Some intracranial aneurysms that might be considered inoperable by open craniotomy are readily treatable by stereotaxic thrombosis. This is possible because the stereotaxic technique requires only that some point on the fundus of the aneurysm can be punctured with a needle. Illustrative cases are given describing the successful treatment of aneurysms arising at the origin of the ophthalmic artery, within the cavernous sinus, within the sella turcica, and from the vertebrobasilar and the posterior inferior cerebellar arteries ventral to the brain stem. The aneurysms within the sella or cavernous sinus can be approached through the sphenoid sinus, and the aneurysms ventral to the brain stem can be approached through the clivus without opening the dura.
一些通过开颅手术可能被认为无法手术治疗的颅内动脉瘤，采用立体定向血栓形成术很容易治疗。这之所以可行，是因为立体定向技术只要求能用针穿刺到动脉瘤底部的某个点。文中给出了一些说明性病例，描述了起源于眼动脉起始部、海绵窦内、蝶鞍内以及脑干腹侧椎动脉和小脑后下动脉的动脉瘤的成功治疗。蝶鞍或海绵窦内的动脉瘤可通过蝶窦进行处理，脑干腹侧的动脉瘤可通过斜坡进行处理，而无需打开硬脑膜。
