Insights
This case study details a rare finding of both double superior and inferior vena cava in a patient with cardiac conditions. This unique anatomical variation required careful diagnosis and management during pacemaker procedures.
Area of Science:
- Cardiovascular Medicine
- Medical Imaging
- Anatomical Variations
Background:
- A 56-year-old woman presented with recurrent paroxysmal atrial fibrillation and sick sinus syndrome.
- Pre-pacemaker implantation, persistent left superior vena cava was diagnosed.
Observation:
- During pacemaker replacement, challenging lead progression from the right femoral vein suggested an inferior vena cava anomaly.
- Contrast ultrasonography and computed tomography confirmed a double inferior vena cava.
Findings:
- The patient exhibited the rare, isolated, and contemporary presence of both double superior vena cava and double inferior vena cava.
- This represents the first reported case of this specific combined anatomical variation.
Implications:
- Highlights the importance of recognizing rare venous anomalies in cardiovascular interventions.
- Accurate pre-procedural imaging is crucial for managing patients with complex congenital venous variations.
- Understanding these anomalies aids in successful pacemaker lead placement and patient care.
Abstract:
We report the case of a 56-year-old woman affected by recurrent paroxysmal atrial fibrillation and sick sinus syndrome. Before pacemaker implantation, a diagnosis of left superior vena cava persistency was made. After some years, at pacemaker replacement, an inferior vena cava anomaly was suspected because of the difficult progression of the lead for temporary pacing from the right femoral vein. Contrast ultrasonography strongly suggested the presence of a double inferior vena cava. The diagnosis was further confirmed by contrast computed tomography. To the best of our knowledge, this is the first description of the isolated contemporary presence of double superior and inferior venae cavae.

Veins of the Abdomen and Pelvis
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...
Overview 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 middle...
Overview of Systemic Arteries
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 heart.
Veins 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.
