Thromboelastography with platelet mapping to guide anesthetic management of emergency cesarean delivery in a patient with thrombasthenia: a case report.

Background: Perinatal management of congenital platelet dysfunction represents a challenge. One of the major concerns is whether neuraxial anesthesia can be applicable for cesarean delivery. We present a patient with thrombasthenia who underwent emergency cesarean delivery.

Case Presentation: A 34-year-old primipara was diagnosed with autosomal dominant thrombasthenia, which was not classified as any known type. A thorough examination revealed that adenosine diphosphate aggregation and collagen aggregation were suppressed. Platelet mapping of viscoelastic testing was used to observe the trajectory of platelet function during pregnancy, which was found to be normal to hypercoagulable until 38 weeks of gestation. On the basis of the results of testing and physiological status, we commenced spinal anesthesia and avoided prophylactic platelet transfusion.

Conclusion: The platelet mapping of viscoelastic testing was rapid and simple, allowing repeated examinations. We could choose the appropriate anesthesia method and determine the necessity of blood transfusion for a pregnant patient with thrombasthenia.
