A wide range of vascular anomalies occurs in the gastrointestinal tract, the most specific being those of hereditary haemorrhagic telangiectasia. However, single gastric angiodysplasias are being recognised with increased frequency as an important cause of upper gastrointestinal bleeding. We present a case of gastric arteriovenous malformation, and review the general features that differentiate single gastric angiodysplasia from other vascular anomalies and syndromes associated with gastric vascular disease. Further reports are needed to confirm that gastric angiodysplasias constitue a unique and separate entity. If so, successful management should be obtained by resection of the whole angiodysplastic area.

Background Cardiogenic shock (CS) is associated with high mortality. The purpose of this study was to assess the impact of Hospital structure-related variables on mortality in patients with CS treated at percutaneous and surgical revascularization capable centers (psRCC) from a large nationwide registry. Methods Retrospective observational study including consecutive patients with main or secondary diagnosis of CS and ST elevation myocardial infarction (STEMI). Patients discharged from Spanish National Healthcare System psRCC were included (2016-2020). The association between the volume of CS cases attended by each center, availability of Intensive Cardiac Care Unit (ICCU) and heart transplantation (HT) programs and in-hospital mortality was assessed by multilevel logistic regression models. Results The study population consisted of 3,074 CS-STEMI episodes, of whom 1,759 (57.2%) occurred in 26 centers with ICCU. A total of 17/44 hospitals (38.6%) were high-volume centers and 19/44 (43%) centers had HT programs availability. Treatment at HT centers was not associated with a lower mortality (p = 0.121). Both high volume of cases and ICCU showed a trend to an association with lower mortality in the adjusted model (OR: 0.87 and 0.88, respectively). The interaction between both variables was significantly protective (OR 0.72; p = 0.024). After propensity score matching, mortality was lower in high volume hospitals with ICCU [OR = 0.79; p = 0.007]. Conclusions Most CS-STEMI patients were attended at psRCC with high volume of cases and ICCU available. The combination of high-volume and ICCU availability showed the lowest mortality. These data should be taken into account when designing regional networks for CS management.
