This study concerns 110 patients who were underwent anatomical snuffbox arteriovenous fistula at Department of Surgery, Holy Family Hospital, College of Medicine, The Catholic University of Korea, from January 1995 to December 1997. We analysed the overall and success patency rate between diabetic and non-diabetic patients. The results obtained are as follows: 1) 52 operations were performed on male patients and 58, on females. And mean age was 51 years. 2) Average follow-up period was 19 months. 3) Early failure rate of all cases was 17 cases (15%), 2 cases (6%) in diabetic patients and 15 cases (9.7%) in non-diabetic patients. 4) Overall patency rates of all patients were 76.6, 72.0, 68.8 and 64.9% at 6, 12, 18 and 24 months and success patency rates were 90.7, 85.2, 81.4 and 76.8% after creation of anatomical snuffbox arteriovenous fistulas. 5) Overall patency rates of diabetic patients were 78.8, 74.8, 74.8 and 59.8% at 6, 12, 18 and 24 months and success patency rate were 83.4, 79.4, 79.4 and 63.5%. 6) Overall patency rate of non-diabetic patients were 75.9, 71.0, 66.6 and 66.6% at 6, 12, 18 and 24 months and success patency rate were 94.5, 88.4, 83.0 and 83.0%.

The ectopic bone formation is a condition in which mature lamellar bone is formed in tissues that do not normally ossify, which was first described by Riedel in 1883. It has been observed at sites of chronic infection, hemorrhage, fibrous scamng or contracture. The pathophysiology of ectopic bone formation is not clearly identified but has complex and multifaceted causes, which resulted to differentiate the non-circulating pluripotent mesenchymal cells to osteoblastic stem cells. The local environment conditions of trauma, disruption of soft tissues and periostium, bone debris, hematoma, damaged muscle, uncommitted fibroblasts are suspected to be one of the causes of this condition. Comparing to simple soft tissue calcification, the ectopic bone has all the morphologic and biochemical characteristics of orthotopic bone, which is subjected to turnover and even has the ability for bone marrow formation. A case of late occlusion in a femoro-post. Tibial PTFE graft about 5 months after vascular reconstruction due to ectotopic bone formation, which is confirmed by pathology around the graft is presented. After excision of the ectopic bone around the inflow vascular anastomosis site with re-vascularization, the patient was free from the ischemic leg symptoms. We reported a case of occlusion of vascular anastomosis site by ectopic bone formation with review of literature.
