“…To date, multiple studies have looked at vascular complications from osteochondromas, including intermittent compression, pseudoaneurysm, thrombosis, distal emboli, and venous thrombosis or compression. 1 , 2 , 3 , 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 Enlargement of the osteochondroma can lead to compression of the vascular structures, leading to arterial or venous thrombus with subsequent distal embolization. Eschelman et al 7 found that 68% of vascular injuries were pseudoaneurysms secondary to what has been proposed as the osteochondroma's cartilaginous cap ossifying and then the pulsatile nature of the artery rubbing against it, causing damage.…”
