Percutaneous coronary intervention in two occluded arms of a saphenous 'Y'-graft: the importance of protecting both of your arms.

Percutaneous intervention in saphenous vein grafts (SVG) carries a higher risk of distal embolization than intervention in a native vessel, and use of a distal protection device has been shown to improve the outcomes in SVG interventions. We describe an intervention done in an unexpected 'Y' SVG which required dual distal protection with Filterwires placed in both limbs of the diseased graft and which was performed via a 6 Fr guide catheter.     

同种异体骨支撑架微创治疗股骨头坏死的临床研究

目的应用改良髓芯减压术结合同种异体骨支撑架加自体骨和脱钙骨基质（decalcified bone matrix，DBM）治疗早期股骨头坏死，探索早期股骨头坏死的微创治疗方法。方法2004年1月～2005年4月，23例24个髋关节采用经大转子下通过股骨颈钻隧道至股骨头骨坏死区，将装有自体松质骨和DBM的同种异体骨支撑架经隧道拧入骨坏死区直至软骨下骨约5mm处，隧道远端用自体髂骨填塞。观察手术前后Harris评分变化、x线影像学表现及是否需进一步治疗。结果本组所有患者均获得随访，平均随访19（12—27）个月，以最后一次随访资料作为最终评价依据。Harris评分，术前优良率为43．5％（10／23）。术后优良率为91．3％（21／23）。22侧髋关节影像学表现保持稳定，无明显并发症发生。结论同种异体骨支撑架植入结合自体松质骨和DBM治疗成人股骨头坏死，增加了股骨头负重区软骨下骨的机械支撑，成骨作用强，有利于股骨头坏死的修复与重建，同时，不破坏患者股骨头本身的血液供应，创伤小，操作简单，值得临床推广使用。     

两种微创方法治疗股骨颈骨折的临床对照试验

目的分别应用三针锁针加压器外固定和空心拉力钉内固定疗法治疗股骨颈骨折,探讨股骨颈骨折最佳治疗方法.方法应用三针锁针加压器外固定治疗股骨颈骨折63例,其中男24例,女39例;年龄55～89岁,平均(64.5±3.2)岁;Garderl Ⅰ型2例,Ⅱ型15例,Ⅲ型38例,Ⅳ型8例.应用空心拉力钉内固定治疗63例,其中男29例,女34例;年龄45～76岁,平均(62.2±2.9)岁;Garden Ⅰ型4例,Ⅱ型24例,Ⅲ型28例,Ⅳ型7例.对其疗效进行分析.结果126例除2例死亡外均得到随访.115例愈合,其中10例股骨头坏死.外固定组愈合58例,股骨头坏死4例,死亡1例;内固定组愈合57例,股骨头坏死6例,死亡1例.根据Harris功能评定标准评价疗效,外固定组62例中优24例,良26例,可8例,差4例,优良率80.65%;内固定组62例中优23例,良27例,可6例,差6例,优良率80.65%.Harris评分外固定组平均(80.40±1.21)分,内固定组平均(79.14±1.47)分,两组Harris评分比较差异无统计学意义(P＞0.05).结论采用内外固定治疗股骨颈骨折疗效无明显差异,但外固定创伤小、费用低、可早期离床;而采用拉力钉内固定器医疗成本高,卧病时间相对较长,且需二次手术取内固定钉.     

腹腔镜辅助子宫肌瘤剔除术30例手术体会

目的：观察腹腔镜辅助子宫肌瘤剔除术的疗效,探讨腹腔镜辅助子宫肌瘤剔除术的可行性。方法：回顾性分析我院2008年全年30例子宫肌瘤患者的手术方法及手术结果。结果：30例患者全部治愈,平均手术时间78min,术后患者指征数据佳。结论：腹腔镜辅助子宫肌瘤剔除术综合了经典开腹及微创手术的优点,可以提倡。     

Planning for minimally invasive unicompartmental knee arthroplasty

Unicompartmental knee arthroplasty (UKA) is considered the treatment of choice in patients with single compartment arthritis of the knee at early stages or with osteonecrosis limited to one compartment. However, results in the literature are still controversial and it is a technically difficult procedure. The main goal of UKA is to restore the articular space of the afflicted compartment, without influencing the limb alignment. Selection of patients and pre-operative planning are crucial. The necessity to improve functional results and to reduce immobilization of the patients has led to the development of minimally invasive surgery. Applied to UKA, this approach reduces blood loss and surgical time, causes fewer symptomatic postoperative complications, and permits earlier recovery compared to the traditional incision. The shorter incision makes careful pre-operative planning essential. We briefly review the indications for UKA, the pre-operative clinical and radiological assessment, and the surgical procedure.

输尿管上段结石的微创手术治疗

目的：探讨输尿管上段结石的治疗方法。方法：回顾性分析输尿管镜下气压弹道碎石(URSL），后腹腔镜输尿管切开取石(RLU)、经皮肾穿刺取石(PCNL)治疗输尿管上段结石患者的临床资料。其中URSL组25例，RLU组20例。PCNL组9例。结果：URSL组碎石成功18例；7例不成功，其中3例改为开放手术，1例改为后腹腔镜取石。2例行ESWL术，1例仅留置双J管。术后1个月拔管后自行排出。2例并发输尿管穿孔。RLU组取石成功18例，2例滑入肾内，经配合输尿管镜和腹腔镜直视下经皮肾穿刺取石成功，术后15例有伤口漏尿。PCNL组成功9例，无并发症。结论：USRL创伤小。术后恢复快。是治疗输尿管上段结石的较为满意的治疗方法。PCNL创伤小，取石成功率高，在结石靠近肾盂、儿童输尿管上段结石并同侧肾结石和结石以下输尿管狭窄时应优先考虑。但技术难度较大。RLU可作为URSL不成功后的辅助治疗方法。

ANALYSIS OF BURIED BUMPER SYNDROME AFTER PERCUTANEOUS ENDOSCOPIC GASTROSTOMY DUE TO USE OF A BUTTON‐TYPE KIT

Background: Buried bumper syndrome (BBS) is a rare complication of percutaneous endoscopic gastrostomy (PEG). Along with the widespread use of the button‐type kit, BBS is encountered frequently. Methods: In the present study, we examined causes and treatments for BBS among 1400 patients who had undergone PEG. Results: The causes of BBS after PEG were classified into two categories: early causes consisted of wound infection, inappropriate size of kit and severe lordosis, while late causes were inappropriate exchange of kit, rough management or weight gain. The treatments for BBS could be determined by the degree of wound infection, fistula and burial of the bumper. Conclusion: We prepared a flowchart for replacement, by which BBS can be managed safely and quickly without surgical or endoscopic intervention.     

Percutaneous nephrolithotomy of a staghorn stone in thoracic ectopic kidney

Congenital thoracic ectopic kidney is a very rare developmental anomaly and the rarest form of all ectopic kidneys. It is usually asymptomatic and discovered incidentally on routine chest radiography. Herein we reported the first case of staghorn stone in a thoracic kidney managed successfully by percutaneous nephrolithotomy.
