Thank you for posting your query.
Tortuousity of the blood vessel refers to mild abnormal dilatation of the blood vessel, however, it is not similar to an aneurysm
. An aneurysm is an abnormal out-pouching of the artery
(a ballon like dilatation).
An aneurysm has a higher risk of rupture and causing brain haemorrhage (bleeding in the brain).
Tortuous vessel may predispose to a stroke
, as blood flow may be sluggish through a tortuous vessel leading to thrombosis
(clot formation). However, this risk is very small.
Wishing you good health,
