BACKGROUND: There are few studies reporting the use of atlantoaxial pedicle screws and the long-term effects of C1-C2 posterior fusion in children. Our study is to investigate the initial results of C1-C2 pedicle screw fixation for pediatric atlantoaxial dislocation (AAD) and assessed spontaneous change of postoperative radiography after a long-term follow-up period. METHODS: Posterior pedicle screw fixations were performed in 21 pediatric patients with AAD. All the patients underwent implant removal 1 year after their initial surgery and had regular follow-up with an average duration of 76...

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...

We report the case of a young woman who experienced ischemia of upper limb after osteopathic manipulation. Duplex and CT scan showed wall hematoma of the ostium of subclavian artery. The patient spontaneously recovered so that no surgery was necessary. Dissection of vertebral and carotid arteries has been reported after osteopathic manipulations. We report ischaemia of upper limb secondary to dissection of subclavian artery. Arterial dissections associated with manipulation should be recorded in a register in order to assess more carefully the vascular risk that this method carries...

Although the anatomy of the posterior inferior cerebellar artery (PICA) is highly variable, a solitary PICA supplying both hemispheres of the cerebellum is rare. A 76-year-old woman presented with severe headache and subsequent loss of consciousness and was admitted to our hospital. Initial computed tomography showed subarachnoid hemorrhage. Three-dimensional digital subtraction angiography revealed a saccular aneurysm arising from the right vertebral artery (VA)-PICA bifurcation. The PICA branching from the right VA was enlarged, tortuous, and crossed the midline to supply both cerebellar hemispheres...

BACKGROUND: Hybrid operation combining endovascular and open surgery procedure is supposed to achieve the recanalization for post-stenting long-segmental occlusion of VA ostium simultaneously. CASE DESCRIPTION: One patient with post-stenting long-segmental occlusion in VA ostium was reported. His symptoms could not be relieved by medical therapy. Recanalization combining endovascular and open surgery procedure simultaneously was performed. The hybrid recanalization was success and the patient demonstrated with no symptoms attacked during the follow-up...

Chordoma arising from the cervical spine is rare and the traditional long-term prognosis is typically poor. Total en bloc spondylectomy with a wide margin is generally accepted to be the most appropriate management for thoracic and lumbar malignant tumors. However, this method is still challenging for the cervical spine because of the proximity of the tumor to the vertebral arteries and neural elements. Here, we report a 73-year-old man with a C5 vertebral chordoma treated with total piecemeal spondylectomy...

A 13-year-old boy with a spontaneous vertebrobasilar artery dissecting aneurysm (VADA) in the extracranial artery, which was only 1 mm away from the initial segment of subclavian artery, was successfully treated with a covered-stent to block the artery of the VADA. Our experience indicates that this is a fast, reliable, effective and economical technique, particularly suitable for surgeries in settings with limited resources.

Surgery for the Cranio-vertebral (CV) junction anomalies using top loading subocciput (C0)/C1-C2 screws is difficult and requires high level of skill and expertise. This is because of complex abnormal anatomy in that region and other issues including the instrumentation. Thorough knowledge of the 3D anatomy of the Craniovertebral junction of the patient is essential for favourable outcome. The customised 3D printed model of CV junction region of the patient can be used for studying the anatomy and relationship of vertebral artery to the C1-C2 joint before the actual surgery...

BACKGROUND: Anomalies of vertebral arteries are rare, and usually detected incidentally. However, very rarely, they can manifest clinical symptoms. We describe such a symptomatic case of high cervical spinal cord compression associated with persistent C2 segmental arteries. CASE DESCRIPTION: A 67-year-old man presented with a 5-year history of worsening left-sided weakness and gait disturbance. Magnetic resonance imaging, 3D-computed tomography and digital subtraction angiography revealed anomalous courses of vertebral arteries, compressing the cervical spinal cord at C1 level from both sides...

The article describes a case of one-stage surgical treatment of a patient with progressive chronic cerebral ischemia caused by combined steno-occlusive lesions of the carotid and vertebral arteries. The disease was complicated by intolerance to temporary occlusion of the carotid artery due to an incomplete circle of Willis. We performed extra-anatomic carotid-vertebral artery bypass with subsequent ipsilateral carotid endarterectomy. A temporary intraluminal shunt was used at the main stage of reconstructive surgery...

The VACTERL association, co-occurrence of vertebral, anorectal, cardiac, tracheoesophageal, genitourinary, and limb malformations, is a rare congenital anomaly. Several cardiac anomalies have been reported as a part of the VACTERL association, particularly ventricular and atrial septal defects. Pulmonary artery sling is a rare congenital abnormality in which the left pulmonary artery arises from the right pulmonary artery. This anomaly is not frequently observed in the VACTERL association and has been rarely reported...

BACKGROUND: Extreme lateral interbody fusion (XLIF) has rapidly become a popular operative procedure for lumbar canal stenosis and scoliosis. This approach provides direct access to the lateral aspect of the disc with minimal disruption of spinal structures, including ligaments and muscles. However, it involves risk of injuries to the lumbar nerve plexus, segmental artery and intestinal tract because of the limited surgical field. This study aimed to clarify the benefit of using a microendoscope to prevent these injuries...

An 83-year-old man presented 4 years after right carotid endarterectomy (CEA) with an infection of his prosthetic Dacron patch. Initial scans (CT angiogram and whole body labelled white cell scan) were clear with no infection or collection noted. Systemically, the patient presented well with no recorded fevers. With an occluded left internal carotid artery and severely stenosed vertebral arteries, surgery presented a high risk of major stroke due to the lack collateral supply and this was discussed extensively...

We herein present a case of distal aortic arch aneurysm with an isolated left vertebral artery(LVA). In surgery, after establishing cardiopulmonary bypass, the LVA was anastomosed to the left common carotid artery (LCCA) while under moderate hypothermia. Selective cerebral perfusion (SCP) was then initiated by inserting catheters into the brachiocephalic artery( BCA), the LCCA and the left subclavian artery (LSA). The aorta was transected between the BCA and the LCCA, and an open stent graft was deployed into the descending aorta during circulatory arrest...

The treatment of intracranial complicated aneurysms remains challenging. In patients with complicated aneurysms that are neither clippable nor coilable, flow alteration treatment (FAT) with a combined procedure of proximal/distal occlusion or trapping of an aneurysm with bypass surgery has been reported. However, it is difficult to predict whatever FAT can achieve aneurysmal obliteration without ischemic complications. A 69-year-old female was incidentally diagnosed with a left vertebral artery (VA) fusiform aneurysm distal to the left posterior inferior cerebellar artery (PICA)...

INTRODUCTION: The aim of this study was to explore the predisposing factors for fracture nonunion after a lateral screw was combined with C2 pedicle/laminar screw for a type II odontoid fracture and hopefully provide references in decision making and surgical planning for spinal surgeons. METHODS: This is a retrospective study. By retrieving the medical records from January 2010 to July 2015 in our hospital, 117 type II odontoid fracture patients were reviewed. According to the occurrence of fracture union at the final follow-up, patients were divided into 2 groups: union and nonunion...

BACKGROUND: Posterior inferior cerebellar artery (PICA) aneurysms represent a challenging pathology. PICA sacrifice is often necessary, due to the high proportion of nonsaccular aneurysms that can be found in this location. Several treatments are available, but the infrequency of these aneurysms and the increasing number of endovascular techniques have limited the development of a standardized algorithm for cases in which open surgery is indicated. OBJECTIVE: We present our series of nonsaccular PICA aneurysms, in the attempt to define an algorithm for their surgical management...

Variations of V3 and V4 segments of Vertebral Artery (VA) are very rare. We report an extremely rare case of hypoplastic and duplicated V4 segment of right VA along with variant origin of right Anterior Inferior Cerebellar artery (AICA) from right Posterior Inferior Cerebellar artery (PICA). AICA was duplicated, with one vessel arising from PICA and another arising from distal Hypoplastic Vertebral Artery (HVA). HVA should be considered for the diagnosis of acute stroke of brainstem and cerebellum. Knowledge about VA variations is important to prevent iatrogenic injuries during surgeries involving posterior cranial fossa...
