[Short- and long-term problems in dilatation of untreated aortic isthmus stenosis in children].
We examined problems and complications during and after balloon dilation of native coarctation of the aorta in 31 children with a mean age at first dilation of 5.77 +/- 5.4 years (0.08-16 years), who had a total of 37 balloon dilations. Twenty-six patients were restudied 3 to 24 months after the first procedure. In six patients, because of recoarctation, further dilations were performed. In two patients the second procedure was not successful and they required surgery. In 14/37 (37.8%) dilations the routine sedation was insufficient. The retrograde catheter could be introduced percutaneously in all but one patient. Because of small femoral arteries the introduction of the balloon catheter was not possible in three cases (8.1%). In three more patients (8.1%) the adequate catheters were not in stock. Complications included: transfusion because of blood loss in six patients (16.2%), chest pain in three (8.1%), rupture of balloon in three (8.1%), thrombectomy in three (8.1%), and partial reopening of ductus arteriosus in one patient. Duration of hospital stay was a mean of 1.81 days +/- 1.65 (range 1-9 days). Ninety percent of the patients were discharged within 2 days. On follow-up (range: 3-50 months), eight patients (21.6%) had a weak femoral pulse, of whom only one had an absent pulse, eight patients (21.6%) had paradoxical hypertension despite good dilation and no significant gradients, and only one patient showed a small aneurysm. We conclude that balloon angioplasty of native coarctation is a successful and relatively safe method of treatment of native coarctation. The most serious complication is arterial occlusion of the affected leg.(ABSTRACT TRUNCATED AT 250 WORDS)
