What is a digital artery aneurysm?

A digital artery aneurysm is a localized dilation or bulging of a digital artery, which supplies blood to the fingers. This condition can result from various factors, including trauma, atherosclerosis, or genetic predispositions. Symptoms may include pain, swelling, or a pulsating sensation in the affected digit. If left untreated, it can lead to complications such as thrombosis or ischemia.
