Anterior Translocation of the Right Pulmonary Artery for Relief of Airway Compression in the Repair of Distal Aortopulmonary Window and Interrupted Aortic Arch

Berry syndrome-a rare congenital cardiac anomaly

Berry syndrome is a rare congenital cardiac anomaly, characterized by distal aortopulmonary window, hypoplasia or interruption of the aortic arch, intact ventricular septum, and aortic origin of the right pulmonary artery and patent ductus arteriosus. Anatomic depiction of each component is important for the diagnosis. Single-stage surgical repair is challenging but feasible with good survival outcomes. The available literature on this anomaly is limited. Hence, this paper aims at reviewing the literature on Berry syndrome.

Surgical repair for aortopulmonary window with interrupted aortic arch in late childhood

Aortopulmonary window with interrupted aortic arch is rarely reported beyond infancy. Pre-operative assessment and surgical repair are challenging. We report successful surgical repair of aortopulmonary window with interrupted aortic arch in a 6-year-old girl with near-normal pulmonary artery pressure immediately following surgery.

Relief of Anteriorly Translocated Pulmonary Artery Compression With a Nuss Bar

A concomitant anterior translocation of the right pulmonary artery (RPA) can be used in patients with airway compression by a dilated RPA associated with congenital heart disease having a large left-to-right shunt or aortic arch anomaly. However a chest wall deformity and mechanical compression of the anteriorly translocated RPA could develop after the operation. In this situation simple RPA angioplasty is not sufficient. Therefore we adopted a technique to perform a concomitant Nuss procedure in an effort to resolve this problem. After 8 months of follow-up a widely patent RPA and a normal appearance of the chest wall were confirmed.

Airway Improvement with Medium-Term Compression Duration after Right Pulmonary Artery Anterior Translocation

Left main bronchus compression occasionally occurs in patients with cardiac disease. A 19-month-old female patient weighing 6.7 kg was admitted for recurrent pneumonia and desaturation. She had an a trial septal defect (AS D) with a right aortic arch. Her left main bronchus had been compressed between the enlarged right pulmonary artery (RPA) and the descending thoracic aorta for 14 months. We conducted ASD closure and RPA anterior translocation via sternotomy. The left main bronchus compression was relieved despite the medium-term duration of compression.

Current outcomes of one-stage surgical correction for Berry syndrome

OBJECTIVES

Berry syndrome is a combination of distal aortopulmonary window (APW), aortic origin of the right pulmonary artery (RPA), intact ventricular septum, and interrupted aortic arch. We present here our current experience of primary repair of this syndrome with the goal of optimizing treatment for this rare condition.

METHODS

From January 2003 through December 2015, 16 infants with Berry syndrome underwent one-stage repair at Shanghai Children's Medical Center. Three different surgical correction techniques were used to repair the APW and aortic origin of the RPA, including intra-aortic baffle in 5, RPA detachment in 6, and RPA angioplasty with aortic cuff in 5 patients.

RESULTS

The median age at repair was 90.5 days (range, 8-170 days). The interrupted aortic arch morphology was type A in 14 and type B in 2 patients. The APW morphology was type IIa in 4, type IIb in 10, and type III in 2 patients. Hospital death occurred in 2 patients, and death at follow-up occurred in one other patient. Three patients who previously underwent RPA angioplasty with aortic cuff required reoperation for aortic or RPA stenosis. Freedom from reoperation was 84.8%, 75.4%, and 75.4%, respectively at 1, 5, and 10 years after surgery.

CONCLUSIONS

One-stage repair of Berry syndrome has achieved acceptable outcomes. Reoperations mainly are related to aortic or RPA stenosis, and the reoperation rate is higher when RPA arterioplasty is performed with an aortic cuff.
