crossover technique
Interventional approach where access is gained from the contralateral side to reach the target vessel.
Full Definition
The crossover technique in vascular intervention involves gaining vascular access from the opposite side of the body to treat the target lesion. Most commonly performed as contralateral femoral access to treat ipsilateral iliac or lower extremity disease, this approach offers several advantages including improved catheter support, ability to treat complex anatomy, and management of access site complications. The technique requires crossing the aortic bifurcation and may involve specialized catheters and wires designed for contralateral navigation. Success depends on adequate aortic dimensions and absence of severe iliac tortuosity or disease at the access site.
Usage
Usage note: Distinguish from 'crossover stenting' which refers to covering side branches with stent struts.
