Abstract:
Objective To study the cognition and treatment of outflow tract stenosis in and after endovascular exclusion for abdominal aortic aneurysm. Methods From Mar 1997 to Oct 2002, in 136 patients undergoing abdominal aortic aneurysm endovascular exclusion, 8 patients had outflow tract stenosis during the operation, and 3 patients had outflow tract stenosis after operation. The stenosis of 5 patients occurred at the crotch of the graft stent. PTA was done in 7 patients with stents placed in stenotic segment in 2 patients. 2 patients were treated with crossover operation. Results Following up 1 month to 2 years, all patients have no lower limbs ischemia. Conclusions The diagnosis of outflow tract stenosis during and after abdominal endovascular exclusion for aortic aneurysm must be in time. The treatment should be according to the different causes of stenosis.
