简介：AbstractBackground:Imprecise interpretation of coronary angiograms was reported and resulted in inappropriate revascularization. Synergy Between Percutaneous Coronary Intervention with Taxus and Cardiac Surgery (SYNTAX) score is a comprehensive system to evaluate the complexity of the overall lesions. We hypothesized that a real-time SYNTAX score feedback from image analysts may rectify the mis-estimation and improve revascularization appropriateness in patients with stable coronary artery disease (CAD).Methods:In this single-center, historical control study, patients with stable CAD with coronary lesion stenosis ≥50% were consecutively recruited. During the control period, SYNTAX scores were calculated by treating cardiologists. During the intervention period, SYNTAX scores were calculated by image analysts immediately after coronary angiography and were provided to cardiologists in real-time to aid decision-making. The primary outcome was revascularization deemed inappropriate by Chinese appropriate use criteria for coronary revascularization.Results:A total of 3245 patients were enrolled and assigned to the control group (08/2016-03/2017, n = 1525) or the intervention group (03/2017-09/2017, n= 1720). For SYNTAX score tertiles, 17.9% patients were overestimated and 4.3% were underestimated by cardiologists in the control group. After adjustment, inappropriate revascularization significantly decreased in the intervention group compared with the control group (adjusted odds ratio [OR]: 0.83; 95% confidence interval [CI]: 0.73-0.95; P = 0.007). Both inappropriate percutaneous coronary intervention (adjusted OR: 0.82; 95% CI: 0.74-0.92; P < 0.001) and percutaneous coronary intervention utilization (adjusted OR: 0.88; 95% CI: 0.79-0.98; P = 0.016) decreased significantly in the intervention group. There was no significant difference in 1-year adverse cardiac events between the control group and the intervention group.Conclusions:Real-time SYNTAX score feedback significantly reduced inappropriate coronary revascularization in stable patients with CAD.Clinical trial registration:Nos.

简介：摘要目的探讨交叉MIS-TLIF联合经皮椎弓根螺钉治疗邻近双节段腰椎管狭窄伴节段失稳症患者的临床疗效。方法选择腰椎管狭窄伴节段失稳症的患者79例，按入院先后顺序编号，按随机数分配表分为交叉MIS-TLIF联合经皮椎弓根螺钉治疗组（交叉组）48例、双侧传统MIS-TLIF治疗组（双侧组）31例，比较两组手术时间、术中出血量、术后引流量、住院时间。通过比较两组术前及术后3 d、7 d、3个月及末次随访时的腰痛视觉模拟（VAS）评分、术后1、3、6个月及末次随访时ODI指数、椎间融合率、临近节段退变率，来评估临床疗效。结果交叉组的手术时间、术中出血量、术后引流量明显少于双侧组，差异有统计学意义（均P<0.05）；两组术后住院时间相当，差异无统计学意义。两组术前及术后3 d、7 d、3个月及末次随访时的腰痛VAS评分显著优于术前（P<0.01），术后3 d、7 d交叉组明显优于双侧组（P<0.05），术后3个月及末次随访时差异无统计学意义。两组术前及术后1、3、6个月及末次随访时ODI指数均明显优于术前（P<0.01），两组间比较差异无统计学意义，末次随访时椎间融合率、临近节段退变率，组间比较差异无统计学意义（P>0.05）。结论交叉MIS-TLIF联合经皮椎弓根螺钉治疗邻近双节段腰椎管狭窄伴节段失稳症患者，对腰椎后方复合体等解剖结构破坏少，术中及术后出血相对较少，两组间椎间融合率、临近节段退变率相当，同时避免了传统双侧MIS-TLIF置钉及安装纵棒的困难，简化手术操作，术后恢复快，手术效果显著。
