Comprehensive data visualization for high resolution endovascular carotid arterial wall imaging.

Area of Science:

• Biomedical Engineering
• Cardiovascular Imaging
• Endovascular Surgery

Background:

• Carotid angioplasty and stenting requires precise monitoring.
• In vivo high-resolution imaging is crucial for assessing stent placement and complications.

Purpose of the Study:

• To evaluate optical coherence tomography (OCT) for high-resolution 2D and 3D imaging of carotid artery stenting.
• To assess OCT's ability to visualize stent placement and complications in a porcine model.

Main Methods:

• A pilot study using four Yorkshire pigs.
• Utilized a state-of-the-art optical coherence tomography (OCT) system and automated injector.
• Acquired and processed 2D and 3D images of healthy and stented porcine carotid arteries.

Main Results:

• OCT successfully captured high-resolution images of carotid arteries.
• High-quality 3D images clearly depicted vessel wall morphology.
• OCT visualized stent apposition and thrombus formation over the stent.

Conclusions:

• Optical coherence tomography (OCT) is effective for generating high-quality 3D images of carotid arterial stents.
• OCT enables accurate diagnosis of stent apposition and complications.
• This imaging technique shows promise for guiding endovascular procedures.
