Posterior Circulation Insufficiency

Posterior circulation insufficiency (PCI), also known as vertebrobasilar insufficiency (VBI), occurs when there is a reduction in blood flow to the back part of the brain, which includes areas responsible for vision, balance, and coordination. This condition can lead to a variety of symptoms and can be serious if not treated promptly.

Types of Posterior Circulation Insufficiency

1. Transient Ischemic Attack (TIA): A temporary reduction in blood flow causing short-term symptoms.
2. Stroke: A significant and prolonged reduction in blood flow leading to brain damage.
3. Chronic Posterior Circulation Insufficiency: Persistent poor blood flow causing ongoing symptoms.

Causes of Posterior Circulation Insufficiency

1. Atherosclerosis: Hardening of the arteries due to plaque buildup.
2. Blood Clots: Clots that block blood flow.
3. Arterial Dissection: A tear in the artery wall.
