Abstract:
Objective To evaluate the effect of digital subtraction angiography and transcatheter embolization for gastrointestinal hemorrhage.Methods Twenty patients with gastrointestinal hemorrhage received celiac arteries,superior mesenteric arteries and inferior mesenteric arteries angiography. Superselective angiography were performed when the arteries were suspicious by clinic or angiogrraphy.Ten patients with definite diagnosis and manifestation of hemorrhagic arteries by angiography were embolized after superseleetive catheterization with gelfoam particles,gelfoam particles and coils,polyvinyl alcohol particles. Results The positive signs were observed in 13 cases.The DSA features including contrast medium accumulation in the gastrointestinal tract outside vascular,aneurysm,tumorous vascularization and staining, artery affect and local vasospasm.The bleedings were stopped immediately in 8 patients.No rebleeding and intestinal ischaemia or necrosis were observed in 30 days.One patient died in the second day after embolization from multiple organ failure.Rebleeding occurred 3 days after embolization in another patient, and was recovered after surgical operation.Conclusion DSA is more effective for the diagnosis of gastrointestinal vascular malformation and tumors complicating acute bleeding.Transcatheter embolization is effective and safe to control the hemorrhage.
