These preliminary observations suggest that elective, nonsurgical insertion of an endovascular stent-graft is safe and efficacious in selected patients who have thoracic aortic dissection and for whom surgery is indicated. Endoluminal repair may be useful for interventional reconstruction of thoracic aortic dissection.
The successful resection of an abdominal aortic aneurysm is presented in a patient who had undergone kidney transplantation 4 years previously. Because the transplanted kidney is more sensitive to ischemia than a normal one, a femoro-femoral bypass with a pump oxygenator was used for perfusion of the transplanted kidney during crossclamping. During the clamping time of 40 minutes kidney perfusion was maintained with a perfusion pressure of 60 to 80 mmHg and the flow was 600 to 1000 ml/min. A collagen-seeded Dacron graft (diameter: 18 mm, length: 12 mm) was interposed. The postoperative course was uncomplicated. We believe that performing the femoro-femoral bypass with a pump oxygenator is an effective and simple method for kidney protection in such operations.
As an adjunctive imaging modality IVUS is likely to improve stent-graft placement in aortic type B dissection, especially in patients with abdominal extension.
ENTAL DECAY is considered by some to exert a detrimental effect on L} occlusion; however, there is no complete agreement in the literature establishing the amount of dental malocclusion stemming from the early loss of tooth material. Plater' reported the range to be from 18 to 35 per cent, depending on who made the classification. Where there is a pronounced reduction in the incidence of dental caries among school children it is, therefore, logical to assume there might also be a reduction in the prevalence of malocclusion.The Evanston children have shown a remarkable lowering of dental caries rates since the Evanston water was fluoridated.2 The rates of the control, fluoride-free area, children have remained practically unchanged over a 9-year period.2 The two groups with dissimilar caries rates provided a reliable basis for comparing the incidence of malocclusion among children with high caries rates with those having low caries rates.The dental records provide excellent information concerning the premature loss of the second deciduous molar teeth with respect to occlusion. Many of the same Evanston children examined at 6, 7, and 8 years of age were examined again at 12, 13, and 14 years of age. This made possible the opportunity to observe the occlusion of these children during a growth period.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
