Outcome and predictive factors of successful transarterial embolization for the treatment of acute gastrointestinal hemorrhage

BackgroundTransarterial embolization (TAE) is an effective procedure for the treatment of acute gastrointestinal bleeding (GIB). Factors associated with clinical success have not been well delineated.PurposeTo evaluate the technical and clinical successes of TAE for acute GIB in order to identify factors influencing clinical success and in-hospital mortality.Material and MethodsThis was a retrospective study of 70 consecutive patients with GIB who underwent angiography and embolization between January 2004 and December 2011. The technical success rate, clinical success rate, and in-hospital mortality were calculated by percentage. Clinical parameters, angiographic, and embolization data were assessed for factors influencing clinical success and in-hospital survival using univariate and multivariate analysis. Statistical significance was set at P value <0.05.ResultsThe technical success rate was 98.6%. The primary clinical success rate was 71.4% and the secondary clinical success rate after repeat emboliza...
