Stent-graft infection may be a cause of unexplained endotension. Special culture techniques may be required to identify the infecting organism. Prophylactic antibiotics against skin organisms should be considered for all implantations and arterial diagnostic and therapeutic procedures traversing a stent-graft.
The administration of high-dose oxygen to vascular surgical patients undergoing lower-limb arterial surgery results in increased tissue oxygen concentrations when perfusion is not reduced by the presence of arterial clamps. These results suggest the administration of high-dose oxygen intraoperatively may be beneficial in reducing wound infections, but further research is required.
A 58-year-old woman presented with bilateral upper limb ischaemia. Digital subtraction angiography demonstrated upper limb arterial thrombosis, extensive on the left. This was initially treated with catheter-directed thrombolysis which cleared the thrombus on the right, although the left upper limb required supplementary surgical embolectomy. Subsequently, biopsy-proven pancreatic adenocarcinoma was detected. The upper limb arterial thrombosis appeared to be spontaneous in association with the malignancy because there was no obvious embolic source.
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.
