Traumatic rupture of the thoracic aorta

Area of Science:

• Cardiovascular Surgery
• Trauma Surgery
• Thoracic Surgery

Background:

• Traumatic rupture of the thoracic aorta is a life-threatening injury.
• Prompt diagnosis and surgical intervention are critical for patient survival.
• Delayed presentation of aortic rupture can influence surgical outcomes.

Purpose of the Study:

• To evaluate the surgical treatment outcomes for traumatic thoracic aortic rupture.
• To analyze the impact of delayed surgical repair on patient survival.
• To assess the efficacy of partial pulsatile left heart bypass in aortic repair.

Main Methods:

• Retrospective analysis of 22 patients with traumatic thoracic aortic rupture treated between 1970 and 1980.
• Classification of patients into emergency, delayed, and chronic repair groups.
• Surgical repair utilizing partial pulsatile left heart bypass or controlled blood pressure with nitroprusside.

Main Results:

• Overall hospital mortality was 34% in the emergency group versus 0% in delayed/chronic groups.
• Ruptures were predominantly located at the aortic isthmus (21/22 cases).
• No instances of paresis or paraplegia were observed post-surgery.

Conclusions:

• Surgical treatment is essential for traumatic thoracic aortic rupture, particularly in emergency situations.
• Delayed and chronic repair of aortic rupture demonstrate favorable outcomes with 0% mortality.
• Repair of chronic post-traumatic false aneurysms is recommended due to unpredictable prognosis.
