Aim of the study is the description of the successful management of gastroepiploic artery pseudoaneurysm with preservation of parent vessels using flow-diversion technology. The present report describes the application of a flow-diversion Pipeline™ Flex device for occlusion of a sidewall bleeding pseudoaneurysm on a patient who was status-post sub-total pancreatectomy and remote esophagectomy with a gastric conduit. The pseudoaneurysm was on the solitary vessel supplying the patient’s conduit. Use of flow diversion technology excluded the sidewall pseudoaneurysm while maintaining gastric conduit perfusion. In our case, the application of flow diversion technology allowed the preservation of patency of the main arterial supply to the gastric conduit on a post-esophagectomy patient; loss of the right gastroepiploic artery in that case would had been otherwise catastrophic. Flow-diversion technology can be considered for the treatment of pseudoaneurysms post-pancreatic resections, especially when there is no other surgical or endovascular treatment option.
