The goal of this study was to determine whether carotid angioplasty and stenting (CAS) is equivalent to carotid endarterectomy (CEA) in patients with symptomatic carotid stenosis >70% by a randomized, controlled trial in a community hospital.
Carotid angioplasty and stenting has been suggested to be as effective as CEA for treatment of symptomatic carotid artery stenosis.
A total of 104 patients presenting with cerebrovascular ischemia ipsilateral to carotid stenosis were selected randomly for CEA or carotid stenting and followed for two years.
Stenosis decreased to an average of 5% after CAS. The patency of the reconstructed artery remained satisfactory regardless of the technique as determined by sequential ultrasound. One death occurred in the CEA group (1/51); one transient ischemic attack occurred in the CAS group (1/53); no individual sustained a stroke. The perception of procedurally related pain/discomfort was similar. Hospital stay was similar, although the CAS group tended to be discharged earlier (mean = 1.8 days vs. 2.7 days). Complications associated with CAS prolonged hospitalization when compared with those sustaining a CEA-related complication (mean = 5.6 days vs. 3.8 days). Return to full activity was achieved within one week by 80% of the CAS group and 67% of the patients receiving CEA. Hospital charges were slightly higher for CAS.
Carotid stenting is equivalent to CEA in reducing carotid stenosis without increased risk for major complications of death/stroke. Because of shortened hospitalization and convalescence, CAS challenges CEA as the preferred treatment of symptomatic carotid stenosis if a reduction in costs can be achieved.
本研究的目的是通过在一家社区医院进行的随机对照试验,确定对于症状性颈动脉狭窄>70%的患者,颈动脉血管成形术和支架置入术(CAS)是否等同于颈动脉内膜切除术(CEA)。
对于症状性颈动脉狭窄的治疗,有人提出颈动脉血管成形术和支架置入术与CEA一样有效。
总共104例出现与颈动脉狭窄同侧脑血管缺血的患者被随机选择接受CEA或颈动脉支架置入术,并随访两年。
CAS术后狭窄平均降至5%。通过连续超声检查确定,无论采用何种技术,重建动脉的通畅性均保持良好。CEA组发生1例死亡(1/51);CAS组发生1例短暂性脑缺血发作(1/53);无个体发生卒中。与手术相关的疼痛/不适的感受相似。住院时间相似,尽管CAS组倾向于更早出院(平均1.8天对2.7天)。与发生CEA相关并发症的患者相比,与CAS相关的并发症延长了住院时间(平均5.6天对3.8天)。CAS组80%的患者和接受CEA的患者中有67%在一周内恢复到完全活动状态。CAS的医院收费略高。
颈动脉支架置入术在降低颈动脉狭窄方面等同于CEA,且不会增加死亡/卒中的主要并发症风险。由于住院和康复时间缩短,如果能够降低成本,CAS对CEA作为症状性颈动脉狭窄的首选治疗方法构成了挑战。
