Iliac Angioplasties: Impact of the Fusion of Images on the Irradiation Rate (AIFITI)

April 28, 2022 updated by: Ramsay Générale de Santé

Atherosclerosis can cause the arteries to narrow (stenosis) or clog (occlude), leading to reduced blood flow.

Arteriography or angiography is a radiological examination of the arteries which will make it possible to confirm and quantify the severity of the damage to the artery and which, in certain cases, can be directly treated by angioplasty with or without stenting (selective angioplasty).

Digital subtraction angiography (DSA), the reference technique, provides good image quality. The fluoroscopy used today during angioplasty procedures makes it possible to obtain images in real time and to guide the progression of the endovascular material in the arterial axis. Image fusion is an established technique for the endovascular treatment of aortic aneurysms. The feasibility of image fusion for the iliac arterial axes has already been assessed and is reproducible. However, there is no assessment of the irradiation rate in iliac angioplasty, using intraoperative image fusion, compared to standard angioplasty practices.

Study Overview

Detailed Description

Atherosclerosis can cause the arteries to narrow (stenosis) or clog (occlude), leading to reduced blood flow. Iliac stenosis can be asymptomatic or symptomatic. Clinical manifestations are related to the degree of narrowing. The symptoms are in order of increasing severity: pain in the legs when walking (intermittent claudication), at rest, even foot or leg ulcers.

Arteriography or angiography is a radiological examination of the arteries requiring the injection of contrast product which will make it possible to confirm and quantify the severity of the damage to the artery and which, in certain cases, can be directly treated by angioplasty with or without stenting (selective angioplasty).

  • Interventional Model: Parallel Assignment
  • Masking: Single

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Active Comparator: Angioplasty DSA
Reference procedure (DSA), comprising: production of fluoroscopy images for placement of endoluminal material and navigation, subtracted angiography with placement of flaps to reduce the field of rays ("collimation ") for visualization of the arterial axis (in low dose, pulsed with maximum collimation), the realization of possible oblique incidences (external iliac), the catheterization with or without placement of a post-inflation stent, then the realization of a second subtracted control angiogram.
Angioplasty Iliac done following standard practice
Experimental: Angioplasty DSA+Fusion
Procedure under study (DSA+Fusion), including: production of fluoroscopy images for placement of the endoluminal material and navigation, 2 fluoroscopy images specifically for image fusion registration (from the images scanner), selective angiography under fluoroscopy with collimation to improve registration (in low dose mode, pulsed with maximum collimation), if possible no oblique views (3D markers of the fusion), with or without placement of post-inflation stent followed by subtracted control angiography
Angioplasty Iliac under additional 3D Images merged as surgery support

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Irradiation rate
Time Frame: "immedialtely at the end of surgery procedure"
mean irradiation rate during iliac angioplasty will be compared between the 2 study groups The primary endpoint of the research is the patient's intraoperative irradiation rate defined by measuring the dose area product (DAP) in Gy.cm2
"immedialtely at the end of surgery procedure"
