Why is there a blood circulation problem in leg after surgical aneurysm?

A blood circulation problem in the leg after a surgical aneurysm can occur due to several factors, including disruption of blood flow during the procedure, damage to surrounding blood vessels, or the formation of blood clots. Surgical manipulation might also lead to the narrowing or blockage of arteries, impairing circulation. Additionally, post-operative inflammation and scar tissue formation can further obstruct blood flow. These complications can result in symptoms such as pain, numbness, or even ischemia in the affected leg.
