Application of DSA diagnosis and interventional embolization therapy in various acute arterial bleeding

Objective To evaluate the clinical effect of digital subtraction angiography (DSA) diagnosis and interventional embolization therapy in various acute arterial bleeding. Methods Twenty two patients with various acute bleeding, including hepatic bleeding (n=4), postpartum bleeding (n=7), induced abortion bleeding (n=2), large hemptysis (n=6), gastrointestinal bleeding (n=3), underwent selective DSA and transcatheter arterial embolization with gelfoam particles and/or polyvinyl alcohol (PVA) particles. Results The positive signs of bleeding were observed in 22 cases drring DSA. Bleeding stopped immediately in all patients after embolization. During the follow-up of 3-24 months , large hemptysis recurred in 1 patients 4 months after embolization, and was treated successfully with re-embolization. No serious complications occured in all patients. Conclusion DSA is valuable for the diagnosis of various acute arterial bleeding. Interventional embolization therapy is a quick, safe and effective method to control hemorrhage, and should be taken as the first choice.
