Inferior Vena Cava Filter Use in the Setting of Gastrointestinal Blood Loss, Malignancy, and Multiple Thromboembolisms: A Case Report.

Cancer-associated thromboembolism (CAT) is a common yet serious condition that occurs due to the physiological changes brought about by malignancy. The two conditions that are the most prevalent are deep vein thrombosis (DVT) and pulmonary embolism (PE). Anticoagulation is the standard of care for these thrombotic problems, however, in the event these medications are contraindicated, other treatment modalities may be needed. One common example is in the setting of an active bleed, such as gastrointestinal (GI) cancer. A treatment that has been used more frequently in recent years is the inferior vena cava (IVC) filter. These can be placed to provide a physical barrier to prevent a thrombus from moving through the circulation and potentially embolizing critical organs. An advantage of these devices is that they can be placed and removed when the use of pharmacological agents is better indicated. This report is a good example of a situation where an active GI malignancy created a hypercoagulable state leading to multiple thromboembolisms. An IVC filter was placed in the perioperative setting to prevent further thrombus migration while the primary malignancy was cured with a hemicolectomy.
