Pathophysiologic evaluation of chronic XXXX with ambulatory venous pressure studies.

@entity1 @entity3885 @entity337 @entity2979 @entity4096
Seven normal controls and 51 lower extremities with @entity4096 in 45 @entity1 were studied with ambulatory venous pressure. Measurements were done at rest and during 15 seconds of exercise without a tourniquet and with 1 or 2 tourniquets at different levels of the extremity. The decrease in pressure during exercise and the time to return to standing levels were used to calculate a venous sufficiency index. Six pathologic categories were identified in @entity1 with chronic @entity2979 . Incompetence of perforators was present in 17 cases. A combination of long saphenous vein and perforator @entity337 was detected in 10 cases. Thirteen cases had a pattern of regurgitant deep vein @entity337 . Two cases had @entity337 of the saphenous system. A deep @entity3885 pattern was present in 3 other @entity1 . Ascending and retrograde phlebography was done in 30 of these cases. There was an 83.3% correlation between the venous pressure and phlebographic tests. Contrast studies were found to be complementary and added extra-anatomical information. Based on these special studies, a rational approach to the treatment of @entity4096 has evolved. The early results are encouraging.
