In all patients we carried out complete catheterization of the right heart after introduction of the catheter percutaneously through the femoral vein by the Seldinger technique, and in children up to age 2 years, after surgical preparation of the saphenous vein. In 15 children only the venous route was used for cardiac catheterization without touching the femoral artery. However, in the majority of cases the femoral artery was involved. In 31 children , the femoral artery was only cannulated for the purpose of sampling arterial blood and measuring pressure. Puncture of the femoral artery in children younger than 1 year was carried

The reported incidence of disturbances in blood flow in the peripheral arterial bed after catheterization and angiography of the arterial system range from 0% to 100’Yo [1-9]. The principal cause of this scatter is differences in the manner of determining such complications and their evaluation. Clinical investigation reveals only very crude disturbances of arterial patency. More sensitive methods include oscillometry [1 5, 9-12] or the Doppler technique [12]. A more objective evaluation of disturbances in function which result from puncture catheterization or angiography is measurement of blood flow in the involved extremity [10-12]. Plethysmographic methods after catheterization have shown a significant decrease in blood flow to the calf, increased resistance, and decreased venous blood volume. Repair to these changes took about 1 week [10]. Unfortunately, measurement limited to resting blood flow does not reveal slight disturbances in blood supply [13-15] or inadequate blood supply during periods other than resting conditions. We studied late disturbances in peripheral blood flow resulting from catheterization. The method allowed us to measure this parameter in any selected muscle, not only at rest but also with increased muscle demands on the blood supply. The investigated group included only those patients with congenital heart defects or with severe respiratory disease, in whom catheterization and angiocardiography had been carried out in childhood and in whom clinical investigation and, in suspect cases, oscillometry had not revealed any disturbance of blood

flow to the lower extremity following the investigation. Because of discordant views on the incidence of complications related to arterial catheterization technique, we attempted to evaluate differences between the two basic technical approaches percutaneous Seldinger technique and surgical insertion of the catheter. Two further subgroups were formed by patients in whom left heart catheterization was carried out transseptally and the femoral artery was not involved or only cannulated to

Cardiac

In 99 patients with congenital heart defects or chronic respiratory disease without clinical symptoms of disturbances in peripheral circulation, resting and maximal blood flow in the anterior tibial muscle of both extremities were investigated 2.7 years (average) after cardiac catheterization. The method used involved ‘“Xe clearance. Resting blood flow was normal and no difference could be demonstrated between the extremity originally used for catheterization and the contralateral control extremity.
