Cardiac herniation presenting as superior vena cava obstruction syndrome after intrapericardial pnemonectomy for locally advanced lung cancer---case report.

Introduction: Cardiac herniation is a rare complication after pulmonary surgery, and there are only a few reports about it. We now report a case of cardiac herniation presenting as superior vena cava obstruction after pneumonectomy.

Case Presentation: A-52-years old woman diagnosed right pulmonary squamous cell carcinoma was carried out right pneumonectomy, the pulmonary artery and right superior pulmonary vein were dissected and ligated intrapericardial. The patient developed tachycardia arrhythmias, hypotension, followed by loss of consciousness at about 18 h after operation. After resuscitation, the patient was conscious but developed cyanosis of the superior vena cava drainage area, uropenia, and hypotension (80/30 mmHg). Bedside-echocardiography showed that the SVC was obstructed due to thrombus formation. Chest radiography a shift of the heart into right hemithorax. Rethoracotomy was performed and the herniated heart was replaced into the pericardium, and the pericardium was repaired with Gore Tex patch. The patient recovered smoothly after the second surgery.

Conclusion: Cardiac herniation is a rare and fatally complication after thoracic surgery, and the prompt recognition with timely intervention is life-saving. Cardiac herniation is a rare but fatal complication of pneumonectomy. The increasing frequency of surgical resection for locally advanced thoracic carcinoma has led to a renewed emphasis regarding early diagnosis and treatment for cardiac herniation. Here we discuss a case of cardiac herniation presented with acute superior vena cava obstruction syndrome and hemodynamic instability after intrapericradial right pneumonectomy.
