- W2112578252 abstract "Purpose To report outcome of transcatheter arterial embolization (TAE) of colorectal arterial bleeding Materials and Methods From January 2006 to August 2012, 68 patients with hematochezia were diagnosed to have colorectal arterial bleeding angiographically. The location and arterial feeders of the hemorrhagic lesion were determined based on CT and conventional angiographic findings. Presence of bleeding tendency, multiplicity of hemorrhagic feeders, and usage of embolic material were analyzed. Clinical outcome including technical success rate and rebleeding rate was determined and compared between colonic hemorrhage group and rectal hemorrhage group. Procedure-related complication was also evaluated. Results Location of hemorrhage was colon (n=31) and rectum (n=37), respectively. Patients with rectal bleeding were more likely to have bleeding tendency and multiple hemorrhagic feeders than those with colonic bleeding (P=.009 and .046, respectively). N-butyl cyanoacrylate (n=49), gelatin sponge particle (n=15), coil (n=1), and blood clot (n=1) were used while 2 patients could not be treated. Technical success rate were 94.1% for entire group, 96.8% for colonic group and 91.9% for rectal group (P=.394). Rebleeding rate was higher in rectal hemorrhage group than in colonic hemorrhage group (35.1% vs 3.2%, P=.001). Procedure-related complication rate was 5.9% (n=4). Conclusion TAE is a safe and effective treatment method for colorectal arterial bleeding with high technical success rate of 94%. However, there is considerable risk of rebleeding in patients with rectal bleeding." @default.
