[Transvenous digital subtraction angiography of the thoracic aorta after surgical correction of isthmic stenosis].
25 patients (normotensive n = 19, hypertensive n = 6) underwent DSA control following corrective surgery of a coarctation of the thoracic aorta to exclude vascular complications. Simultaneously pressure gradients were determined between upper and lower extremities using the doppler-sonography. DSA was diagnostic in all patients. 2 cases showed a patch-dependent dilatation, in 1 case an anastomotic aneurysm could be demonstrated. In 6 patients with hypoplastic aortic arch and 2 patients with a slight reduction of the diameter in the anastomotic region a pathological pressure-gradient was measured. In these patients the ratio of aortic arch rsp. anastomosis/descending aorta was reduced in diameter (less than 0,66) and area (less than 44). Hypertension could not be related to pressure gradients or vascular disorders.
