Abstract

Middle aortic syndrome is a rare cause of renovascular hypertension in infants. We report a 21-month-old boy weighing 11 kg who presented with severe systemic hypertension (205/117 mmHg) and left ventricular (LV) dysfunction due to diffuse hypoplasia of the thoracoabdominal aorta. Echocardiography and computed tomography angiography showed two coarctation segments involving the superior mesenteric and renal arteries without inflammatory signs. After medical stabilization, acute pulmonary edema and cardiogenic shock developed. A hybrid transabdominal approach with sequential covered-stent implantation achieved favorable recovery, with normalization of blood pressure and improvement in LV function.
