Mechanical cause for acute left lung atelectasis after neonatal aortic arch repair with arterial switch operation: Conservative management.

ABSTRACT: Respiratory complications due to mechanical obstruction of the airways can occur following pediatric cardiac surgery. Clinically significant intrathoracic vascular compression of the airway can occur when extensive dissection and mobilization of arch and neck vessels is involved as in repair of interrupted aortic arch. This case report describes a neonate who underwent interrupted aortic arch repair along with an arterial switch operation and developed a left lung collapse immediately after tracheal extubation. Fiber-optic bronchoscopy revealed vascular compression as the real culprit. The child was successfully managed conservatively.

Favorable long-term outcomes in hospital survivors of a neonatal arterial switch operation

Project description:Objectives To assess long-term survival and reoperation-free survival after the arterial switch operation (ASO) and analyze the outcomes of reoperations after hospital discharge. Methods This was a single-institution retrospective study of 476 hospital survivors of ASO since August 1982. Preoperative diagnoses included 286 transpositions of the great arteries with intact septum, 143 transpositions with ventricular septal defect, and 47 double outlet right ventricles. There were 236 neonatal ASOs, 30 aortic arch repairs, 22 concomitant left ventricular outflow tract obstruction reliefs, 16 preoperative mild pulmonary regurgitations, and 13 intramural coronary arteries. Results During a median follow-up of 21.1 years (range, 0.1-39.2 years), 25 late deaths (5.3%) and 91 reoperations in 69 patients (14.5%) were noted. The reoperations included 44 left-sided reoperations in 34 patients (7.1%), 35 right-sided reoperations in 30 patients (6.3%), and 12 other reoperations in 12 patients (2.5%). Among the 69 patients who underwent reoperation, those with left-sided reoperations had lower survival at 15 years after reoperation compared to those with non–left-sided reoperations (91.2% vs 100%; P = .015; log-rank, 5.9). Multivariable analysis identified non-neonatal ASO, preoperative pulmonary regurgitation, intramural coronary artery, aortic arch repair, and concomitant left ventricular outflow tract obstruction relief as risk factors for left-sided reoperations. Reoperation-free survival was significantly higher in neonatal ASO compared with non-neonatal ASO (89.2% vs 75.2% at 20 years; P < .001; log-rank, 13.4). Conclusions Hospital survivors of neonatal ASO had favorable long-term outcomes. Video Abstract

Long term behavioural outcome after neonatal arterial switch operation for transposition of the great arteries.

Project description:AIMS: To evaluate behavioural outcome and quality of life in children aged 8-14 years after neonatal arterial switch operation for transposition of the great arteries. METHODS: Sixty children operated as neonates with combined deep hypothermic circulatory arrest and low flow cardiopulmonary bypass were evaluated at age 7.9-14.3 years by the Child Behaviour Checklist (CBCL) and the Inventory for the Assessment of the Quality of Life in Children and Adolescents (IQCL). RESULTS: Parent reported behavioural outcome on all CBCL problem and competence scores was worse, whereas quality of life on self reported IQCL scores was not reduced compared to the normal population. On multivariate analysis, severe preoperative hypoxia was related to parent reported social problems; peri- and postoperative cardiocirculatory insufficiency was associated with internalizing, externalizing, attention, and total behavioural problems. Reduced expressive language was associated with total behavioural problems, and poor academic achievement was related to parent reported deficits in school performance. Impaired neurological status and reduced endurance capacity both predicted self reported stress by illness. CONCLUSIONS: The neonatal arterial switch operation with combined circulatory arrest and low flow bypass is associated with parent reported long term behavioural impairment, but not with self reported general reduction in quality of life. This discrepancy may be a result of different perception of illness. In our experience, increased risk of long term psychosocial maladjustment after neonatal corrective cardiac surgery is related to the presence of neurological impairment and reduced endurance capacity.

Total arch replacement versus hybrid operation for aortic arch aneurysm in elderly patients: a retrospective cohort analysis.

Project description:BackgroundThere is not sufficient evidence of the superiority of hybrid procedures over total arch replacement (TAR) for the aortic arch aneurysm of an elderly patients. This retrospective study aimed to compare total arch replacement and hybrid procedures for treatment of aortic arch aneurysms in patients aged ≥75.MethodsThis study was a multicenter retrospective investigation of peri-operative outcomes of patients undergoing aortic arch aneurysm repair using either TAR or hybrid procedures between January 2012 and May 2021. Risk factors for mortality were evaluated using multivariate analyses.ResultsThis study included 90 patients, of which 28 underwent hybrid procedures (hybrid group: frozen elephant trunk =9, zone 0 =6, zone 1 =1, zone 2 =12), and 62 underwent TAR (TAR group), and the mean duration of follow-up was 27.0±28.8 months. In patient characteristics, the incidence of chronic obstructive lung disease and chronic kidney disease in the TAR group was significantly higher than in the hybrid group, and other operative risk factors were not significantly different in both groups. No significant differences in the incidence of post-operative complications and mortality on hospitalization. Survival rates of both groups were not significantly different (P=0.31). However, re-intervention rates after aortic arch aneurysm repair were significantly higher in the hybrid group compared to the TAR group (freedom from re-intervention rates at 1, 3, 5 years: 100%, 93%, 93% in the TAR group, and 90%, 80%, 80% in the hybrid group, P=0.04).ConclusionsThere was no definitive evidence of the superiority of hybrid procedures over TAR, although the risk of re-intervention was higher in the former group. The surgical strategy for aortic arch aneurysms should be selected based on the patient's demographic and anatomical characteristics.

Prenatal diagnosis of a rare aortic arch anomaly with left aortic arch and right ductus arteriosus: Cross ribbon sign.

Project description:Here, we report a fetus with a rare aortic arch anomaly with left aortic arch and right ductus arteriosus, which has not been reported so far. In this condition, the aorta extends to the left of the trachea as in normal, while the ductus arteriosus extends to the right of the trachea and joins the descending aorta posterior to the trachea, with a cross-ribbon sign.

DiGeorge syndrome and anomalous right aortic arch with arch-on-arch and figure-of-eight configurations: Aortic sac maldevelopment and left brachiocephalic artery abnormal remodeling.

Project description:We report a 6-month-old female infant with deletion of chromosome 22q11.2 (DiGeorge/VFS TUPLE 1), normal atrial arrangement with concordant atrioventricular connection, pulmonary atresia, large subaortic ventricular septal defect, diminutive native pulmonary arteries, a characteristic weird-shape right aortic arch with arch-on-arch appearance and figure of 8 configuration. We presented the cardiac computed tomographic angiographic and cardiac angiographic features. Using Autodesk 3ds Max 2018 software, we explained and illustrated the speculative embryologic etiology of this bizarre aortic archanomaly with the extensive abnormal remodeling of the left brachiocephalic artery, based on a "five-embryonic aortic arches" concept. As to the best of the authors' knowledge, this is the first report of a genetically confirmed case of DiGeorge syndrome and an exceedingly rare type of right aortic arch anomaly with embryologic explanation according to the "five-embryonic-aortic-arches" concept. It seems that the constellation of pulmonary atresia, bizarreshaped right aortic arch due to abnormal development of the aortic sac, and abnormal remodeling of the left brachiocephalic artery may be strongly suggestive of DiGeorge syndrome.

The multiform sonographic spectrum of arterial duct in right aortic arch.

Project description:To study the different characteristics of arterial duct (AD) in a series of prenatally detected right aortic arch (RAA). Out of 832 congenital heart diseases (CHD) referred to a tertiary center, 98 cases had RAA. Based on anatomical landmarks we identified 7 types of AD: type 1 left-sided, transverse; type 2 left-sided, vertical; type 3 from the underside of aortic arch (AA), vertical; type 4 right-sided, mirror-image "V", transverse; type 5 right-sided, "H" shaped, transverse; type 6 bilateral; type 7 absent or unidentifiable. For each type of AD the incidence of associated major CHD was calculated and chi-square test was applied to verify the null hypothesis with significance level of p < 0.05. Type 1 occurred in 43% of cases including 4 with CHD and no cases with pulmonary outflow obstruction (POO). Symptoms of vascular ring were present in 41% of survivors. Type 2, 3 and 7 AD were associated with tetralogy of Fallot (TOF) or equivalents. No type 5 AD with CHD had POO and 3 isolated cases had asymptomatic hypoplasia of left pulmonary artery (LPA). Two type 6 AD had disconnection of LPA. Type 1 occurred more often as an isolated finding (p < 0.001), whereas types 2 (p = 0.0026), 3 (p = 0.0045), 4 (p = 0.0325) and 7 (p = 0.0001) were frequently associated with major CHD. In RAA, type 1 (U-shaped) is usually an isolated finding (p < 0.001) which includes all symptomatic vascular rings. POO is always present when the AD is vertical or absent but not when it lies on a transverse plane. Bilateral AD is rare and brings the risk of functionary loss of left lung if not identified.
