Total laparoscopic repair for abdominal aortic aneurysm

Abstract

Surgical resection and grafting have long been the standard treatment for abdominal aortic aneurysm and provide an excellent long-term outcome. However, there is tremendous impact on patients due to the surgical invasiveness. Endovascular aortic repair using stent graft was introduced in 1991. After refinement of the techniques and technology, endovascular aortic repair was approved by most health authorities and is associated with less periprocedural morbidities. In between these two extremes, some surgeons endeavored to create an alternative and perform less invasive surgeries. Hand-assisted laparoscopic aortic surgery and laparoscopic-assisted aortic surgery were introduced in 1996. In 2001, total laparoscopic abdominal aortic aneurysm resection with tube graft interposition was first performed in Canada. Till now, only a few vascular units in North America and Europe perform these delicate techniques. We report our first case of total laparoscopic abdominal aortic aneurysm repair. Laparoscopic aortic surgery provides better visualization of the aneurysm neck, less bowel manipulation and avoidance of hypothermia. The minimal invasiveness could translate to better perioperative outcome. To our knowledge, this is also the first case report in Asia. The detailed techniques are described.
