title: Technique of aortic replacement through endovascular stenting before aortic wall resection for primary leiomyosarcoma of the abdominal aorta.
abstract: Tumors involving the aorta represent a challenging situation because the surgical approach can lead to blood loss and/or clamping-related complications such as ischemia, thrombosis, or reperfusion syndromes. We describe the technique of aortic endograft placement to cover part of the abdominal aorta and provide conditions for extensive aortic wall resection, without clamping or blood loss, followed immediately by aortic reconstruction with bovine pericardium. This technique also allows the surgeon to wait for the results of freeze biopsy without additional clamping time, thus avoiding the risk of leaving residual tumor cells in the aortic wall.
