Pseudo aneurysm aneurysm false. Medical search. Frequent questions

Blunt or penetrating trauma can cause a disruption in the arterial wall, leading to a pseudoaneurysm. (wikipedia.org)
The diagnosis should be confirmed using Duplex ultrasonography, which will reveal arterial blood flow into the pseudoaneurysm. (wikipedia.org)
Since the pseudoaneurysm communicates with an artery through a hole in the arterial wall, a covered stent may be placed endovascularly across this hole to "exclude it," or to prevent it from receiving blood flow from the artery. (wikipedia.org)
The covered stent remains in place permanently, and the pseudoaneurysm, without a continuous flow of arterial blood, then thromboses. (wikipedia.org)
Complications include covered stent migration, persistent leakage of blood into the pseudoaneurysm, fracturing (breaking) of the stent, and infection of the stent or of the arterial insertion site. (wikipedia.org)
