Abnornal connection of the left partial pulmonary vein to the innominate vein: A clinical case and literature review

Abstract

Background: The left partial abnormal pulmonary venous connection is a very rare and easily missed congenital anomaly. If not handled properly, this defect can cause many serious disorders in the development of the child. Surgery to return the pulmonary vein to the left atrium is the solution to this situation.
 Methods: We report a case of a left partial abnormal pulmonary vein draining into the left innominate vein with a perimembranous ventricular septal defect that was diagnosed and operated on at the Pediatric Cardiovascular Surgery Department, Heart center, E hospital. In this case, we discuss methods of diagnosis, treatment, and review the medical literature on this abnormal form of pulmonary veins.
 Results: Female, 15 months old, history: second child, normal delivery, full-term, birth weight 3000g, no asphyxia, no cyanosis after birth; detected congenital heart from 30 weeks gestation. After birth, the child can eat, suckle, and have normal mental-motor development. Recently, the child ate poorly, had slow weight gain, went to the provincial hospital for examination, was transferred to E hospital's cardiovascular center. Ultrasound and cardiac catheterization detected perimembranous ventricular septal defect and left partial pulmonary vein abnormality. We performed a total surgical repair including patching the ventricular septal defect and transferring the pulmonary vein to the left atrium through the incision between the sternum. Postoperative echocardiography gave good results. The patient was discharged from the hospital 9 days after surgery.
 Conclusion: Surgery to transfer the pulmonary vein to the left atrium for the abnormality of the left partial pulmonary vein connection has good results.
