[Application of internal carotid artery stent in glomus jugular paraganglioma surgery].

To summarize the application of internal carotid artery stent in glomus jugular paraganglioma surgery, and to provide an effective strategy for reducing the risk of internal carotid artery injury. This article reviewed the surgical cases of internal carotid artery stent implanting from 2018.06 to 2022.12, and discussed the stent placement method, treatment protocols, and perioperative management strategies. A total of 5 patients underwent a comprehensive evaluation of the degree of internal carotid artery invasion using imaging techniques such as MRI, carotid CT angiography （CTA）, and digital silhouette angiography （DSA）. All patients were found to have varying degrees of internal carotid artery involvement. Stenting of the internal carotid artery was performed in all patients before surgery, and the stenting process went smoothly without any internal carotid artery injury. Three months after stenting, tumor resection or subtotal resection surgery was performed to avoid internal carotid artery injury during the surgery, and the surgical process was successfully completed. Postoperative follow-up from 4 months to 2 years showed that the internal carotid artery was patent after stent placement, with great endothelialization process and no stent-related complications. In patients with glomus jugular paraganglioma, when preoperative imaging shows internal carotid artery involvement, preoperative stenting is a safe and effective therapeutic strategy to reinforce the arterial wall structure, protect and maintain the integrity of the artery, and reduce the risk of vascular injury during the surgery. This article summarizes the experience of internal carotid artery stent in glomus jugular paraganglioma surgery, which provides an important reference for clinical practice.
