Pulmonary thrombosis associated with antidiuretic hormone replacement therapy due to secondary diabetes insipidus after traumatic brain injury: A case report.

INTRODUCTION: Diabetes insipidus is a well-recognized complication of traumatic brain injury. The majority of patients with post-traumatic diabetes insipidus will require antidiuretic hormone (ADH) replacement therapy and tend to show dehydration. On the other hand, some negative effects of ADH on blood coagulation, such as increased platelet cohesion and the promotion of von Willebrand factor release, have also been reported. However, the incidence of thrombosis during antidiuretic hormone replacement therapy is disputed.

PRESENTATION OF CASE: A case of pulmonary thrombosis associated with ADH replacement therapy due to secondary diabetes insipidus after traumatic brain injury is presented here.

DISCUSSION: In our case, there were three factors that may have contributed to the observed thrombosis (dehydration, bed rest for a long period and ADH replacement therapy).

CONCLUSION: We believe that controlling urinary output and monitoring urinary and serum osmotic pressure are necessary for the management for diabetes insipidus patients after traumatic brain injury. In particular, we must carefully monitor the management of such patients during antidiuretic hormone replacement therapy.
