Visualization of arterial and arterial graft patency by intravenous radionuclide angiography

A method of visualizing patency of arteries and arterial grafts by means of intravenous ^99mTc pertechnetate using a Nuclear Chicago Pho/Gamma HP camera is described. Polaroid pictures showing normal arteries in the upper and lower limbs, as well as partial and complete occlusion of arteries and the state of arterial bypass grafts in pre- and postoperative patients are compared with conventional arteriograms. The advantages and limitations of this method are discussed.     

髂内动脉-前列腺动脉化疗栓塞治疗晚期前列腺癌

目的探讨经髂内动脉-前列腺动脉化疗栓塞晚期前列腺癌的疗效。方法对22例晚期前列腺癌患者其中C1期5例，C2期7例，D1期8例，D2期2例，共行25次介入治疗。所用药物剂量分别是：卡铂400mg，丝裂霉素20mg，表阿霉素50mg，长春新碱1mg；栓塞剂选用明胶海绵和碘甘油。结果22例患者自治疗后第1周，病人均出现前列腺质地变软和体积缩小；第2～3周后体积缩小20％～40％；3例术后有神经合并症；1例臀部皮肤组织缺血坏死；8例于化疗栓塞2～3周后行经尿道前列腺汽化电切术。随访5—36个月，尿流率明显改善，残尿量减少或消失。结论经导管双侧髂内动脉超选择（前列腺动脉）化疗栓塞治疗晚期前列腺癌疗效肯定，为综合治疗晚期前列腺癌增加了新的治疗手段，尤其是对非雄性激素依赖性前列腺癌或内分泌治疗无效者更有意义。     

踝臂指数评价冠心病患者下肢外周动脉病临床研究

目的通过测量踝臂指数(ankle-brachial index, ABI)评价我国住院冠心病(coronary arterial disease, CAD)患者下肢外周动脉病(Peripheral arterial disease, PAD)的发病情况.方法对入院的163例CAD患者进行踝臂指数测定,并进行资料收集和统计学处理.结果 163例CAD患者中发现70例合并外周动脉病(平均ABI 0.63).与非PAD组相比,PAD组患者与年龄 (P=0.000),糖尿病史(P=0.000) 有统计学意义,而与吸烟史(P=0.731), 高血压病史(P=0.187)和血脂异常(P=0.614)无统计学意义.结论通过测量ABI确诊PAD简便易行;CAD患者易合并PAD,冠状动脉旁路移植术(Coronary artery bypass grafting, CABG)患者合并PAD尤为常见;CAD合并PAD多见于高龄和糖尿病.
