Case 16: Acute Versus Chronic Thromboembolic Disease—Beware!

The distinction between acute and chronic thromboembolic disease is frequently difficult at the time of initial presentation.

Not only are there historical clues, but an understanding of the disparate radiographic appearance between acute and chronic thrombi can often prevent an inappropriate intervention. This case presentation highlights these important considerations.
