Abstract

Endovascular aneurysm repair (EVAR) using stent grafts has shown to be an effective alternative to surgical repair in treating an abdominal aortic aneurysm (AAA). EVAR is associated with shorter hospital stays, less blood loss, shorter operating times, and lower early morbidity and mortality compared to open surgical repair, although EVAR required a higher reintervention rate during a longer follow-up period. However, short or severely an angulated infrarenal proximal aortic neck is considered unsuitable for EVAR. The chimney graft technique is a modified procedure based on the deployment of a covered or bare-metal stent parallel to the main aortic endograft within the aneurysm, thereby creating a conduit that runs outside the aortic main endograft to preserve flow to the aortic branches. In this case report, we present a 78-year-old patient with an AAA with a short and severely angulated proximal neck who was successfully treated by EVAR using the chimney graft technique.
