Summary
False aneurysms, a complication of chronic pancreatitis, can cause severe bleeding. Embolization attempts in three patients led to gastrointestinal rupture, highlighting procedural risks.
Area of Science:
- Gastroenterology
- Vascular Surgery
- Interventional Radiology
Background:
- False aneurysms of pancreatic and peripancreatic arteries are known complications of chronic pancreatitis.
- These aneurysms result from arterial wall degradation by proteolytic enzymes.
- They pose a significant risk of life-threatening hemorrhage.
Observation:
- Three cases of attempted embolization for bleeding false aneurysms are presented.
- In all three cases, the embolization procedure resulted in aneurysm rupture into the gastrointestinal tract.
Findings:
- Attempted embolization of bleeding pancreatic artery false aneurysms can lead to catastrophic rupture into the gastrointestinal tract.
- The inherent weakness of the aneurysmal wall contributes to this complication.
Implications:
- Special precautions are crucial during embolization procedures for pancreatic artery false aneurysms.
- These findings underscore the need for careful patient selection and technique optimization in interventional management.
- Further research into safer treatment modalities for these complex vascular lesions is warranted.
