative stress markers—highlights the need for greater standardization in reporting. The book then evaluates a wide range of protective strategies, with particular emphasis on pharmacologic agents such as melatonin, taurine, ceruloplasmin, trimetazidine, edaravone, lutein, and propionyl-L-carnitine. Complementary approaches—including ischemic preconditioning, postconditioning, and mechanical conditioning protocols—are presented with attention to mechanism, evidence, and feasibility in microsurgical workflows. Additional chapters explore perioperative factors such as anesthetic management, hemodynamic stability, thermal control, and antithrombotic approaches that modulate I/R severity. Linking experimental evidence with clinical practice, the book translates research findings into actionable pathways for flap surgery and identifies persistent limitations in the literature that hinder robust evidence synthesis. Practical algorithms and recommendations guide surgeons in minimizing I/R-related complications, while the concluding section outlines future directions and advocates for harmonized scoring systems and standardized reporting to accelerate clinical translation. Combining methodological continuity with a strong clinical focus, Ischemia–Reperfusion Injury in Flap Surgery will be an essential resource for plastic and reconstructive surgeons, microsurgeons, researchers in experimental flap physiology, and trainees seeking to improve outcomes through a deeper understanding of I/R injury.
