颈动脉支架植入术后再狭窄的研究进展

Research Progress on Restenosis after Carotid Artery Stent Implantation

摘要: 血运重建是颈动脉狭窄患者预防缺血性卒中的有效策略。颈动脉支架植入术是颈动脉内膜切除术的一种安全替代方法，尤其对于手术高危患者。然而，支架内再狭窄增加了复发性缺血性卒中的风险，限制了介入治疗的益处，并对患者构成了显著威胁。颈部血管超声、CT血管造影、数字减影血管造影可用于检测支架植入术后再狭窄，各有优缺点。再狭窄患者需要再干预治疗时，可提供不同的治疗方案，如球囊成形术、重复支架植入等，但最佳治疗策略尚未明确。因此，研究颈动脉支架植入术术后再狭窄，对提高颈动脉支架植入术的长期疗效至关重要。

Abstract: Revascularization is an effective strategy for preventing ischemic stroke in patients with carotid artery stenosis. Carotid artery stent implantation is a safe alternative to carotid endarterectomy, especially for high-risk patients undergoing surgery. However, stent restenosis increases the risk of recurrent ischemic stroke, limits the benefits of interventional treatment, and poses a significant threat to patients. Cervical vascular ultrasound, CT angiography, and digital subtraction angiography can be used to detect restenosis after stent implantation, each with its own advantages and disadvantages. When patients with restenosis need further intervention treatment, different treatment options can be provided, such as balloon angioplasty, repeated stent implantation, etc., but the optimal treatment strategy is not yet clear. Therefore, studying restenosis after carotid artery stent implantation is crucial for improving the long-term efficacy of carotid artery stent implantation.
