selective catheterization
Targeted placement of a catheter into a specific arterial branch for isolated contrast injection and imaging.
Full Definition
Selective catheterization is an angiographic technique where a catheter is specifically positioned within an individual arterial branch to allow isolated contrast injection and detailed visualization of that vessel and its tributaries. This approach provides superior image quality compared to non-selective techniques by avoiding overlap from adjacent vessels and allowing higher contrast concentrations in the target vessel. Selective catheterization is essential for detailed evaluation of stenoses, planning interventional procedures, and providing therapeutic access for treatments such as angioplasty or embolization. The technique requires specialized catheters, guidewires, and operator expertise to safely navigate tortuous anatomy.
Usage
Usage note: Often shortened to 'selective' in procedural contexts; implies intentional targeting of specific vessels.
