Posttraumatic Intrasplenic Pseudoaneurysm with High-Flow Arteriovenous Fistula: New Lessons to Learn.

Intrasplenic pseudoaneurysm is a potentially lethal complication of abdominal trauma. We present the case of a 33-year-old patient with this particular complication diagnosed by CT-scan. Selective embolization was not possible due to its extraordinarily large size and finally splenectomy was performed. We review the English literature and discuss the particular role of the interventional radiologist to treat this entity. The interventional radiologist is the specialist who better estimates the success of embolization or the risk and possibility of delayed splenic rupture. Embolization of the arterial tributary to the pseudoaneurysm should be considered as the treatment of choice only when the diagnosis is made before rupture of the spleen and only in selected cases. Splenectomy always remains as an alternative treatment for high-risk pseudoaneurysms.
