TÓM TẮT Mục tiêu: Đánh giá kết quả tạo hình quai động mạch chủ trong phẫu thuật một thì điều trị bệnh lý GĐQĐMC tại Bệnh Viện Nhi Trung Ương từ năm 2012 đến 2019. Phương pháp: Nghiên cứu hồi cứu 53 bệnh nhân được phẫu thuật sửa chữa một thì bệnh tim bẩm sinh GĐQĐMC từ tháng 01 năm 2012 đến tháng 12 năm 2019. Kết quả: Bệnh nhân gồm 32 nam và 21 nữ. Tuổi trung bình là 43 ± 53 ngày, cân nặng trung bình khi phẫu thuật 3.4 ± 0.7 kg. Trung bình thời gian chạy máy tim phổi nhân tạo (TPNT) là 128 ± 28 phút, thời gian cặp chủ 92 ± 18 phút và thời gian tưới máu não chọn lọc là 34 ± 11 phút. Tử vong sớm sau mổ có 9 bệnh nhân (16.9%). Thời gian theo dõi trung bình 37 ± 21 [8-95] tháng. Tỷ lệ sống sót chung sau phẫu thuật là 83% tại thời điểm 8 năm. Tỷ lệ sống sót không phải can thiệp lại do tái hẹp quai ĐMC là 97.6% tại thời điểm 8 năm, không có bệnh nhân tử vong trong quá trình theo dõi. Kết luận: Phẫu thuật một thì sửa chữa bệnh lý GĐQĐMC ở Bệnh viện Nhi Trung ương là hoàn toàn khả thi và có thể thực hiện được ở lứa tuổi sơ sinh và nhũ nhi với tỷ lệ tử vong thấp. Từ khóa: Gián đoạn quai động mạch chủ, thông liên thất, hẹp đường ra thất trái, cửa sổ chủ phế. ABSTRACT OUTCOMEOF SURGICAL REPAIR FOR INTERRUPTED AORTIC ARCH IN NATIONAL CHILDREN’S HOSPITAL, HANOI Objective: The objective was to determine outcomes of aortic arch reconstruction in one-stage repair of interrupted aortic arch in Nation Hospital of Pediatrics from 2012 to 2019. Methods: Records of 53 consecutive patients undergoing interrupted aortic arch repair between January 2012 to December 2019 were reviewed. Single-stage repair was performed in all of the patients. Results: The patients consisted of 32 males and 21 females. Mean age of the patients was 43 ± 53 days and mean weight was 3.4 ± 0.7 kg. The average cardiopulmonary bypass time was 128 ± 28 minutes, the aortic cross-clamp time was 92 ± 18 minutes and the selective cerebral perfusion time was 34 ± 11 minutes. Early mortality was 16.9%. Mean follow-up was 37 ± 21 [8-95] months. Actuarial survival including early death was 83% at 8 years. The freedom from reintervention of recurrent aortic arch obstruction was 97.6% at 8 years. No late death occurred. Conclusions: Single-stage repair of interrupted aortic arch with intracardiac defects is safe and feasible with newborn and infant in National Hospital of Pediatrics.

AbstractA 6-day-old male with interruption of the aortic arch at the isthmus (type A) had the typical phenotype of DiGeorge syndrome. There was also a doubly committed juxta-arterial ventricular septal defect and an unobstructed left ventricular outflow tract. Hypoplasia of the thymus was confirmed during a modified Blalock-Park operation. He had persistent hypocalcemia, and was susceptible to infection. He was subsequently revealed by the use of fluorescence in situ hybridization analysis to have 22q11.2 deletion. Interruption of the aortic arch at the isthmus is presumed to reflect abnormal fetal hemodynamics, and is considered a distinct pathogenetic entity from interruption between the left common carotid and subclavian arteries, the latter being the variant more frequently associated with DiGeorge syndrome. In our case, the 22q11.2 deletion likely played a major role in the etiology of the interrupted aortic arch.

Objectives Interrupted aortic arch (IAA) includes a broad spectrum of associated anomalies. In this study, we present our surgical management and patient-specific decisions regarding IAA anomalies with early- and mid-term outcomes. Methods The medical records of 25 patients undergoing IAA repair between 2014 and 2019 were retrospectively reviewed. Sixteen patients had type B (64%) interruptions, 7 had type A (28%) interruptions, and 2 had type C (8%) interruptions. Fourteen patients had an isolated ventricular septal defect, and 3 of them had associated left ventricular outflow tract obstruction. Other associated anomalies were functional single ventricle (n = 5), Taussig–Bing anomaly (n = 3), aortopulmonary window (n = 1), multiple ventricular septal defects (n = 1), and truncus arteriosus with dextrocardia (n = 1). The initial operation age was 17.2 ± 14 (range: 1 - 60) days. Results Single-stage total repair was performed for 15 patients. Six patients underwent aortic arch repair and pulmonary artery banding. Four patients with left ventricular outflow tract obstruction or who were premature underwent the hybrid procedure. The aortic arch repair was performed in 16 cases (64%) by the anterior patch augmentation technique, in 3 cases (12%) by the reverse left subclavian artery flap technique, and in 3 cases (12%) by direct end-to-end anastomosis. Postoperative early mortality occurred in 4 (16%) patients, and sternal closure was delayed in 13 (52%) patients. Three patients who underwent a hybrid procedure due to left ventricular outflow tract obstruction underwent biventricular repair 8 to 13 months later. Eight patients (38%) required reintervention due to arch restenosis during the follow-up period. The mean follow-up was 37.1 ± 21.7 months. Conclusion Planning surgical treatment according to the characteristics of the patients and accompanying anomalies may improve the results.
