AbstractAnticoagulation still remains the primary therapy for venous thromboembolism (VTE) in order to prevent the most life-threatening form of VTE, pulmonary embolism (PE). Nevertheless in some patients anticoagulation is impossible. Then vena caval filters serve as a valuable second line therapy against the most feared complication of VTE, fatal PE. We want to present a patient with preceding PE and DVT in whom for the perioperative period a temporary vena caval filter was placed and who showed the complication of a nearly fatal PE. A seventy-two year-old white male was admitted for thrombolytic therapy for massive pulmonary embolism, which was performed successfully. Some hours later the patient developed gastrointestinal bleeding. An adenocarcinoma of the colon was diagnosed and an end-to-end hemicolectomy performed. A temporal caval filter (Gunther filter) was placed in the infrarenal vena cava for the perioperative period. Seven days later the patient syncopated with acute massive onset of dyspnea. A helix computertomography scan of the lung showed again massive central pulmonary embolism with right heart enlargement. An immediate pulmonary embolectomy had to be performed. Subsequent venal cavography revealed a thrombosed vena caval filter and a thrombus proximal to the filter. This case report should emphasize the fact that although a vena cava filter might be of high benefit in patients with contraindication for anticoagulation to prevent recurrent PE, in some cases it can be insufficient and lead to enormous complications.
