Colour-coded sonography with a high-frequency transducer head probably provides reliable diagnosis of TA in patients with RP, even in the absence of clinical signs of vascular inflammation. It remains to be proven whether sonography without biopsy is reliable enough for the diagnosis and treatment of asymptomatic TA.
An interaction of the serotonin re-uptake inhibitor with ergotamine was presumably responsible for the development of ergotism under >>therapeutic<< ergotamine dosage. Vasospastic stenoses and occlusions can be demonstrated by duplex sonography and may in future not require additional angiographic confirmation. Intravenous rather than intraarterial infusion of prostaglandin is to be preferred if vessels at many sites are affected. Livedo is a transitory sign of ergotism.
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.
