Abstract
To compare the feasibility of the distal radiopaque marker, the length of the distal radiopaque marker of the microcatheter, the shaping ability and stability of the head end of the microcatheter, and provide reference for its application in endovascular therapy of cerebrovascular diseases. Seven types of commonly used microcatheter heads were used for X-ray fluoroscopy on Siemens digital flat panel angiography machine, and the fluoroscopy of the distal radiopaque marker was observed. Six samples from each brand were selected to measure the distance between the head end of the microcatheter and the distal development ring, and the difference in length was compared. Six microcatheters of each brand were selected for steam fumigation and shaping according to the instructions. Thereafter, the endovascular treatment process of intracranial aneurysms was simulated to compare their shaping ability and stability after plasticity. After fluoroscopy on the digital flat panel angiography machine, the distal markers of Echelon-14 and Prowler-14 were highly recognizable by naked eyes. In the distance detection test between the head end of each microcatheter and the distal radiopaque marker, the distance between the head end of the Presgo-14 microcatheter and the distal radiopaque marker was the shortest (0.492 mm), while the Echelon-10 microcatheter was the longest (0.866 mm). In the endovascular treatment experiment of steam fumigation shaping simulated intracranial aneurysms, Headway-17 microcatheter had the best shaping ability and stability after shaping, and Presgo series microcatheter had similar shaping retention ability to Echelon series microcatheter. All types of microcatheters have their own characteristics. Extensive understanding of the characteristics of different brands of microcatheters will facilitate their better application in nerve endovascular treatment.
