Abstract:
This paper reports a case of hypotension caused by superior vena cava stenosis due to hemodialysis catheter. A 65-year-old female maintenance hemodialysis patient presented with intolerable hypotension during dialysis. The dialysis access was tunnel-cuffed catheter. Computed tomography angiography and digital subtraction angiography revealed occlusion at the junction of the superior vena cava and the right atrium. After the superior vena cava was opened by endovascular treatment, the patient's blood pressure returned to normal and could tolerate 4 hours of regular hemodialysis. Reviewing relevant literature, occlusion of superior vena cava is one of the causes of hypotension in maintenance hemodialysis patients, and endovascular treatment to open the occluded superior vena cava can effectively correct this kind of hypotension.
