探讨急症动脉性消化道大出血的介入治疗价值。

回顾性分析因消化道大出血急症行动脉造影的75例患者资料，将休克指数<1的病例规定为A组，休克指数≥1的病例规定为B组，对比分析A、B两组的阳性检出率。将使用螺圈栓塞的病例规定为C组，明胶海绵联合螺圈栓塞的病例规定为D组，对比分析C、D两组的复发率。分析影响阳性检出率、出血复发以及严重并发症发生的因素。

该75例患者的首次阳性检出率为56%（42/75），A、B两组病例的阳性检出率有统计学意义（P<0.05），其余33例首次检查结果为阴性的患者有3例再次接受造影检查发现出血点，全部45例造影阳性的患者均接受介入栓塞治疗，技术成功率为100%。C、D两组的出血复发率无统计学意义（P>0.05），D组有2例患者发生肠道缺血坏死。

介入栓塞是目前治疗胃肠道动脉性出血的重要方法，不但能够明确诊断，而且能够通过治疗挽救患者生命，一旦诊断为动脉性消化道大出血，应该尽早行介入治疗。

To investigate interventional therapy value in the acute gastrointestinal arterial hemorrhage.

Date of 75 patients with arteriography for the acute gastrointestinal hemorrhage was retrospectively analyzed, and cases in which the shock index<1 were divided as group A, the shock index ≥1 as group B. Comparative analysis of the positive detection rate were made in the two groups. Cases using coil to embolize prescribed as group C, and cases with gelatin sponge coil embolism prescribed as group D. Comparative analysis of recurrence rate were made in these two groups .Factors affecting the positive detection rate, recurrence of bleeding and severe complications were analyzed in the end.

Positive detection rate of 75 cases was 56% (42/75), and it has statistic significance of positive detection rate in group A and B (P <0.05). All 42 patients with contrast positive took the interventional embolic treatment, for technical success rate was 100%. Recurrence rate of bleeding in group C and D has no statistic significance (P>0.05). Two cases of intestinal ischemia necrosis showed in these two groups. Three patients with negative results of DSA examination were found re-bleeding after radiography, whereas interventional therapy was done at the same time.

Interventional embolization is one of the vital methods in treatment of gastrointestinal arterial hemorrhage, not only can clarify diagnosis, but also save patients life promptly. Interventional therapy therefore should be done as soon as possible when patients diagnosed as gastrointestinal hemorrhage.
