The aim of the study was to evaluate the effect of a conventional pressure dressing on arterial and venous blood flow of the legs after cardiac catheterization. ⋯ A conventional pressure dressing caused a significant reduction of arterial as well as venous blood flow of both the punctured leg and the contralateral leg. This is of clinical relevance especially in patients with known peripheral arterial disease or patients at risk for deep venous thrombosis.

Due to the increasing number of diagnostic heart catheterizations, especially in elderly patients, as well as the increase of percutaneous transluminal coronary angioplasties, we are confronted with a rise in peripheral complications evolving from difficulties in the procedure of the puncture of the femoral artery or vene. The development of greater hematomas in the area of the puncture, the formation of arterio-venous fistulas and aneurysma spuria are the foremost complications. It was the aim of the study to investigate in as far an improved puncture technique could reduce the rate of peripheral complications. ⋯ The number of patients with hematomas with diameters of more than 5 cm was twice as high in the conventionaly punctured group (28%) than in the "Smart Needle" group (14%). However, patients suffering from arterial hypertension or hemostatic disorders showed an increased risk of vascular complications. In regard to the cost-benefit relation an indication for the use of the new technique is to be seen especially in overweight patients and patients suffering to aortic stenosis or cardiogenic shock.
