Cost-effectiveness of CTA, MRA and IA-DSA in patients with ruptured intracranial aneurysms: A decision model

Ziele: In patients with non-traumatic subarachnoid hemorrhage, intra-arterial digital subtraction angiography (IA-DSA) is the golden standard for the detection of ruptured intracranial aneurysms and determination of their feasibility of endovascular coiling. Contrast enhanced magnetic resonance angiography (MRA) and computed tomography angiography (CTA) are two non-invasive alternatives to current standard. With imaging deeming no feasibility of endovascular treatment, surgical clipping is an alternative treatment option with slightly higher costs and minor outcome over a one year period. The goal of this study…
