Intracranial aneurysms may be treated by flow diverters, alternatively to stents and coils combination. Numerical simulation allows the assessment of the complex nature of aneurismal flow. Endovascular devices present a rather dense and fine strut network, increasing the complexity of the meshing. We propose an alternative strategy, which is based ...

Optimal treatment of intracranial aneurysms involves complete occlusion of the aneurysm with preservation of the parent artery and all of its branches. Attempts to occlude the aneurysm and preserve the parent artery may be associated with a higher level of risk than parent vessel occlusion or trapping. To evaluate our ...

Visceral artery aneurysms (VAA) are relatively rare disease patterns. With regard to the aetiology two different entities of VAA can be distinguished: (i)  real VAA, where arteriosclerosis plays an important role, particular in elderly patients, and (ii)  pseudo-aneurysms. Here, previous abdominal trauma or former inflammatory processes are considered to be ...

Flow diverter (FD) devices have emerged as an alternative treatment for a subgroup of intracranial aneurysms. The principle of endovascular flow diversion is inherently different from endosaccular coil embolisation. To monitor the angiographic outcomes for FDs, a sensitive and reliable new measure is required. Oxford Neurovascular and Neuroradiology Research Unit ...
