PEREZ-WULFF, Juan et al. Ultrasound-guided laser photocoagulation for the treatment of fetal bronchopulmonary sequestration. Report of two successful cases in Venezuela.

Bronchopulmonary sequestration is a malformation of the respiratory system consisting of non-functioning bronchial and pulmonary tissue, separated from the tracheo-bronchial tree and fed by a blood vessel from the systemic circulation. The incidence is 1 in 5000 births, ranging from 0.15% to 6.45% of pulmonary pathologies. The prognosis is generally favorable, with spontaneous regression of the lesion reported in 50% to 75% of patients. It can cause mass effect, compressing the heart and lung to the point of generating hemodynamic changes and heart failure. There are multiple procedures for treatment and management, mainly in large cases and hydropic fetuses, to improve perinatal prognosis. We present the first two cases of bronchopulmonary sequestration treated in Venezuela by laser photocoagulation of the nutrient vessel and their perinatal evolution, with 100% survival and without any complications recorded in the perinatal period.
