Common bile duct compression by an abdominal aortic aneurysm
Endoscopy
|March 1, 1986
Summary
A calcified abdominal aortic aneurysm caused extrinsic compression of the common bile duct, leading to stenosis. This rare finding was diagnosed in a patient presenting with oral bleeding and disseminated intravascular coagulation.
Area of Science:
- Gastroenterology
- Vascular Surgery
Background:
- Disseminated intravascular coagulation (DIC) is a serious condition with varied etiologies.
- Biliopancreatic tumors are a differential diagnosis for common bile duct obstruction.
Observation:
- A 76-year-old female presented with oral bleeding and laboratory findings indicative of DIC.
- Endoscopic cholangiography revealed symmetrical stenosis in the lower common bile duct.
Findings:
- The common bile duct stenosis was caused by extrinsic compression from a calcified abdominal aortic aneurysm.
- CT scan confirmed the anatomical relationship between the aortic aneurysm and the common bile duct.
Implications:
- This case highlights a rare cause of common bile duct obstruction.
- Awareness of vascular compression is crucial in diagnosing biliary pathologies.
