摘　　要：目的探讨颈内动脉虹吸部钙化积分与颈内动脉起始部血管狭窄的关系。方法回顾性分析216例行颈颅动脉CT血管成像(CTA)检查的患者,计算颈内动脉虹吸部钙化积分,根据钙化积分依次分为钙化0分组、钙化1~199分组、钙化200~399分组、钙化400~599分组及钙化≥600分组。根据北美症状性颈动脉内膜切除术(NASCET)标准对颈内动脉起始部部血管狭窄分级;分析颈内动脉虹吸部钙化积分与颈内动脉起始部血管狭窄的关系。结果 216例患者432条血管中,382条血管发现虹吸部钙化,其中钙化1~199分组、200~399分组、400~599分组和≥600分组分别为70、100、112、100条。钙化1~199分组、200~399分组、400~599分组和≥600分组中发现颈内动脉起始部血管狭窄分别为18(25.7%)、78(78.0%)、106(94.6)、98(98.0%),经卡方检验分析显示,除外总钙化分数0分组与≥600分组,余各组间比较颈内动脉起始部血管狭窄的发生率与虹吸部钙化积分比较差异有统计学意义(P<0.05);钙化0分组及钙化1~199分组颈内动脉起始部血管狭窄以轻度为主;钙化200~399分组以轻~中度为主;钙化400~599分组及钙化≥600分组以重度为主(均P<0.05);同时Spearman等级相关分析显示,颈内动脉起始部血管的狭窄程度与颈内动脉虹吸钙化形态呈显著正相关(r=0.721,P<0.01)。结论颈内动脉虹吸部钙化积分分值越高,颈内动脉起始部血管狭窄的发生率越高,检测颈内动脉虹吸部钙化积分,可以作为头颈部血管狭窄性病变的有效依据。Aim To explore the correlation between the initial origin stenotic segment of internal carotid artery and calcification score at siphon segment of internal carotid artery. Methods The CTA images of 216 patients were analyzed retrospectively. Calcification score at siphon segment in internal carotid artery was calculated using agatston＇ s method, all the cases were divided into calcification 0 score group, calcification 1 ～199 score group, calcification 200N 399 score group, calcification 400-599 score group and calcification ≥600 score group. The initial origin stenotic segment of internal carotid artery was assessed based on North American Symptomatic Carotid Endarterectomy Trial. The relationship of calcification score at siphon segment of internal carotid artery were analyzed with initial origin stenotic segment of internal carotid artery. Results Two hundred and sixteen patients with 432 vascular were examined by CTA. Calcification at the siphon segment in internal carotid arteries had been found in 382. There were 70 vascular in calcification 1 - 199 score group, 100 vascular in calcification 200- 399 score group, 112 vascular in calcification 400 ～ 599 score group and 100 vascular in calcification ≥600 score group. There were 18（25.7%）, 78（78.0%）, 106（94.6）, 98（98.0%） vascular stenotic respectively in calcification 1 - 199 score group, in calcification 200- 399 score group, in calcification 400- 599 score group and in calcification ≥ 600 score group. Chi-square test statistical analysis showed that calcification score was significantly associated with initial origin stenotic segment of internal carotid artery stenotie （P〈0.05）. The initial origin stenotic segment of internal carotid artery was mild in calcification 0 score group and calcification 1 - 199 score group, mildmoderate in calcification 200-399 score group and mainly severe in calcification 400 - 599 score group and calcification ≥ 600 score group （P〈0.05） . Spearman rank correlation analysis showed that t
