The authors present their beginning experience in the use of a new technique applied to neurosurgery: that is real-time echography. A preliminary non operative experience has first been carried on. It concerned five adults who have been studied through surgical defects. Then, eight patients, were explored intra-operatively: concerning three cerebral abscesses, one intra-cerebral haematoma, two subcortical tumors and two biopsies. In these cases, the ultrasonographic study was performed through a 3 centimeters diameter craniotomy--in case of abscess or haematoma aspiration or of biopsy--or through a classic bone flap--in case of tumor extirpation. Echography allowed an easy study of intracerebral structures and lesions. Its permits to visualize subcortical neoplasms and thus to aim them with accuracy. In the treatment of brain abscess, real time echography gives the possibility of guiding and following the progression of the probe. It, also, allows to appreciate the reduction of the suppurated cavity and thus assures a more reliable efficacity. Such a procedure indeed facilitates brain tumor biopsy; but we think that such a technique should be used only if a classic stereotactic procedure is not considered as necessary and if the mass lesion is large enough (over 1.5 cm) and not too profondly seated.
作者介绍了他们在神经外科应用一种新技术——实时超声检查的初步经验。首先进行了初步的非手术经验积累。涉及五名通过手术缺损进行研究的成年人。然后，对八名患者进行了术中探查：其中有三例脑脓肿、一例脑内血肿、两例皮质下肿瘤和两例活检。在这些病例中，超声检查通过直径3厘米的颅骨切开术进行——用于脓肿或血肿抽吸或活检的情况——或通过经典骨瓣进行——用于肿瘤切除的情况。超声检查便于对脑内结构和病变进行研究。它能够可视化皮质下肿瘤，从而准确地瞄准它们。在脑脓肿的治疗中，实时超声检查能够指导并跟踪探头的进程。它还能观察到化脓腔的缩小，从而确保更可靠的疗效。这样的操作确实便于脑肿瘤活检；但我们认为，只有在不认为经典立体定向手术有必要，且肿块病变足够大（超过1.5厘米）且位置不太深时，才应使用这种技术。
