Simultaneous Bilateral Vertebral Artery 3D Rotational Angiography. Technical Report of Two Cases

Area of Science:

• Neurology
• Vascular Surgery
• Radiology

Background:

• Vertebrobasilar junction aneurysms, especially those with fenestrations, present diagnostic challenges.
• Standard angiography may not provide sufficient anatomical detail for these complex cases.

Purpose of the Study:

• To report the first use of simultaneous bilateral vertebral artery rotational angiography.
• To evaluate the effectiveness of this technique in visualizing complex aneurysms.

Main Methods:

• 3D rotational angiography was performed.
• Initial single vertebral injections yielded insufficient detail in two cases.
• Simultaneous bilateral vertebral artery injections and rotational runs were then utilized.

Main Results:

• Simultaneous bilateral injection provided superior anatomical detail compared to single injection.
• Enhanced visualization facilitated appropriate treatment planning.

Conclusions:

• Simultaneous bilateral vertebral artery 3D rotational angiography is a valuable tool for complex vertebrobasilar junction aneurysms.
• This technique offers improved anatomical insight for endovascular intervention planning in rare fenestrated aneurysm cases.
