Repair technique for a rare partial anomalous pulmonary venous return associated with retroaortic innominate vein

Background Retroaortic innominate vein (RIV) is a rare vascular abnormality. Although RIV itself is asymptomatic, its presence in patients with partial anomalous pulmonary venous return (PAPVR) to the superior vena cava (SVC) is surgically challenging because a simple Warden procedure is impossible. Case presentation A 16-year-old girl was diagnosed with tetralogy of Fallot, secundum, and sinus venosus atrial septal defect (ASD) at birth. She underwent total correction of tetralogy of Fallot and ASD closure at the age of 14-months. However, the diagnosis of PAPVR was missed. At the age of 16, she developed dyspnea on exercise. Echocardiography demonstrated severe pulmonary regurgitation, mild tricuspid regurgitation, and D-shaped left ventricle with paradoxical septal motion along with RIV and sinus venous ASD. Computed tomography confirmed RIV and PAPVR. Systemic and pulmonary venous blood pathways were separated by bovine pericardial patch, and pulmonary valve replacement was performed. Postoperative echocardiography demonstrated improvement of D-shaped left ventricle and laminar flow through the SVC and pulmonary veins. Postoperative computed tomography showed a well-reconstructed SVC and pulmonary venous pathway without stenosis. After an uneventful postoperative course, patient was discharged. Conclusions PAPVR in patients with RIV may be surgically challenging to repair. We report the first case of successfully repaired PAPVR associated with RIV.

Incidental retroaortic innominate vein in a patient with acute aortic dissection

Background Retroaortic innominate vein is a rare anomaly. It has been reported in patients with congenital anomalies such as Tetralogy of Fallot or right aortic arch. However, isolated retroaortic innominate vein is quite rare. Case presentation A 63-year-old man was transferred to our institution because of Stanford type A acute aortic dissection. Incidentally, we noticed that the left innominate vein coursed under the aortic arch and was directed into the superior vena cava on computed tomography. We performed emergent hemiarch replacement. Conclusions Attention must be paid to the cannulation site for venous uptake and the method of myocardial protection.

Isolated retroaortic innominate vein and right aortic arch: a case report and review of literature

Retroaortic course of left innominate vein is a rare venous anomaly which is usually associated with CHD. Isolated retroaortic innominate vein is exceedingly rare with only a handful of reported cases. We report an otherwise healthy newborn with isolated retroaortic innominate vein and right aortic arch, a combination which has previously not been reported.

Retroaortic innominate vein in a patient with transposition of the great arteries: the surgical implications

We describe the case of a newborn infant with transposition of the great vessels and a retroaortic innominate vein. This is a previously undescribed association. The decision was made to incorporate the retroaortic innominate vein into the Lecompte procedure at the time of surgery to avoid the risk of superior caval vein syndrome.
