[Operation for a giant pseudoaneurysm of the aortic arch without artificial circulation]

Presented herein is a variant of surgical management of a patient with a giant false aneurysm of the aortic arch in the posterior mediastinum. Using the technique of temporary bypass or temporary "debranching" made it possible to carry out a reconstructive intervention without the use of an artificial circulation apparatus. This technique also decreases the necessity of using heparin, thus diminishing the risk of blood loss both during the operation and in the postoperative period. The described variant of the operation for a false aneurysm of the aortic arch extends and supplements the surgeon's capabilities of performing interventions on the aortic arch in the absence of a possibility of using an artificial circulation apparatus both in a scheduled and emergency situation.
