Abstract
Superior vena caval obstruction following Mustard repair of d-transposition of the great arteries is usually relieved by partial or complete revision of the intra-atrial repair. We employed a different approach in a patient with isolated total obstruction of the superior vena caval pathway, who suffered from fatigue, venous congestion in the upper part of the body and mild hydrocephalus. A 12 mm polytetrafluoroethylene tube was interposed between the left innominate vein and the left (functionally right) atrial appendage. Early and medium-term relief was demonstrated by repeat catheterization of the right heart and computed tomography brain scan three months postoperatively. The rationale for use of prosthetic material in the venous system is discussed and the need for long-term follow-up is stressed.
