[Preliminary application of one-step hybrid operation in the treatment of carotid artery occlusion].

Objective: To evaluate the prognosis and surgical complication of the recanalization treatments for internal carotid artery (ICA) occlusion by using one-step hybrid carotid endarterectomy and endovascular surgery. Methods: Retrospective analysis was performed on the clinical data and follow-up data of 22 patients with occluded ICA treated by one-step hybrid surgery. Difference in Barthel score and occurrence of ischemic stroke were compared with surgical group and conventional group which was treated by oral taking anti-platelet drugs. Further, the complications were analyzed to evaluate the safety and effectiveness of the surgery. Results: The difference in ischemic event rate and Barthel scores improvement between the two groups were significant. Occlusive ICAs in 19 cases were recanalized successfully. The possibility of brain hyperperfusion related to the surgery was 10.5% (2/19) while the possibility of carotid artery cavernous fistula was 9.1% (2/22). We also observed rare dissecting ICA caused by the treatment (4.5%) and distal restenosis (5.3%). Conclusions: One-step hybrid carotid endarterectomy and endovascular surgery could help recanalize the ICA, improve the blood supply and improve the prognosis. It's a safe and effective treatment for ICA occlusion.
