The most common reason for arteriovenous (AV) graft failure is venous obstruction caused by intimal hyperplasia. Early failures are usually due to technical issues, while late failures are usually caused by intimal hyperplasia developing on the venous side of the graft. Lower extremity fasciotomies involve making two incisions. The first incision is made posteriorly along the medial tibia to open the superficial posterior space. The soleus muscle is then longitudinally incised to open the deep posterior space. A second incision is made anteriorly along the lateral fibula to access the anterior and lateral muscle compartments. Injury to the superficial peroneal nerve during this procedure would result in decreased ability
