ABSTRACT: Coarctation of the aorta refers to a narrowing of the aortic artery that causes an obstruction to flow distal to the origin of the left subclavian artery, at the origin of the ligamentum arteriosus.
A 14-year-old male patient admitted to the emergency department with an increase in blood pressure of 190/100, asymptomatic. Renal Doppler ultrasound is indicated due to suspicion of arterial hypertension of renal origin. Doppler ultrasound is performed with assessment of renal and aortic flows, determining tardus parvus in all the assessed trajectories, generalized decrease in resistance indices and loss of triphasic morphology of the abdominal aorta, angiotomography with protocol is suggested for thoracic aorta. Tomography angiography was performed with a protocol for the thoracic aorta, diagnosing aortic coarctation. He was taken to the hemodynamics room where an aortic stent was placed, he went to intensive care for two days with satisfactory evolution and was later admitted to the floor, with blood pressure management within normal limits.
