Abstract:

Objective: To demonstrate the safety and efficacy of endovascular embolization with N-butyl cyanoacrylate glue in acute bleeding. Methods: The data of 31 patients who underwent endovascular embolization using glue due to acute visceral hemorrhage were retrospectively evaluated. In order to detect the bleeding focus before the procedure, computed tomography with contrast-enhanced and non-contrast phases was routinely performed on the suspected bleeding site. Technical success was accepted as the closure of the targeted artery in control angiography, and clinical success was defined as the absence of bleeding that would require reoperation within one month postoperatively. Results: Eleven patients with gastrointestinal tract or vaginal bleeding or hematuria due to malignancy, nine with hemoptysis due to infection sequelae or bronchiectasis, four with bleeding secondary to percutaneous medical procedures, three with trauma-related hemorrhage, and four with hemorrhage due to peptic ulcers were treated with endovascular embolization. Embolization was undertaken using a glue-lipiodol mixture of 5% in 17 patients and 10% in 14 patients. Conclusion: N-butyl cyanoacrylate is a safe embolizing material with high technical and clinical success in patients with active bleeding.
