矢状窦旁和胼胝体动静脉畸形(AVM)很多作者采用患侧入路,Yasargil 认为病变常偏向一侧,应从患侧入路,并根据脑血管造影来决定。Drake 则选择非优势半球或受累最大的一侧作大脑半球间大脑镰旁入路。Malis 提出双侧开颅并将硬脑膜翻向上矢状窦,在使用自动牵开器的条件下,逆行分离进入上矢状窦的静脉,据称对保护大脑前动脉较易,本文作者和上述作者意见相反,采用病变对侧手术入路,对两例矢状窦旁 AVM 进行手术,效果满意。
The parasagittal and corpus callosum AVMs Many authors use the ipsilateral approach, and Yasargil believes that the lesions tend to be biased on one side and should be approached from the affected side and determined on the basis of cerebral angiography. Drake chose the non-dominant hemisphere or the most affected side as the falx parasite hemisphere approach. Malis proposed a bilateral craniotomy and turned the dura towards the superior sagittal sinus, retrogradely separating the veins into the superior sagittal sinus with the use of an automatic retractor, purportedly to protect the anterior cerebral artery more easily, The author’s opinion, the opposite side of the lesion surgery approach, two cases of sagittal sinus AVM surgery, the effect is satisfactory.
