Surgery for arteriovenous fistulas and dilated vessels in the right lung after the Glenn procedure
AM Van Den Bogaert-Van Heesvelde, F Derom, M Kunnen, H Van Egmond and A Devloo- Blancquaert
A superior vena cava-right pulmonary artery (SVC-RPA) anastomosis was
constructed in a 2-year-old boy with tetralogy of Fallot. Ten years later
and 5 years after "corrective" surgery without removal of the shunt,
cyanosis and heart failure developed. Stereocineangiography and lung
scanning revealed arteriovenous fistulas and dilated vessels in the right
lung. The SVC-RPA anastomosis was taken down, the SVC being reimplanted in
the right atrium and the RPA end being closed with a few stitches. Neither
lobectomy nor pneumonectomy was performed. Immediately after the operation
and during a follow-up period of almost 2 years, the boy has remained
asymptomatic. Whenever a correction is planned in a patient with SVC-RPA
anastomosis, the vessels of the right lung should be examined by scanning
and angiography. If important arteriovenous fistulas do exist, the affected
lung should be excluded from the pulmonary artery circulation.
