Radiofrequency ablation of liver tumors is a well-tolerated technique, but caution should be exercised when treating patients with a bilioenteric anastomosis, and radiofrequency ablation during vascular occlusion in cirrhotic livers should be avoided.
Radiofrequency ablation appears to be a promising therapeutic modality capable of extending the possibilities of partial hepatectomy and of efficiently treating small metastases percutaneously.
BACKGROUND AND PURPOSE:Lack of cerebral circulation is an important confirmatory test for brain death (BD). Conventional angiography remains the standard imaging method, but CT angiography (CTA) is emerging as an alternative. France accepts BD diagnoses relying on a score based on lack of opacification of 7 intracerebral vessels in CTA images. The purpose of this study was to validate the efficiency of this score and to evaluate the sensitivity of a novel 4-point CTA score in confirming BD.
Despite the small number of patients, CT and MR imaging may depicted all local regrowth at 4 months or sooner. MR imaging may have an edge over CT in the early detection of local regrowth.
Fluoroscopically guided gastrostomy is highly feasible and safe and provides adequate feeding support, even when percutaneous endoscopic gastrostomy is impossible. Long-term complications, which are mainly tube disturbances, are easily treated.
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.
