COMPLICATIONS of surgical procedures involving the abdominal aorta and iliac arteries are relatively common, although, as experience has increased, the incidence of these sequelae has progressively decreased. A wide variety of complications, some common to any abdominal operation and others specific to operations on the great vessels, has been reported. Yet, thrombosis of the accompanying veins is an uncommon complication. This is particularly puzzling in view of the intimate relation of veins to arteries and the possibility of inadvertent trauma. In fact, we have been unable to find any reports of thrombosis of the inferior vena cava or iliac veins after aorto-iliac operations. For this reason, 2 cases are reported of phlegmasia cerulea dolens, occurring 2 and 3 weeks, respectively, after aorto-iliac operations in which there was no known trauma to the iliac veins. Both cases were successfully treated by different methods.
