Popis: Computed tomographic mesenteric angiography (CTMA) is increasingly adopted in patients with massive lower gastrointestinal (LGI) bleeding. However, a positive computed tomography scan does not always translate to a positive invasive mesenteric angiography (MA) when performed. The aim of this study was to identify factors that could predict a positive invasive MA following a positive CTMA. A review of all patients with LGI haemorrhage who had a positive CTMA followed by an invasive MA was performed. From July 2009 to October 2012, 33 positive CTMA scans from 30 patients were identified. Of the 33 bleeding points, 28 were in the colon, while 5 were in the small intestine. Diverticular disease accounted for 20 of the bleeding points. The median duration from the CTMA to the invasive MA was 165 (74–614) min. Of the 33 invasive MAs that were performed, only 14 demonstrated positive extravasation. Factors that were significant for a positive invasive MA included non-diverticular aetiology (odds ratio (OR), 6.75, 95 % confidence interval (CI), 1.43–31.90, p = 0.029) and haemoglobin
