Abstract
Interrupted Inferior Vena Cava (IVC) Syndrome, a rare congenital anomaly,
poses diagnostic and management challenges. This case study details a 46-
year-old male presenting with chest pain, exertional left arm pain, lower
limb swelling, and abdominal discomfort. Contrast-enhanced CT and CT
angiography revealed a suprarenal IVC interruption with azygos vein
continuation and collateral venous network. Timely recognition of such
anomalies is crucial, highlighting the importance of interdisciplinary
collaboration and potential surgical interventions for optimal patient care.
Interrupted Inferior Vena Cava Syndrome, an exceptionally rare congenital
anomaly, demands a nuanced approach for accurate diagnosis and effective
management. This case study contributes to the literature by detailing a
patient's clinical history, imaging findings, and management approach.
Recognition is essential, particularly when symptoms include lower limb
swelling and abdominal discomfort, as illustrated in this case. Advanced
imaging, specifically CT angiography, plays a key role in the diagnostic
journey. The case report delves into the embryological basis, clinical
implications, and collaborative efforts required for managing interrupted
IVC. A 46-year-old male presented with chest pain, exertional left arm pain,
lower limb swelling, and abdominal discomfort. Contrast-enhanced CT
angiography revealed a suprarenal IVC interruption with azygos vein
continuation and a complex collateral venous network.
Proximal abdominal scans lacked IVC images, but dilation of azygos and
hemi-azygos veins, thickening of diaphragmatic crura, and collateral vessels
suggested azygous continuation with IVC interruption. Management
options, including surgery, were discussed, with follow-up involving clinical
assessment and monitoring for complications.
Recognizing Interrupted IVC Syndrome is crucial in unexplained lower limb
swelling. This case underscores the significance of interdisciplinary
collaboration for accurate diagnosis and optimal patient management.
