Subarachnoid hemorrhage from intracranial dissecting aneurysm

Area of Science:

• Neurology
• Neurosurgery
• Vascular Neurology

Background:

• Intracranial dissecting aneurysms are rare and potentially fatal vascular lesions.
• The vertebrobasilar circulation is a common location for these aneurysms.

Observation:

• This study reviewed 14 cases of dissecting aneurysms within the vertebrobasilar system.
• Angiographic features of these aneurysms were analyzed.

Findings:

• Dissecting aneurysms in the vertebrobasilar circulation exhibit characteristic angiographic appearances.
• Proximal arterial occlusion demonstrated effectiveness in treating vertebral artery dissections.

Implications:

• Recognizing typical angiographic patterns aids in diagnosing these rare aneurysms.
• Proximal arterial occlusion offers a viable treatment option for vertebral artery dissecting aneurysms, potentially improving patient outcomes.
