EMBOLIZATION OF LUMBAR ARTERIES
Rupture of lumbar artery is a rare complication. If this pathology is not timely diagnosed, shock and the potential life-threatening retroperitoneal bleeding are possible. This article presents two clinical cases in which patients were treated with embolization. One patient suffered a lumbar artery injury, in another case developed a spontaneous lumbar arterial hemorrhage complicating heparin therapy. The diagnosis was suggested by a computed tomography scan. Angiography demonstrated pseudoaneurysm in one patient, and in that case coils were used; in another patient with active extravasation particles were applied. The use of different embolic materials allows to stop the bleeding from the lumbar arteries, to eliminate false aneurysm, and to stabilize patient's condition.
