The use of "nonanatomic" pulmonary resection in infants with extensive congenital adenomatoid malformation of the lung.

In three infants with extensive congenital adenomatoid malformation of the lung, a method of nonanatomic pulmonary resection permitted preservation of small superiorly positioned pulmonary remnants. These remnants then demonstrated a surprising capacity for expansion, growth, and function during follow-up periods of 5 years, 9 months; 7 years, 6 months; and 19 years. Thus far, this small experience indicates that this method of management does not appear to entail greater short- or long-term risks than the alternative procedure of pneumonectomy.
