[Pseudoaneurysm in a pancreatic pseudocyst]

Area of Science:

• Gastroenterology
• Vascular Surgery
• Diagnostic Imaging

Background:

• Pancreatic pseudocysts are a known complication of pancreatitis.
• Pseudoaneurysms can develop secondary to pancreatic pseudocysts, posing a significant risk of hemorrhage.
• Effective diagnostic and therapeutic strategies are essential for managing this condition.

Observation:

• The study reports four cases of pseudoaneurysm formation originating from pancreatic pseudocysts.
• Diagnostic signs, both specific and non-specific, for pancreatic pseudoaneurysm on duplex scan are detailed.
• Literature data on diagnostic and therapeutic options and their success rates were analyzed.

Findings:

• All reported patients with pseudoaneurysms secondary to pancreatic pseudocysts were successfully treated surgically.
• Selective feeding artery ligature is highlighted as a beneficial therapeutic approach.
• Ultrasound follow-up is emphasized for early detection and prevention of complications.

Implications:

• Early and accurate diagnosis of pancreatic pseudoaneurysms via ultrasound is vital.
• Surgical management, particularly selective feeding artery ligature, offers successful treatment outcomes.
• Regular ultrasound monitoring in pancreatitis patients can prevent life-threatening hemorrhage from pseudoaneurysms.
