Combined endovascular and surgical treatment of a giant celiac artery aneurysm with consequent gastric outlet obstruction: a case report and literature review

Abstract

Background

Visceral artery aneurysms (VAA) are rare with an incidence of up to 0.2% and mortality of up to 40%. Aneurysms larger than 5 cm are referred to as giant visceral artery aneurysms (GVAA). We present a case of a celiac artery aneurysm of 14 cm which required endovascular and surgical management. A review of the literature with focus on treatment is also provided.

Case presentation

In this case report, a 76-year-old male presented with postprandial nausea and vomitus. An ultrasound and computed tomography scan showed an aneurysm of the celiac artery of approximately 14 cm. Initial treatment was conducted with coiling. Despite this treatment, patient presented again with the same complaints, most likely due to gastric outlet syndrome caused by the aneurysm sac. Partial open removal of the aneurysm sac was performed with release of the duodenum. Due to recurring dysphagia and postprandial nausea, a gastroenterostomy was created, which was later supplemented with a Roux-en-Y anastomosis due to gastroparesis. Patient recovered uneventful after the Roux-en-Y and was discharged from the hospital.

Conclusion

Giant visceral artery aneurysms sometimes need multimodal treatment. We showed that an endovascular first approach of a giant visceral artery aneurysm is not only technically feasible, but it also facilitates subsequent open surgery due to limiting blood loss and reducing the need for extensive mobilisation of the viscera to gain arterial control.
