These results suggest that there is a theoretical advantage of oversizing an aortic prosthesis and that sufficient anchorage is achieved in an aortic neck of 10 mm to prevent migration when fully deployed.
carotid endarterectomy can be performed safely under local anaesthesia with the advantage that LA CEA enables the surgeon to monitor and selectively shunt patients more accurately. In addition LA CEA is associated with a shorter hospital stay and important cost savings.
An evaluation was made of the histological material obtained from all 1529 appendices removed during the last 5 years at Southmead Hospital, Bristol, in order to elucidate possible relationships between the incidence of Enterobius vermicularis and the origin of inflammation in the appendix. In total, 1419 appendices were removed as cases of clinical appendicitis and 110 in the course of another surgical procedure. E. vermicularis was identified in 2.7 per cent of patients with clinical appendicitis and was most commonly seen in appendices with either chronic inflammation or where the appendix was histologically normal. E. vermicularis was rarely associated with histological changes of acute appendicitis. No cases of E. vermicularis infestation occurred in appendices removed during the course of other surgical procedures. The results suggest that, although E. vermicularis may have a causal role in appendicular pain and chronic inflammation, it is rarely related to acute appendicitis.
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.
