ABSTRACT

BACKGROUND AND AIMS: The aim of this study was to identify clinical and imaging predictors of arterial extravasation, post embolization rebleeding and 30-day mortality in gastrointestinal (GI) bleeding. METHOD: This retrospective study included 114 patients who underwent angiography for upper or lower GI bleeding. Multivariate logistic regression was used to identify clinical and imaging predictors. RESULTS: Angiography demonstrated arterial extravasation in 22 patients (19%) and embolization was performed in 48 (42%) patients including prophylactic embolization in 26 (56%). Fall in hemoglobin level from baseline was an independent predictor of arterial extravasation with 65% increased odds for every unit drop (OR 1.65, 95%CI 1.13-2.40, p=0.01). Age <60 years was a negative predictor of rebleed within 30-days (OR 0.94, 95%CI 0.89-1.00, p=0.04). Patients with a history of malignancy were more likely to rebleed (OR 4.4, 95%CI 1.06-18.36, p=0.04). Hemodynamic instability prior to angiography (OR 13.22, 95%CI 1.65-106.07, p=0.02), history of malignancy (OR 1.36, 95%CI 1.49-10.49, p=0.01), number of units of platelets transfused (OR 1.42, 95%CI 1.02-1.97, p=0.04) and rebleed after angiography (OR 46.8, 95%CI 4.80-456.14, p<0.01) were predictors of 30-day mortality. Prophylactic embolization was not a predictor of rebleed or 30-day mortality. CONCLUSIONS: This paper identified important clinical predictors of arterial extravasation, rebleed and 30-day mortality in GI bleedings, which will assist in patient selection and help to improve the overall angiographic management of GI bleeding.

ABSTRACT

A 66-year old woman had a left breast mass. Biopsy showed invasive ductal carcinoma. A PET/CT scan demonstrated hypermetabolism in the left breast and atypical heterogeneously increased uptake throughout the skeleton as well as a minimally FDG-avid right adrenal myelolipoma. PET/CT 4 months later after 6 cycles of neoadjuvant chemotherapy demonstrated increased size and FDG avidity of this adrenal mass concerning for metastasis and uniformly increased skeletal FDG avidity. Biopsy demonstrated adrenal myelolipoma. The growth and increased FDG avidity of the adrenal myelolipoma were due to the action of colony-stimulating factors on the tumor's hematopoietic component.
