Fatal cerebral thrombosis after pericardiectomy.

Abstract

Background: Pericardiectomy due to constrictive pericarditis is usually safe procedure. There was a rare event of thrombosis after pericardiectomy, which was mainly accounted by low-cardiac-output syndrome.

Case presentation: Here, we report the case undergoing pericardiectomy after constrictive pericarditis, with fatal cerebral thrombosis after pericardiectomy confirmed by endovascular mechanical thrombectomy. Even though recanalization was completed and suggestive decompressive craniectomy was in preparation, the patient still died for cerebral hernia due to severe edema. The causes of cerebral thrombosis after pericardiectomy in this case was accounted by the persistence of nonpliable pericardium encasing the left ventricular wall limited local myocardium motor, pro-coagulable state due to thermal transmission during decortication like radiofrequency ablation under the condition of postoperative atrial fibrillation and rapid ventricular rates precipitated the information of mural thrombus in cardiac cavity and migration into the main branch of the aortic arch.

Conclusion: The protocol of prompt aggressive anticoagulation prophylaxis would be vigilantly recommended for the patients undergoing pericardiectomy.
