A triple coaxial catheter system for subselective visceral artery catheterization and embolization: preliminary clinical experience.
We developed a triple coaxial catheter system (TCCS) which consists of a 6.1 Fr outer, a 4.1 Fr intermediate, and a 3.0 Fr inner catheter, all coated with a lubricant. The TCCS was used in seven patients with hepatic tumors, after several attempts to access a targeted vessel with conventional catheters and guidewires failed to reach the targeted vessel. No complications were encountered with the use of this system. TCCS may be a useful device for selective abdominal arteriography.
