Subhepatic collections complicating laparoscopic cholecystectomy: Percutaneous management

Ten patients with subhepatic fluid collections complicating laparoscopic Cholecystectomy were successfully treated by interventional radiological procedures. The series included five abscesses, three hematomas, one biloma, and one serous collection. Abdominal pain or fever developed from 3 to 21 days after the laparoscopic intervention. All patients were asymptomatic 72 h after percutaneous drainage and there were no complications related to the procedure. Subhepatic fluid accumulations are common findings after laparoscopic cholecystectomies and have been considered an unreliable indicator of infection or other postoperative complications. However, the significance of these collections should not be underestimated in symptomatic patients. In such cases we propose diagnostic aspiration and drainage, when necessary, to safely and promptly establish the precise diagnosis and treatment. More serious complications can be avoided by early percutaneous intervention.

A "grapple hook" technique using a deflectable tip catheter to facilitate complex proximal circumflex interventions.

We present two patients with angulated, proximal left circumflex lesions, one a chronic total occlusion and one an acute subtotal occlusion. In both cases, use of the deflectable tip Venture Catheter (Velocimed, Minneapolis, MN) facilitated guide wire passage and successful percutaneous coronary intervention (PCI) after prior attempts at guide wire passage with standard wires were unsuccessful.     

New approach to management of intraaortic balloon pumps in patients with peripheral vascular disease: Case reports of four patients requiring urgent IABP insertion

Four selected cases of emergent IABP insertion in PV patients are presented. After angiographic documentation of critical iliac stenosis, conservative peripheral angioplasty was performed prior to IABP insertion. No patient experienced a peripheral ischemic event associated with IABP use. © 1992 Wiley-Liss, Inc.     

经皮附睾穿刺取精精子冷冻复苏后卵细胞胞质内单精子注射治疗无精子症的初步研究

目的:回顾性分析27例无精子症患者经皮附睾穿刺取精术(PESA)所获精子冷冻复苏后行卵细胞胞质内单精子注射(ICSI)治疗后的效果及妊娠结局。方法:将诊断性附睾穿刺以及PESA治疗周期ICSI后所剩余活精子以常规方法加以冷冻,将复苏后找到了足量活精子并行ICSI的病例归为冻精组,而采用新鲜PESA活精子ICSI的病例则归为对照组。比较冻精组与对照组的受精率、种植率、临床妊娠率,同时分析两组间的妊娠并发症、新生儿出生及畸形等情况。结果:冻精组15个周期、对照组100个周期分别注射MⅡ期成熟卵子163、1 157个,受精率冻精组显著高于对照组(84.05%vs73.29%,P<0.05),种植率、临床妊娠率则两组间差异无显著性(23.07%vs15.73%;53.33%vs37.00%,P>0.05),新生儿出生体重差异亦无显著性(P>0.05)。冻精组共妊娠8例,已分娩5例,继续妊娠3例。对照组妊娠37例,已分娩30例,1例死胎;继续妊娠3例;流产4例。两组均未出现重大的妊娠并发症及新生儿畸形。结论:采用PESA冷冻精子ICSI是治疗男性无精子症的一种经济、有效、安全的方法;但PESA冻精复苏率有待于进一步提高。     

经皮椎体成形术与椎体后凸成形术治疗胸腰椎压缩性骨折的临床疗效比较

目的比较经皮椎体成形术与椎体后凸成形术治疗胸腰椎压缩性骨折的临床疗效。方法对98例胸腰椎压缩性骨折，根据手术方法不同分为椎体成形组和椎体后凸成形组。比较两组术前术后椎体前缘、中线、后缘高度变化，疼痛视觉模糊评分（VAS），手术时间，出血量等方面的差异。结果两组对椎体高度的恢复比较差异有统计学意义（P〈0．01），VAS、手术时间和出血量比较差异无统计学意义（P〉0．05）。结论经皮椎体成形术与椎体后凸成形术具有创伤小、手术时间短、出血量少等微创优点，而椎体后凸成形术具有较好的复位作用。     

微创经皮钢板骨桥接术联合锁定加压钛板治疗胫骨远端骨折

目的探讨微创经皮钢板骨桥接术（minimallyi nvasive percutaneous plate osteosynthesis，MIPPO）联合锁定加压钛板（locking compression plate，LCP）治疗胫骨远端骨折的近期疗效。方法2004年6月～2006年3月采用MIPPO联合LCP治疗胫骨远端骨折16例，AO分型：43A1型7例，43A3型5例，43B1型2例，43C3型2例。采用3种方法复位胫骨骨折后插入LCP，用锁定螺钉固定。结果16例随访5～20个月，平均11，5月。16例切口一期愈合，骨折无延迟愈合、畸形愈合、断钉、断板等并发症。术后X线检查4～12周（平均7．6周）骨痂形成并开始部分负重，8～20周骨性愈合（平均16周），此时开始完全负重。3例出现胫骨远端内植物局部不适。根据美国足踝骨科学会评分系统对踝关节功能评分，优14例（87．5％），良2例（12，5％）。结论MIPPO具有创伤小、固定牢靠、可早期功能锻炼等优点，近期疗效满意，是治疗胫骨远端骨折的有效方法。     

Spontaneous migration of an inferior vena cava filter resulting in cardiac tamponade and percutaneous filter retrieval.

Thromboembolic disease accounts for thousands of hospitalizations every year in the US. Its primary management consists of anticoagulation. However, in certain instances this may be contraindicated or not sufficient. Mechanic occlusion of the inferior vena cava (IVC) becomes then a viable alternative. In this case a 35-year-old man presented with a saddle pulmonary embolus but was unable to be anticoagulated due to intestinal bleed. A removable IVC filter was then placed. The filter spontaneously migrated into the right atrium causing severe tricuspid regurgitation, perforation of the atrial wall, and cardiac tamponade. The device was successfully retrieved percutaneously and the patient discharged from the hospital in stable condition. This case illustrates the potentially lethal complications associated with the use of IVC filters, as well as the possibility to percutaneously recover them from within the right atrium.     

内镜联合肝动脉栓塞化疗、射频消融治疗肝细胞癌合并胆管癌栓

目的探讨内镜联合肝动脉栓塞化疗（transcatheter arterial chemoembolization，TACE）、射频消融（percutaneous radiofrequency ablation，PRAF）治疗肝细胞癌（hepatocellular carcinoma，HCC）合并胆管癌栓的治疗效果。方法回顾总结1999年1月～2005年12月收治的65例肝细胞癌合并胆管癌栓的诊疗情况。结果65例中，均行内镜胆道引流术或EST及取栓，联合TACE，PRAF治疗。本组无手术死亡。癌栓清除率为95．4％（62／65），肿瘤坏死率为96．9％（63／65），1年生存率为60．0％（39／65），3年生存率为38．5％（25／65）。结论内镜联合TACE及PRAF治疗肝细胞癌合并胆管癌栓不失为一种行之有效的微创治疗方法，疗效优于单纯的内镜、TACE及PRAF治疗。     

经皮气管切开术在危重症患者中的临床应用

目的总结近年来我科经皮气管切开术在临床应用时遇到的困难及教训。方法应用PT技术21例,并与常规气管切开术32例作对照研究。结果PT可明显缩短手术时间、减少术中及术后的出血量且创伤小,拔管后切口愈合快。结论PT是危重患者快速建立长久人工气道的好方法,患者痛苦小,两者并发症的发生无明显差别,但PT不能完全取代正规气管切开术。
