However, mitigating prolonged warm ischemia during the extensive tumor resection poses a significant challenge to flap viability. Presented herein is a case illustrating the novel use of temporary intraoperative vascular shunting to overcome this limitation. During hemipelvectomy for a 17.7\u2009\u00d7\u200916.9\u2009\u00d7\u200919.3\u2009cm osteosarcoma of the proximal left femur in a 74\u2010year\u2010old man, unplanned early ischemia of the lower extremity was addressed by placing carotid shunts between the external iliac and popliteal vessels. The technique maintained continuous perfusion to the future flap for 4\u2009h during the concurrent pelvic resection and fillet flap harvest. Definitive microvascular anastomosis was performed subsequently and the 37\u2009\u00d7\u200931\u2009cm flap remained viable postoperatively for the 3\u2009months of follow\u2010up. This case report reintroduces temporary shunting as a simple, effective, and readily available technique to preserve flap perfusion in complex microsurgical reconstructions, mirroring damage\u2010control principles from trauma surgery.<\/jats:p>","DOI":"10.1002\/micr.70254","type":"journal-article","created":{"date-parts":[[2026,6,6]],"date-time":"2026-06-06T08:07:40Z","timestamp":1780733260000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Temporary
