ABSTRACT

OBJECTIVE: To evaluate the usefulness of a published clinical decision support tool to predict the likelihood of a retrievable inferior vena cava (IVC) filter being maintained as a permanent device. METHODS: This multicenter retrospective cohort study included 1498 consecutive patients (852 men and 646 women; median age, 60 years; range, 18-98 years) who underwent retrievable IVC filter insertion between January 2012 and December 2019. The indications for IVC filtration, baseline neurologic disease, history of venous thromboembolism (VTE), and underlying malignancy were recorded. Accuracy, sensitivity, and specificity of a published clinical support tool were calculated to determine the usefulness of the tool. RESULTS: The majority of filters (1271/1498 [85%]) were placed for VTE with a contraindication to anticoagulation. A history of VTE was present in 811 of 1498 patients (54%) patients; underlying malignancy in 531 of 1498 patients (35%), and neurological disease in 258 of 1498 patients (17%). Of the 1498 filters, 456 (30%) were retrieved, 276 (18%) were maintained as permanent devices on follow-up, and 766 (51%) filters were not retrieved. The accuracy of the clinical prediction model was 61%, sensitivity was 60%, and specificity was 62%. CONCLUSIONS: A previously published clinical decision support tool to predict permanence of IVC filters had modest usefulness in the examined population; this factor should be taken into account when using this clinical decision support tool outside of the original study population. Future studies are required to refine the predictive capability of IVC filter decision support tools for broader use across different patient populations.

ABSTRACT

PURPOSE: The purpose of this study was to assess safety, efficacy, and clinical outcomes following transcatheter arterial embolization (TAE) of acute gastrointestinal (GI) bleeding. MATERIALS AND METHODS: Ninety-five patients (male:female ratio = 53:42, mean age 62 years) that underwent 95 TAEs for GI hemorrhage between 2002 and 2010 were retrospectively studied. Seventy-six of 95 (80 %) patients had upper GI bleeds and 19/95 (20 %) patients had lower GI bleeds. A mean of 7 (range 0-27) packed red blood cell units were transfused pre-procedure, and 90/95 (95 %) procedures were urgent or emergent. Twenty-seven of 95 (28 %) patients were hemodynamically unstable. Measured outcomes included procedure technical success, adverse events, and 30-day rebleeding and mortality rates. RESULTS: Bleeding etiology included peptic ulcer disease (45/95, 47 %), cancer (14/95, 15 %), diverticulosis (13/95, 14 %), and other (23/95, 24 %). Vessels embolized (n = 109) included gastroduodenal (42/109, 39 %), pancreaticoduodenal (22/109, 20 %), gastric (21/109, 19 %), superior mesenteric (12/109, 11 %), inferior mesenteric (8/109, 7 %), and splenic (4/109, 4 %) artery branches. Technical success with immediate hemostasis was achieved in 93/95 (98 %) cases. Most common embolic agents included coils (66/109, 61 %) and/or gelatin sponge (19/109, 17 %). Targeted versus empiric embolization were performed in 57/95 (60 %) and 38/95 (40 %) cases, respectively. Complications included bowel ischemia (4/95, 4 %) and coil migration in 3/95 (3 %). 30-day rebleeding rate was 23 % (22/95). Overall 30-day mortality rate was 18 % (16/89). Empiric embolization resulted in similar rebleeding (23 vs 24 %) but higher mortality (31 vs 9 %) rates compared to embolization for active extravasation. CONCLUSIONS: TAE controlled GI bleeding with high technical success, safety, and efficacy, and should be considered when endoscopic therapy is not feasible or unsuccessful.
