Anesthetic Implications of Factor XI Deficiency: A Clinical Case Study and Review of Literature

Factor XI deficiency, a rare but significant coagulopathy, poses unique challenges in perioperative management, particularly in obstetric settings. This review provides an in-depth exploration of the pathophysiology, diagnosis, and anesthetic implications of factor XI deficiency, thereby emphasizing the useful role of anesthesiologists. The variable bleeding phenotype of the disorder necessitates a nuanced understanding and tailored management strategies to mitigate severe perioperative bleeding risks. Conventional coagulation tests, while useful, often fall short in predicting bleeding risks, underscoring the importance of advanced diagnostic tools, such as viscoelastic testing. Viscoelastic testing provides real-time data on clot stability, which allows for immediate intervention and more targeted therapeutic strategies compared to standard coagulation tests. A clinical case of a 25-year-old patient with factor XI deficiency undergoing emergency surgery for an ectopic pregnancy illustrates the application of viscoelastic testing in managing acute bleeding and optimizing patient outcomes and advocates for the development of standardized protocols, continuous monitoring techniques, and enhanced training programs to improve the perioperative care of patients with factor XI deficiency, providing anesthesiologists with the tools necessary to navigate the complexities of factor XI deficiency in the perioperative environment. Integrating these advanced diagnostic and therapeutic approaches could significantly improve patient safety and surgical outcomes in patients with complex coagulopathy.
