Fluoroscopic percutaneous lumbar zygapophyseal joint cyst rupture: a clinical outcome study

Background contextLumbar zygapophyseal joint (Z-joint) synovial cysts can cause low back pain (LBP), spinal stenosis, and lower extremity radiculopathy. In the literature, there are several minimally invasive techniques described with mixed results. Typical recommended treatment is surgical resection of the cyst. Currently, there is little information available concerning the efficacy and outcome with treatment of Z-joint synovial cyst by percutaneous, fluoroscopic, contrast-enhanced distention, and rupture.PurposeTo evaluate the therapeutic value and safety of Z-joint cyst rupture in symptomatic patients.Study design/settingRetrospective cohort study in an academic outpatient physiatric spine practice.Patient sampleThirty-two patients with moderate-to-severe LBP and leg pain (18 women and 14 men with an age range of 46–86 y; mean age, 66 y) with an average preprocedure symptom duration of 5 months. The patient's clinical symptoms correlated with magnetic resonance imaging studies documenting the presence of a synovial cyst at the corresponding level and side of symptoms. Patients had at least 6 months follow-up (range, 6–24).Outcome measuresNumerical Pain Rating Scale, Roland-Morris Disability Questionnaire, North American Spine Society four-point patient satisfaction survey, recurrence of synovial cyst requiring repeat rupture, and need for surgical intervention.MethodsPatients with symptomatic lumbar Z-joint synovial cyst were identified and their charts were reviewed. Patients included in the study either had symptomatic lumbar LBP or LBP with associated lower extremity radiculopathy. All patients in the study had magnetic resonance imaging's documenting Z-joint synovial cyst that corresponded with the patients' clinical symptoms. All patients received fluoroscopically guided, contrast-enhanced, percutaneous facet cyst distention and rupture followed by an intra-articular facet joint injection of 1 cc kenalog and 1 cc of 1% lidocaine. Seventeen of the patients also received a transforaminal epidural steroid injection just before facet cyst rupture. Telephone follow-up was conducted on all patients.ResultsExcellent long-term (average follow-up 1 y; range, 6–24 mo) pain relief was achieved in 23 (72%) of 32 patients undergoing facet cyst rupture. Twelve patients (37.5%) had synovial cyst recurrence and 11 chose to undergo repeat rupture, which resulted in 5 patients (45%) obtaining complete relief of symptoms and 6 patients (55%) requiring surgical intervention for cyst removal. Fisher exact test demonstrated that all patients who did not have a cyst recurrence were a success and obtained complete relief of symptoms (p<.0002). Patients who underwent a repeat rupture had a 50% chance of a successful outcome. There was no statistical significance between a successful outcome and level of facet cyst rupture, the presence of spondylolisthesis, sex, age, or having a transforaminal epidural steroid injection at the time of the procedure. Wilcoxon signed-rank test demonstrated that the difference in Numerical Pain Rating Scale and Roland-Morris Disability Questionnaire scores before and after the procedure was statistically significant (p<.0001). No complications were reported.ConclusionsFluoroscopic percutaneous Z-joint cyst rupture appears to be a safe and effective minimally invasive treatment option. This procedure should be considered before surgical intervention.

在深静脉血栓—肺栓塞病程中腔静脉滤器的应用价值分析

目的：探讨腔静脉滤器(Vena cava filter VCF)在深静脉血栓(Deep venous thrombosis DVT)—肺栓塞(Pulmonary embolism PE)病程中的应用价值。方法：结合本组25例高危深静脉血栓一肺栓塞患者，对其中24例置放5种构型的永久型或临时型下腔静脉滤器(IVCF)26枚的临床疗效、影响病程与预后因素及病生理改变，复习文献分析讨论。结果：DVT有可能脱落导致PE或致死性肺栓塞；置放IVCF可有效预防肺栓塞，早期进行溶栓治疗，改变预后。结论：严格按适应证植入IVCF，对DVT—PE的早期治疗和预防致死性肺栓塞有重要意义，但其应用价值需进行综合评价和进一步探讨。

α-平滑肌肌动蛋白和β-肌动蛋白在瘢痕组织中的表达

目的 探讨α-平滑肌肌动蛋白(α-SMA)和β-肌动蛋白(β-actin)对增生性瘢痕形成的可能作用。方法 采用荧光定量PCR法检测10例增生性瘢痕和10例正常皮肤组织中α-SMA和β-actin的表达水平。结果 增生性瘢痕组织中α-SMA和β-actin表达水平均高于正常皮肤组织,差异有统计学意义(P<0.01)。结论 α-SMA和β-actin在瘢痕增生中起重要作用;由于β-actin在瘢痕组织和正常皮肤中的不恒定性,建议在瘢痕的mRNA定量研究中不作为内参照物。
