Arterial dissection
An arterial dissection occurs when a tear develops in the inner lining of an artery, causing blood to enter the wall and split its layers. This can reduce or block blood flow to vital organs, leading to symptoms like pain, weakness, or even stroke, depending on the affected artery. Dissections can happen suddenly due to trauma or develop gradually from underlying conditions that weaken the arterial wall. Prompt diagnosis and treatment are essential to prevent serious complications, often involving medications to reduce blood pressure or surgery to repair the artery.
