We studied angiographically the access route 1–27 months after the insertion of temporary dialysis catheters in 52 patients: 32 subclavian and 20 internal jugular. The two groups were statistically similar with respect to age, sex and race. The subclavian catheters were left in for a mean of 11.5 days (2–22) while the internal jugular ones were inserted for 15.8 days (5–25; p = 0.0015). One hundred percent of the internal jugular patients were free of any venogram abnormalities in their venous access return. In marked contrast, 50% of the subclavian sites had mild to severe strictures with 90% having 70–100% occlusion of the subclavian vein. Six patients had bilateral severe strictures. The long-term stricture rate of subclavian catheters in the subclavian vein was unacceptably high compared to the internal jugular route.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
