Objective: To explore the minimally invasive techniques and outcome of carotid ophthalmic artery aneurysms clipping via a frontolateral approach. Methods: The clinical data of 95 patients with carotid ophthalmic artery aneurysms treated via frontolateral approach in the last 1.5 years in Beijing Tiantan Hospital and Beijing Anzhen Hospital were analyzed retrospectively.Before the operation, digital subtraction angiogram (DSA) was performed among all patients.The patients were divided into two groups by the lateral approach.According to preoperative classification, surgical characteristics and prognosis were summarized. Results: Ninety-five cases of ophthalmic aneurysms were divided into type Ⅰ of 44 cases (46.3%), type Ⅱ of 34 cases (35.7%) and type Ⅲ of 17cases (17.9%), according to the results of DSA.The diameter of aneurysm was <10 mm (35 cases), 10-25 mm (34 cases), and >25 mm (26 cases). In the 17 cases of subarachnoid hemorrhage (SAH), 8 cases were ruptured carotid-ophthalmic artery aneurysms.Among those 95 patients, 93 were clipped successfully, 2 was trapped.Multiple aneurysms in 5 cases were treated in one surgical session through the same approach.No aneurysm residual was found after postoperative CTA review.Ipsilateral vision of 3 cases were decline.Cerebral infarction was appeared in 9 cases.All the others had a good recovery. Conclusions: The carotid-ophthalmic artery aneurysms could be well exposed. Microsurgery through frontolateral approach has the advantages such as minimal invasion, less effect on the patients' look and simple procedure.The frontolateral approach is safe and effective in surgery for ophthalmic segment of the internal carotid artery aneurysms.
