Summary
Anatomical variations like an isolated persistent left superior vena cava can be incidentally found during imaging before procedures. Awareness is crucial for safe central venous catheter insertion, particularly from the right side.
Area of Science:
- Cardiovascular Imaging
- Anatomical Variations
Background:
- Catheter ablation is a common cardiac procedure.
- Central venous catheter insertion is frequently performed for various medical interventions.
Purpose of the Study:
- To highlight the importance of identifying an isolated persistent left superior vena cava (PLSVC).
- To emphasize the implications of PLSVC for central venous catheter placement.
Main Methods:
- Three-dimensional contrast-enhanced chest computed tomography (CT) was utilized.
- Anatomical variations were identified in a patient undergoing pre-procedural imaging.
Main Results:
- An isolated persistent left superior vena cava was incidentally discovered.
- This anatomical abnormality was noted in a patient scheduled for catheter ablation.
Conclusions:
- Identification of isolated PLSVC is critical before procedures requiring central venous access.
- Clinicians should be aware of this anomaly to prevent potential complications during catheter insertion from the right jugular or subclavian veins.

The human body is a complex system of interconnected parts, and the circulatory system plays a crucial role in maintaining overall health. One key component of this system is the inferior vena cava, a large vein responsible for returning blood from the abdominopelvic viscera and abdominal walls to the heart.
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...

The human body is a complex, well-organized machine, and at the heart of its operations lies the circulatory system. This network of blood vessels, which includes systemic arteries, plays a vital role in maintaining life by transporting nutrients, oxygen, and waste products to and from cells throughout the body.
Systemic circulation is the part of the cardiovascular system that carries oxygenated blood away from the heart to the body's tissues and returns deoxygenated blood back to the...

Systemic veins are crucial blood vessels that return deoxygenated blood from various body tissues back to the heart. There are three systemic veins that return deoxygenated blood to the heart, they are as follows.
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...

The azygos system is a crucial part of the body's circulatory system and drains most of the thorax. It comprises the azygos, hemiazygos, and accessory hemiazygos veins.
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 heart, an organ critical to survival, gets nourishment not from the blood it pumps but from a separate circulation system known as coronary circulation. This is the shortest circulation in the body and is responsible for supplying the heart with the nutrients it needs to function effectively.
Coronary circulation begins at the base of the aorta, where two main arteries arise—the left and right coronary arteries. These arteries encircle the heart in the coronary sulcus and supply the...

The systemic and pulmonary circuits are crucial components of the circulatory system, working together to transport blood between the heart, lungs, and the rest of the body. The process begins with pulmonary circulation, where deoxygenated blood is pumped from the right ventricle to the lungs via the pulmonary trunk and arteries. Upon reaching the lungs, the blood becomes oxygenated and returns to the heart, specifically to the left atrium, via the pulmonary veins.
