Nodular thyroid disease is a very common finding in\ud
clinical practice, discovered by ultrasound (US) in about\ud
50 % of the general population, with higher prevalence in\ud
women and in the elderly [1–4].\ud
Whereas therapeutic flowchart is quite established and\ud
shared for malignant lesions, multiple options are now\ud
available for patients presenting with benign thyroid nod-\ud
ules, ranging from simple clinical and US follow-up to\ud
thyroid surgery. The majority of thyroid nodules, benign by\ud
fine-needle aspiration, are asymptomatic, stable, or slow-\ud
growing over time and require no treatmen
• RAS and ablation margins are predictors of local tumour progression-free survival. • Ablation margin >10 mm, always desirable, is crucial for mutant RAS metastases. • Interventional radiologists should be aware of RAS status to optimize LTPFS.
Interventional radiology is an effective therapeutic alternative for the treatment of most biliary strictures complicating OLT. It has a high success rate and should be considered before surgical interventions. Elective surgery may be necessary in a few failed cases or those with more severe and extensive biliary strictures.
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.
