A case of greatly increased blood flow in the region of a fracture with malunion of the left femur, both in the flow and immediate blood pool studies during three phase bone imaging, is presented. The sluggish left femoral artery flow resulted from the greatly increased regional perfusion and is similar to the findings in acute osteomyelitis. The sluggish left femoral artery flow and greatly increased regional perfusion of the site is probably best explained as a regional "neurovascular flush" resulting from the pain caused by the malunion of the fracture and/or hyperemia in the area of the malunion responding to inflammation.
本文报告一例左股骨骨折畸形愈合部位在三相骨显像的血流和即时血池研究中血流均显著增加的病例。左股动脉血流缓慢是由于局部灌注显著增加所致，与急性骨髓炎的表现相似。左股动脉血流缓慢以及该部位局部灌注显著增加，很可能最好解释为骨折畸形愈合引起的疼痛和/或畸形愈合部位对炎症反应的充血所导致的局部“神经血管充血”。
