Objective To evaluate and compare the dosages of operator-incurred-radiation during the implantation of coronary sinus (CS) catheter between the approaches through inferior vena cava (IVC) with the steerable catheter and through supra vena cava (SVC) with the fixed curve catheter. Methods Two hundred and two patients were divided into two groups according to the different approaches of CS catheter insertion. IVC group (n = 122) :a deca-polar catheter with steerable curve was placed into CS through the femoral vein and the IVC. SVC group (n =80) :a fixed curve deca-polar catheter was inserted into CS through the jugular vein and the SVC. There was no obvious difference in gender, age, and echocardiogram between the two groups. All procedures were performed by the same three operators. The exposure time of each case and the dosage of operator-incurred-radiation during the procedure were measured. Results The catheters were positioned successfully inl20 patients in the IVC group and in all patients in the SVC group. The 2 failured in the IVC group were also failed in by attempting through SVC with fixed curve catheter. There was no significant difference in the exposure time between IVC group and SVC group[( 105 ± 12)s and ( 108 ± 19)s,P =0. 925]. The per sec operator-incurred-radiation was 0. 25 × 10-2 uGy/s in WC group and 1.38 × 10 -2 uGy/s in SVC group. This lead to significant decrease in the dosage of operator-incurred-radiation in IVC group[(0. 30 ± 0. 04) uGy vs ( 1.49 ±0. 27) uGy,P < 0. 001]. No cardiac or vascular complication was observed in both groups. Conclusions Insertion of coronary sinus catheter through IVC with the steerable catheter is associated with significantly less radiation than that through SVC with the fixed curve catheter without increasing time of the procedure. 相似文献

目的 经下腔静脉(IVC)放置冠状静脉窦(CS)电极导管理论上存在减少操作者放射剂量的可能性.本文在对比经IVC可调弯电极导管与经上腔静脉(SVC)固定弯电极导管置入CS操作的可行性和操作者所受的放射剂量.方法 202例患者,经下腔静脉组(IVC组)122例、经上腔静脉组(SVC组)80例,两组患者年龄、性别、超声心动图和心律失常类型方面差异均无统计学意义.IVC组采用可控弯10极电极导管,SVC组使用固定弯10极电极导管,由同一组术者操作.记录两组患者导管放置时曝光时间,并测定操作者所受放射剂量.结果 IVC组122例患者中有2例电极导管不能到位,改经SVC途径仍未成功;SVC组80例全部放置成功.两组平均每例曝光时间相似[(105±12)s vs(108±19)s;P=0.925].单位时间所受放射剂量平均值在IVC组为0.25×10-2uGy/s,SVC组为1.38×10-2uGy/s.IVC组和SVC组操作者平均每例接受放射剂量分别为(0.30±0.04)uGy和(1.49±0.27)uGy(P<0.001).两组皆未发现心脏和血管并发症.结论 与固定弯电极导管经SVC途径比较,可控弯电极导管经IVC途径置入CS电极导管的单位时间放射量明显降低,在不增加操作时间的同时可显著减少操作者所受放射剂量. 相似文献

目的描述一种用于定位房间隔穿刺关键解剖结构的简单可靠方法。方法在2012年3~11月心房颤动(简称房颤)消融术中,连续3次穿间隔失败的23例患者中应用下腔静脉(IVC)造影指导房间隔穿刺术(TP)。在右前斜45°透视下,将造影管远端置于IVC口下1 cm处注射5~10 ml造影剂。IVC、右房(RA)、右室流入道(RVIT)和右室流出道(RVOT)依次显影。RA,RVIT和RVOT之间围绕的无造影剂充盈的区域是主动脉根部及相邻组织。冠状窦(CS)电极经股静脉置入,其转弯处标志CS口上缘。右前斜45°投照下,合适的房间隔穿刺点(TPS)应在RA的中间、无冠窦的后下方、CS口的后上方。结果 23例均成功完成IVC造影指导下的房间隔穿刺(20例1次穿刺成功,3例2次成功),并达到房颤消融的所有终点。91%(21/23)的患者所有结构清楚显示,能清楚看到所有患者RA下缘、后缘和无冠窦,在2例中RA上缘不能清楚显示。由IVC造影提示的最佳TPS在22例患者中是合适的。在IVC造影图像中,沿无冠窦后缘最头侧与CS口上缘之间连线的中点画一水平线(AE),AE线平分为4段。在87%(20/23)的患者,最佳TPS是在AE线上的左半段。结论 IVC造影能提供关于TPS定位及其周围解剖结构的重要信息,IVC造影确定的TP很适合应用于房颤导管消融术。 相似文献

房间隔穿刺是目前心房颤动射频导管消融(下称消融)的必要步骤。大多情况下,只要正确掌握操作要领,训练有素的术者成功穿刺房间隔是不难的。但是有些情况下,例如患者已经接受过一次或多次房间隔穿刺术,房间隔卵圆窝疤痕形成,即使经验丰富的术者怎样调整穿刺点位置、重塑穿刺针头端的角度和增加穿刺力量,房间隔穿刺最终也难以成功。随着心房颤动消融的广泛开展,因房间隔穿刺失败而不能手术的病例并不少见。 相似文献

目的总结在行房间隔穿刺时根据冠状窦电极走行特征个体化选择右前斜位透视角度的实际应用体会。方法选择50例因接受房颤导管消融手术而需行房间隔穿刺的患者为研究对象。每例均先经左侧或右侧锁骨下静脉放置冠状窦电极,在后前位透视下,将房间隔穿刺针及长鞘管从上腔静脉回撤至冠状窦口上方1.0~1.5个椎体高度,然后在右前斜位透视下完成穿刺。右前斜位透视角度根据冠状窦电极走行特征选择。记录每例穿刺时的透视角度。结果50例均顺利完成房间隔穿刺,无并发症发生。穿刺时右前斜位透视角度为(35.5±87.21)°,其中多数病例(33例,66%)透视角度为25°~35°。透视角度与左房内径呈弱负相关(P=-0.055,r=-0.27)。结论根据冠状窦电极走行选择房间隔穿刺时的右前斜位透视角度,可以更好地展示房间隔平面,有利于穿刺点准确定位,提高穿刺的成功率及安全性。 相似文献

由中枢神经病变所致的吞咽困难患者,常需留置胃管以维持营养。对此类患者徒手插胃管往往失败。为解决病人留置胃管问题,既往有过内镜安置消化道营养管的报告,但这种方法我们使用起来仍觉不够理想。因此,我们企图寻找一种简便、安全、可靠的内镜放置胃管方法。经三年多来的反复实践,探索出一种放置胃管的胃镜导丝新方法,即胃镜导丝法。其操作简便迅速,可靠安全,现报告如下。 相似文献

在临床治疗中,常遇到穿刺细小血管或血容量不足的血管时,虽然针头已进入血管内,但回血不明显,甚至不见回血。对此,护理人员常认为是穿刺不成功,仍盲目穿刺,导致穿刺失败。分析静脉不回血的原因,关键在于输液器内液体的压力及静脉内血液的压力。如血容量不足,血管内压力低,静脉穿刺时可不回血。我们采用下面比较简单的方法较好地解决了上述问题,使穿刺成功率提高。具体做法是,输液用具中另准备一个弹簧夹,排气后,先关闭调节开关,挤压莫菲氏滴管,再用弹簧夹夹住莫菲氏滴管上段(此时滴管内呈负压状态)。静脉穿刺针进入皮肤后… 相似文献
