Chimney endovascular aortic repair is a viable salvage technique in a paravisceral pseudoaneurysm secondary to acute on chronic pancreatitis

Abstract

Background Pseudoaneurysms of the abdominal aorta secondary to pancreatitis are an extremely rare clinical entity, however, can result in life threatening complications. Objective To describe a chimney endovascular aneurysm repair (Ch-EVAR) for an acute pancreatitis related paravisceral aortic pseudoaneurym. Method Prospective data collected from subject. Results We present a case of 23-year-old female who underwent a successful salvage Ch-EVAR for a ruptured paravisceral pseudoaneurysm secondary to acute on chronic pancreatitis. Conclusion Ch-EVAR may present a viable temporizing or definitive therapeutic treatment option for a paravisceral pseudoaneurysm, particularly in the setting of acute pancreatitis. Further studies are warranted to elucidate the long term viability of Ch-EVAR grafts in the suprarenal, paravisceral aortic position.
