Ans. B: Aeriography Seldinger needle is used for cannulization or catheterization employing the Seldinger technique. It has: Thin wall outer cannula ending in blunt tapered point. Fitted stylet has sharp cutting tip with a sho bevel. Blunt, round ended stylet included for plugging of outer cannula after inseion. Has kidney shaped flange for ease of handling. Transfemoral aerial access for coronary angiography or angioplasty is the norm for most cardiologists. Although this carries the advantage of ease of access as a result of the superficial location of the large caliber femoral aery in the groin, it can also potentially cause rare vascular complications, such as pseudoaneurysms, aeriovenous fistula, aerial occlusion, nerve injury and most seriously, retroperitoneal bleed. In addition, transfemoral approach may also be unsuitable in some patients for a variety of reasons; these include severe aooileofemoral obstructive disease, abdominal aoic aneurysm, groin infection or gross obesity.
