Women may get splenic aneurysms during pregnancy, and they are more common among women who have had many children.
While the risk of a rupture (when the aneurysm bursts) is low with peripheral aneurysms, they can lead to blood clots. Blood clots block blood flow or shower downstream.
If a clot blocks blood flow for an extended time, this can lead to tissue or organ loss.
Peripheral aneurysms may also put pressure on surrounding nerves or veins. This can cause pain, numbness, or swelling.
