脑室Ommaya囊置入术联合抗凝治疗重症颅内静脉窦血栓形成1例报道A Case Report of Ventricular Ommaya Reservoir Placement Combined with Anticoagulation Therapy for Severe Cerebral Venous Sinus Thrombosis

颅内静脉窦血栓形成（cerebral venous sinus thrombosis，CVST）是一种特殊类型的脑血管疾病。重症CVST以广泛静脉窦血栓、严重高颅压及继发性脑损伤为主要特征，其采用单纯抗凝治疗效果有限，常需外科干预。本文报道1例重症CVST患者，在抗凝治疗时间不足、病情进展为高颅压危象后，采用脑室Ommaya囊置入术行过渡治疗，为抗凝治疗争取了时间并成功逆转病情，为重症CVST微创干预策略的探索提供了实践参考。Cerebral venous sinus thrombosis (CVST) is a special type of cerebrovascular disease. Severe CVST is characterized by extensive venous sinus thrombosis, significant intracranial hypertension, and secondary brain injury. Anticoagulation therapy alone yields limited efficacy in severe cases, often necessitating surgical intervention. This article reports a case of severe CVST in which the patient developed an intracranial hypertension crisis due to an insufficient duration of anticoagulation therapy, and was subsequently treated with ventricular Ommaya reservoir placement as a bridging treatment. This intervention secured a therapeutic time window for anticoagulation therapy, ultimately achieving a successful reversal of the patient’s condition. This case provides a practical reference for the exploration of minimally invasive intervention strategies for severe CVST.
