Vertebral artery injury

BACKGROUND: The literature documents that laminoforaminotomy (CLF), whether performed open, minimally invasively, or microendoscopically, is safer than anterior cervical diskectomy/fusion (ACDF) for lateral cervical disease. METHODS: ACDF for lateral cervical disc disease and/or spondylosis exposes patients to multiple major surgical risk factors not encountered with CLF. These include; carotid artery or jugular vein injuries, esophageal tears, dysphagia, recurrent laryngeal nerve injuries, tracheal injuries, and dysphagia...

BACKGROUND: Three-point seat belt restraints have been attributed to blunt cerebrovascular injury (BVCI), injury to the carotid or vertebral arteries. Although previous studies have not found a seat belt sign to be a significant predictor for BCVI, it is still used to screen patients for BCVI. OBJECTIVE: This study aims to determine risk factors for BCVI within a cohort of patients with seat belt signs. METHODS: We conducted a retrospective cohort study using our institutional trauma registry and included patients younger than 18 years with blunt trauma who both had a computed tomography angiography (CTA) of the neck performed and had evidence of a seat belt sign per the medical record...

Vertebral artery （VA）Aneurysms involving the origin of the posterior inferior cerebellar artery (PICA) ,occasionally, induce cerebellum and brainstem infarction due to intraluminal thrombus and calcific VA stenosis. At times, vessel occlusion and revascularization is necessary for successful obliteration of these aneurysms.2 The occipital artery (OA) is often the preferred donor graft for lesions of the posterior fossa. Although most OA-PICA bypasses can be performed using the p3 segment as the recipient site for an end-to-side anastomosis, a more feasible alternative to conventional OA-p3 PICA bypass in cases of high-riding caudal loops , aberrant anatomy or p3 multiple perforators is to free the p1 PICA, transpose it away from the lower cranial nerves, and perform an end-to-end OA-p1 PICA bypass instead...

Background and Objectives : Traumatic vascular injuries of the head and neck pose significant treatment challenges due to the complex anatomy, diverse clinical presentation, and mostly emergent nature. Endovascular treatment increasingly complements traditional surgical approaches. This study aimed to report our 10-year experience in treating traumatic vascular injuries of the head and neck with endovascular therapy and to determine the effectiveness of endovascular treatment. Materials and Methods : A retrospective analysis of 21 patients treated for head and neck vascular injuries between May 2011 and April 2021 was performed...

OBJECTIVE: Vertebro-vertebral arteriovenous fistulae (VVFs) are a rare disorder characterized by a direct shunt between the extracranial vertebral artery and the veins of the vertebral venous plexus. This study aims to comprehensively review the characteristics and outcomes of endovascular treatments for VVFs at our center. METHODS: A retrospective review was conducted on 14 patients diagnosed with a VVF who underwent endovascular treatment at Siriraj Hospital from January 2000 to January 2023...

OBJECTIVE: Modern combat-related vertebral artery (VA) injuries are increasingly being diagnosed, but the management of such injuries remains controversial. The authors report the frequency and characteristics of combat-related penetrating VA injuries and the indications for endovascular treatment, as well as analyze their treatment outcomes. METHODS: A 1-year prospective study was completed at a civilian medical center in Dnipro, Ukraine, in all patients with VA injuries sustained during the Russian invasion in the 1st year of war...

Duplication of the vertebral artery is a very rare vascular variant. We describe a case of a duplicated left vertebral artery. Computed tomography (CT) angiography examination of the head and neck vessels of a 63-year-old man with a history of imbalance was undertaken. A duplicated left vertebral artery was incidentally noted. The medial limb directly originated from the arcus aorta between the left common carotid artery and the left subclavian artery. The lateral limb originated from the proximal left subclavian artery as the first branch and entered the transverse foramen of the C6 vertebra as usual...

The study aimed to provide physician modified fenestration (PMF) on a single-branched stent for the aortic arch (Castor) to protect the isolated left vertebral artery (ILVA) during thoracic endovascular aortic repair (TEVAR). Patients who underwent TEVAR involving ILVA reconstruction through PMF performing on the Castor branched stent were included in a retrospective, multi-centre study from June 2018 to December 2022. In these patients, all proximal landing zones of "Castor" were positioned in Ishimaru zone 2a...

INTRODUCTION: Traumatic vertebral artery dissections resulting in stroke are relatively rare occurrences, especially in the absence of classic physical examination findings. CASE REPORT: We present the case of a 30-year-old male with chest pain following a car axle falling onto his chest while trying to change a tire. He was discharged from the emergency department after having a negative workup for thoracic injury. Six hours later, the patient returned with headache and was found to have a cerebellar stroke secondary to vertebral artery dissection...

BACKGROUND: There is no established opinion regarding embolization of asymptomatic traumatic vertebral artery injuries that do not require cervical spine repair and fixation. CASE DESCRIPTION: A 78-year-old man fell backward from a height of about 1 m and was rushed to his previous hospital. He had a fracture of the left transverse process of the 6th cervical vertebra. Six hours after the trauma, he became unconscious; magnetic resonance angiography showed occlusion of the left vertebral and basilar arteries, and he was transferred to our hospital...

Blunt vertebral artery injuries (BVAI) associated with cervical spine fractures are often problematic due to symptoms of occlusion. Denver grade V cases, in which the vertebral artery is transected, are rare but often fatal, and treatment has rarely been reported. We encountered a case of hemorrhagic shock due to an injury to a branch of the vertebral artery associated with an upper cervical spine fracture. Transcatheter arterial embolization was performed successfully to achieve hemostasis, requiring superselective arterial embolization to preserve the main trunk of the vertebral artery...

Chiropractic cervical spinal manipulations have several complications and can result in vascular injury, including traumatic dissection of the vertebral arteries. A 43-year-old woman was admitted to the emergency department after performing a self-chiropractic spinal manipulation. She experienced headache and vomiting and was unresponsive with severe hypertension at the time of hospital admission. Clinical computerized tomography angiography showed narrowing of the right vertebral artery but was inconclusive for dissection or thrombosis...

INTRODUCTION: Blunt cervical injuries rarely cause vertebral artery injuries (VAIs), such as vertebral artery (VA) dissection or occlusion. To prevent subsequent embolic infarction, embolization of the injured VA is needed before surgical fixation of the cervical spine. However, evidence on endovascular treatment for asymptomatic low-grade VAIs with blunt traumatic cervical injury is insufficient. CASE REPORT: In the present case, a 79-year-old Japanese man presented tetraparesis after falling while walking...

BACKGROUND & OBJECTIVES: Blunt cerebrovascular injury (BCVI) includes carotid and/or vertebral artery injury following trauma, and conveys an increased stroke risk. We conducted a systematic review and meta-analysis to provide a comprehensive summary of prognostic factors associated with risk of stroke following BCVI. METHODS: We searched the EMBASE and MEDLINE databases from January 1946 to June 2023. We identified studies reporting associations between patient or injury factors and risk of stroke following BCVI...

BACKGROUND: Hemothorax occurs in approx. 0.4% of all chest injury patients, but hemothorax due to a thoracic vertebral fracture is rare. CASE PRESENTATION: A 76-year-old Japanese man was transported to our hospital for right hemothorax due to a car accident. We performed emergency hemostasis surgery and tried to stop the bleeding by several methods, but it was difficult to control the bleeding because the bleeding point was an artery branch that runs in front of the vertebral body...

OBJECTIVE: Left vertebral artery revascularization is indicated in surgery involving Zone 2 of the aortic arch and is typically accomplished indirectly via subclavian artery revascularization. For aberrant left vertebral anatomy, direct revascularization is indicated. Our objective was to compare the outcomes of direct vertebral artery revascularization with indirect subclavian artery revascularization for treating aortic arch pathology and to identify predictors of mortality. METHODS: A retrospective cohort study was conducted at a single tertiary hospital, including patients who underwent open or endovascular vertebral artery revascularization from 2005 to 2022...

We report a unique case of cervical anterior spinal artery (ASA) infarction in a 49-year-old male with hypercholesterolemia and sleep apnea. The patient experienced sudden cervical pain, quadriparesis, areflexia, and urinary incontinence after swallowing a large food bolus. Imaging revealed an infarction at the C3-C5 levels and an anomalous right vertebral artery (VA) originating from the thoracic aorta, tightly enclosed between the aorta and a vertebral column with an anterior osteophyte. This aberrant VA was the primary vascular supply to the ASA, with no contribution from the left VA or supreme intercostal arteries...

BACKGROUND: Vertebral artery injury (VAI) is a known potential complication of posterior cervical fusion surgery. Pre-operative imaging is used to determine the patency of bilateral vertebral arteries during the planning and execution of surgery. This case illustrates an example of a staged anterior/posterior cervical reconstruction in which an iatrogenic VAI combined with a contralateral idiopathic vertebral artery dissection not identified on pre-operative imaging resulted in absent basilar artery anterograde flow...

BACKGROUND: In recent years, there have anecdotal reports of intra-arterial thrombolysis (IAT) for the treatment of spinal cord ischemia (SCI) with encouraging results. We describe a patient with acute cervical SCI who underwent IAT with Tenecteplase at our institution. CASE PRESENTATION: A 20-year-old man presented to the emergency department with a 12-hour history of progressive onset upper and lower extremity numbness, weakness, and urinary incontinence after sustaining a fall...

Understanding the anatomy of the vertebral artery is essential while manipulating the craniovertebral joint during surgery. Its anomalous course in congenital atlantoaxial dislocation makes it more vulnerable to injury. Preoperative dedicated computed tomography (CT) angiography helps identify the artery's position and plan for surgical procedure. A 13-year-boy presented with neck pain and spastic quadriparesis for 1 year. Radiological imaging of the craniovertebral junction revealed atlantoaxial instability with basilar invagination...
