颅内假性动脉瘤的手术治疗

目的探讨颅内假性动脉瘤的诊断和手术方法。方法回顾性分析16例手术治疗的颅内假性动脉瘤病人的临床及影像学特点．其中创伤性9例，感染性7例。结果出院时临床状况优良11例，轻残3例，死亡2例（其中1例为创伤性，术后发生脑梗死）。对12例行3个月。5年门诊随访，均未发生再出血。结论颅内假性动脉瘤是颅内动脉瘤中特殊且较复杂的类型，其诊断和处理策略与一般动脉瘤不同。提高对颅内假性动脉瘤的认识，以及有效应用神经外科技术，可以降低假性动脉瘤的手术风险，改善预后。     

Perceptions of facial aesthetics in surgical patients with basal cell carcinoma

BACKGROUND: Basal cell carcinoma (BCC) is a non-melanoma form of skin cancer that is frequently localized within the cervicofacial area. So far, little research is available on how patients perceive their facial aesthetics after surgical treatment for BCC. OBJECTIVES: To analyse (i) if there was a statistically significant improvement over time with regard to the perceived facial aesthetics of surgical patients; (ii) if there was a significant difference between primary and recurrent BCC patients; and (iii) between patients who had Mohs micrographic surgery (MMS) or surgical excision (SE). To assess (iv) which baseline perceptions and/or clinical parameters may predict the evaluation of facial aesthetics at 6 months after surgery. METHODS: Parallel to a clinical trial, a survey was carried out in which patients were asked, by means of a newly developed disease-specific questionnaire, about perceptions with regard to their facial aesthetics before and after surgery. RESULTS: Aesthetic perceptions of all surgical patients improved over time. There was no statistically significant difference on facial aesthetics between the group with a primary or recurrent BCC and patients treated with MMS or SE. Results also showed that the evaluation of postsurgical facial aesthetics can be predicted by both visibility of the tumour and preoperative perceptions. CONCLUSION: It is recommended to administer preoperatively a short questionnaire in which perceptions related to facial aesthetics are included. In doing so, physicians will become more familiar with the aesthetic problems patients might have regarding their afflicted facial site. Ultimately, it may help physicians in deciding whether patients will benefit from additional cosmetic procedures after surgery.     

暴露前牙龈下残根进行桩冠修复

改良(足母)趾腓侧皮瓣修复拇手指指腹缺损

目的介绍改良躅趾腓侧皮瓣修复拇、手指指腹缺损的手术方法。方法对15例拇、手指指腹缺损的患者，采用改良的躅趾腓侧皮瓣移植修复。该皮瓣在传统躅趾腓侧皮瓣设计方法基础上，将皮瓣腓侧缘及近端分别向背侧及趾蹼侧移动，从而避开口径细小又紧贴于皮下的躅趾腓侧浅静脉，直接游离第一跖背浅静脉；皮瓣的动脉和神经游离仍以常规方式进行。结果术后15例皮瓣全部成活，未发生动、静脉危象。12例获得4～11个月随访，3例失访。手功能评定：优10例，良2例。皮瓣两点分辨觉为4～8mm，12例对皮瓣外形满意。供区行走无影响，步态正常。10例对供区外观满意，2例欠满意，其中1例蹲趾腓侧偶有触痛。结论应用改良躅趾腓侧皮瓣可显著降低手术难度，提高成功率。     

逆行隐神经岛状皮瓣的临床应用

目的 报告逆行隐神经岛状皮瓣的临床应用结果。方法 应用这种技术修复6例足跟部软组织缺损,切取的皮瓣面积为4cm×6 cm至7cm×10 cm。结果 所有的皮瓣完全成活,取得了满意的效果。1例术后4d发生表浅感染,经换药愈合。结论 大隐静脉、隐神经和伴行的动脉网是该皮瓣的轴,该皮瓣具有血管解剖恒定、血管蒂长和操作简单等优点,而且较薄,适宜修复足部软组织缺损。     

胰腺闭合性损伤的外科诊治探讨

目的探讨胰腺闭合性损伤诊断和外科处理的方法。方法分析20例胰腺闭合性损伤的诊断，手术处理和预后。结果17例治愈，死亡3例，死亡率15，并发胰瘘2例，假性囊肿2例，腹腔脓肿1例。结论CT、B超及血淀粉酶检查对胰腺损伤仍具有一定的诊断价值。术中关键是保持警觉，按胰腺损伤情况选择适当的术式。

间接测热法和反向Fick氏法测定心脏手术病人术后氧耗量的比较

目的 采用反向Fick氏法和间接测热法测定心脏手术后病人的全身氧耗,并比较两种测量方法的相关性和准确性。方法8例心脏手术术后病人,分别在入ICU后2h和6h时同时采用反向Fick氏和间接测热法测定病人的全身氧耗量。结果 间接测热法和反向Fick法测得氧耗分别是(16±30)ml·min-1·m-2和(127±23)ml·min-1·m-2,前者的测定结果显著高于后者(P<0.01)。相关分析显示两者有较好的相关性(r=0.92,P<0.01)。采用Bland和Altman统计分析提示两种测定结果的平均偏离值为(35.5±13.4)ml·min-1·m-2,其95％的分布范围是(9～62)ml·min-1·m-2,提示两种测量结果间的一致性较差。结论 两种方法测定心脏病人术后全身氧耗的结果有明显差异,其中反向Fick氏法的测定结果误差大、准确性差,而间接测热法是较好的临床选择。     

合并异常冠状动脉法洛四联症和右心室双出口一期根治术

目的 总结合并异常冠状动脉的法洛四联症和右心室双出口一期根治术的经验，探讨有关外科技术的改进。方法1995年6月至2002年6月完成该类一期根治术12例，其中2例采取了肺动脉移位、3例在游离的左前降支下加宽右室流出道、5例改变右室切口并在冠状动脉下缝合、2例经肺动脉和右房疏通流出道。结果无手术死亡。随访3个月～6年，无晚期死亡和并发症发生。结论合并异常冠状动脉的法洛四联症和右心室双出口的一期根治手术是可行的，且效果良好，但必须采用适当的外科技术以保护异常的冠状动脉。
