The concurrent presentation of symptomatic malignant pericardial hemorrhage and venous thromboembolism is a rare event that poses a clinical dilemma. Existing VTE guidelines do not indicate when, or if, anticoagulation therapy should be started after the treatment of the pericardial bleed. We performed a systematic review to compile the published clinical evidence on the occurrence of coexisting pericardial hemorrhage and VTE in cancer patients and to describe the clinical presentations and bleeding and thrombosis outcomes before and after anticoagulation therapy. We studied published case reports on patients with cancer who presented to the hospital with pericardial hemorrhage and VTE through April 11, 2019. We found seven published case reports. All patients had suffered from a pulmonary embolism and had pericardiocentesis during hospitalization. Five patients (71%) had lung cancer. Four patients (57%) were started on anticoagulation after pericardial drainage and survived the index event. Two patients (29%) were not started on anticoagulation after pericardiocentesis; only one of these patients survived the hospitalization. Pericardial bleeding risk in cancer may be inherent to malignancy, and it is unclear if anticoagulation use increases the risk of recurrent pericardial bleeding. The management of pericardial bleeding typically requires pericardiocentesis, and clinical registries, prospective collaboration projects, and case adjudication are needed to establish the safety of initiation of antithrombotic therapy in such patients.
