Perigraft hygroma is a known complication of prosthetic graft implantation. The specific etiology of perigraft hygromas is still unknown. We report 2 brothers who underwent open abdominal aortic aneurysm repairs with polytetrafluoroethylene grafts that developed progressively enlarging perigraft hygromas. This is the first case report of 2 brothers developing sac hygromas after open abdominal aortic aneurysm repair. This case demonstrates that there could be a genetic component associated with the development of perigraft hygromas and further investigation of genetic etiologies should be considered.
