A symptomatic 1,400 g premature triplet underwent successful transcatheter coil embolization of patent arterial duct using the umbilical artery. One 3 mm x 3 cm Flipper coil was used with no angiographic residual shunt. To the best of our knowledge, this is one of the smallest preterm infants to undergo this transcatheter procedure. 相似文献

A transjugular snare technique was used to retrieve a stretched, residual mechanical detachable coil which extended from
the cavernous sinus to the femoral vein, obliterating the transpetrosal route for further embolisation. The coil was snared
by a microguidewire. Our new technique is described in this paper.

电解可脱卸弹簧圈栓塞治疗颅内破裂动脉瘤的疗效及影响因素 总被引:9,自引:1,他引:8
目的:探讨电解可脱卸弹簧圈(Guglielmi detachable coil,GDC)栓塞治疗颅内破裂动脉瘤的近期疗效及相关影响因素。方法:应用GDC栓塞治疗123例157枚动脉瘤,分析动脉瘤几何形态学、病情严重程度对栓塞效果及临床治疗的影响。结果:Hunt-Hess分级Ⅰ-Ⅱ级患中,预后良好(GOS>3分)为100%,Ⅲ、Ⅳ-Ⅴ级患中分别为95.0%、76.0%;窄颈动脉瘤完全栓塞率、大部栓塞率及部分栓塞率分别为92.4%、5.7%、1.9%,宽颈动脉瘤中分别为80.8%、13.5%、5.8%,大动脉瘤的疗效明显低于小动脉瘤。结论:动脉瘤的栓塞程度不仅与瘤颈大小有关,还受瘤体大小的影响。而临床预后与Hunt-Hess分级呈负相关。 相似文献

Objective To develop a Chinese-made electrolytic detachable coil (CEDC) that would allow patients to enjoy the benefit of electrolytic detachable coil without having to rely on the expensive Guglielmi detachable coil (GDC), and to test the safety and efficiency of CEDC. Methods Radiopacity of the marker of the CEDC was tested. The anti-strain force of coils and connection points were measured. In vitro and in vivo electrolyses were conducted. We produced 21 aneurysm models including lateral, bifurcation, and terminal aneurysm models, and embolized 18 models with CEDC. Results Radiopacity of the marker was satisfactory. Anti-strain of the coil and the connection point have shown the safety and efficiency of CEDC. Electrolysis in vitro and vivo, was similar to that of GDC. 83% of the aneurysm models were completely occluded. Coils were found to induce thrombosis in the aneurysm cavity, and could lead to a new endothelium over the entrance of the aneurysm, with organized tissue replacing thrombosis in 2 months. Conclusions CEDC is as efficient and safe as GDC. The marker, the ability to induce thrombosis inside the sac and the growth of new endothelium over the orifice are very satisfactory. 相似文献

Successful Embolization of Coronary Arteriovenous Fistula Using an Interlocking Detachable Coil 总被引:4,自引:0,他引:4
Although the efficacy and feasibility of coil embolization of coronary arteriovenous fistulas have been reported, the procedure
may be complicated by migration of the coil into peripheral vessels or pulmonary arteries. We report two cases of successful
coil embolization of such lesions using an interlocking detachable coil. This system can provide safer and more effective
coil embolization in patients with coronary arteriovenous fistula. 相似文献

AbstractThe aim of the investigation was the technical realization and approval of a new method for insertion and detachment of platinum alloy microcoils and other vascular implants via standard microcatheters. Flexible lightconducting fibers, 105 μm in diameter were connected to platinum alloy microcoils. It was examined whether an insertion wire, a lightconducting fiber and a platinum alloy microcoil could be advanced through a Tracker-18 (Target) microcatheter. The detachment of the attached coil from the lightconducting fiber was investigated. Platinum alloy microcoils can be attached to available lightconducting fibers in a reliable and reproduceable manner. Together with the fiber they can be advanced via a Tracker-18 microcatheter. Only extremely tortuous vessels may increase the friction to critical values. A Ho-YAG laser source was used. This allowed the instantaneous detachment of microcoils from laser fibers. In contrast to electrolytical detachment; no foreign substances are released to the blood stream. The detachment does not require waiting time and does not activate thrombus formation. Due to specific technical features, injuries of the vessel wall are avoided. After further miniaturization and adaption of the lightconducting fibers to the required characteristics; I aster detachment may have the potential to replace current methods such as electrolytical and mechanical coil detachment.
