目的探讨64层螺旋CT对急性主动脉综合征的诊断及腔内支架隔绝术后随访的价值。方法选择急性主动脉综合征患者59例,其中男性48例,女性11例;年龄32~85岁,平均年龄57.29岁。所有患者行CT平扫及增强扫描,原始数据在工作站上进行后处理,分析其CT表现。其中20例行腔内支架隔绝术并复查,均行CT平扫及增强扫描。结果 59例患者中,主动脉夹层40例,真假双腔及剥离内膜片均可显示,36例可见破裂口;未见明显破口的主动脉壁间血肿8例,合并壁间血肿的主动脉穿透性溃疡7例;主动脉瘤破裂4例,位于主动脉弓2例,位于降主动脉2例。20例患者术后支架通畅,未出现内漏、支架移位、血栓形成等并发症。结论 64层螺旋CT平扫及增强扫描是一种无创、快速的检查方法,对急性主动脉综合征具有较高的诊断及腔内支架隔绝术后的随访价值。 Objective To investigate the value of 64-slice spiral CT in the diagnosis of acute aortic syndrome and follow-up after endovascular stent-graft. Methods A total of 59 patients with acute aortic syndrome were selected, including 48 males and 11 females. The patients ranged in age from 32 to 85 years with a mean age of 57.29 years. All patients underwent CT scan and enhanced scan, the original data were post-processed on the workstation to analyze the CT performance. Among them, 20 cases underwent endovascular stent ablation and were reviewed. Both CT scan and enhanced scan were performed. Results Of the 59 patients, 40 cases of aortic dissection, true and false double-lumen and exfoliated intima showed that 36 cases were found to have ruptured mouth. There were 8 cases of aortic intermural hematoma without obvious break, Aortic penetrating ulcer in 7 cases; ruptured aortic aneurysm in 4 cases, located in the aortic arch in 2 cases, located in the descending aorta in 2 cases. Twenty patients had unobstructed stents, no internal leakage, stent displacement, thrombosis and other complications. Conclusion 64-slice spiral CT scan and contrast-enhanced scan are noninvasive and rapid examination methods. They have high diagnostic value and follow-up value after endovascular stent-graft in patients with acute aortic syndrome.
