Clinical performance
We make decisions on the course of treatment after determining whether a patient definitely needs revascularization (catheterization or surgical treatment). Typically, patients are treated with medications. However, revascularization is considered when symptoms are severe. Many of our patients have severe conditions. As a result, we perform approximately 200 catheterizations each year. Our success rate is higher than 90%, including difficult cases. For patients who cannot be treated with catheterization or for whom catheterization is not suitable, surgical treatment is selected. For this reason, we hold a joint conference every week with the Division of Vascular Surgery and the Department of Radiology to decide on the optimal therapeutic method for each patient.
Selected cases
Selected cases of catheterization for occluded arteries due to arteriosclerosis are shown below
Arteriosclerosis obliterans in the lower extremities
A woman in her 80s with intermittent claudication due to occlusion from the abdominal aorta to both iliac arteries
Stents were placed at the site of occlusion (indicated with arrows) located from the aorta to both common iliac arteries. Blood flow was successfully restored. Intermittent claudication in both feet resolved. The patient returned to her daily routine.
Arteriosclerosis obliterans in a lower extremity
A man in his 70s with intermittent claudication due to right iliac artery occlusion
Right external iliac artery occlusion (indicated with arrows) was treated with stenting. Symptoms were alleviated.
Arteriosclerosis obliterans in a lower extremity
A man in his 60s with intermittent claudication due to right superficial femoral artery occlusion
The occlusion in the right superficial femoral artery occlusion (indicated with arrows) was treated with stenting. Symptoms were alleviated.
Arteriosclerosis obliterans in a lower extremity
A woman in her 70s with foot gangrene due to arterial occlusion in the right lower leg
Blood flow was restored with balloon treatment of an occlusion in the right anterior tibial artery (indicated with arrows). Gangrene was completely cured at 3 months.
Arteriosclerosis obliterans in a lower extremity
A man in his 70s with intermittent claudication due to occlusion from the left iliac artery to the common femoral artery
Hybrid therapy, with advantages of both catheterization and surgery, was used in this patient. The occlusion in the left iliac artery was treated with stenting (indicated with thin arrows). To avoid the use of stents across the hip joint, the occlusion in the left common femoral artery was treated surgically with thromboendarterectomy (indicated with a thick arrow).
