Traumatic rupture of the thoracic aorta: time to diagnosis and treatment.

摘要

Survival of patients with traumatic rupture of the thoracic aorta (TRTA) depends on early surgical repair. Six cases of TRTA were treated at our institution in 7 years. Time to diagnosis was 1.5, 3, 4, 36, 91 and 140 hours (mean = 46 hours). Diagnosis was made by computed tomography in one and by angiography in five cases. Time from arrival to treatment was 3, 9, 5, 46, 117 and 152 hours (mean = 55 hours). All six patients were treated by clamp and suture technique, with a mean cross clamp time of 48 minutes. Significant delay in diagnosis and treatment occurred in three patients. The reasons for delay were unrecognized signs for TRTA on the initial chest X-ray, a false-negative result of transoesophageal echography and not considering the diagnosis of TRTA. The diagnosis of TRTA requires a high index of suspicion and should always be considered in victims of high impact trauma.
