Novel reconstruction of the anterior craniocervical junction using an expandable cage with integrated fixation after total C2 spondylectomy for chordoma

Chordoma is a locally aggressive malignant tumor that generally occurs in the clivus, mobile spine and sacrum. While en bloc resection with wide margins has been advocated as the only cure for chordomas, tumor characteristics and violation of critical anatomical boundaries may preclude pursuing this treatment option in the cervical spine. We present a C2 chordoma in a 35-year-old man with epidural and prevertebral extension that was treated with a single stage anterior–posterior total C2 spondylectomy with novel reconstruction using an expandable cage with integrated fixation followed by stereotactic radiosurgery. Single stage intralesional total C2 spondylectomy via anterior transoral and posterior approaches was performed. The anterior column was reconstructed using an expandable cage with integrated fixation from the clivus to C3. The patient maintained his intact neurological status at 6 month follow-up with full resumption of activities of daily living without any significant morbidity.     

Mechanical thrombectomy for cerebral venous sinus thrombosis employing a novel combination of Angiojet and Penumbra ACE aspiration catheters: the Triaxial Angiojet technique

Cerebral venous sinus thrombosis (CVST) can be life threatening. A previously healthy woman in her early forties on oral contraceptives presented with global CVST and rapid clinical deterioration. A novel ‘Triaxial Angiojet technique’ (KSAW Shuttle [Cook Inc., Bloomington, IN, USA], 5 MAX ACE [Penumbra Inc., Alameda, CA, USA], and Angiojet [Boston Scientific, Marlborough, MA, USA]) was employed to gain access into the superior sagittal sinus. The 5 MAX ACE reperfusion catheter was shortened prior to placing a 4 Fr Angiojet catheter through it. This resulted in markedly improved recanalization with good anterograde flow. The patient was extubated on postoperative day 2 and discharged neurologically intact on postoperative day 10. We report the first case of placing an Angiojet catheter through a larger Penumbra reperfusion catheter when access through a tortuous sigmoid and transverse sinus could not be obtained with a 6 Fr support catheter.     

经口咽入路行环枢融合术对脊髓功能恢复的疗效观察

Objective To present the operative results of 17 patients with atlantoaxial diseases using transoral approach.Methods 17 patients received operation of atlantoaxial fusion using transoral approach.The average age is 27 years old(12～ 47 years).Results All patients had achieved primary healing without any complications.The fusion rate was 100% .The average recovery rate (JOA score system) of myelopathy was 48% .Conclusions Transoral approach was an ideal approach for upper cervical diseases.The infection rate could be lowered down to the minimum if the patients were properly managed perioperatively.Atlantoaxial fusion could be achieved through this approach without instrumentation.

评分法选择PEEP对ARDS病人的临床价值

目的：研究评分法选择PEEP对ARDS病人的临床价值。方法：对1999年～2004年88例ARDS病人随机使用两种方法选择PEEP进行机械通气。其中评分组（实验组）51例，根据评分法四项指标得分数总和，如评分大于等于6分则PEEP用20-25cmHO；3～5分则PEEP用12～20cmH2O；评分小于等于2分则PEEP用5～12cmH2O；传统方法组（对照组）37例，PEEP均使用5～12cmH2O。分别检测两组病例通气开始时、通气后24h时的血气分析，计算两组病例入ICU30d时病死率，观察其并发症发生情况。结果：实验组较对照组痛死率明显下降，具有极显著差异，P〈0．01；且实验组中采用低PEEP小组的病死率亦较对照组低，具有显著差异，P〈0．05。实验组与对照组在通气24h时都能较通气开始时改善病人的血气情况，且实验组较对照组PaO2升高更明显，具有极显著差异，P〈0．001，而pH、PaCO2在两组无显著差异，P〉0．05。两组均未发生气压伤，实验组较对照组并发MOF的发生率低，具有显著差异，P〈0．05；血压明显下降的发生率高，具有显著差异，P〈0．05，但能纠正。结论：采用评分法选择PEEP较传统方法有更高的临床价值，可明显降低削RDS病人痛死率，改善病人的氧合情况，并且并发症较少或可控制。     

超声引导下经会阴部前列腺穿刺活检术的临床应用

目的　探讨超声引导下经会阴部前列腺穿刺活检术临床应用的价值 ,及其与前列腺癌病变之相关因素。方法　回顾性总结了 344例超声引导下经会阴部前列腺穿刺活检的优缺点 ,观察和统计前列腺癌的检出率和发病的相关因素 ,例如 :年龄、 PSA、 PSA密度和前列腺体积。结果　超声引导下经会阴部前列腺穿刺活检的并发症少 ,且没有严重并发症。前列腺癌检出率为 33.72 % ,其检出率与年龄增长密切相关 ,前列腺癌患者血清 PSA和 PSA密度明显高于增生者 ,而前列腺体积不增大。结论　超声引导下经会阴部前列腺穿刺活检因并发症少 ,检出率较高 ,有其自身临床应用的优势。 PSA和 PSA密度是指导穿刺活检的重要指标 ,特别是 PSA>10 ng/ml和 PSAD>0 .15。
