RESUMO
Major injury of the innominate artery is traditionally treated with an open repair which is technically challenging, associated with large volumes of blood loss and prolonged operative times. Endovascular treatment with covered stent placement across the injury is an attractive alternative. However, placement of a single covered stent across the innominate artery bifurcation into one of its distal branches will not prevent bleeding because of retrograde perfusion from the unstented branch distal to the bifurcation. Here, we report a case of successful endovascular repair of one such injury involving the innominate artery bifurcation with ongoing extravasation into the mediastinum. The injury was successfully treated by utilizing 2 balloon-expandable covered stents placed in kissing fashion from the innominate artery into both of its distal branches. This technique of parallel covered stent placement across a bifurcation could effectively repair bifurcation injuries while maintaining patency of both distal branches.

Isolated innominate artery injury is very rare and accounts for less than 3% of recognized arterial injuries. Surgical exploration of the artery, especially at the origin of the artery from the arch of the aorta, is surgically challenging. Due to its rarity, any 1 surgeon's experience in dealing with innominate artery injury is bound to be limited. We report 2 cases of innominate artery injury post-blunt chest trauma. Both patients underwent thoracotomy and innominate artery Dacron graft repair and both had an uneventful postoperative course.

OBJECTIVE: Tracheoinnominate fistula (TIF) is a rare and frequently lethal complication of tracheostomies. Immediate bleeding control and surgical treatment are essential to avoid death. This report describes the successful endovascular treatment of TIF in a preschooler and reviews the literature concerning epidemiology, diagnosis, prophylaxis, and treatment of TIF in pediatric patients. CASE DESCRIPTION: A tracheostomized neurologically impaired bed-ridden three-year-old girl was admitted to treat an episode of tracheitis. Tracheostomy had been performed two years before. The child used a plastic cuffed tube continually inflated at low pressure. The patient presented two self-limited bleeding episodes through the tracheostomy in a 48h interval. A new episode was suggestive of arterial bleeding, immediately leading to a provisional diagnosis of TIF, which was confirmed by angiotomography, affecting the bifurcation of the innominate artery and the right tracheal wall. The patient was immediately treated by the endovascular placement of polytetrafluoroethylene (PTFE)/nitinol stents in Y configuration. No recurrent TIF, neurological problems, or right arm ischemia have been detected in the follow-up. COMMENTS: TIF must be suspected after any significant bleeding from the tracheostoma. Endovascular techniques may provide rapid bleeding control with low morbidity, but they are limited to a few case reports in pediatric patients, all of them addressing adolescents. Long-term follow-up is needed to detect whether stent-related vascular complications will occur with growth.

We report a case of a 24-year-old male patient with blunt brachiocephalic trunk injury, who was given low-dose dexmedetomidine (DEX) for 2 weeks to help smoothly pass the preparation period before the recanalization operation. Because the patient's vital signs were stable after the injury, the surgeon did not perform emergency surgery. Taking into account the characteristics of blunt brachiocephalic trunk injury, it is necessary to avoid damage to or even rupture of brachiocephalic trunk resulting from irritability and high blood pressure. Patients should be sedated to avoid hemodynamic fluctuations that may be caused by cerebral ischemia and restlessness, and based on the patient's neurological symptoms, prevention or treatment of perioperative neurocognitive disorders (PNDs) cannot be ignored. Therefore, the choice of drugs for bridging the preoperative preparation stage is crucial. DEX is an α2-adrenergic receptor agonist with antianxiety, analgesic, and sedative effects. It can also stabilize hemodynamics, regulate neuroinflammation, and provide neuroprotection. Instead of using either ß-adrenergic receptor antagonists or sedatives, the patient received only low-dose DEX during preoperative preparation. DEX achieved the effects of ß-adrenergic receptor blockers, vasodilators, and other sedatives, and it also had certain benefits for the patient's PND. In short, based on our understanding of the relevant physiological factors, risk factors of brachiocephalic trunk injury, and the effects of DEX, low-dose DEX provides a good option for preoperative management in a patient with blunt brachiocephalic trunk injury.

OBJECTIVE: To highlight the importance of imaging in reducing an accidental injury to the anomalous brachiocephalic trunk and its branches during tracheal surgery. CASE REPORT: This paper reports two cases of accidental injury to the great vessels in the neck during tracheal surgery. The first incident occurred during a repeat tracheostomy, when the right common carotid artery was injured. On reviewing the computed tomography images, the bifurcation of the brachiocephalic artery was seen to the left of the midline, and the right common carotid artery was adherent just below the tracheostomy site. The second incident happened during surgery for tracheal stenosis, when there was an inadvertent injury to the main brachiocephalic trunk, which was adherent to the trachea in the lower neck region. CONCLUSION: For airway surgeons, radiological assessment of vascular structures in relation to the trachea prior to surgery is as important as the endoluminal airway assessment for the best outcome.

Innominate artery (IA) injury is a rare entity with most patients dying before reaching the hospital. While open surgery remains the standard treatment, the endovascular approach is attractive as it may reduce perioperative morbidity and mortality. We report a case of IA blunt injury extending to the subclavian artery with pseudoaneurysm formation successfully treated with covered stenting of IA and its bifurcation. A 49-year-old male was admitted after suffering multiple trauma due to a high energy impact motorcycle crash. In the emergency room, the patient was hypotensive with a Glasgow coma score of 15. On physical examination, he had right peri-orbital ecchymosis, left otorrhagia and an open patella fracture. The computed tomographic angiography (CTA) revealed enlargement of the mediastinum and a 29 mm pseudoaneurysm involving the right brachiocephalic trunk and its bifurcation. Under general anesthesia, a covered balloon-expandable stent (CBES) was then placed in the IA followed by kissing stent of its bifurcation with an additional 2 covered balloon-expandable stents. Final subtraction angiography demonstrated complete pseudoaneurysm exclusion and stent patency without additional complications. No neurologic deficits or other intervention-related complications were found in the postoperative period. At 10 months follow-up, the patient remained asymptomatic and with palpable distal pulses. Endovascular management of IA injury may provide a good alternative to open surgery with low perioperative morbidity and mortality.

BACKGROUND: Iatrogenic acute aortic dissection (AD) is an extremely rare but devastating complication during cardiac catheterization. It can be treated conservatively if it develops in a retrograde form or manifests as an intramural hematoma (IMH) with a micro-intimal tear in the absence of instability. However, only a few reports exist on its natural course and long-term outcomes. CASE PRESENTATION: A 78-year-old woman presented to the emergency department with acute chest discomfort. Elective cardiac catheterization was performed via the right radial artery. The patient's brachiocephalic artery was so tortuous that the hydrophilic soft guidewire had to be exchanged for a stiffer one. However, the stiff wire caused the dissection of a tortuous brachiocephalic artery that extended from the sinuses of Valsalva to the proximal descending aorta. Emergent computed tomography showed crescentic aortic wall thickening without a dissection flap. The patient had cardiac tamponade and a gradually thickening thrombosed false lumen. Although the patient was unstable during the first 2 weeks, she was stabilized during hospital stay with only conservative treatment. Consequently, she has been well for over 5 years. CONCLUSIONS: Even though the patient showed ominous findings, a good prognosis was expected because the AD was mainly retrograde. Furthermore, the thrombosed false lumen mimicked an IMH on imaging. To the best of our knowledge, this is the first report of an extensive iatrogenic AD originating from the brachiocephalic artery during right transradial catheterization that was treated conservatively despite clinical instability.

OBJECTIVE: To evaluate the feasibility, safety, and efficacy of an accurate kissing Viabahn stent technique to manage injuries near the innominate artery bifurcation. METHODS: This retrospective study included patients with injuries near the innominate artery bifurcation who were treated with an accurate kissing Viabahn stent technique. Perioperative and follow-up data were extracted and analysed. RESULTS: A total of 10 patients were included (mean age, 52.8 years; six male and four female patients) with injuries at the following sites: the distal end of the innominate artery (n = 2), the innominate artery bifurcation (n = 5), the root of the right common carotid artery (n = 2) and the origin of the right subclavian artery (n = 1). All were successfully treated with the accurate kissing Viabahn stent technique. During follow-up (mean duration, 16.8 months), there were no complications, such as right upper limb ischaemia, neurological dysfunction, stent occlusion or migration. CONCLUSIONS: The accurate kissing Viabahn stent technique to manage injuries near the bifurcation of the innominate artery was safe and effective, with good perioperative and long-term follow-up results.

PURPOSE: To discuss and share the experience of treatment of traumatic innominate arterial injury. METHODS: A retrospective analysis was performed on patients with innominate arterial injuries admitted from January 2016 to July 2018 at the department of vascular surgery, Beijing Jishuitan Hospital, China. All the arterial injuries were confirmed by arteriography. Clinical data including mechanism of injury, type of injury, demographics, concomitant injuries, time interval from trauma to blood flow reconstruction, and operation methods were collected. Follow-up program included outpatient visit and duplex-ultrasonography. SPSS version 23.0 was adopted for data analysis. Categorical variables are presented as number and/or frequency and continuous variables as mean ± standard deviation. RESULT: Altogether 7 patients were included and 6 (85.7%) were male. The mean age of patients was (29.43 ± 7.98) years, range 19-43 years. Six patients had isolated innominate arterial injuries and the rest 1 combined innominate arterial and vein injuries. The injury causes were road accidents in 3 patients, stab wound in 2, gunshot wound in 1, and crush injury in 1. All the 7 patients presented hemorrhagic shock at admission, which was timely and effectively corrected. No perioperative death or technical complications occurred. Intimal injury (n = 2) and partial transaction (n = 2) of the innominate artery were treated with covered stents. Two patients with complete transection of artery received vascular reconstruction by artificial grafts. One patient with partial transaction received balloon dilation and open surgical repair (hybrid operation). The mean time interval from trauma to blood flow reconstruction was (4.27 ± 0.18) h, range 4.0-4.5 h; while the operation time was (48.57 ± 19.94) min, range 25-75 min. Cerebral infarction occurred in one patient with brain injury due to anticoagulation contraindication. The average follow-up was (13.29 ± 5.65) months, range 6-24 months. No severe stenosis, occlusion, and thrombosis of covered stents or artificial vessels were found by color Doppler ultrasound. CONCLUSION: Urgent control of hemorrhage and restoration of blood supply are critical for the treatment of traumatic innominate arterial injury. Endovascular therapy is a feasible and effective method with short operation time and less trauma.

Blunt injuries of the great vessels arising from the aortic arch are usually fatal. The innominate artery lesions represent the most common site of injury after the aortic isthmus distal to the left subclavian artery. Injuries are usually located at the origin of the vessel from the aortic arch, especially in patients with bovine aortic arch. Open traditional repair is a successful but invasive treatment, with long hospital stay and different possible complications. Although a bovine aortic arch presents an increased technical challenge, it is possible to achieve a complete and safe repair of the innominate artery injuries through a total endovascular treatment, with important reduction of risks and complications related to operation, compared to traditional open repair. We report the case of a 62-year-old man in our hospital with a posttraumatic pseudoaneurysm of the innominate artery in the setting of a bovine aortic arch, associated with a transection of the descending thoracic aorta. In the urgent setting, the patient was submitted to a kissing stent of innominate artery-left common carotid artery and deployment of thoracic endoprosthesis to exclude the aortic transection, with good final result.

Innominate artery pathology is traditionally treated with open surgical repair and is associated with significant morbidity. No dedicated endovascular solution exists for this anatomic location. We report a series of 3 cases of successful management of innominate artery injuries using an off-label, modified Zenith ESLE stent graft (Cook Medical, Bloomington, IN). Two patients presented with pseudoaneurysms after attempted central venous catheterization, and 1 patient developed a tracheo-innominate fistula. Access was obtained in a retrograde fashion via the right common carotid artery in 2 cases, and via the right axillary artery in the other. Additional anatomic considerations included a prior sternotomy in 2 cases and a bovine arch in 2 cases. Due to the emergent nature of the cases, no cerebral protection maneuvers were taken. The ESLE limbs are of uniform diameter with 3 Z-stent wireforms and measure 55 mm in length. Removal of the distal stent reduces the length to 38 mm. Fourteen- to 18-mm diameter grafts were used. All 3 cases resulted in technical success with complete exclusion of the defect. There were no new neurologic deficits and all patients recovered uneventfully. This approach represents an effective off-label solution for what frequently presents as an emergent problem. In 2 cases, it obviated the need for a complicated redo sternotomy and facilitated endovascular repair in a vessel for which there was no indicated off-the-shelf conduit. Modification of existing devices successfully addressed the need for a nontapered graft of short length and moderate vessel diameter and allowed for minimally invasive treatment of anatomically complex pathology.

Anterior mediastinal tracheostomy (AMT) is established after division of the retrosternal trachea following resection of extended upper airway malignancies, stomal recurrences, or cervicomediastinal exenteration. AMT is occasionally performed for nonmalignant diseases. Starting in the 1980s, the use of a pectoralis major myocutaneous island flap reduced the mortality attributable to innominate artery rupture previously reported in historical series. Recent advances in the vascular reconstruction of supra-aortic trunks could allow future development of AMT as salvage surgery. On the other hand, construction of the stoma using free flap procedures and advances in chemoradiotherapy could simultaneously reduce the indication for AMT.

BACKGROUND: Innominate artery aneurysm (IAA) is a rare cervical artery aneurysm. Although atherosclerosis is its most common cause, IAAs due to cervical injury are often reported. Operative indications for IAAs include rupture or symptomatic aneurysm, saccular aneurysm, aneurysm with a diameter of 3 cm or greater, and aneurysmal change of the origin of the innominate artery. Although the ligature of the innominate artery or open surgical repair is well described, the usefulness of endovascular repair has also recently been reported. Herein, we report a case of traumatic IAA with infection in the cervical region after tracheostomy. CASE PRESENTATION: A 40-year-old man with cholecystolithiasis planned to undergo laparoscopic cholecystectomy at another hospital. Urgent tracheostomy was performed because of laryngeal edema at the induction of general anesthesia. Enhanced computed tomography angiography 1 week after the tracheostomy revealed a saccular IAA. The patient was deemed to be at high risk for aneurysm rupture and was referred to our hospital. Preoperative Matas test, Allcock test, and innominate arterial stump pressure measurement were performed to assess the cerebral blood flow and ischemic tolerance of the brain. These examinations showed the patency of the circle of Willis. An axillo-axillary artery bypass with coil embolization of the innominate artery was performed to avoid postoperative vascular graft infection. No postoperative complications such as infection or cerebral infarction occurred. Magnetic resonance imaging angiography performed 6 months after surgical treatment showed that the aneurysm had disappeared, and patency of the bypass graft was present. There were no postoperative complications, such as neurological deficits or graft infection, at more than 5 years after surgery. CONCLUSIONS: We report a successfully treated case of IAA after tracheostomy. Axillo-axillary artery bypass with coil embolization of the innominate artery is an effective treatment of IAA with cervical infection.

Cervical artery dissection is a frequent cause of stroke, more so in young patients. Innominate artery (IA) dissection is uncommon, and most often associated with dissection of other major arteries like the aorta. The leading cause of IA injury is high-energy thoracic trauma, as in motor vehicle crash. IA dissection after blunt trauma is rare. We described here the unusual case and iconography of an isolated IA dissection after rifle recoil initially presenting as a stroke.

BACKGROUND: Patients with stable blunt great vessel injury (GVI) can have poor outcomes if the injury is not identified early. With current pediatric trauma radiation reduction efforts, these injuries may be missed. As a known association between scapular fracture and GVI exists in adult blunt trauma patients, we examined whether that same association existed in pediatric blunt trauma patients. METHODS: Bluntly injured patients younger than 18 years old were identified from 2012 to 2014 in the National Trauma Data Bank. Great vessel injury included all major thoracic vessels and carotid/jugular. Demographics of patients with and without scapular fracture were compared with descriptive statistics. The χ test was used to examine this association using SAS Version 9.4 (SAS Institute, Inc, Cary, NC). RESULTS: We found a significant association between pediatric scapular fracture and GVI. Of 291,632 children identified, 1,960 had scapular fractures. Children with scapular fracture were 10 times more likely to have GVI (1.2%) compared to those without (0.12%, p < 0.0001). Most common GVI seen were carotid artery, thoracic aorta, and brachiocephalic or subclavian artery or vein. Children with both scapular fracture and GVI were most commonly injured by motor vehicles (57% collision, 26% struck). CONCLUSIONS: Injured children with blunt scapular fracture have a 10-fold greater risk of having a GVI when compared to children without scapular fracture. Presence of blunt traumatic scapular fracture should have appropriate index of suspicion for a significant GVI in pediatric trauma patients. LEVEL OF EVIDENCE: Epidemiologic and prognostic study, level III; Therapeutic, level IV.
