Tourniquet failure (TF) occurs when blood enters a limb beneath the tourniquet. This review analyzes
the causes of primary TF – when the blood flow is not occluded a-priori, and secondary TF – when
arterial flow is initially stopped, but resumes some time into the case. If TF occurs, the tourniquet must be removed to prevent venous engorgement, stagnation and clotting.
