Ventriculoatrial (VA) shunts are used to manage hydrocephalus and idiopathic intracranial hypertension when peritoneal drainage of cerebrospinal fluid is not feasible. The technique of distal catheter placement during VA shunt insertion is controversial, especially between fluoroscopy-guided and transesophageal echocardiography (TEE)-guided techniques.

用于放置心室分流术的实时 3D 经食管超声心动图：病例系列和技术说明。

当腹腔脑脊液引流不可行时，脑室（VA）分流术可用于治疗脑积水和特发性颅内高压。VA 分流器插入期间远端导管放置技术存在争议，特别是在透视引导和经食管超声心动图 (TEE) 引导技术之间。
