摘要: 目的 探讨视网膜中央静脉阻塞(CRVO)与静脉血栓形成危险因素之间的相关性。设计 病例对照研究。研究对象 在第四军医大学西京医院眼科就诊的268例CRVO患者组成的CRVO组及年龄匹配的267例CRVO阴性者组成的对照组。方法 对纳入研究的CRVO患者及CRVO阴性对照者行颈动脉超声多普勒检查,以明确颈动脉粥样硬化(颈动脉内有斑块或颈动脉内中膜增厚)发生状况。于晨起空腹状态下抽取CRVO患者及对照者静脉血,借助全自动免疫分析仪检测血浆同型半胱氨酸(Hcys)、维生素B12及叶酸水平。对比分析两组受试者的颈动脉粥样硬化发生率、血浆Hcys、维生素B12及叶酸水平。主要指标 颈动脉粥样硬化发生率、血浆Hcys、维生素B12及叶酸水平。结果 CRVO组268例患者中,174例(64.93%)有颈动脉粥样硬化,而267例对照组中有147例(55.06%)(P=0.017);CRVO组中,180例(51.87%) 血浆Hcys水平升高,对照组中高Hcys者为99例(37.08%),两组平均血浆Hcys水平差异显著(20.02±17.67 μmol/L vs 15.19±13.15 μmol/L,P=0.0004) ;CRVO组中,94例(35.07%)血浆维生素B12水平下降,对照组中低维生素B12者为169例(63.30%),两组平均维生素B12水平无差异(P=0.0658); CRVO组中155 例(57.79%)血浆叶酸水平降低,而对照组叶酸水平降低者有80例(29.96% ),两组平均叶酸水平差异显著(25.06±12.15 nmol/L vs 28.58±11.05 nmol/L, P=0.0005)。Logistic回归分析显示,颈动脉粥样硬化是CRVO发生的危险因素(OR=4.049,95%CI: 1.751~8.621),血中高Hcys水平 (OR=2.695,95%CI: 1.477~5.714)及低叶酸 (OR=0.354,95%CI: 0.237~0.576)也与CRVO的发生相关。结论 颈动脉粥样硬化、血中高水平的Hcys以及低叶酸与CRVO的发生密切相关,控制这些与血栓有关的危险因素可能有助于CRVO的防治。

Abstract: Objective To determine the association of risk factors related to venous thrombus with central retinal vein occlusin (CRVO). Design Case control study. Participants 268 CRVO patients (CRVO group) and  267 age matchable non-CRVO controls(control group). Methods All the participants in 2 groups were examined by carotid artery color doppler flow imaging to evaluate the incidence of atherosclerosis such as plaques of cartotid artery or increased carotid arterial intima-media thickness. Venous blood samples were drawn after all the participants fasted overnight, plasma levels of Hcys, vitamin B12 and folate were measured by automatic biochemical analyzer. The incidence of atherosclerosis in carotid artery, plasma levels of Hcys, vitamin B12 and folate were compared statistically between CRVO and control group. Main Outcome Measures Frequency of atherosclerosis in carotid artery, plasma levels of Hcys, vitamin B12, and folate. Results 174 (64.93%) of 268 patients with CRVO exhibited acarotid therosclerosis,  which was found in 147 control subjects (55.06%) (P=0.017). 180 patients (51.87%) with CRVO exhibited increased plasma levels of Hcys compared with 99 (37.08%) in  control subjects (P=0.0004). Lowered Vitamin B12 level was found in 94 patients (35.07%) with CRVO and  169(63.30%) in control subjects(P=0.0658); whereas lowered folate was found in 155 patients (57.79%) with CRVO  compared with  80 (29.96%) in control subjects (P=0.0005). Logistic regression analysis showed that carotid atherosclerosis was a risk factor for CRVO (OR=4.049, 95%CI: 1.751~8.621),whereas elevated Hcys level (OR=2.695,95%CI: 1.477~5.714) and lowered folate (OR=0.354,95%CI: 0.237~0.576) were also shown to be significant risk factors for CRVO. Conclusion Atherosclerosis in carotid artery, elevated Hcys and lowered folate were related to CRVO. Reducing above-mentioned risk factors related to thrombus may be crucial to the prevention and treatment of CRVO.
