Patient	Angiography	Interventional therapy
1	Occlusion right internal iliac artery, high grade stenosis left internal iliac artery	NA
2	Occlusion of both internal iliac arteries, aneurysm of the abdominal aorta	NA
3	High grade stenoses of the left common and internal iliac artery	PTA in two sessions with good clinical results
4	Occlusion of the right internal iliac artery, high grade stenosis right internal iliac artery; C/A aortobifemoral Y-bypass surgery	Multiple surgical reconstructions of the bypass without significant clinical improvement
5	High grade stenosis of the distal abdominal aorta and both proximal common iliac arteries (right more than left)	Stent implantation distal abdominal aorta and the right common iliac artery combined with PTA of the left common iliac artery with good clinical results
