Official title:
Hemodynamic Study of In-Stent Stenosis After Flow Diverter Implantation for Intracranial Aneurysms Based on 3D-DSA Combined With TCCD
DTFI is a single-center, prospective cohort study aimed at evaluating the hemodynamics of in-stent stenosis after flow diverter implantation, seeking to identify the threshold effect of blood flow in stenosis.
DTFI study investigates the hemodynamic changes in patients with intracranial aneurysms who have undergone flow diverter implantation, using a combination of three-dimensional digital subtraction angiography (3D-DSA) and transcranial color-coded duplex (TCCD) sonography. The aim is to understand the development of in-stent stenosis and its impact on blood flow. ;
