Endovascular treatment for traumatic thoracic aortic pseudoaneurysm: a case report

Post-traumatic pseudoaneurysm of the descending aorta

High-energy deceleration injuries of the thoracic aorta are associated with high mortality. But among long term survivors, just 2 %-5 % of traumatic aortic injuries fail initial detection and are discovered later (Pozek et al., 2012 [1]). We present a rare case of pseudoaneurysm of the descending aorta in a female with a history of chest blunt trauma 45 days before who presented with chronic severe cough and vocal hoarseness that was treated with endovascular intervention in our center.

Complex aortic-arch pseudoaneurysm with aorto-innominate vein fistula in a case of traumatic chest injury

A patient in his late 30s presented with issues of retrosternal chest pain and palpitations. He had sustained a splinter injury to the left hemithorax a year ago for which he had been managed with a tube thoracostomy. During subsequent evaluations, he was found to have atrial fibrillations and a CT angiography revealed an arch of the aorta pseudoaneurysm with a fistulous communication with the innominate vein, which being a rare condition has no established treatment protocols. Endovascular salvage of the condition required an aortic Ishimaru zone 2 deployment of the thoracic endovascular aortic repair stent graft to provide an adequate landing zone. The elective left subclavian artery revascularisation was obtained by a left carotid artery to left subclavian artery bypass. Post procedure there was complete exclusion of the pseudoaneurysm sac, and the fistulous aorto-venous communication inflow tract. The patient recuperated well and has returned to full active duties.

Traumatic rupture of the thoracic aorta: A life-threatening emergency and the role of endovascular repair

Traumatic rupture of the thoracic aorta is a rare condition, with a high mortality rate. Over the last 2 decades, strategies for managing aortic injury caused by blunt chest trauma have changed substantially, resulting in significantly improved outcomes. The recent development of endovascular repair offers a less invasive alternative to conventional open repair, particularly in patients with multiple injuries. Here, we report the case of a 31-year-old man who was referred to our emergency department with blunt chest trauma following a motorcycle-truck collision. Computed tomography confirmed acute traumatic rupture of the thoracic aorta, and the patient was successfully treated with endovascular repair.

Endovascular Repair for Thoracic Aortic False Aneurysms: Single-Center Experience in 102 Patients

BACKGROUND

Thoracic aortic false aneurysm is unusual and experience with endovascular repair is limited. We evaluate the efficacy of endovascular repair in patients with thoracic aortic false aneurysms.

METHODS

The early and midterm outcomes of endovascular repair in 102 patients with thoracic aortic false aneurysms were analyzed.

RESULTS

There were 80 men and 22 women (age 54.9 ± 13.7 years). Emergent or urgent endovascular repair was done in 19 cases (18.6%) and elective in 83 (81.4%). Procedure was successful in 99.0%. Early death occurred in 4 patients (3.9%). No early death occurred in elective patients. Early complications occurred in 7 patients (6.9%). Follow-up was complete in 100% for 24.0 ± 18.5 months (range, 1.5 to 67.3). Fourteen late deaths occurred (13.7%). Late events occurred in 9 patients (8.8%). Survival at 6 month, 1 year and 3 years was 90.7%, 86.7% and 84.5%, respectively.

CONCLUSIONS

Satisfactory early and midterm outcomes have been achieved with endovascular repair in this series. Although emergent or urgent patients had higher rates of early mortality and morbidity, the majority of them achieved stable late survival as long as they survived at least 6 months. These results argue favorably for use of endovascular repair in the management of patients with thoracic aortic false aneurysms.
