title: Hemopericardium after superior vena cava stenting for malignant SVC obstruction: the importance of contrast-enhanced CT in the assessment of postprocedural collapse.
abstract: We report the complication of hemopericardium following superior vena cava (SVC) stenting with an uncovered Wallstent in a patient with malignant SVC obstruction. The patient collapsed acutely 15 min following stent placement with hypoxemia and hypotension. A CT scan demonstrated a hemopericardium which was successfully treated with a pericardial drain. The possible complications of SVC stenting, including hemopericardium, pulmonary embolism, mediastinal hematoma, and pulmonary edema from increased venous return resulting from improved hemodynamics, ensure a wide differential diagnosis in the postprocedural collapsed patient and this case emphasizes the important role of contrast-enhanced CT in the peri-resuscitation assessment of these patients.
