[Effect of a pressure dressing on angiologic complications after diagnostic coronary angiography].

500 consecutive patients undergoing diagnostic coronary angiography were studied for vascular complications using either a conventional (n = 250) or a special mechanical device for compression dressing (n = 250). In both groups one case of arterial occlusion occurred. Using the conventional pressure dressing, we observed four pseudoaneurysms, whereas there were none in the special mechanical device dressing group (p < 0.05). In contrast, eight patients developed a deep vein thrombosis after mechanical device pressure dressing compared to only 1 venoust in the conventional dressing group (p < 0.02). Five patients, four of the eight patients with mechanical device dressing, suffered from clinical apparent pulmonary embolism (p = 0.1801). Thus, a mechanical device pressure dressing may decrease the number of arterial pseudoaneurysms but is associated with an increased risk of deep vein thrombosis and pulmonary embolism. Therefore, we recommend the use of the mechanical device pressure dressing only in selected patients with severe obesity.
