Two-year follow-up after treatment of an aortic transection in the presence of an aberrant right subclavian artery.

OBJECTIVES: An aberrant right subclavian artery (ARSA) is one of the most common anatomic variants of the aortic arch. The combination of an ARSA and a transection is naturally rare. METHODS: This case report describes the treatment of a transection in the presence of an ARSA and the follow-up of two years. RESULTS: We successfully treated the contained rupture with a stentgraft. Both subclavian arteries had to be covered in the emergency setting. At the two-year follow-up, the patient did not suffer from any neurological impairment. CONCLUSIONS: In emergency settings, primary cover of both subclavian arteries with a stentgraft can be performed in individual cases after risk assessment. Severe complications such as development of upper limb ischaemia, ASAS or reduced perfusion of the posterior cerebral circulation should be considered in treatment planning.

Laparotomy management of diaphragmatic and hollow viscera rupture combined with thoracic endovascular aortic repair after a traffic accident: A case report.

INTRODUCTION: Road traffic incidents are the most common cause of multiple organ trauma in low- and middle-income countries. Multiple blunt intra-abdominal organs that rupture in conjunction with a ruptured aorta are terrible and rare. CASE PRESENTATION: A 65-year-old man sustained critical injuries during a traffic collision between a motorcycle and truck. The Injury Severity Score was 42 points,. After open abdominal exploration, we repaired the left diaphragmatic rupture with a 13-cm-long tear of IV grade (American Association for the Surgery of Trauma), resected partial small bowel, simple suture of the transverse colon, and Hartmann procedure in the descending colon. Thoracic endovascular aortic repair (TEVAR) was performed 22 h after laparotomy. Reconstruction of the head depicting a cheekbone fracture and inferior to the left orbital bone was performed on the 14th day. The patients survived and were discharged from the hospital, at 22 days without morbidity or mortality. DISCUSSION: Diaphragmatic rupture provides a signal to relate head, thoracic, and abdominal blunt trauma. If the patient sustains more serious life-threatening injuries that require emergency laparotomy or craniotomy, and aortic repair may be delayed. Laparotomy is the best initial surgical method in this case. TEVAR is a feasible and gold standard procedure for the treatment of patients with the necessary indications. CONCLUSION: It is essential to evaluate the level of organ damage to properly coordinate the specialists. The timing of the operation and therapeutic alternatives should be decided for each patient.

Endovascular stenting of blunt aortic isthmus rupture in a 5-year-old child.

Blunt traumatic aortic tear is an extremely rare and life-threatening paediatric emergency. Percutaneous repair is highly debateable in children due to anatomic limitations. Herein, we report an important case of a 5-year-old boy diagnosed with grade 3 aortic isthmus disruption following fifth-floor defenestration. The 96-h control computerized tomography (CT) scan showed an increase in the pseudoaneurysm size with small active bleeding motivating endovascular covered stenting that was safely and efficiently performed with good outcomes.

Identification of aortic injury site using postmortem non-contrast computed tomography in road traffic accident.

In high-speed motor vehicle accidents, it is necessary to investigate the manner of death. Postmortem computed tomography (PMCT) provides important information on the mechanism of death, but identification of the aortic injury is still challenging on non-contrast PMCT. A man in his 50s had multiple injuries on the face and chest in the high-speed motor vehicle accident. The traumatic aortic rupture was clearly depicted on thin-slice and multiplanar reformation PMCT images. Traumatic aortic disruption was confirmed by forensic autopsy. The high contrast between the aortic wall and the lumen visualized the traumatic rupture in the distal aortic arch. For the evaluation of aortic rupture on PMCT, it may be important to trace the continuity of the high-density aortic wall by reviewing thin-slice CT and multiplanar reformation images.

Delayed presentation of a traumatic descending thoracic aorta aneurysm as an aorto-oesophageal fistula.

Aorto-oesophageal fistula is a rarely described but life-threatening complication presenting with upper gastrointestinal haemorrhage. We present a case of a 58-year-old gentleman who presented to a peripheral hospital with a short duration of haematemesis and melaena and recent onset symptoms of dysphagia. This gentleman had a past medical history of alcohol excess and a history of trauma following a road traffic accident 38 years ago. Initial computer tomography scan demonstrated a large saccular aneurysm arising from the descending thoracic aorta adjacent to the oesophagus. The patient underwent radiological stenting of the large aneurysm with thoracic endovascular aortic replacement procedure. Follow-up computerized tomography (CT) angiography demonstrated satisfactory appearances of the thoracic aortic stent graft with no evidence of endo-leak. The triad of dysphagia, occult gastrointestinal blood loss and CT findings of a large aneurysm should prompt diagnosis or aorto-oesophageal fistula until proven otherwise.

[Traumatic aortic rupture - diagnosis and managment]. / Die traumatische Aortenruptur.

Road traffic accidents are the main cause of traumatic aortic ruptures, mostly in combination with other severe injuries. The pre-hospital mortality rate is high. Suspected aortic trauma, following a high traumatic aortic injury score, is an indication for computer tomography. Injuries are triaged and the treatment priority of the aortic trauma is ascertained based on the severity of the aortic and concomitant injuries and the condition of the patient. Until definitive treatment of the aortic lesion is completed, the blood pressure of the patient must be kept low. Grade I and II lesions can be managed under strict monitoring with initial conservative treatment in individual cases. Grade III (contained perforation) and grade IV (open rupture) lesions need surgical or interventional treatment as swiftly as possible. In selected cases, a delayed treatment can also be advantageous.The endovascular stent graft therapy has established itself as the preferred form of treatment.

Successful simultaneous repair of traumatic aortic and right atrium ruptures.

A 63-year old woman was transferred to our hospital due to a motor vehicle accident. Enhanced computed tomography showed aortic arch intramural haematoma and pericardial effusion. The patient lost consciousness, and we thought that the cardiac tamponade was indeed due to intrapericardial rupture of the aorta. The emergency operation was started via a median sternotomy, and the femoral vessels were simultaneously exposed for possible peripheral cannulations. After cardiopulmonary bypass was started through the peripheral cannulations, we fully opened the pericardium and identified bleeding from a 2-cm tear in the right atrium. The culprit lesion was repaired using a 4-0 polypropylene suture with a felt strip. Next, total arch replacement with a four-branched knitted prosthetic graft was performed. Over two-thirds of the intima was circumferentially ruptured at the level of the aortic isthmus. Postoperative neurological complications did not arise.
