Atherosclerotic occlusive disease (ASO) caused by peripheral vascular atherosclerosis is a high incidence, and with the change of diet structure, the incidence of ASO in China is on the rise. Atherosclerosis occlusive disease to most occur in the lower extremities, the main manifestation is the lower extremity ischemic symptoms, mostly chronic ischemia of the limbs, symptoms progressive, from mild to severe, such as early limb chills with cold limbs, numbness does not pay attention to the typical symptoms intermittent claudication, late onset of resting pain, primary ulcers or gangrene, etc. On December 6, Fan, 46 years old, from the Department of Vascular Surgery, was hospitalized with intermittent claudication of both lower extremities for 2 years. Ultrasound and CTA examination showed that the right iliac artery was occluded for about 200 px and the left iliac artery was nearly occluded. The preoperative discussion and consultation within the department showed that it would be more costly and traumatic to place “abdominal aorta-type split-leg stent”, but the patient’s lesion scope was not a long segment occlusion, so it was feasible to treat the patient with the more advanced international “pair of kissing stents” technique, which is inexpensive and has a long-term postoperative The patency rate is comparable to that of the “abdominal aorta-type split-leg stent”. On December 10, after proper preoperative preparation, Dr. Wang Bing, the chief surgeon, successfully completed the “iliac artery buttress stent implantation” in our “hybrid operating room”. At the post-operative follow-up, the patient’s intermittent claudication symptoms completely disappeared and the arterial pulsation of the lower limbs resumed. It is understood that the vascular surgery department of our hospital has been performing interventional surgery for many difficult cases of iliac artery occlusion since 2006, and all of them have achieved better treatment results. The present case of stent implantation with anastomosis made a new breakthrough in the surgical treatment of ASO-iliac artery occlusion in vascular surgery.
