Pulmonary artery stump thrombosis

Pulmonary artery stump thrombosis describes thrombus formation occurring at the site of the pulmonary arterial stump, a complication following lobectomy or pneumonectomy. It is usually discovered as an incidental finding on routine follow-up chest CT scans.

The prevalence of pulmonary artery stump thrombosis after pneumonectomy is approximately 12% 1

Is thought to be an in situ thrombus caused by stasis of blood flow 2. Although the right pulmonary stump is longer than the left postpneumonectomy, which may promote a greater degree of stasis, interestingly studies have been inconclusive regarding whether they occur more commonly on one side or the other 8.

Some publications suggest anticoagulation to be considered for convex stump thrombus or a new stump thrombus in the context of declining pulmonary status.
