RESUMO
Although both internal iliac arteries were saved during operation, the patient developed paraplegia immediately after aortoiliac reconstruction due to the spinal cord ischemia. We report a successfully treated immediate postoperative paraplegia by performing second operation and creating bypass from the bifurcated Dacron graft to the previously detected nonpaired huge lumbar artery.

Percutaneous vertebroplasty is used to manage osteoporotic vertebral body compression fractures. Although it is relatively safe, complications after vertebroplasty ranging from minor to devastatingly major ones have been described. Cement leakage into the spinal canal is one such complication. Subacute progressive ascending myelopathy is an infrequent neurologic complication after spinal cord injury, typically presenting as ascending neurologic deficit within weeks after the initial insult. The precise cause of subacute progressive ascending myelopathy still remains an enigma, considering the rarity of this disorder. The authors present the case of a 62-yr-old woman with osteoporotic vertebral fracture who underwent percutaneous vertebroplasty and developed T6 complete paraplegia because of cement leakage. A few weeks later, the neurologic level ascended to higher cervical level (C3). To date, no case of subacute progressive ascending myelopathy secondary to cement leakage after percutaneous vertebroplasty has been reported. Literature is reviewed regarding subacute progressive ascending myelopathy, and the rehabilitation challenges in the management of this patient are discussed.

Morquio syndrome, or mucopolysaccharidosis type IV, is a rare enzyme deficiency disorder and results in skeletal dysplasia. Odontoid dysplasia is common among affected patients, resulting in atlantoaxial instability and spinal cord compression. Surgical treatments include decompression and prophylactic fusion, during which intraoperative neuromonitoring is important to alert the surgical team to changes in cord function so that they can prevent or mitigate spinal cord injury. This report describes a 16-year-old girl with Morquio syndrome who developed paraplegia due to thoracic spinal cord infarction during foramen magnum and atlantal decompression. This tragic event demonstrates the following: 1) that patients with Morquio syndrome are at risk for ischemic spinal cord injury at levels remote from areas of maximal anatomical compression while under anesthesia in the prone position, possibly due to impaired cardiac output; 2) the significance of absent motor evoked potential responses in the lower limbs with preserved upper-limb responses in an ambulatory patient; 3) the importance of establishing intraoperative neuromonitoring baseline assessments prior to turning patients to the prone position following induction of anesthesia; and 4) the importance of monitoring cardiac output during prone positioning in patients with chest wall deformity.

STUDY DESIGN: Experimental. OBJECTIVE: To determine the effects of a porous tube transplant in spinal cord transected rats. SETTING: Acadia University, Wolfville, Nova Scotia, Canada. METHODS: Female rats were randomly assigned to three experimental groups: control (Con, n=8), spinal cord transected (Tx, n=5) and spinal cord transected with transplant (TxTp, n=7). The rats in the TxTp and Tx groups received a complete spinal cord transection at the T10 level and the TxTp group immediately received a porous tube transplant. RESULTS: Locomotor activity rated on the Basso, Beattie, Bresnahan scale improved significantly in the TxTp animals over the 4 weeks such that final scores were 21, 1.4 and 7.1 for the Con, Tx and TxTp groups, respectively. As expected, the muscle to body mass ratios of the hindlimb skeletal muscles of the Tx group were decreased (soleus 35%, plantaris 29% and gastrocnemius 29%) and this was also observed in the TxTp group (soleus 33%, plantaris 23% and gastrocnemius 30%). Cytochrome c oxidase (CYTOX) activity in the plantaris was decreased by Tx but maintained in the TxTp group (Con=82.2, Tx=44.8 and TxTp=72.8 U/min/g). CONCLUSION: Four weeks after the spinal cord transection, plantaris CYTOX activity and locomotor function improved with porous tube implantation.
