Hemorrhagic gastroduodenal artery pseudoaneurysm coil embolization

Area of Science:

• Interventional Radiology
• Vascular Surgery
• Gastroenterology

Background:

• Image-guided percutaneous interventions are increasingly used for pseudoaneurysms when endovascular access is limited.
• These procedures can be technically demanding due to complex anatomy and proximity to vital structures.

Observation:

• A patient with a history of intraductal papillary mucinous neoplasm, status post-Whipple procedure, presented with hemorrhage from a gastroduodenal artery pseudoaneurysm.
• The pseudoaneurysm's location posed significant technical challenges for treatment.

Findings:

• A successful percutaneous treatment of the gastroduodenal artery pseudoaneurysm was achieved.
• An anterior abdominal approach utilizing a blunt-tip needle technique was employed.
• This technique effectively avoided injury to adjacent bowel structures.

Implications:

• This case demonstrates a viable and safe percutaneous strategy for managing challenging pseudoaneurysms in complex abdominal cases.
• The blunt-tip needle technique offers a potential solution to minimize risks associated with visceral proximity.
• This approach may expand treatment options for pseudoaneurysms in patients with prior abdominal surgery.
