Percutaneous Treatment of Multiple Recurrent Thromboembolization from a Descending Thoracic Aortic Intimal Sarcoma.

Aortic intimal sarcomas are rare tumors that may result in distal embolic ischemia. Here, we present a patient who presented with crescendo lower extremity and mesenteric ischemic events from malignant macroembolism. Management with percutaneous pharmacomechanical thromboembolectomy enabled restoration of distal perfusion and minimally invasive collection of tumor sample to confirm the suspected diagnosis of aortic sarcoma.

Nonoperative Management of Traumatic Aortic Pseudoaneurysms.

Background: Current blunt thoracic aortic injury (BTAI) guidelines recommend early repair of traumatic pseudoaneurysms (PSAs) due to risk for subsequent aortic rupture. Recent analyses indicate that early repair is required only in the setting of high-risk features, while delayed repair is safe and associated with lower morbidity and mortality in appropriately selected patients. To evaluate the appropriate indications for nonoperative management (NOM) of traumatic PSAs, we performed a systematic review of studies reporting outcomes for this management strategy.
