A patch-graft technique for correction of pulmonic stenosis in dogs.
Pulmonic stenosis in 6 dogs were corrected surgically by means of a patch-graft technique, without using cardiac bypass or venous occlusion. Five of the 6 dogs have remained clinically normal for 4 to 40 months following surgery. The stenosis in 1 dog was inadequately repaired. The technique resulted in minimal blood loss, no mortality, and was easily adapted to the minimal size of several of the affected dogs. When performed correctly, the technique relieved the stenosis wherever it occurred (viz, supravalvular, valvular, subvalvular, infundibular, or any combination). The success of the procedure was determined, in part, by pre- and postoperative pressure measurements at the time of surgery, and by periodic physical, radiographic, and electrocardiographic examinations after surgery.
