| | cases of transfemoral catheterization for selective cerebral angiography are reviewed. The technique and complications for selective femorocerebral angiography were discussed. The selection of catheter shapes was determined by the vessel whish was to be catheterized and by the configuration of the aortic arch in elderly patients. Cerebral vasopasm caused by catheter stimulation was the cause leading to cerebral bloodsupply insufficiency too.The cerebral trombosis may be another cause causing cerebral infarc... | | 本文报告了161例经股动脉插管选择性脑血管造影,对选择造影的一些有关技巧及某些并发症进行了讨论。认为导管选用是否恰当,将直接影响插管能否成功和并发症的发生。导管尖端塑形要随选择血管的不同而各有所异。提出老年病人因血管解剖关系的特殊变化,导管塑形也要相应改变,认为导管刺激引起脑血管痉挛也是造成脑供血不足的一个原因。提出选择性脑血管造影后,脑血栓形成可能是最终导致脑梗塞的另一个原因。最后对并发症的预防进行了简单的讨论。 | | 文摘来源 | | The comparison of radiofrequency catheter ablation(RFCA)of right-sided accessory pathways(APs)in patients with Ebstein's anomaly(group I)to normal heart(group II)was studied.The results showed there were not significantly difference in heart rate of tachycardia,anterograde and retrograde refractory period between group I and group II.APs all located in right posteroseptal and right posterolateral wall;RFGA was successfully performed in patients.There were not also difference in procedure time,fluoroscopy ti... | | 为探讨心内结构异常合并房室旁道患者射频消蚀的难易程度,对射频消蚀8例先天性心脏病Ebstein畸形(Ⅰ组)与20例合并右侧房室旁道心内结构正常者(Ⅱ组)进行观察。结果显示:两组心动过速的心室率、旁道的前传和逆传不应期均相近,差异无显著性;两组消蚀导管的选择与操作过程无不同之处,其总操作时间、X线投照时间和放电次数分别为:110±63minVS103±55min、45±21minVS39±17min、6±4次VS6±3次,P均>0.05。且两组病例均一次消蚀成功。结果说明Ebstein畸形合并房室旁道的射频消蚀同样较易成功。手术操作需轻柔,对合并右心功能不全者应避免心动过速的诱发;倒“U”形导管塑形,可加强导管的稳定性。 | | 文摘来源 | | In a group of 80 cases receiving TEAP,a comparison was made between this 4-step and traditional TEAP. Our method is as follows:plasticky of TEAP electrode;three mapping electrode; in troducing stimulus; to ensure the optionalthreshold value. Threshold value (19.0±3.1)V,asa result of the 4-step method,was significantly lower than traditional value(27.61±4.8)V,(P<0.05).In 84%(67/80)patients,the discomfort (burning)were relieved,and the patients are morewilling to take the examination,Therefore,the 4-step meth... | | 在为80例患者行经食道心房调搏(Transesophagealatrialpacing;TEAP)电生理检查术中,将用传统方法所测得的平均起搏阈值〔简称阈值(27.61±4.8)V〕作为基础对照,与分别用本文四步操作方法,即导管塑形;三个标志电极定位;诱导刺激;确定佳阈值所测得的平均阈值〔(19.0±3.1)V〕相比较,结果显示:用本文四步法可以显著降低平均阈值(P<0.05)。随着阈值的下降,可使84%(67/80)患者受检之苦明显减轻。 | | 文摘来源 | |   | | << 更多相关文摘 |
