The spine is the most common site of bone metastases from malignant tumors, with metastatic epidural spinal cord compression occurring in about 10% of patients with spinal metastases. Palliative radiotherapy and simple laminectomy and decompression have been the main treatments for metastatic spinal cord compression. The former is ineffective and delayed for radiation-insensitive tumors, and the latter often impairs spinal stability. With the continuous improvement of surgical techniques and instrumentation in recent years, the treatment model of spinal metastases has changed a lot. Decompression surgery underwent open decompression, separation surgery, minimally invasive surgery and laser interintermal thermal ablation decompression. However, no matter what kind of surgical plan is adopted, it should be assessed precisely according to the specific situation of the patient to minimize the risk of surgery as far as possible to ensure the smooth follow-up radiotherapy. This paper reviews the research progress of decompression for spinal metastases.

Aortic pseudoaneurysm after cardiac surgery is a rare entity, but it is potentially fatal due to its clinical course along with higher morbidity and mortality rates. Instead of open surgical repair, percutaneous procedures have been introduced as other options for managing an aortic pseudoaneurysm. In this case report, we describe transesophageal echocardiography guidance for successful percutaneous closure of an aortic pseudoaneurysm located in the left ventricular outflow tract by using a type II Amplatzer vascular plug in a patient in whom open surgical repair was not recommended.

A case is presented of acute spinal cord compression by a thoracic dumbbell spinal schwannoma in a young woman with neurofibromatosis type 1 (NF-1). A successful outcome was achieved with total excision of the lesion and decompression of the spinal cord. Greater recognition of the reversibility of spinal cord compression in the developing world is necessary to reduce major permanent morbidity.

We report a very rare case of cervical compressive myelopathy by an anomalous bilateral vertebral artery (VA) entering the spinal canal at the C1 level and compressing the spinal cord. A 70-year-old woman had been suffering from progressive gait disturbance. Magnetic resonance imaging revealed that a bilateral VA at the V4 segment had abnormal courses and caused compression to the high cervical cord. VA repositioning was performed by anchoring a suture between the artery and around the arachnoid membrane and dentate ligament, and then, microvascular decompression using a Teflon sponge was done between the VA and the spinal cord. The weakness in the patient improved in the lower extremity after the operation. Anomalous VA could be one of the rare causes of cervical compressive myelopathy. Additionally, an anchoring suture and microvascular decompression around the VA could be a sufficient and safe method to indirectly decompress the spinal canal.

OBJECTIVETo explore the efficacy of one stage or staging treatment of cervical spondylotic myelopathy through combined posterior and anterior approaches.
METHODSFrom June 2001 to October 2008, 45 patients with pinching cervical spondylotic myelopathy and developmental stenosis of cervical spinal canal were decompressed through combined posterior and anterior approaches in one stage or staging operation. Among the patients, 35 patients were male and 10 patients were female, ranging in age from 45 to 72 years, with an average of 53 years. Five patients were decompressed through combined posterior and anterior approaches in one-stage operation, and other 40 patients were treated in staging operation. All the patients were treated with open-door posterior cervical expansive laminoplasty and anterior decompression, bone graft and titanium plate internal fixation. JOA scores were used to evaluate the therapeutic effects at the 3rd month and one year after operation.
RESULTSAfter the treatment, 44 patients were followed up from 13 to 62 months, with an average of 30 months. One patient was dead of lung infection at the 21th day after operation. The nerve root palsy of C5 was found in 3 cases. One patient had postoperative hoarseness. Axial symptoms were found in 14 cases. Two patients had donor site complications. There were no screws broken or back out, no screw loosening, no moving or sinking of bone block or Ti-net, no door re-closer and cervical deformity. Forty-four patients got spinal fusion. According to JOA score criteria: the average preoperative JOA score was (9.36 +/- 2.24) points, JOA score was (12.34 +/- 2.64) points in 3 months after operation, (12.77 +/- 2.61) points in one year after operation. Among 44 cases, 16 got an excellent result, 19 good, 6 fair, 3 invalid. There were statistically differences between preoperative score and 3 months or one year after operation.
CONCLUSIONDecompression through combined posterior and anterior approaches for the treatment of pinching cervical spondyoltic myelopathy and developmental stenosis of cervical spinal canal has good efficacy, as well as a safety operation method. The operation method with one or staging decompression through combined anterior and posterior approach should be chosen according to the conditions of the patients and the operations. Anterior decompression, bone graft and titanium plate internal fixation could restore the height of vertebral body effectively and prevent fusion complication.

OBJECTIVETo analyze the correlations between increased spinal cord signal intensity on magnetic resonance images (MRI) and the clinical prognosis of compressive cervical myelopathy.
METHODSSixty-six patients with cervical spondylotic myelopathy underwent surgeries through the anterior approach. In all the patients, the diagnoses were established on the basis of both neurological examination and MRI findings that showed spinal cord compression. The patients were divided into two groups according to preoperative MRI, namely isointense MRI T1/T2 signal group and iso/hyperintense MRI T1/T2 group. The JOA scores of the patients were evaluated before and at 6 and 12 months after the operation.
RESULTSThe patients were followed up for 12 to 38 months after the operation (mean 21 months), and no statistically significant difference were found in the pre- and postoperative JOA scores between the two groups (P>0.05).
CONCLUSIONThe peoperative hyperintense signals on T2 weighted MRI does not correlate to the prognosis of patients with compressive cervical myelopathy, who may also have favorable clinical outcomes after the operation.

OBJECTIVE:
To evaluate the therapeutical effect of surgical treatment for thoracic angioma with extraosseous extension which causes spinal cord compression and neurological dysfunction.
METHODS:
We retrospectively analyzed 5 cases of thoracic vertebral body angioma with extraosseous extension and spinal cord compression. The operation were performed through anterior approach to resect the involved vertebral body and intracanal angioma in 5 patients. Bone graft and internal fixation were also completed in the meantime. Two patients accepted radiotherapy for 2 periods of treatment postoperatively, and the other 3 patients didn't accept the other supportive therapy.
RESULTS:
The blood loss during the operation was 1000 mL to 1500 mL. All the patients recovered their neurological function rapidly after the operation. The patients were followed up for 1 to 4 years, and no patient recurred. The bone graft was solidly fused in all patients. No hardware failure occurred.
CONCLUSION
The surgical treatment for thoracic vertebral body and extraosseous angioma with spinal cord compression is effective, reliable, and workable. Good long-term result can be obtained.

OBJECTIVETo study the relationship between cervical pedicle and compressed spinal cord.
METHODSOne hundred and five patients (53 male,52 female,age from 29 to 80 years) with cervical spondylotic myelopathy who needed surgery were included from December 2011 to January 2013 in Shengjing Hospital. Plain MRI scan was used for cross section of C4 - C7 vertebral bodies parallel to the axis of bilateral pedicle, and the images were sent to the workstation. PACS system was applied to measure the anatomical parameters related to the security of cervical pedicle screw, including the shortest distance from medial left/right cervical pedicle to the cervical spinal cord (LH/RH), and the smallest angle between the longitudinal axis of left/right cervical pedicle and the screw which was assumed to just touch the cervical spinal cord (LSA/RSA). All these data in each segment were classified according to compression or not:with compression and without compression. Twelve cases were selected and measured by MRI and 3D cervical CT for spinal canal width D, namely the straight-line distance between the medial margins of cervical pedicle. And the results of two methods were compared to see whether there were statistical differences.
RESULTSAt C4, LH was (7.2±1.3) mm, RH was (6.7±1.4) mm, and the average was (6.9±1.4) mm; at C5, LH was (7.7±1.4) mm, RH was (6.7±1.4) mm, and the average was (7.2±1.5) mm; at C6, LH was (8.2±1.5) mm, RH was (6.9±1.3) mm, and the average was (7.5±1.5) mm; at C7, LH was (8.2±1.4) mm, RH was (7.3±2.1) mm, and the average was (7.7±1.8) mm. At C4, LSA was 34.4°±4.2°, RSA was 34.4°±5.2° and the average angle was 34.4°±4.7°; at C5, LSA was 35.9°±5.2°, RSA was 34.6°±5.4° and the average angle was 35.3°±5.3°; at C6, LSA was 37.4°±4.8°, RSA was 34.8°±4.8° and the average angle was 36.1°±5.0°; at C7, LSA was 39.2°±5.8°, RSA was 37.1°±5.2° and the average angle was 38.1°±5.6°; There were no statistically significant differences between segments with and without compression in H, SA and D (all P>0.05).
CONCLUSIONSThere is security space between the medial vertebral pedicle and compressed spinal cord. There is individual variation in security space. It is very necessary to identify security space before surgery by MRI, emphasize individual procedure and avoid spinal cord injury.

The authors describe a case of an 80-year-old man with a gradual weakness of the lower extremities not linked to any known traumatic episode over the 2 weeks before admission. CT scan and MRI of the spine revealed a cystic formation, measuring about 1cm in diameter, at C7-T1 at the left posterolateral site at the level of the articular facet. During surgery, the mass appeared to be in the ligamentum flavum at the level of the articular facet and was in contact with the dura mater. After the removal of the mass, there was an immediate and significant improvement of the patient's symptoms. Histopathologic examination showed the cyst to be composed of nonspecific degenerative fibrous tissue with mild inflammatory change and confirmed the cyst as a synovial cyst. Synovial cyst in the cervical region is a very rare lesion causing myelopathy. Surgical removal of the cyst and decompression of the spinal cord results in good neurological recovery.
