硬膜外腔阻滞对胸部手术应激反应的影响

目的 观察硬膜外腔阻滞对胸部手术应激激素和细胞因子的影响。方法20例食管癌手术病人,随机分为两组,每组10例,即全麻复令硬膜外腔阻滞(GEA)组和全麻(GA)组,分别测定麻醉诱导前、手术2h、手术4h、术毕、术后1d及术后3d的血浆去甲肾上腺素、肾上腺素、血清促肾上腺皮质激素(ACTH)、皮质醇、C-反应蛋白、IL-6及IL-10的水平。结果 血浆去甲肾上腺素和血清皮质醇GEA组术中术后无显著改变,但GA组术毕和术后1d显著升高(P<0.05),术后3d恢复至术前水平,组间比较前者有显著差异(P<0.05)。两组血浆肾上腺素、IL-10术中术后均无显著变化。两组血清ACTH、IL-6及CRP术中术后均显著升高(P<0.05),组间比较无显著差异。结论 硬膜外腔阻滞可以减轻胸部手术的应激反应。IL-6是较CRP更灵敏的反映组织损伤的炎性指标。     

腹部器官移植术后并发症的磁共振检查

目的探讨磁共振在腹部器官移植并发症中的诊断价值。方法对4例肝移植、5例胰肾联合移植及2例肾移植患者进行磁共振检查，检查时间在术后28d至2年，采用GE1．5TMR机型，成像技术包括常规平扫及增强扫描。结果4例肝移植，1例发生肝动脉狭窄伴肝坏死，1例发生下腔静脉血栓形成，1例为肝静脉与下腔静脉吻合口明显狭窄，1例为左右肝管明显狭窄；5例胰、肾联合移植中，1例并发急性排斥反应，1例为移植胰慢性排斥反应伴纤维化，1例为迟发性胰腺炎，移植肾4例正常，1例并发急性排斥反应伴肾梗死；2例单纯肾移植者，1例为肾动脉局限性中度狭窄，1例为肾动脉与髂内动脉吻合口处动脉瘤形成。上述病理改变均经组织病理检查和数字减影血管造影证实。结论磁共振可作为腹部器官移植并发症的一种无损伤检查手段，对于血管并发症，有其独有的优势。     

儿童硬膜外血肿的治疗

目的 探讨儿童硬膜外血肿的临床特点及其治疗方法。方法 回顾性分析我院2001年1月～2003年12月收治的儿童硬膜外血肿120例。结果 婴幼儿和学龄前儿童受伤原因以坠落伤及摔伤为主，7岁以上儿童以交通伤为主。65.8％(79/120)的患儿合并有颅骨骨折，格拉斯哥昏迷评分(GCS)平均13．6分。急性血肿除立即手术者外，其他于首次发现血肿1d后及3d左右再复查CT。手术者占57.5％(69/120)，术中发现血肿来源于板障出血的占44％(29/66)。结论 儿童硬膜外血肿的原发颅脑损伤相对较轻，颅骨骨折的发生率低于成人，板障出血为血肿形成的首要原因。有必要做多次CT检查，经恰当治疗预后良好。     

Avoiding complications in arthroscopic subacromial space and instability surgery

Arthroscopic shoulder surgery has become a safe tool for evaluation and treatment of a wide range of shoulder problems with few complications. With ever-improving technology (and commitment to motor skill development among arthroscopists), we can expect to maintain this low rate despite increasing procedure complexity. Avoiding complications in arthroscopic shoulder surgery requires careful preoperative planning, judicious patient selection, a thorough understanding of arthroscopic anatomy, and facility with arthroscopic techniques.     

妊娠黄体瘤1例报告并文献复习

目的：探讨妊娠黄体瘤（LP）的误诊原因。方法：对1例典型LP病例进行全面病理学检查和组化及免疫组化染色，与正常卵巢黄体进行对比分析，并复习文献。结果：LP均发生于妊娠后期，临床无明显自觉症状，其病理形态学、组织学、免疫组化反应与正常卵巢黄体相似。多在剖腹产时偶然发现而误为卵巢肿瘤。结论；LP为妊娠后期卵巢黄素化细胞的结节状增生，并非真性肿瘤。妊娠期出现卵巢明显增大，应首先考虑到本病的可能性。必要时术中可作活检，以避免误切卵巢。     

肝移植患者术后早期精神症状的观察

目的探讨肝脏移植术后早期精神系统并发症发生的原因和防治经验。方法回顾性分析 12 5例原位肝脏移植患者的临床资料 ,以术后 2周作为观察时点 ,分析肝脏移植术后早期精神系统并发症发生的原因 ,总结防治经验。结果有症状组和无症状组在性别、年龄、肝功能以及血环孢素A浓度方面无明显差异 ;但有症状组的无肝期时间 (93 74± 2 8 98)min和手术时间 (4 14 6 5±6 1 92 )min却长于无症状组 (P <0 0 5 ) ;另外 ,术前有无肝性脑病、术后感染以及静脉使用免疫抑制剂和术后精神症状的发生明显相关。结论肝脏移植术后早期精神系统并发症发生的原因是多方面的 ,通过积极的对症支持治疗 ,预后良好。     

Rebound intracranial hypertension after treatment of spontaneous intracranial hypotension

Spontaneous intracranial hypotension (SIH) is characterized by orthostatic headache and the cause is usually cerebrospinal fluid leaks in spine level. Most patients with SIH have a benign course. Epidural blood patch (EBP) is the treatment of choice when initial conservative managements are ineffective. We reported a patient with SIH diagnosed by using magnetic resonance imaging and radionuclide cisternography. Acute rebound intracranial hypertension developed after EBP and was successfully treated with intravenous osmotic agent.     

假体隆乳术后并发症的防治

目的探讨乳房假体隆乳术后并发症产生的相关因素及预防方法。方法对198例患者乳房假体隆乳术后1~17年出现的并发症进行分析,阐述防治措施,针对不同情况进行相应的处理。结果本组198例患者,其中92例患者随访半年至1年,除Ⅲ°包膜挛缩患者术后仍出现Ⅱ~Ⅲ°包膜挛缩外(包膜松解术后3例,包膜切除术后4例),余患者对治疗效果满意。结论乳房假体隆乳术后出现的并发症,多数是可以预防和治疗的,只要术中操作规范,对并发症及早准确的处理,是提高手术效果,减少并发症发生的有效方法。     

Aortic valve injury 10 years after tetralogy of Fallot repair

Summary Although recognized by pediatric cardiac surgeons, aortic insufficiency as a technical complication after tetralogy of Fallot repair is poorly documented, especially if it occurs late. The case of a boy with aortic insufficiency 10 years after complete tetralogy repair is described. No documentation in the literature other than summary statements in textbooks of this occurence was found.     

Amputation in elderly and high-risk vascular patients

Fifty-eight patients underwent lower limb amputation for arterial disease over a 30-month period. Mean age of the patients was 72 years. Cardiopulmonary and metabolic risk factors were present in the majority of the patients. Postoperative one-year and three-year mortality rates were 24, 40, and 76%, respectively. Contralateral amputation was required in one-third of the patients after a mean period of eight months. Only younger and healthier patients returned to a meaningful social life after appropriate prosthetic fitting. In view of the high mortality and morbidity rates, above-knee amputation seems a better choice than below-knee amputation in these elderly and high-risk patients.
