The anatomy of the carotid artery at the level of the anterior clinoid process was studied in autopsy specimens and at surgery. Marking clips placed at surgery were used to correlate anatomical and angiographic findings. Removal of the anterior clinoid process permits visualization of approximately 6 mm more of the proximal internal carotid artery without entering the cavernous sinus. The exposure reaches just to the hairpin bend of the carotid siphon, but the bend is not seen. The curve in the carotid artery which is observed after anterior clinoid removal is distal to the hairpin turn and corresponds to a bend seen on the anteroposterior projection of the angiogram. Temporary occlusion of the carotid artery proximal to a paraclinoid aneurysm is possible after clinoid removal. Complications of the removal include trauma to the third nerve and cerebrospinal fluid rhinorrhea.
在尸检标本和手术中对前床突水平的颈动脉解剖结构进行了研究。手术中放置的标记夹用于关联解剖学和血管造影结果。切除前床突可使颈内动脉近端多显露约6毫米，且不进入海绵窦。显露范围刚好到达颈动脉虹吸部的发夹样弯曲处，但看不到该弯曲。切除前床突后观察到的颈动脉弯曲位于发夹样转弯的远端，与血管造影前后位投影上看到的弯曲相对应。切除前床突后，有可能在床旁动脉瘤近端临时阻断颈动脉。切除的并发症包括动眼神经损伤和脑脊液鼻漏。
