Summary
This study evaluated AneurysmFlow software for assessing flow changes after flow-diverting treatment in aneurysms. Quantitative flow changes did not correlate with aneurysm occlusion status at 6 months.
Area of Science:
- Medical Imaging
- Interventional Radiology
- Biomedical Engineering
Background:
- AneurysmFlow, a novel optical flow-based tool from DSA, requires further validation.
- Flow-diverting stent (FDS) treatment is a key intervention for aneurysms.
Purpose of the Study:
- To assess the significance of flow velocity changes and Mean Aneurysm Flow Amplitude (MAFA) ratio in predicting outcomes after FDS treatment.
- To evaluate the utility of AneurysmFlow software in post-treatment aneurysm assessment.
Main Methods:
- Retrospective analysis of 41 patients (42 aneurysms) treated with FDS and measured using AneurysmFlow.
- Analysis of flow velocity changes and MAFA ratio in relation to aneurysm characteristics and occlusion status at 6-month follow-up.
Main Results:
- AneurysmFlow achieved a 90.5% success rate in 38 aneurysms.
- A decrease in flow velocity was observed in 78.9% of cases post-stent deployment.
- No significant association was found between flow changes, MAFA ratio, and aneurysm size or occlusion status at 6 months.
Conclusions:
- Quantitative flow changes measured by AneurysmFlow software did not correlate with aneurysm occlusion status at 6 months post-FDS treatment.
- Larger studies with longer follow-up are needed to further investigate these findings and the role of AneurysmFlow.

01:29Blood Flow
57.4K
Blood is pumped by the heart into the aorta, the largest artery in the body, and then into increasingly smaller arteries, arterioles, and capillaries. The velocity of blood flow decreases with increased cross-sectional blood vessel area. As blood returns to the heart through venules and veins, its velocity increases. The movement of blood is encouraged by smooth muscle in the vessel walls, the movement of skeletal muscle surrounding the vessels, and one-way valves that prevent backflow.

01:27Steady Flow of a Fluid Stream
972
Consider a control volume, such as a pipe with solid boundaries, through which fluid flows and changes direction due to the impulse exerted by the resulting force from the pipe walls. In steady flow, the mass of fluid entering the control volume at a given time, t, with velocity v1, is equal to the mass leaving after infinitesimal time dt, with velocity v2.
During this process, the momentum of the fluid within the control volume remains constant over the time interval dt. By applying the...

1.5K
In pipe flow measurement, orifice, nozzle, and Venturi meters are commonly used to determine fluid flowrates by constricting the flow area, which increases fluid velocity and reduces pressure. This pressure difference, governed by Bernoulli's principle and adjusted for real-world conditions, is essential for calculating flowrate. Each meter type is suited to specific applications based on accuracy, efficiency, and compatibility with various flow conditions.

01:26General External Flow Characteristics

The study of external flow is essential for creating structures and objects that interact efficiently and safely with moving fluids, such as air or water. When a body is immersed in a flowing fluid, it experiences two primary forces: drag, which opposes motion along the flow direction, and lift, which acts perpendicular to the flow. The shape, size, and orientation of the object influence these forces.Streamlined and Blunt Bodies in External FlowObjects in fluid flow are classified as...

01:24Rapidly Varying Flow
731
Rapidly varying flow (RVF) in open channels is characterized by abrupt changes in flow depth over a short distance, with the rate of depth change relative to distance often approaching unity. These flows are inherently complex due to their transient and multi-dimensional nature, making exact analysis difficult. However, approximate solutions using simplified models provide valuable insights into their behavior.Key Features of Rapidly Varying FlowRVF is commonly observed in scenarios involving...

01:27Applications of Integration to Find Blood Flow

Blood flow through a cylindrical blood vessel can be mathematically described using the principles of laminar flow, a regime in which fluid moves smoothly in parallel layers. In this model, the velocity of the blood is not uniform across the cross-section of the vessel; rather, it varies with the radial distance from the center. The maximum velocity occurs along the central axis, decreasing progressively toward the vessel walls, where it reaches zero due to viscous drag.Approximating Blood...
