Summary
Persistent Left Superior Vena Cava (PLSVC), a rare vascular anomaly, is often asymptomatic but can cause arrhythmias. This case highlights PLSVC with an absent Right Superior Vena Cava, diagnosed during pacemaker implantation.
Area of Science:
- Cardiovascular Medicine
- Medical Imaging
- Congenital Anomalies
Background:
- Persistent Left Superior Vena Cava (PLSVC) is a rare congenital vascular anomaly with an incidence of 0.3-0.5% in the general population.
- It is typically asymptomatic and often discovered incidentally during medical procedures.
Observation:
- A 55-year-old female presented with complete heart block and sepsis.
- Diagnosis of isolated PLSVC (with absent Right Superior Vena Cava) was made during permanent cardiac pacemaker implantation and central venous catheter insertion.
- Abnormal pathways of the catheter and pacing leads were noted.
Findings:
- The case details an isolated Persistent Left Superior Vena Cava, a rare presentation.
- The anomaly was identified due to complications and procedural findings during pacemaker insertion.
Implications:
- PLSVC can have significant clinical implications, including an association with cardiac arrhythmias.
- Accurate diagnosis of PLSVC is crucial for guiding medical device placement and patient management.
- Understanding this anomaly is important for cardiovascular surgeons and interventional cardiologists.

The key difference between Superficial Vein Thrombosis (SVT) and Deep Vein Thrombosis (DVT) lies in their location and severity.Clinical ManifestationsSVT typically presents with localized pain, tenderness, and redness along the course of a superficial vein, often accompanied by a palpable, cord-like structure under the skin. This condition is usually less dangerous than DVT but can be uncomfortable and may lead to complications such as cellulitis or, rarely, a clot extension into the deep...

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 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...

Venous thrombosis, the most common disorder of the veins, involves the formation of a thrombus or blood clot associated with vein inflammation. It can be classified as either superficial vein thrombosis or deep vein thrombosis.Superficial Vein Thrombosis: This involves the formation of a thrombus in a superficial vein, usually the greater or lesser saphenous vein. Though less severe than deep vein thrombosis (DVT), SVT can lead to complications if untreated.Deep Vein Thrombosis (DVT): This...
