Insights
Abernathy malformations, rare congenital shunts, can cause serious metabolic and anatomical issues. Interventional radiology offers a minimally invasive approach for diagnosis and management, as demonstrated in a unique case.
Area of Science:
- Vascular Surgery
- Interventional Radiology
- Hepatology
Background:
- Abernathy malformations are congenital extrahepatic portosystemic shunts diverting portal blood away from the liver.
- These shunts can lead to metabolic derangements like hyperammonemia and hepatic encephalopathy, as well as anatomical issues such as varices.
- Interventional radiology is crucial for diagnosis and minimally invasive management of these conditions.
Observation:
- A rare case of a peripheral congenital portosystemic shunt was observed.
- The shunt connected the inferior mesenteric vein to the internal iliac vein.
- The patient presented with rectal bleeding.
Findings:
- The case highlights a unique anatomical variation of Abernathy malformation.
- Diagnostic and therapeutic interventions were successfully performed within the interventional radiology department.
- A holistic, minimally invasive approach was employed.
Implications:
- This case underscores the importance of interventional radiology in managing rare vascular anomalies.
- Minimally invasive techniques can reduce procedure time and hospital stays.
- Early diagnosis and management are key to preventing severe complications associated with portosystemic shunts.
Abstract:
Abernathy malformations are congenital extrahepatic porto-systemic shunts which allow splanchnic circulation to bypass the metabolic screen of the liver and drain directly into the systemic circulation. The resulting metabolic abnormalities have a multitude of implications ranging from hyperammonaemia, hepatic encephalopathy, to pulmonary hypoxemia. The shunt also causes anatomical implications in the form of varices. Interventional radiology plays the central role in this era of minimal invasive surgeries from establishing diagnosis to therapeutic interventional management. The holistic approach provided through interventional radiology reduces intraprocedural time as well as hospital stay. We describe a very rare case of peripheral congenital porto-systemic shunt communicating Inferior mesenteric vein and internal iliac vein with rectal bleed with complete management at the department of interventional radiology.
