title: [Development and clinical application of double catheter system for angiography].
abstract: Simultaneous double angiography of the two main branches of the aorta usually requires bilateral puncture of the femoral arteries. A double catheter system was devised to avoid this inconvenience. This system is composed of a 7F sheath with a valve of two small holes and two 3.5F catheters. Using this system and DSA, simultaneous double angiography of the two main branches of the aorta was performed with only one puncture site of a femoral artery in five cases. In four cases the splenic vein, superior mesenteric vein and portal vein were all opacified simultaneously. This system promises to be useful for visualization of the portal venous system and can be used for other simultaneous double angiography.
