A rare congenital extracardiac arteriovenous fistula was incidentally discovered in a patient evaluated for angina using computed tomographic coronary angiography. This case highlights a unique vascular anomaly.
Area of Science:
- Cardiovascular Medicine
- Radiology
- Vascular Surgery
Background:
- Congenital extracardiac arteriovenous fistulas are rare vascular malformations.
- Diagnosis often occurs incidentally during imaging for other conditions.
Purpose of the Study:
- To describe a case of incidentally discovered congenital extracardiac arteriovenous fistula.
- To illustrate the origin and trajectory of this rare vascular lesion.
Main Methods:
- Computed tomographic coronary angiography was performed for angina evaluation.
- Detailed imaging analysis was used to identify and characterize the fistula.
Main Results:
- An incidental finding of a congenital extracardiac arteriovenous fistula was made.
- The origin and course of the vascular lesion were delineated.
Conclusions:
- Congenital extracardiac arteriovenous fistulas can be incidentally detected during cardiac imaging.
- Awareness of such rare anomalies is crucial for accurate diagnosis and management.

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.

Development of the Lymphatic System
The first lymph sacs to form are the paired jugular lymph sacs located at the junction of the internal jugular and subclavian veins. From these sacs, lymphatic capillary plexuses extend to the thorax, upper limbs, neck, and head, eventually forming lymphatic vessels. Each jugular lymph sac maintains a...
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...
