保留冠状动脉的猪心螺旋形心室肌带的解剖

Objective Based on the Helical Ventricular Myocardial Band (HVMB) theory proposed by Torrent-Guasp,the ventricular myocardial hand extends from the root of the pulmonary artery to the root of the aorta with two helical coils.This new theory is considered as a revolutionary concept for further understanding the global, three-dimensional and functional architecture of the ven- tricular myocardium. No repot had described techniques for disecting HVMB while keepin～ the integrity of the coronmy artery sys- tern. We explored techniques for dissecting HVMB in swine.Methads 33 fresh swine hearts were randomly divided intoll groups, 3 bearts in each. 160% barium sulfate (type I)suspmmion was injected into the coronary artery system. The coronary arteries were li- gated. The strial tissue was removed following puuing the hearts in boiling water then cooling for several hours. The superficial coro- nary vessels and fat tissue around the atrio-ventricular taxi inter-ventricular sulcus we～'e preserved. Some branches of the left anterior descending artery, distal segment, of posterior descending branch, and middle and distal segment of obtuse marginal branches were mu- tilated appropriately. HVMB dissection was completed with fingers in accordnce with Torrent Guasp' s technique. Results A contin- ued bundle of muscle, originated at the root of pulmonary artery and ended at the root of aorta, was unwrapped along the major dire- tion of the cardiac muscle fiber in all of the 33 hearts with spating of the coronary artery. The swine hearts' ventricular myocandium was cumosed of two loops, with basal loop firm the root of the pulmonart artery to the anterior papillary muscle and apical from the beginning of the anterior papillary muscle to the root tithe aorta. Each loop consisted of two segments: the right segment-coincid- ing with the right ventricular free wall and the left segment-coinciding with the basal d the left ventricular free wall. Posterior papillary muscle, which belongs to the descendant segment, denmrcated the border between the descendent and the ascendant of the HVMB's apical loop. Conclusion Although controversies about the theory of the HVMB remain, we have dissected the HVMB in the swine hearts' ventricular myocardium successfully with sparing of the coronary artery systems. This dissection procedure provides technical information for the studies of associated diseases based on the theory of HVMB.     

Super-chrged带蒂TRAM皮瓣乳房再造一例

患者女，43岁。8年前，因左乳肿物曾行纤维腺瘤切除术，术后4年，因左乳瘢痕增大变硬行左侧乳房切除术，病理示黏液型低度恶性纤维组织细胞瘤，术后未行放射及化疗。检查：一般状况好，无手术禁忌证。患侧乳房缺损，无锁骨下凹陷，腋前襞丰满，胸大肌发育正常。对侧乳房基本正常，体积不大。入院诊断：手术后左侧乳房缺失。治疗过程：患者在全麻下行Super-charged TRAM皮瓣左侧乳房再造术。术中形成以右侧为肌蒂的TRAM皮瓣，同时尽可能长地留取右侧腹壁下动静脉系统备用，左侧腹壁下动静脉予以结扎。     

带锁髓内钉治疗股骨干粉碎性骨折

髓内钉治疗长骨骨折，属髓内轴心性固定，具有手术切口小，对软组织损伤少，固定牢固防旋转并适时改为弹性固定，便于早期进行功能锻炼，并发症少等优点，已得到公认。自1999年11月～2003年10月，笔者采取小切口骨折复位．扩髓带锁髓内钉治疗股骨干粉碎骨折22例，取得了良好的效果，报告如下。

颊脂垫转移修复口腔内组织缺损的疗效观察

1977年Egyedi首先提出了使用颊脂垫转移修复口鼻腔洞穿封闭口腔上颌窦瘘，近10年来，有关颊脂垫的解剖学研究及利用带蒂颊脂垫移植，修复颌面部软组织缺损及骨移植Ⅰ期重建上颌骨等研究已经有很多的报道。作自2000年开始使用颊脂垫修复颊粘膜缺损以及口腔上颌窦瘘共8例，均取得了较好的临床效果。     

手术室护生带教体会

临床实习是护理教学中的最后阶段，是护生将所学的理论知识与实践相结合使之进一步充实、巩固和提高的重要教学环节。随着现代医学科学的发展，对护理工作提出了更高的要求，手术室护理质量的优劣直接影响手术治疗的成功和失败，而护理带教是提高护理质量必不可少的重要环节。为了使护生在有限的时间内较全面掌握手术室的护理知识，下面就本人二十几年来的工作实践，浅谈手术室护生实习带教的体会。     

腹股沟带蒂皮瓣移植术围手术期的临床护理

腹股沟带蒂皮瓣是临床常用的轴型带蒂皮瓣之一。主要用于手、腕部皮肤缺损。其优点为皮瓣血循环可靠，质地优良，有韧性，弹性好，皮瓣面积大，供皮区隐蔽，不影响美观，而且易于切取和成活。围手术期的护理关系到手术的成败。我科于2000—2004年对68例患者行腹股沟带蒂皮瓣移植术，现将护理介绍如下。     

对提高学生临床实践能力的思考
