Spinal Hydatid Cyst Disease : Challenging Surgery - an Institutional Experience

OBJECTIVE: Hydatid cyst disease is caused by the parasite Echinococcus granulosus. It is rarely seen in the vertebral system, occurring at a rate of 0.2–1%. The aim of this study is to present 12 spinal hydatid cyst cases, and propose a new type of drainage of the cyst.METHODS: Twelve cases of spinal hydatid cysts, surgical operations, multiple operations, chronic recurrences, and spinal hydatic cyst excision methods are discussed in the context of the literature. Patients are operated between 2005 and 2016. All the patients are kept under routine follow up. Patient demographic data and clinicopathologic characteristics are examined.RESULTS: Six male and six female patients with a median age of 38.6 at the time of surgery were included in the study. Spinal cyst hydatid infection sites were one odontoid, one cervical, five thoracic, two lumbar, and three sacral. In all cases, surgery was performed, with the aim of total excision of the cyst, decompression of the spinal cord, and if necessary, stabilization of the spinal column. Mean follow up was 61.3 months (10–156). All the patients were prescribed Albendazole. Three patients had secondary hydatid cyst infection (one lung and two hepatic).CONCLUSION: The two-way drainage catheter placed inside a cyst provides post-operative chlorhexidine washing inside the cavity. Although a spinal hydatid cyst is a benign pathology and seen rarely, it is extremely difficult to achieve a real cure for patients with this disease. Treatment modalities should be aggressive and include total excision of cyst without rupture, decompression of spinal cord, flushing of the area with scolicidal drugs, and ensuring spinal stabilization. After the operation the patients should be kept under routine follow up. Radiological and clinical examinations are useful in spotting a recurrence.

Comparative Analysis of Vertebroplasty and Kyphoplasty for Osteoporotic Vertebral Compression Fractures

STUDY DESIGN: A retrospective study. PURPOSE: The aim of this study is to compare the efficacy and outcome of vertebroplasty compared with unipedicular and bipedicular kyphoplasty for the treatment of osteoporotic vertebral compression fractures in terms of pain, functional capacity and height restoration rates. OVERVIEW OF LITERATURE: The vertebroplasty procedure was first performed in 1984 for the treatment of a hemangioma at the C2 vertebra. Kyphoplasty was first performed in 1998 and includes vertebral height restoration in addition to using inflation balloons and high-viscosity cement. Both are efficacious, safe and long-lasting procedures. However, controversy still exists about pain relief, improvement in functional capacity, quality of life and height restoration the superiority of these procedures and assessment of appropriate and specific indications of one over the other remains undefined. METHODS: Between 2004 and 2011, 296 patients suffering from osteoporotic vertebral compression fracture underwent 433 vertebroplasty and kyphoplasty procedures. Visual analogue scale (VAS), the Oswestry Disability Index (ODI) and height restoration rates were used to evaluate the results. RESULTS: Mean height restoration rate was 24.16%+/-1.27% in the vertebroplasty group, 24.25%+/-1.28% in the unipedicular kyphoplasty group and 37.05%+/-1.21% in the bipedicular kyphoplasty group. VAS and ODI scores improved all of the groups. CONCLUSIONS: Vertebroplasty and kyphoplasty are both effective in providing pain relief and improvement in functional capacity and quality of life after the procedure, but the bipedicular kyphoplasty procedure has a further advantage in terms of height restoration when compared to unipedicular kyphoplasty and vertebroplasty procedures.

Schwannoma of the conus medullaris: a rare case / 癌症

Intradural schwannoma of the conus medullaris is a rare form of spinal neoplasm, which commonly occurs in the lumbar region. Conus medullaris level is unusual for schwannomas. A 49-year-old woman presented with chronic sciatica, mild bladder dysfunction, and paresthesia in the buttocks. Magnetic resonance imaging of the spine showed a mass lesion in the conus medullaris region with nerve compression. The tumor was completely resected and diagnosed histologically as schwannoma. The patient recovered after surgery. Clinical and radiologic features of this rare tumor are reviewed and are accompanied by literature findings.

Effect of iloprost on adrenal medullary grafts in central nervous system transplantation and apoptosis

To investigate whether iloprost, a stable analog of prostacyclin, is useful for the preservation of neural grafts in transplantation surgery. This study was conducted at the Microsurgery Laboratory of the Department of Neurosurgery, Faculty of Medicine, Ankara University, Ankara, Turkey in 2003. The animals [rabbits] were divided into 3 groups. In group I, autografts taken from the adrenal medulla were stored in 0.9% sodium chloride [NaCl] solution for 45 minutes before transplantation. In group II, autografts taken from the adrenal medulla were stored in iloprost solution [50 ng/ml] for 45 minutes before transplantation. Graft transplantation was not performed in the third group. In group I, the grafts partially preserved their viability. In group II, the large adrenal medullary cells had evident euchromatin nuclei fused with neurons, and there was an increase in vascularization. Three weeks after transplantation surgery, it was determined that iloprost maintained the viability of the graft tissue and probably prevented apoptosis, and facilitated the integration of the graft tissue into the host brain
