Electroconvulsive Therapy While Receiving OralAnticoagulation for Deep Venous Thrombosis:Report on Eight Cases and a Review of theLiterature.

BACKGROUND: Electroconvulsive therapy (ECT) is indicated for critical psychiatric conditions, which themselves constitute a risk for deep venous thrombosis (DVT) owing to prolonged immobility, dehydration, and venous stasis.

OBJECTIVE: We describe challenging instances of ECT implementation while taking direct oral anticoagulants (DOACs).

METHOD: We report on 8 patients receiving DOACs for DVT who were successfully treated with ECT at the University of Yamanashi Hospital. We also provide a literature review on this topic.

RESULTS: There were 6 female patients (the average age was 60.9+/-13.4 y.o.) and diagnoses included major depression, bipolar depression and schizophrenia. DOACs were edoxaban for 4 patients, rivaroxaban for 2, and apixaban for 2. A total of 92 ECT sessions were cautiously and safely completed in collaboration with multidisciplinary medical professionals without problematic adverse events, such as bleeding. A literature search found one case series of warfarin but currently available evidence is confined to sporadic case reports regarding ECT and DOACs for DVT. These reports were represented by successful implementation of ECT to patients receiving treatment with anticoagulants for DVT or thromboembolism. Ours is the first of a successful treatment with ECT while taking apixaban or edoxaban.

CONCLUSION: A clinical dilemma is that ECT is indicated for critical conditions that are likely to predispose patients to developing DVT. Paucity of data clearly highlights the need for more studies to support a contention that ECT, when carefully performed in consultation with other medical experts, is a viable treatment for those with DVT receiving oral anticoagulants.
