目的:探讨不明原因消化道出血数字减影血管造影检查(DSA)与介入治疗的方法及临床效果。方法:选择68例不明原因消化道出血患者行DSA检查(观察组),检查造影剂外溢、病理血管和肿瘤染色,从而确定出血原因及部位,对出血部位采用超选择动脉插管灌注垂体后叶素止血或明胶海绵栓塞进行治疗。对68例患者采用胃镜检查,采取急救措施并利用药物对患者进行综合治疗(对照组)。结果:观察患者总有效率率为95.59%,对照组患者总有效率为79.41%。比较两组总有效率,发现观察组总有效率显著优于对照组,差异具有统计学意义(P<0.05)。结论:采用数字减影血管造影检查及介入治疗不明原因消化道出血有重要诊断治疗意义,值得在临床上推广应用。
Objective: To explore the method and clinical effect of digital subtraction angiography (DSA) and interventional therapy of gastrointestinal bleeding in unknown reasons. Methods: Sixty-eight patients with gastrointestinal bleeding of unknown cause underwent DSA examination (observation group). The contrast agent spillover, pathological vessels and tumor staining were performed to determine the cause and site of bleeding. The superselective arterial catheter was used to perfuse the posterior pituitary Stop bleeding or gelatin sponge embolization for treatment. Sixty-eight patients underwent gastroscopy, first-aid measures and the use of drugs to treat patients (control group). Results: The observed total effective rate was 95.59%, the control group, the total effective rate was 79.41%. The total effective rate was compared between the two groups. The total effective rate in the observation group was significantly better than that in the control group, with significant difference (P <0.05). Conclusion: The digital subtraction angiography and interventional treatment of unknown causes of gastrointestinal bleeding have important diagnostic and therapeutic significance, it is worth in the clinical application.
