摘要
目的 探讨选择性动脉造影和造影时机选择在不明原因下消化道出血诊断中的价值。方法 运用Seldinger技术对 32例患者进行选择性肠系膜上、下动脉及其分支造影 ,其中少量出血患者 17例 ,中至大量 15例。首次出血 3例 ,2次以上反复出血 2 9例。结果 32例中 2 8例发现病变 (87.5 % ) ,其中肿瘤性病变 (n=15 )非肿瘤性病变 (n=13) ,少量出血未见造影剂外溢征 ;中至大量出血中造影剂外溢征占 33%。结论 选择性动脉造影检查下消化道出血是一种安全、有效的方法 ,在少量出血和出血间歇期仍有很大价值 ;
Objective To invest igate the value and the chance of select ive angiography in the diagnosis of intr actable lower gastrointestinal hemorrhag e.Methods Thirty-two cases were subjected to selective angiography using Seldinger technique.The severity of bleeding and the number of cases were :slight bleeding( n =17),moderate and ma ssive bleeding( n =15).And among these w ere the cases of first episode( n =3) an d recurrence of bleeding( n =29).Res ults Positive signs were demonstrate d in 28(87.5%) cases,including tumorous lesion( n =15)and non-tumorous lesion( n =13).Contrast medium leakage sign was d emonstrated in 5(33.3%)of the 15 moderat e and massive bleeding cases;no leakage sign was found in slight bleeding cases.Conclusion Selective angio graphy is an effective and safe method f or examining the cases of no cause lower digestive tract hemorrhage.It is still of great value to the examination of the slight bleeding cases and the cases in the intermittent phase;the aim of angiog raphy is to locate the site of lesion,wh ich is more important than the demonstra tion of leakage sign.
