摘要
本文报告经脉络裂入路处理三脑室病变8例,并介绍了手术方法。该入路的优点在于:①脉络裂系侧脑室壁最薄弱的部位,经此甚易进入三脑室;②不切断穹窿,术后无记忆缺失之虞;③显露好,特别适用于三脑室中部,也适用于三脑室前部或后部病变。作者认为,对三脑室前中部病变,可分别通过脉络裂和室间孔这一“8”字形入路处理,而无需将二者之间的室间孔后缘切开,从而避免了结扎切断丘纹静脉可能带来的不良后果。
Eight patients with third ventricular lesions were treated using transchoroidal approach. The operative technique was described. The advantages of this approach are: (1)easy entering into the third ventricle through the choroidal fissure, the thinnest site in the wall of the lateral ventricle (2)avoiding memory dysfunction because of access to the third ventricle by displacing, rather th- an dividing, the fornix, and (3) excellent exposure. Transchoroidal approach is most suited to mid-third ventricular lesions. It's also suited to lesions in the anterior or posterior portion of the third ventricle. The authors pointed out that it is not really needed to sacrifice the thalamostriate vein and open the posterior margin of the foramen of Monro in order to manage the lesions located in the anterior and middle portions of the third ventricle. In fact these lesions can be approached through both the choroidal fissure and the foramen of Monro along an 8-shaped opening.
