A new sequential pneumatic device for the prevention of deep vein thrombosis.

A new sequential pneumatic instrument for the prevention of deep vein thrombosis (DVT), the Lympha Press, was investigated in neurosurgical patients. In the control group, 50% of patients developed DVT and in the treated group only 4.3% were affected. These results demonstrate the highly beneficial effect of this method of preventing DVT during and after surgery, especially when the use of other preventive methods is precluded.
