In a remarkable case report published in the April 2019 issue of “No Shinkei Geka” (Neurological Surgery), Japanese neurosurgeons detail the successful treatment of a patient suffering from spontaneous intracranial hypotension via repetitive epidural blood patches after reversing the effects of warfarin. This medical narrative is not only a showcase of multidisciplinary treatment but also sets a precedent for managing similar conditions in patients on anticoagulant therapy. Here’s an in-depth look at the case, its implications for future treatments, and insights into spontaneous intracranial hypotension (SIH) management.
Patient Background and Clinical Presentation
A 75-year-old male patient presented with a perplexing case of a persistent headache that had been plaguing him for two weeks. His medical history was significant for atrial fibrillation, a heart rhythm irregularity for which he was on warfarin, an anticoagulant medication. Upon neurological examination upon admission, he showed signs of mild disorientation, raising concerns among the medical team.
Initial diagnostic imaging, including magnetic resonance images (MRI) of the brain, detected bilateral subdural hematomas, a worrying distortion of the midbrain, and diffused pachymeningeal enhancement indicative of fluid leakage. Despite the initiation of conservative treatments, including bed rest and hydration, the patient’s condition deteriorated, leading to an emergent therapeutic intervention.
The Treatment Dilemma and Intervention
Conservative treatment options provided little relief, and by the third day of his hospital stay, the patient’s lethargy intensified. In an urgent course of action, an epidural blood patch (EBP) at the lumbar level was performed. EBP is a procedure where a small amount of the patient’s own blood is injected into the epidural space of the spine, creating a clot to seal any leak. Although the patient’s consciousness improved immediately post-procedure, the relief was fleeting and lasted only 12 hours.
This pattern continued with the second EBP, leading the medical team to the pivotal decision: reversal of the warfarin effect before the third EBP. This was achieved with the administration of vitamin K and fresh frozen plasma, crucial for normalizing coagulability and allowing the blood patch to be effective. Following the reversal and the third EBP, the patient’s alertness dramatically improved, and he remained stable.
Pursuing a Stable Clinical Course
Notably, despite neurological stabilization, imaging revealed progressively increasing subdural hematomas first on the left and then on the right side. These developments necessitated further EBPs and surgical evacuations of the hematomas. It was only after the fifth EBP that the patient’s clinical course became free of events, paving the way for recovery.
The Significance of Warfarin Reversal in SIH Treatment
This case is significant as it highlights the complex interplay between anticoagulant therapy and EBP effectiveness. Warfarin, being a potent anticoagulant, can exacerbate hematoma formation or contribute to poor clotting during EBP procedures. Hence, the reversal of warfarin was a game-changer for ensuring the success of the EBPs performed on the patient.
Study Implications and Future Directions
The case report, bearing the DOI 10.11477/mf.1436203959, contains critical insights for medical professionals, indicating that in certain scenarios, normalization of coagulability is required for a successful EBP. Here are the implications of the study:
1. Assessment of Coagulation Status: Medical practitioners should consider anticoagulation status when dealing with SIH patients, especially those undergoing anticoagulant therapy.
2. Conservative Management Precedence: Treatment protocol may start with conservative measures but should not delay EBP when indicated.
3. Repetitive EBP: Multiple EBPs may be necessary, and their efficacy should be assessed in conjunction with coagulation status.
4. Patient Monitoring: Regular imaging can be valuable in monitoring the progression of hematoma and the necessity for further procedures.
5. Holistic Approach: The intertwining of neurosurgery with hematologic stabilization underpins a multidisciplinary approach in the management of SIH.

The case offers fresh insights into the management of SIH, especially in patients who are concurrently on anticoagulant therapy. While predictors for successful EBP have yet to be fully clarified, this case opens the door for further research and a better understanding of SIH treatment protocols. It is a reminder of the ever-evolving nature of medical practice and the need for adaptability and attentiveness to the specifics of individual patient cases. This study’s narrative reinforces the intricacies of patient care and highlights the collaboration between neurosurgical and hematological disciplines in treating complex conditions.
