Subclavian artery pseudoaneurysm long after the division of modified Blalock –Taussig shunt

AbstractA massive but asymptomatic left subclavian artery pseudoaneurysm was diagnosed in a 30-year-old female patient with transposition of the great arteries, ventricular septal defect, and pulmonary atresia. After undergoing bilateral modified Blalock –Taussig shunts at the age of 4 months and 3 years, respectively, she underwent the Rastelli operation and division of both shunts at the age of 6 years of age. The pseudoaneurysm was not discovered at the follow-up investigation at age 14. During the time period from age 18 to 30 years, she w as lost to follow-up, she was confirmed to be free from infectious disease, traumatic accident, or vasculitis. Pregnancy-induced hypertension was not associated during her pregnancy. Graft replacement of the left subclavian artery and redo right ventricular outflow tract reconstruction were successf ully performed under deep hypothermic circulatory arrest at the age of 33 years.
