摘要
目的分析68例胃癌患者术前进行腹部多层螺旋CT血管成像(Mu ltislice Sp iral CT Angiog-raphy,MSCTA)检查的结果,探讨该检查在胃癌根治术前后显示供胃动脉解剖的诊断符合率及临床意义。方法采用GE64排L ightSpeed VCT,对68例患者进行MSCTA检查,显示供胃动脉、肿瘤血供以及肿瘤与血管的关系,并与手术结果进行对照。结果 经MSCTA检查,发现68例患者中供胃血管正常的有62例(91.2%),解剖发生变异的有6例(8.8%)。全部患者于胃癌根治治疗中顺利完成了手术,术后发现供胃血管正常的只有61例(89.7%),解剖发生变异的有7例(10.3%)。其术后的诊断符合率为98.5%(67/68)。结论 MSCTA检查在显示供胃动脉解剖和变异上有较高的符合率,通过对患者术前进行MSCTA检查,用以正确评估肿瘤血管及周围组织结构的信息,有利于对胃癌进行定位及分期诊断,对手术方案的选择、制订以及患者的处理有重要影响。这对提高转移淋巴结的清扫率;防止因缺乏了解而误伤变异血管及误伤某些组织或器官提供了保障;有利于缩短手术时间,减少手术并发症,增加手术的安全和准确性,对指导手术的顺利完成,提高患者的根治水平有着重要的临床意义。
Objective To explore the clinical significance of preoperative abdominal Multislice Spiral CT Angiography（MSCTA） and its diagnostic accordance rate of the gastric blood supplying vessels in sixty-eight patients with gastric cancer.Methords MSCTA was taken in sixty-eight patients with gastric cancer with LightSpeed VCT（USA,GE64-rows） to show gastric blood supplying vessels,cancer blood supplying vessels and the relationship between cancer and the vessels.The result of MSCTA was compared with what was shown during operation.Results Sixty-two（91.2%）cases with normal gastric blood supplying vessels and six cases（8.8%）with variation in the gastric blood supplying vessels were demonstrated by MSCTA.All the patients underwent radical operation of gastric cancer successfully.However,sixty-one cases with normal gastric supplying vessels and seven cases with gastric supplying vessels variation were discovered during the operation.The diagnostic accordance rate was 98.5%（67/68）.Conclusion There was high diagnostic accordance rate in MSCTA to show gastric supplying vessel and its variation.Preoperative MSCTA can be used to evaluate cancer vessels and the adjacent tissues,benefits to locate gastric cancer and define its stage.It has important impact on operation protocol and the treatment of the patients.It can also benefit to increase the dissection rate of lymph node metastasis,avoid incidental injury of variant vessels and the adjacent tissues or organs,shorten the operative time,reduce the complications and improve the operative accuracy and security.It has great clinical significance in guiding and improving the radical operation.
