A non-anastomotic false aneurysm occurred in a 77-year-old male 11 years after bypass grafting between the left external iliac artery and the right femoral artery using a Cooley double velour knitted Dacron graft. The false aneurysm was caused by rupture of an artificial graft. A partial resection of the graft and its replacement using a Hemashield® graft were successfully performed. It was speculated that the mechanical stress by the inguinal band degenerated graft fibers and developed aneurysmal formation.

BACKGROUND: Free fat graft has been used for the treatment of congenital hand differences. However, there have been a few reports about the outcome of that treatment. In this study, the outcome of free fat grafts for congenital hand and foot differences was investigated. METHODS: Fourteen bones with longitudinal epiphyseal bracket, 3 wrists with Madelung deformity, and 5 cases of osseous syndactyly were treated with free fat graft with osteotomy, physiolysis, or separation of osseous syndactyly. Of the fourteen bones with longitudinal epiphyseal bracket, 9 were treated with open wedge osteotomy with free fat graft and 5 with physiolysis and free fat graft. The Madelung deformity was treated with physiolysis with free fat graft. For osseous syndactyly, syndactyly release with free fat graft was performed five times on four hands. RESULTS: In the fourteen cases with longitudinal epiphyseal bracket, lateral deviation improved in all except two cases after surgery. The average lateral deviation angle changed from 32.5 degrees before surgery to 15.2 degrees after surgery. The average improvement of the lateral deviation angle was 12.2 degrees in the osteotomy group and 20.6 degrees in the physiolysis group. The mean ratio of improvement of the lateral deviation angle to the lateral deviation angle before surgery was 39.4% in the osteotomy group and 51.2% in the physiolysis group. The Madelung deformity improved after surgery in two cases but there was no improvement in one case. For these conditions, the results were not good enough when surgery was done after age 13 or at age four for severely hypoplastic brachymesophalangy. Of the 5 cases of osseous syndactyly, reunion of the separated bones occurred in one case. The grafted free fat should be deep enough to cover the osteotomy site of the bones to prevent reunion of the separated bones. CONCLUSIONS: Physiolysis and free fat graft performed during the growth period can correct the deviation due to longitudinal epiphyseal bracket and Madelung deformity. Free fat graft is also useful to prevent reunion of the bones after separation of osseous syndcatyly, if the grafted fat is securely filled into the space between the separated bones.

Objective: Causes and risk factors of neurodevelopmental disorders originate in the prenatal and perinatal periods. Several studies have demonstrated a relationship between prenatal and perinatal medical records, including maternal and paternal age at pregnancy, and the neurodevelopmental disorders, especially attention deficit/hyperactivity disorder and autism spectrum disorder. However, previous studies showed an association between specific learning disorders and environmental toxins such as lead and tobacco smoke, but not parental age.Patients and Methods: This study included 993 university freshmen, and their prenatal and perinatal medical data was collected from maternal and child handbooks. A mental health assessment questionnaire consisting of 24 items covering symptoms associated with neurodevelopmental disorders was administered, corresponding to aspects of attention deficit/hyperactivity disorder, autism spectrum disorder, and learning disorders. The relationship between prenatal and perinatal medical data and questionnaire results was statistically analyzed.Results: The number of available records was 881 (88.7%). Using Spearman’s rank correlation coefficient analysis and trend analysis, a weak but statistically significant relationship was confirmed between paternal age at pregnancy and the score for learning disorder difficulties.Conclusion: Error accumulation in meiosis during spermatogenesis may be one of the risk factors of learning disorders.
