Objective: Retrospective evaluation of long term results after direct suture repair of chronic traumatic aneurysm of the aortic isthmus. Methods: From March 1979 to June 1998, a total of 19 patients with chronic traumatic aneurysm of the aortic isthmus were operated on, among whom 12 (63%) underwent direct suture. These 12 patients (age ranging from 19 to 68 years; mean 34.2 years) constitute the subject of this study. All but one suffered traffic accidents. Mean delay between trauma and surgery was 4 years (range 3 months to 12 years). All patients underwent a left posterolateral thoracotomy through the fourth intercostal space. Extracorporeal circulation for spinal cord protection was installed in six patients (five ilio-iliac shunts, one atrio-iliac shunt). Aortic rupture was partial in five and circumferential in seven patients. The mean clamping time was 25 min. The absence of loss of aortic substance and a careful mobilization of the aorta made the repair by direct suture easier; this technique could thus be achieved in 63.2% of all 19 patients operated on of chronic traumatic aneurysm within the same period. Results: There was no in-hospital death and no postoperative paraplegia. With a median follow-up of 15 years 3 months (ranging from 22 to 10 years), there were no late complications. Chest X-ray was normal in all patients; eight of them underwent a control angiography between 18 and 72 postoperative months; all these angiographies but one (20% stenosis without gradient) demonstrated a normal appearance of aortic isthmus. Conclusion: Direct suture for repair of chronic traumatic thoracic aneurysm is a safe procedure: longterm outcome was excellent and the complications observed with prosthetic grafts or with aortic endoprosthetic stent-grafts were avoided. q 2002 Elsevier Science B.V.
