AbstractChronic relapsing exertional compartment syndrome is not only found in young athletic subjects. Non-athletic patients can also suffer from exercise dependent pain in the lower limb. The syndrome is defined by increased tissue pressure in between a closed osteo-fibrous space resulting in disturbed microcirculation and finally irreversible neuroischemic damage. Pain increases during running and disappears gradually at rest. The diagnosis is based on the typical symptoms and so far on the pre-, 1 and 5 min post exercise intramuscular pressure measurement. We first describe sonographic criteria induced by increased compartment pressure, especially for the most frequent anterior compartment syndrome with compression of the deep veins, increased movement of arterial wall and finally enddiastolic closure of the anterior tibial artery. Duplex ultrasound also provides pathogenetic factors like popliteal and anterior entrapment, stenosis or hypoplasia of the anterior tibial artery or thrombosis of the deep muscle veins. Many patients are reporting a pain history over years, resulting in complete reduction of their sporting activity. The knowledge about pathogenesis, symptoms, diagnosis and therapy should help shorten the negative impact of the syndrome on their quality of life.
