Abstract
Background Limited information is available on mid-term results and quality of life (QOL) after endovascular sclerotherapy of venous malformations. Purpose To compare two agents-polidocanol and ethanol-with a focus on the influence on QOL after sclerotherapy. Material and Methods Forty-one consecutive patients with a venous malformation in the head and neck area or in the extremities were treated with polidocanol between 2008 and 2013. Pre- and post-treatment magnetic resonance imaging (MRI) scans were compared. All patients completed a self-evaluation form on symptoms as well as a QOL questionnaire. The results were compared with previously obtained material during 1991-2001, comprising 44 consecutive, similarly located venous malformation patients subject to ethanol sclerotherapy. Results No significant clinical complications were observed. Subjectively, 19 (46%) of the patients benefitted from the treatment. QOL results showed that 85% of patients had an index < 39 – where 0 represents the highest and 100 the lowest QOL. Patients in the ethanol group had marginally better overall post-treatment QOL results. Post-treatment MRI in 35 patients showed the size of the malformation unchanged in 19 (54%) patients, in ten (29%) there was a decrease (<50%) while in six (17%) the decrease was more significant (>50%). Post-treatment MRI results did not correlate with either subjective symptoms or QOL results. Conclusion Polidocanol sclerotherapy were found to be an effective, safe, and well tolerated treatment option for low flow venous malformations. Routine MRI for follow-up appears redundant and may be omitted.

Analysis of risk factors causing short-term cement leakages and long-term complications after percutaneous kyphoplasty for osteoporotic vertebral compression fractures

By London Spine

Background Percutaneous kyphoplasty (PKP) is a common treatment modality for painful osteoporotic vertebral compression fractures (OVCFs). Pre- and postoperative identification of risk factors for cement leakage and follow-up complications would therefore be helpful but has not been systematically investigated. Purpose To evaluate pre- and postoperative risk factors for the occurrence of short-term cement leakages and long-term complications after PKP for OVCFs. Material and Methods A total of 283 vertebrae with PKP in 239 patients were investigated. Possible risk factors causing cement leakage and complications during follow-up periods were retrospectively assessed using multivariate analysis. Cement leakage in general, three fundamental leakage types, and complications during follow-up period were directly identified through postoperative computed tomography (CT). Results Generally, the presence of cortical disruption ( P = 0.001), large volume of cement ( P = 0.012), and low bone mineral density (BMD) ( P = 0.002) were three strong predictors for cement leakage. While the presence of intravertebral cleft and Schmorl nodes ( P = 0.045 and 0.025, respectively) were respectively identified as additional risk factors for paravertebral and intradiscal subtype of cortical (C-type) leakages. In terms of follow-up complications, occurrence of cortical leakage was a strong risk factor both for new VCFs ( P = 0.043) and for recompression ( P = 0.004). Conclusion The presence of cortical disruption, large volume of cement, and low BMD of treated level are general but strong predictors for cement leakage. The presence of intravertebral cleft and Schmorl nodes are additional risk factors for cortical leakage. During follow-up, the occurrence of C-type leakage is a strong risk factor, for both new VCFs and recompression
