Delayed diagnosis of popliteal artery injury after traumatic knee dislocation: a case report

The popliteal artery damage is present to range from 1.6% 64% of patients with knee dislocation, and it crucial evaluate vascular even if there are no prominent ischemic changes in the distal area. injury by high-energy forces around caused a fall or traffic accident potentially limb-threatening complication traumatic dislocation. blunt trauma has high risk limb amputation because initial symptoms can show normal circulation without urgent ischemia obvious signs. Since collateral branches delay decisive pulseless extremity, major cause amputation. In study, we describe rare case delayed diagnosis after requiring revascularization surgery. After occluded artery, graft interposition was performed, successful restoration confirmed. This illustrates that, ankle-brachial index >0.9 equal pedal pulse uninjured serial evaluation required soft signs such as diminished pulses, neurologic signs, multiple ligament ruptures since be clinicians need regard rupture hard sign, immediate computed tomography angiography helpful for accurate treatment.
