AneurysmFlow
Cerebral aneurysm flow quantification
Assessing impact of embolization devices, like flow diverters, on blood flow right after deployment is crucial. AneurysmFlow is designed to provide relevant information based on quantification of blood flow changes.

Expanding functional understanding
Currently, a combination of digital subtraction angiography (DSA) and three-dimensional rotational angiography (3DRA) is the gold standard for imaging vascular lesions, but it provides limited functional information about flow. AneurysmFlow uses novel algorithms based on the optical flow principle to convert information from a 3DRA acquisition and 2D DSA flow sequences into quantitative flow values. These values are used to visualize and quantify flow dynamics before and after flow diverter deployment in cerebral aneurysms.
Step-by-step workflow
AneurysmFlow supports endovascular treatment of saccular cerebral aneurysms with embolization devices, such as flow diverters. Data acquisition can be controlled at the tableside during the normal workflow, while analysis is performed in the control room.
Relevant information about blood vessel flow
Flow diverters are being increasingly used to treat cerebral aneurysms, but flow diversion procedures remain challenging. Only 76% of all aneurysm flow diversion cases result in thrombosis after 6 month follow-up,¹ which poses a risk to the patient. Several authors have shown that the flow pattern inside aneurysms is considered one of the parameters that can be used to predict rupture and clotting.²,³
AneurysmFlow is the first tool that visualizes and quantifies flow changes in the parent vessel and aneurysm before and after flow diverter deployment. It also provides a unique metric – the Mean Aneurysm Flow Amplitude (MAFA) ratio.
