Popliteal Artery Thrombosis in a Young Patient Secondary to Proximal Tibial Osteochondroma

Popliteal artery occlusion is mainly seen in elderly patients with late stage atherosclerotic occlusive disease. In young, nonsmoking patients, popliteal artery occlusion can be caused by a variety of other etiologies. The diagnosis is suspected clinically and confirmed with ultrasound, computed tomography angiogram (CTA) or angiography, which can also aid in understanding the underlying cause. We present a 40-year-old very active male, who developed progressive symptoms of claudication over a 4 months interval and was found to have a thrombosed popliteal artery secondary to external compression from a tibial osteochondroma. The patient was treated with in-situ saphenous vein bypass from the above knee popliteal artery to the anterior tibial artery. The bypass was widely patent at 24 months.
