# Two-Stage Hybrid Treatment of Residual Inferior Pancreaticoduodenal Artery Aneurysm Following Treatment of Ruptured Superior Pancreaticoduodenal Artery Aneurysm: A Case Report

## TL;DR

A 72-year-old man had a residual artery aneurysm after treatment of a ruptured aneurysm, requiring a two-stage surgical approach.

## Contribution

This case report introduces a two-stage hybrid treatment strategy for residual pancreaticoduodenal artery aneurysms.

## Key findings

- A two-stage surgical approach was used to manage a residual inferior pancreaticoduodenal artery aneurysm.
- Careful vascular reconstruction was necessary to avoid organ ischemia and pressure fluctuations.
- Prior embolization and patient condition influenced the surgical strategy.

## Abstract

Herein, we describe the case of a 72-year-old man who presented with a residual inferior pancreaticoduodenal artery aneurysm following the rupture and treatment of a superior pancreaticoduodenal artery aneurysm. Open surgery for pancreaticoduodenal artery aneurysms requires carefully planned vascular reconstruction to prevent organ ischemia and minimize pressure changes caused by fluctuations in mechanical stress. Additionally, in cases of rupture, factors such as the patient’s condition, presence of hematoma and adhesions, and pressure changes resulting from prior transarterial embolization must be considered. This case report outlines the surgical strategy employed for managing the residual inferior pancreaticoduodenal artery aneurysm.
