PCD is fully reversible if the causal venous thrombus is promptly removed. In the 40-60% of people who go on to develop venous gangrene, there is a 20-50% risk of amputation and 20-40% mortality rate. Following PCD resolution patients are more likely to develop venous insufficiency and post-thrombotic syndrome There is a grading system that has been established: * Grade I = non-complicated (no blistering, strong sensory-motor function and strong distal pulses) * Grade II = impending venous gangrene (blistering, weak sensory-motor function and weak distal pulses) * Grade III = venous gangrene
