A translumbar sheath is described that is suitable for performance of selective coronary and brachiocephalic arteriography when the extremity arteries are blocked. The sheath has been adapted to a needle and catheter, which are introduced as a unit into the aorta at the T-12 level. With the needle and catheter removed, the sheath can be used safely to exchange catheters for left ventriculography and selective studies of branches of the thoracic aorta without excessive retroperitoneal bleeding.
描述了一种经腰鞘，当肢体动脉阻塞时，它适用于进行选择性冠状动脉和头臂动脉造影。该鞘已适配于针和导管，它们作为一个整体在T-12水平引入主动脉。拔出针和导管后，该鞘可安全地用于更换导管以进行左心室造影和胸主动脉分支的选择性研究，而不会出现过多的腹膜后出血。
