Calf vein compliance increases following bed rest after aortocoronary bypass surgery

Abstract

Early post-operative ambulation (< 3 days) is expected to decrease the risk of venous thrombosis, whereas late ambulation (> 7 days) increases the risk of orthostatic hypotension. The effect of post-operative bed rest on calf vein compliance was studied before (D - 1) and 7 days (D + 7) after aortocoronary bypass surgery in 50 patients (41 men and nine women, 65 +/- SD 10 years). Calf vein compliance was measured by strain gauge plethysmography and stepwise increases in thigh congestive pressure from 20 to 60 mmHg. Calf compliance [median (25 percentile-75 percentile)] increased significantly by 48% from D - 1 to D + 7 [0.044 (0.039-0.051) vs. 0.065 (0.048-0.083) ml (100 ml mmHg)-1, P < 0.001]. This increase was reflected as increased calf volume for the 50 mmHg [D-1 2.10 (1.75-2.65) vs. D + 7 2.60 (1.70-3.00) ml 100 ml-1, P < 0.01] and 60 mmHg [D - 1 2.50 (2.10-2.95) vs. D + 7 3.20 (2.30-4.00) ml 100 ml-1, P < 0.001] occlusion pressure levels. The associated pathologies (diabetes and arterial hypertension) and NYHA grades had no significant influence on the increase in compliance. Among the vasoactive therapeutic regimens, calcium channel blockers contributed significantly to the increased calf compliance, but only on D-1. The...Continue Reading
