Mechanical Thrombectomy Complicated by Pulmonary Artery Pseudoaneurysm Treated With Endovascular Thrombin Injection.

Pulmonary thrombectomy for acute pulmonary arterial embolism has emerged as an effective endovascular therapy for high-risk patients. While the procedure is typically performed safely and efficaciously, given the nature of the treatment, complications may rarely occur. Pulmonary pseudoaneurysm is a rare condition occurring in a variety of settings, including pulmonary thrombectomy. To our knowledge, we present the first published case of pulmonary artery pseudoaneurysm following percutaneous thrombectomy, along with its successful endovascular management.
