Persistent Left Superior Vena Cava Demonstrated With Multislice Spiral Computed Tomography

Persistent Left Superior Vena Cava

Persistent left superior vena cava

Persistent left superior vena cava (PLSVC) is the most common congenital malformation of thoracic venous return and is present in 0.3 to 0.5% of individuals in the general population. This heart specimen was dissected from a 35-year-old male cadaver whose cause of death was determined as non-cardiac. The heart was examined and we found a PLSVC draining into the coronary sinus. The right superio...

A persistent left superior vena cava.

Persistent left superior vena cava is the most common form of anomalous venous drainage involving the superior vena cava, and represents persistence of the left horn of the embryonic sinus venosus, which normally involutes during normal development to become the coronary sinus. Almost always, a persistent left superior vena cava enters the right atrium through the orifice of an enlarged coronar...

A case of persistent left superior vena cava with absent right superior vena cava draining into dilated coronary sinus: magnetic resonance imaging and computed tomography findings

Conclusions Although PLSVC is usually asymptomatic, it is important to be aware of its existence, since it may cause problems performing central venous catheterization, pacemaker implantation and cardiothoracic surgery. This anomaly is also associated with high incidence of congenital heart disease, arrhytmias and conduction disturbances. Modern imaging techniques including computed tomography ...

Brain abscess with persistent left superior vena cava.

Persistent left superior vena cava (PLSVC) is the most common congenital cardiac anomaly occurring in around 0.4% of the general population, and 1.3-4.5% in those with additional cardiac defects. Eighty-two percent of PLSVC coexists with a right superior vena cava. Usually PLSVC is asymptomatic, but can cause difficulties during central venous cannulation from the left side. There are a few cas...
