The use of Minnesota and modified Sengstaken-Blakemore tubes for balloon tamponade in acute variceal haemorrhage has declined with the availability of modern endoscopic techniques. However, in massive uncontrolled haemorrhage their use may still be required. They are very effective in controlling acute bleeding, but are associated with a range of potentially serious complications. This case demonstrates an unusual complication of the use of a Minnesota tube in a gentleman with a large gastric variceal bleed. The patient developed inferolateral ST-segment elevation on a 12-lead ECG which resolved rapidly following aspiration of 2000 mL of blood from the gastric port of the Minnesota tube. It was thought that the distension of the stomach, along with the traction applied to the Minnesota tube, resulted in external compression of the diaphragmatic surface of the heart and the observed ECG changes.
随着现代内镜技术的出现,明尼苏达管和改良的森斯塔肯-布莱克莫尔管在急性静脉曲张出血中用于球囊压迫的情况已有所减少。然而,在大量难以控制的出血中,可能仍需要使用它们。它们在控制急性出血方面非常有效,但会伴有一系列潜在的严重并发症。本病例展示了一名患有巨大胃静脉曲张出血的男性使用明尼苏达管时出现的一种不寻常并发症。患者在12导联心电图上出现下外侧ST段抬高,在从明尼苏达管的胃端口抽出2000毫升血液后迅速缓解。据认为,胃的扩张以及明尼苏达管施加的牵引力导致心脏膈面受到外部压迫,从而出现了观察到的心电图变化。
