A 49-year-old military male presented with melena since five days; furthermore other symptoms of anemia, including fatigue, dizziness and palpitations on exertion were noted. There was no history of previous gastro-intestinal bleeding and there was only sporadic use of alcohol. Clinical assessment revealed a stable patient with low blood pressure (107/67 mmHg) and normal pulse frequency (67 pulses/min). Laboratory analysis showed macrocytic anemia (haemoglobin 6.2 g/dl); other laboratory findings were normal, including coagulation, ionogram, liver and renal function. Upper endoscopy revealed a large blood clot in the fundus without active bleeding and a gastric fundal varix with an erosion was suspected. The patient was treated initially with administration of two units of packed cells, terlipressin (6 mg/24 hours) and a proton pump inhibitor. Contrast-enhanced triple-phase computed tomography (CT) was performed, showing a normal aspect of the liver without signs of portal hypertension and a cluster of enlarged arteries in the gastric wall (Fig. 1a) without clear contrastextravasation. In addition, several metallic coils were found in and around the splenic hilum. No ectopic splenic tissue could be visualized in or around the stomach. At that time, the patient remembered to be treated by catheter-directed embolization for splenic trauma 30 years ago. It was hypothesized that gastro-splenic collaterals developed over the years related to main splenic artery coil-embolization. Subsequently, the patient was referred to interventional radiology for further and definitive management. Under local anesthesia, through a 4 French sheath, a Simmons 1 catheter (Glidecatheter, Terumo Europe, Leuven, Belgium) was navigated into the celiac trunk. Contrast injection revealed enlarged gastrosplenic arterial collaterals between the main splenic artery and the upper pole splenic endbranches, bypassing the coil-occluded distal segment of the main splenic artery (Fig. 1b). These gastrosplenic collaterals were superselectively cannulated with use of a microcatheter (Progreat 2.4, Terumo Europe, Leuven, Belgium) and embolized with a 1/3 mixture of enbycrylate (Glubran, GEM srl, Viareggio, Italy) and Lipiodol (Guerbet, Villepinte, France). Completion angiography showed complete occlusion of the gastrosplenic collaterals and some droplets of glue migrating into the splenic upper pole (Fig. 2a). Computed tomography 2 days later, revealed a cast of glue in the hypertrophied collaterals in the gastric wall and some droplets of glue in the splenic parenchyma (Fig. 2b). The postinterventional course was uneventful without clinical evidence for gastric or splenic ischemia; no episode of bleeding recurrence was noted. A follow-up upper endoscopy six weeks after the embolization showed a persistent tangle of thick folds and a strand coming out of the erosion: most probably a part of the embolization cast (Fig. 3).
