Ventral wall ICA aneurysms are a type of Paraclinoid aneurysms which arise from ventral surface of ICA opposite to the origin of the ophthalmic artery. These are technically challenging owing to its close proximity to the anterior clinoid process, difficulty in getting proximal control, difficulty in preserving ophthalmic artery and maintaining the patency of ICA.
A 38 year old patient with a Ventral wall ICA aneurysm by Dolenc approach.
Tailored dural peeling and extradural anterior clinoidectomy exposes proximal part of Paraclinoid ICA allowing better proximal control and a wider exposure, which is crucial for clipping these aneurysms.
颈内动脉腹侧壁动脉瘤是一种位于颈内动脉腹侧面、眼动脉起点对侧的眶尖动脉瘤。由于其与前床突毗邻，近端控制困难，保护眼动脉和保持颈内动脉通畅困难，因此具有一定的技术挑战性。
采用 Dolenc 入路对 1 例颈内动脉腹侧壁动脉瘤患者进行手术。
个体化的硬脑膜剥离和硬膜外前床突切除术暴露了眶尖颈内动脉的近端部分，有助于更好地进行近端控制和更广泛的显露，这对于夹闭这些动脉瘤至关重要。
