He smiled and thanked Director Gu Yongquan and the medical staff who took care of him, and he was like a family. After the diagnosis of vascular surgery, it was clear that the old man was suffering from main iliac artery occlusive disease, that is, the thickest arterial trunk of the human body – the end of the aorta and its bifurcation into the lower limbs of the iliac artery has serious atherosclerosis, atheromatous calcified plaque The arterial lumen is blocked, resulting in stenosis and occlusion. After careful examination and preparation, the vascular surgery department performed laparoscopic bypass surgery from the abdominal aorta to the femoral artery for Mr. Han on December 8, and the procedure went very smoothly. Mr. Han is the third case of laparoscopic bypass of the main iliac artery completed by the Department of Vascular Surgery in 2011. The previous two cases were also successful, and the patient reaped satisfactory results. Guo Jianming, Department of Vascular Surgery, Xuanwu Hospital, Capital Medical University In recent years, an increasing number of patients with aortoiliac artery occlusion have been coming to the Department of Vascular Surgery. Because of the high location of the lesion, it often involves a wide range of ischemia and heavy degree. Traditional surgical treatment requires opening the abdomen to bypass, and patients are not only traumatized but also face high risks of surgery and complications, which many frail elderly people cannot withstand. In recent years, interventional surgery has been in full swing in the treatment of main iliac occlusion, but always seems to be poor, although interventional trauma is small and recovery is fast, but often the lesion cannot be opened due to severe calcification, in addition, the high cost of interventional surgery also discourages some patients. The application of laparoscopic aortoiliac artery bypass technique has brought light to patients with aortoiliac artery occlusion. This procedure was first performed abroad in 1996 and has been developing rapidly worldwide in the last 5 years. Under the leadership of Director Yongquan Gu, the laparoscopic team of the Department of Vascular Surgery has mastered this difficult surgical operation through unremitting hard work. This procedure allows the aortoiliac artery bypass to be performed only through a few small holes in the abdomen, completely under laparoscopy, effectively solving the problems that could not be overcome by the two previous procedures, which not only gives the patient a definite long-term patency rate, overcomes the disadvantages of traditional surgery with high trauma and many complications, but also has the advantages of fast postoperative recovery, reliable efficacy and low cost, bringing a boon to patients suffering from aortoiliac artery occlusion.
