Intraventricular chemotherapy via Ommaya reservoir is an important part of the treatment in patients with malignant central nervous system tumors. In these patients, catheter placement can be challenging due to the normal-sized ventricles.
Intraoperative ultrasound guidance was used for Ommaya reservoir placement in a 56-year-old patient with multiple intracranial and leptomeningeal metastases who had cavum septum pellucidum et vergae malformation. The catheter was successfully placed into the frontal horn of the lateral ventricle outside the cavum.
Intraoperative ultrasound is a suitable image guidance system in patients with slit-like or normal-sized ventricles. It can also be used in patients with ventricular malformations.
通过 Ommaya 储液器进行脑室内化疗是治疗恶性中枢神经系统肿瘤患者的重要组成部分。在这些患者中，由于正常大小的脑室，导管放置可能具有挑战性。
在一名 56 岁的患者中，使用术中超声引导进行 Ommaya 储液器放置，该患者患有透明隔腔和脑底池发育不良伴多发颅内和软脑膜转移。导管成功地置于侧脑室腔外的额角。
对于裂隙状或正常大小的脑室患者，术中超声是一种合适的图像引导系统。它也可以用于脑室畸形的患者。
