数字减影血管造影在消化道出血诊断和治疗中的应用

The value of digital subacflon angiography in diagnosis and treatment of gastrointestionai hemorrhage

目的评价数字减影在血管造影诊断与介入治疗在消化道出血中的应用价值。方法36例消化道出血患者进行了DSA检查，对DSA造影阳性的26例患者根据出血的原因和部位，应用不同栓塞剂或垂体后叶素灌注进行介入治疗。结果36例中血管源性出血26例，16例患者造影剂外渗者行栓塞和垂体后叶素灌注治疗后12例患者止血成功，手术后胆囊或胆道出血、胰腺癌术后小肠出血、胃、十二指肠出血患者采用明胶海绵、PVA和（或）弹簧栓子栓塞出血均停止，止血成功率为84．6％（22／26）。结论DSA在消化道出血中具有较高应用价值，可指导动脉栓塞或缩血管药灌注治疗消化道出血性病变。

Objective To evaluate the application value of DSA diagnosis and interventional therapy in gastrointesfinal hemorrhage. Methods 36 eases of gastrointestinal hemorrhage used DSA examination,according to the reason and position,26 cases of the patients that were positive of DSA opacification utilized interventional therapy with different embolic agents or vasopressin perfusion. Results 26 cases of patients in 36 had gastrointestinal hemorrhage, 12 eases of patients in 16 that have extravasation of contrast media were hemostasis by treating with embolizafion therapy and vasopreasin perfusion ,hemorrhage of eholecyst and biliary tract after operation,the patients of small intestinal hemorrhage ,gastroduodenal hemorrhage after the operation of pancreatic carcinoma were embolized with gelfoam,PVA and/or colis were done. The stopped bleeding immediately oecured in 84. 6% （22/26）. Conclusion DSA are more valuable methods for the diagnosis of gastrointestinal hemorrhage. Arterial embolization and/or perfusion of vasoconlrietor substance for treatment of hemorrhage of digestive tract is safe,effec is reliable.
