Following resection of the left colon, a 67-year-old obese woman develops left-sided leg edema due to deep-vein thrombosis. She is placed on anticoagulants, but after 2 weeks of warfarin (Coumadin), she develops a pulmonary embolus with slight hypoxemia. What should the next step in management involve?
In general, failure (or inability) to continue anticoagulants is an indication to insert an IVC filter to minimize the possibility of serious and possibly fatal pulmonary embolus.
Increasing the dose of anticoagulants
Discontinuing anticoagulants
Use of an inferior vena cava (IVC) filter
CT scan of the leg and abdomen
Small & Large Intestine
