Abstract

La persistance de la veine cave supérieure gauche (PVCSG) est une malformation congénitale rare et bénigne. Elle est souvent asymptomatique et sa découverte est dans la majorité des cas fortuite. Nous rapportons le cas d'un enfant chez lequel on découvre cette anomalie suite à une perte de connaissance. S.M, âgé de 9 ans, sans antécédents pathologiques notables, admis pour perte de connaissance de durée brève, sans mouvements anormaux toniques ou cloniques. L'examen physique à son admission est normal. L’électrocardiogramme est sans anomalies. La radiographie du thorax a montré un arc moyen gauche en double contour. Le Holter rythmique a montré des signes d'hyperréactivité vagale. L’échocardiographie trans-thoracique (ETT) a mis en évidence une dilatation nette du sinus coronaire et a éliminé la présence d'une cardiopathie. Une angio- IRM cardiaque a confirmé le diagnostic de PVCSG. Par ailleurs l'aorte thoracique a été normale dans ces différents segments.

Persistent left superior vena cava: a case report and review of literature

Sandeep Goyal, Sujeeth R Punnam, Gita Verma … (2008)

Persistent left superior vena cava is rare but important congenital vascular anomaly. It results when the left superior cardinal vein caudal to the innominate vein fails to regress. It is most commonly observed in isolation but can be associated with other cardiovascular abnormalities including atrial septal defect, bicuspid aortic valve, coarctation of aorta, coronary sinus ostial atresia, and cor triatriatum. The presence of PLSVC can render access to the right side of heart challenging via the left subclavian approach, which is a common site of access utilized when placing pacemakers and Swan-Ganz catheters. Incidental notation of a dilated coronary sinus on echocardiography should raise the suspicion of PLSVC. The diagnosis should be confirmed by saline contrast echocardiography.

Persistent left superior vena cava with absent right superior vena cava: a case report and review of the literature

ÖZGÜL UÇAR, HÜLYA ÇİÇEKÇİOĞLU, İBRAHİM KOCAOĞLU … (2010)

Summary We report on a rare case of persistent left superior vena cava (PLSVC) with absent right superior vena cava (RSVC), an anomaly that is also known as isolated PLSVC. This venous malformation was identified incidentally in a 30-year-old woman during thoracic multi-detector computed tomography (MDCT), which was performed with the suspicion of intra-thoracic malignancy. On thoracic MDCT, the RSVC was absent. A bridging vein drained the right jugular and right subclavian veins and joined the left brachiocephalic vein in order to form the PLSVC, which descended on the left side of the mediastinum and drained into the right atrium (RA) via a dilated coronary sinus (CS). The patient was referred to the cardiology department for further evaluation. Transthoracic echocardiography revealed a dilated CS, and agitated saline injected from the left or right arms revealed opacification of the CS before the RA. The patient had no additional cardiac abnormality. Isolated PLSVC is usually asymptomatic but it can pose difficulties with central venous access, pacemaker implantation and cardiothoracic surgery. This condition is also associated with an increased incidence of congenital heart disease, arrhythmias and conduction disturbances. A wide spectrum of clinicians should be aware of this anomaly, its variations and possible complications.

The Incidental Finding of a Persistent Left Superior Vena Cava: Implications for Primary Care Providers—Case and Review

Loren Garrison Morgan, Jonathan Gardner, Joe Calkins (2015)

Persistent left superior vena cava (PLSVC) is the most common thoracic venous anomaly and is a persistent congenital remnant of the vena caval system from early cardiac development. Patients with congenital anomalous venous return are at increased risk of developing various cardiac arrhythmias, due to derangement of embryologic conductive tissue during the early development of the heart. Previously this discovery was commonly made during the placement of pacemakers or defibrillators for the treatment of the arrhythmias, when the operator encountered difficulty with proper lead deployment. However, in today's world of various easily obtainable imaging modalities, PLSVC is being discovered more and more by primary care providers during routine testing or screening for other ailments. Given the known association between anomalous venous return and the propensity for cardiac arrhythmias, we review the embryology of PLSVC and the mechanisms by which it leads to conduction abnormalities. We also provide the practitioner with recommendations for certain baseline cardiac observations and suggestions for proper surveillance in hopes that better understanding will reduce unnecessary and potentially harmful testing, premature subspecialty referral, and unneeded patient anxiety.
