[Coarctation of the thoracic aorta with extensive segmental hypoplasia. A new surgical approach (author's transl)].

The authors describe a new surgical technique used for the repair of coarctations of the aorta with extensive segmental hypoplasia. The technique is divided into four stages: enlargement of part of the hypoplastic segment by arterioplasty, using a flap from the subclavian artery; the extent of possible enlargement is governed by the length of subclavian artery available; resection of the residual hypoplasia and of the coarctation area proper; end-to-end anastomosis of the two aortic segments; revascularization of the arm by direct implantation of the subclavian artery into the left common carotid artery.

Tandem coarctation of the thoracic aorta. An unusual congenital anomaly.

The coarctation involving the aortic isthmus, with hypoplasia of the upper aortic segment, was satisfactorily repaired in a 15-year-old girl. The technique used was subclavian flap arterioplasty followed by reimplantation of the distal subclavian artery into the left carotid artery. Suprisingly weak femoral pulses were noted postoperatively and prompted a control angiogram. This showed an intraluminal diaphragm 2 cm below the site of the previous repair, with a 100 mm Hg gradient. At reoperation, a centrally performed fibrous diaphragm was excised, and the aorta was enlarged with a small Dacron patch. The postoperative course was uneventful.

Reoperation for massively calcified pulmonary valve heterografts. Surgical considerations.

Calcifications of pulmonary valve heterografts inserted in children are more frequently recognized with increasing follow-up periods and may lead to reoperation. This complication is common with our non-industrially prepared procine valves and may also be observed with Hancock porcine heterografts. Reoperation is rendered difficult by incrustation of the massively calcified heterograft into the posterior aspect of the sternum and because of the need of adequate exposure of the pulmonary bifurcation. Four patients were successfully reoperated on by the authors. The valves were not replaced. An improved surgical technique used in the last three cases is described.
