Axillary arteries are less calcified and tortuous than iliofemoral arteries Axillary artery minimal luminal diameters are usually >5.0 mm even in patients with iliofemoral artery diameters < 5.0 mm Axillary and transcaval access are the only non-surgical fully percutaneous options for large-bore arterial access for TAVR or mechanical circulatory support devices.
腋动脉的钙化程度和迂曲程度低于髂股动脉。即使在髂股动脉直径小于5.0毫米的患者中,腋动脉的最小管腔直径通常也大于5.0毫米。腋动脉入路和经腔静脉入路是经导管主动脉瓣置换术(TAVR)或机械循环支持装置进行大口径动脉入路的仅有的非手术完全经皮选择。
