Summary
Right hepatic artery syndrome (RHAS) occurs when an artery compresses the bile duct, causing obstruction. This case highlights RHAS diagnosis and successful endoscopic decompression and cholecystectomy in a young male patient.
Area of Science:
- Hepatobiliary surgery
- Vascular anatomy
- Gastroenterology
Background:
- Anatomical variations in the biliary region can lead to complications.
- Extrahepatic bile duct compression by hepatobiliary arteries is a rare but significant cause of biliary obstruction.
- Right hepatic artery syndrome (RHAS) specifically involves compression by the right hepatic artery.
Observation:
- A 22-year-old male presented with abdominal pain, acute calculous cholecystitis, and obstructive jaundice.
- Initial ultrasound suggested Mirizzi syndrome.
- Magnetic resonance cholangiopancreatography revealed Right hepatic artery syndrome (RHAS).
Findings:
- Endoscopic retrograde cholangiopancreatography successfully decompressed the biliary system.
- The patient subsequently underwent a successful cholecystectomy.
- RHAS diagnosis was confirmed, necessitating intervention.
Implications:
- RHAS diagnosis requires advanced imaging like MRCP.
- Management options include endoscopic decompression, cholecystectomy, or hepaticojejunostomy.
- Prompt diagnosis and intervention are crucial for managing biliary obstruction due to RHAS.
