Electroconvulsive Therapy in Thrombocytopenic Patients: A Case Report and Literature Review

Abstract

AbstractIntroductionElectroconvulsive therapy (ECT) continues to be one of the most effective treatments for severe and treatment-resistant major depression. Although there are no absolute contraindications to performing ECT, the risks and benefits need to be assessed in all patients. We present a patient with a history of paroxysmal nocturnal hemoglobinuria (PNH) with significant thrombocytopenia, who completed an index course of six ECT sessions without complication. Currently, there are only two published case reports which describe the use of ECT in patients with thrombocytopenia.MethodsAD is a 37-year-old female with a history significant for MDD, GAD, panic disorder, PNH, and Budd Chiari, who presented to ED for suicidal ideation. Initial labs showed pancytopenia (Hb 4.56 mg/dl, Absolute Neutrophil 0.7 x 103/mL). Given her history of multiple failed SSRIs, ECT was proposed to treat her depression. Anesthesia delayed her initial pre-operative assessment due to concerns regarding her platelet count and risk of bleeding. They recommended transfusion with a preprocedural platelet count goal of 50 x 103/mL. Psychiatry recommended a platelet goal of 20 x 103/mL given previous ECT literature. Patient underwent six ECT sessions without complications. Her platelets ranged from 24–40 x 103/mL and she did not require preprocedural platelet transfusion.ResultsDue to a lack of published literature, there are no formal guidelines for performing ECT in thrombocytopenic patients. The first case report details a 64-year-old female who underwent 12 ECT sessions without complication, while her platelet count ranged from 7–38 x 103/mL. The most recent case report describes a 74-year-old male who underwent nine ECT treatments without complications. The authors decided to transfuse prophylactically if pre-procedure platelet count was less than 20 x 103/mL. The patient underwent nine treatments, requiring eight transfusions. CT head did not show any signs of hemorrhage or structural changes. The authors remarked it is unclear whether the transfusions were necessary.ConclusionsEven though ECT has been in use for over 80 years, there is still much that is unknown about this treatment modality. This case highlights the lack of absolute contraindications to performing ECT. However, the lack of literature and studies regarding platelet goals in thrombocytopenic patients for ECT delayed patient care in this specific case. We add a third case report in a thrombocytopenic patient who underwent ECT without complications with a pre-procedure transfusion criterion if platelet count was less than 20 x 103/mL. More research needs to be conducted to determine risk and cut-off limits for platelet transfusion prior to performing ECT in thrombocytopenic patients.FundingNo funding
