Abstract:
Persistent left superior vena cava (PLSVC) is a rare anomaly of the systemic venous circulation. We report the case of a 22-year-old female that had history of multiple repair surgeries for her esophageal atresia, as well as a right lobectomy for bronchiectasis 15 years prior. She was admitted to the surgical ward for complete resection of the right lung. A trans-thoracic echocardiography was performed as part of the pre-surgical work-up and it revealed a dilated coronary sinus which led us to suspect the presence of a PLSVC. The latter was confirmed by a simple "Bubble study" and confirmed by CT angiogram. We will discuss throughout this paper, the clinical and radiological features, as well as the embryology of this anomaly, so that the knowledge of the existence of this anatomical variant, especially if surgery or catheterization is at reach of the medical team, may lead to avoid serious complications.

01:11Overview of Systemic Veins
The coronary sinus, the heart's principal vein, resides in the coronary sulcus on the heart's posterior aspect. This broad venous channel receives nearly all venous blood from the myocardium, the heart muscle. It is fed by three primary veins: the great cardiac vein, the...
01:19Veins of Thorax
The azygos vein, positioned just right of the midline and anterior to the vertebral column, begins at the junction of the right ascending lumbar and subcostal veins, terminating in the superior vena cava. This vein drains blood from the right side of the thoracic wall, thoracic viscera, and posterior abdominal wall.

The inferior vena cava is fed by numerous smaller veins. The lumbar veins, for instance, drain the posterior abdominal wall, emptying both directly into the inferior vena cava and into the...

Jugular Venous Pressure (JVP) Measurement
Position the patient at a thirty- to forty-five-degree angle or in a semi-fowler's position. Look for the highest point of pulsation in the internal jugular vein and measure the vertical distance to the angle of Loius or sternal angle. A normal JVP is 3-4 cm above...
