Delayed pericardial tamponade following central venous recanalization

A patient with central venous occlusion at the junction of the superior vena cava and right atrium underwent endovascular revascularization. The leakage of contrast agents was detected during sharp recanalization that was then managed with covered stent deployment. The initial symptom of facial swelling disappeared and the vital signs were stable after treatment. Regrettably, the patient suffered from the clinical features of cardiac tamponade on the third day post-treatment, which was confirmed by computed tomography. Finally, a pericardial effusion was drained, leading to dramatic improvement in the cardiovascular status of the patient.
