Massive Pulmonary Embolism due to Inferior Vena Cava Thrombosis Related to Compression by Lumbar Artery Pseudoaneurysm. A Case Report and Review of Literature.

Lumbar artery pseudoaneurysm (LAPA) is a pathology infrequently described in the literature. The most frequent complications are the expansion and rupture of the pseudoaneurysm. Reports of association between PE with LAPA have not yet been described. We present a 53-year-old male patient with LAPA whose expansion caused compression of the inferior vena cava and subsequently PE. He underwent mechanical thrombectomy and inferior cava vein filter placement associated with embolization of the LAPA. Despite the severe clinical profile, the patient was discharged with a favorable postoperative course without complications. This case report also includes a review of the literature.
