Right atrial thrombus formation is a known complication of dialysis catheter placements. We describe the case of a 61-year-old woman with end-stage renal failure who presented with gram-negative septicaemia. A gas-containing filling defect was noted incidentally in the right atrium during a CT scan of the abdomen and pelvis, indicative of a thrombus infected by a gas-forming organism. The finding correlated with a positive blood culture of Klebsiella pneumoniae and the two-dimensional echocardiography finding of an echogenic atrial thrombus.
右心房血栓形成是透析导管放置的已知并发症。我们描述了一例 61 岁女性终末期肾衰竭患者,表现为革兰氏阴性菌败血症。在腹部和骨盆 CT 扫描中偶然发现右心房内有含气充盈缺损,提示血栓被产气微生物感染。该发现与肺炎克雷伯菌的阳性血培养和二维超声心动图发现的回声性心房血栓相关。
