RESUMO
Clinical management of renal artery stenosis has seen a major shift, after randomised clinical trials have shown no group benefit of endovascular intervention relative to optimal medical control. However, the inclusion criteria of these trials have been criticised for focusing on a subset of patients with atherosclerotic renal artery stenosis where intervention was unlikely to be beneficial. Moreover, new imaging and computational techniques have become available, which have the potential to improve identification of patients that will respond to interventional treatment. This review addresses the challenges associated with clinical decision making in patients with renal artery stenosis. Opportunities for novel diagnostic techniques to improve patient selection are discussed, along with ongoing Dutch studies and network initiatives that investigate these strategies.

BACKGROUND: The use of 4-fluoroamphetamine (4-FA) has shown a marked increase, especially because users perceive its effects to be relatively mild. 4-FA is also known as ecstacy-light, but is probably not as light as its name suggests. From April 2017 its use has therefore been forbidden in the Netherlands. CASE DESCRIPTION: In a short time, we saw three patients at our emergency department who had signs of a severe intoxication with 4-FA. A 21-year-old male developed a tonic-clonic seizure, bruxism, mydriasis, and rhabdomyolysis. A 19-year-old female was confused and was longing for death. A 22-year-old male needed to be admitted to intensive care to be intubated, sedated and cooled due to tachycardia, hypertension and hyperthermia. CONCLUSION: Because of its relatively mild effects, 4-FA is gaining in popularity in the Netherlands. However, the use of this designer drug can lead to severe problems such as severe confusion, hyperthermia and tonic-clonic seizures.
