Extra information provided by this project
Original uncertainty examples What is the natural history, including gene mutation, of intracranial aneurysm in people with ADPKD? ~ Development of a decision strategy addressing cost, safety and efficacy of magnetic resonance angiography (MRA) screening, for intracranial aneurysm in people with ADPKD, and for therapeutic approaches. ~ Which anti-hypertensive therapy is most effective for the prevention of intracranial aneurysm (ICA) in people with ADPKD? ~ Is systematic screening for intracranial aneurysm effective and efficient, in people with ADPKD, undergoing pre-transplant evaluation or major surgery? ~ Which therapeutic interventions including endovascular coiling are most effective for intracranial aneurysm in people with ADPKD, and how do the morbidity and mortality rates compare in the ADPKD and non-ADPKD population? ~ In children and young people with ADPKD what is the incidence of sub-arachnoid haemorrhage and the prevalence of intracranial aneurysm? ~ In adults, children and young people with ADPKD with a family history of intracranial aneurysm or sub-arachnoid haemorrhage does Intracranial Magnetic Resonance (MR) imaging reduce the risk of intracranial events?
