BACKGROUND: Persistent first intersegmental artery (PFIA) is one of the most frequently vertebral artery (VA) variations. The presence of PFIA obviously increases the complexity and difficulty of vertebral lesion treatment. Thus, preoperative detection of PFIA is necessary to increase the successful rate of surgeries. We attempted to evaluate the utility value of three-dimension (3D) computed tomography angiography (CTA) for detecting PFIA in the north Chinese population. MATERIALS AND METHODS: Consecutive patients subjected to CTA between June 2012 and March 2014 were recruited from 5 clinical centers in the north of China...

RATIONALE: The typical intraoperative presentation of vertebral artery injury (VAI) usually involves profuse bleeding and requires immediate treatment. However, an occult VAI may occur intraoperatively and result in delayed life-threatening epidural pseudoaneurysm several days postoperatively. PATIENT CONCERNS: A 21-year-old man with compressive cervical myelopathy resulting from canal stenosis of skeletal fluorosis underwent decompression of C1 to C7 and instrumentation from C2 to C7...

Methods Patients with cerebral artery dissections were reviewed in a hospital setting from 2008 to 2015. Clinical presentations, lesion locations, treatment modalities, functional outcomes, and mortality were reviewed. Parent artery occlusion was the first choice for surgery or endovascular treatment of a hemorrhagic dissecting cerebral artery. Endovascular or surgical reconstructive treatment was indicated in patients whose parent artery could not be occluded. Favorable functional outcomes were determined using modified Rankin Scale (mRS) scores of 0-2...

Subclavian artery aneurysms are rare and even more uncommon in patients with fibromuscular dysplasia. A 20-year-old man with a past medical history of moyamoya disease, presented with an abnormal mass shadow in the apex of the right lung on chest x-ray. Based on computed tomography imaging, a diagnosis of right subclavian artery aneurysm was established and an excision of the aneurysm was performed. Since the left vertebral artery is dominant, the proximal and distal right subclavian artery and right vertebral artery were clamped...

Background: Although vertebral artery (VA) dissecting aneurysms are treated by direct or endovascular surgery, some disadvantages are associated with each surgery. Therefore, the type of surgery should be selected based on the condition of the aneurysm. We performed aneurysm trapping by endovascular surgery via the contralateral VA after proximal direct ligation with bypass to prevent complications as well as achieve complete treatment. Case Description: We attempted to insert a distal clip to achieve complete trapping of the ruptured VA dissecting aneurysm after proximal ligation with occipital artery-posterior inferior cerebellar artery (PICA) anastomosis; however, the operative field was limited by the existence of lower cranial nerves, brain swelling, and tortuosity of VA...

Background: Giant aneurysms (>25 mm) arising from the vertebral artery (VA) often present with slow progression of symptoms and signs because of gradual brainstem and cranial nerve compression. The underlying pathophysiology is not well understood, and treatment, wherever possible, is tailored to each singular case. Endovascular management does not usually solve the problem of mass compression, whereas surgical treatment involves several complications. Case Description: A 58-year-old woman presented with a continuously growing giant right VA aneurysm, partially thrombosed, even after endovascular treatment (placement of two diversion flow stents)...

Introduction: Kimmerle anomaly is the bony ridge between the lateral mass of atlas and its posterior arch or transverse process. This bony tunnel may include the V3 segment of the vertebral artery, vertebral vein, posterior branch of the C1 spinal nerve, and the sympathetic nerves, which results in the clinical symptoms of this disease. Reports on the surgical treatment of Kimmerle anomaly are rare. There are no reports on minimally invasive surgical treatment of this pathology. Materials and Methods: Six patients with Kimmerle anomaly were treated from 2015 until 2016...

Background: Spinal instrumentation using rods and screws have become procedure of choice for posterior fixation. Vertebral artery anatomy is highly variable in this region posing challenges during surgery. Our study used 3D printer model to understand the anatomy and variations in vertebral artery in live patients thereby providing an accurate idea about vertebral artery injury risk in these patients preoperatively and to rehearse the whole procedure. Methods: Ten patients of developmental craniovertebral junction (CVJ) anomalies who were planned for operative intervention in the Department of Neurosurgery at SMS Hospital from February 2016 to December 2016 were analysed using a 3D printer model...

BACKGROUND AND IMPORTANCE: Hemangiopericytoma is a rare vascular tumor with central nervous system involvement representing only 1% of central nervous system tumors. They rarely affect the vertebral column. Complete surgical resection is the treatment of choice for hemangiopericytoma given their high rates of local recurrence. However, the high vascularity of such tumors with the risk of massive bleeding during surgery represents a significant challenge to surgeons. Therefore, preoperative endovascular embolization via the transarterial route has been advocated...

INTRODUCTION: Recently, trauma management has been markedly improved with interventional radiology (IVR) and damage-control strategies. However, the indications for its use in hemodynamically unstable patients with severe trauma remains unclear. In some cases, IVR may be more effective than surgery for damage-control hemostasis; however, performing IVR in life-threatening trauma settings is challenging. To address this, we practiced and evaluated a trauma-management system with emergency physicians who trained for both severe trauma management, and techniques of surgery and IVR...
