The Interventional Embolization for Hemorrhage Caused by Pelvic Malignant Tumor

Objectives: To study the value of super-selected arterial embolization in treatment of pelvic malignant tumor hemorrhage. Methods: A total of 11 patients with hematuria, hematochezia or colporrhagia caused by pelvic malignant tumor admitted to our hospital were selected, all the patients carried on angiography of aorta abdominals, inferior mesenteric artery and bilateral internal iliac artery, and carried on selective artery embolization of responsible artery. Hemostasis, the occurrence of adverse reaction and complication were observed after embolization. Results: Angiography in all patients were successful, Super-selected angiography in 1 patient of inferior mesenteric artery failed because of stenosis, the other 1 patient of lumbar artery failed because of tortuous, the remaining patients underwent super-selective angiography and embolizafion of the responsible artery. Hemorrhage was significantly reduced in 6 patients, 5 patients stopped hemorrhage. 5 patients suffered fever after embolization; no severe complications were observed.1 patient died of re-bleeding after 6 months. Conclusion: Super-selective arterial embolization is effective and relatively safe in the treatment of hemorrhage caused by pelvic malignant tumor; at least in 2 weeks, it can avoid mortality caused by hemorrhage; The responsible artery vessels were mainly originated fi'om inferior mesenteric artery and unilateral or bilateral internal iliac artery; The curative effect can be judged according to whether the bleeding is reduced or not; Big diameter Gelatin Sponge Particle Embolic Agent was recommended in order to avoid severe complications after embolization.
