[Renal replacement therapy in a polytraumatized patient with hemophilia]

Renal failure is a rare complication of hereditary coagulopathies. However, when it occurs, it rapidly progresses to a stage that requires replacement of renal function. Major problems include the choice of dialysis method, prevention of complications and supplementation of deficient factor. In hemodialysis, it is challenging to prevent system clotting and avoid bleeding. We present a case of polytraumatized male patient with hemophilia A, who developed compartment syndrome with acute renal failure. Continuous venovenous hemodialysis (CWHD) improved his condition and he recovered his kidney function. However, over the next few days he developed severe sepsis with deterioration of renal function. CWHDF (hemodiafiltration) was restarted. Several large hematomas were found in the abdominal cavity and in the inguinal region, one of them inducing compartment syndrome with leg necrosis. The patient died from cardiorespiratory arrest.
