Abstract
Since July, 1985, the authors have studied 23 patients with history and physical findings of venous insufficiency syndrome (VIS) confirmed by venous pressure, muscle biopsy, ascending and descending venography, electromyography, and nerve conduction velocity studies. Clinically, swelling appears to be the most important symptom, along with high venous pressure, particularly ambulatory venous pressure, correlated with venography findings. Muscle atrophy was present in 18 cases. Electromyography and nerve conduction velocity studies yielded abnormal findings in 20 of 23 cases. The authors suggest that nerve conduction velocity and EMG studies could perhaps be used as noninvasive tests for diagnosis and follow-up of cases with VIS.
