乳腔镜下前哨淋巴结活检和腋窝淋巴结清扫术的临床研究（附36例报告）

目的探讨乳腔镜下乳腺癌前哨淋巴结活检和腋窝淋巴结清扫术的可行性及可靠性。方法采用亚甲蓝染色法在乳腔镜下切除36例乳腺癌患者的前哨淋巴结SLN）和腋窝淋巴结（ALN），随后行患侧全乳腺切除术。结果36例患者SLN检出率为97．22％（35／36），灵敏度为92．86％（13／14），准确率为97．14％（34／35），假阴性率为7．14％（1／14）。ALN每例切除数目12—21枚。结论乳腔镜下前哨淋巴结活检和腋窝淋巴结清扫术准确可靠，并发症少，易于临床开展。

Effect of mechanical ventilation on mortality rate in patients with acute left ventricular failure and respiratory failure

Objective To evaluate the clinical value of CT three-dimensional(3-D) imaging on diagnosing of bone and joint diseases.Methods The imaging findings of 357 cases proved by operation or clinic were analyzed retrospectively by the 3-D imaging.The diagnosis accuracy of 3-D imaging was compared with that of routine CT.3-D images were obtained by surface shade display(SSD),multi-planar reconstruction(MPR),maximum intensity project(MIP) and volume rendering(VR).Results In 357 patients,257 cases were traumatic disease,100 cases were non-traumatic disease.The diagnosis accuracy of 3-D imaging was 98.3%,which was higher than that of routine CT(P<(0.05)).3-D imaging could show the length and shape of fracture line,and the size,shape and location of tumorous focus and fragment of bone.Conclusion CT 3-D imaging can show the structure and focus of bone and joint directly and clearly,which has the outstanding advantage to showing complicated structures or deep joint.The diagnosis accuracy of 3-D imaging is high,and helpful in the choice of clinical treatment.
