The Role of Ligation in Portal Vein Trauma: A Historical Case Study.

Traumatic portal vein injuries are often fatal, with historical mortality rates as high as 71%. This report examines the 1894 assassination of French President Sadi Carnot as an early case of unsuccessful surgical management of a portal vein injury. After sustaining a stab wound to the upper abdomen, Carnot underwent emergent laparotomy but died within hours. Autopsy later revealed an unrecognized laceration of the right branch of the portal vein. This assassination deeply influenced Dr Alexis Carrel, who later developed pioneering vascular anastomosis techniques. We subsequently trace the historical evolution of portal vein trauma management to modern ligation, repair, and nonoperative strategies. Recent national trauma registry analyses demonstrate in instances where repair is not feasible, ligation may be a viable option in hemodynamically unstable patients. This case highlights the impact of single case on a century of innovation in trauma surgery.
