We describe our clinical experience with the use of indocyanine green (ICG) videoangiography to delineate the locations of the cortical draining veins before dural opening in 3 cases of parasagittal lesions. With this technique, the veins are marked through the dura, and then the dura can be opened precisely to avoid cortical venous injury.
To demonstrate in a clinical series the adjunct use of intraoperative ICG angiography to optimize the dural opening for parasagittal lesions.
We describe 3 cases of parasagittal lesions, 2 meningiomas, and 1 arteriovenous malformation treated using the described technique.
Once the dura had been exposed, ICG at a dose of 0.25 mg/kg was injected into the patient's peripheral vein as a bolus. When the dye reached the illuminated field of interest, ICG fluorescence was induced by the use of a light source with a wave-length ICG absorption band. Thereafter, the dural cortical veins were marked through the dura and precisely opened, avoiding cortical venous injury.
Indocyanine green video angiography is a safe, fast, inexpensive, and accurate investigation that allows the surgeon to strategically plan and protect important parasagittal dural venous drainage during craniotomy.
我们描述了在 3 例矢状旁病变中使用吲哚菁绿（ICG）视频血管造影术在硬脑膜切开前描绘皮质引流静脉位置的临床经验。通过该技术，可通过硬脑膜标记静脉，然后可以精确地打开硬脑膜，以避免皮质静脉损伤。
在临床系列中展示术中吲哚菁绿血管造影术在优化矢状旁病变硬脑膜切开中的辅助作用。
我们描述了 3 例矢状旁病变，2 例脑膜瘤和 1 例动静脉畸形，采用所述技术进行治疗。
一旦暴露硬脑膜，就以 0.25mg/kg 的剂量将 ICG 作为弹丸注入患者外周静脉。当染料到达感兴趣的照明区域时，使用具有 ICG 吸收带的波长的光源来诱导 ICG 荧光。此后，通过硬脑膜标记皮质静脉，并精确地打开硬脑膜，避免皮质静脉损伤。
吲哚菁绿视频血管造影术是一种安全、快速、经济且准确的检查方法，可使外科医生在开颅手术期间战略性地规划和保护重要的矢状旁硬脑膜静脉引流。
