Description
Guo Li and co-authors test a CT sign for blocked central veins in dialysis patients in a 2026 study. Backup vessel routes hint at stenosis, and the team checked one route, the lateral thoracic pathway, on low-dose scans. Records covered 355 patients with kidney failure, split by catheter, fistula, or graft access.
The pathway sign appeared in 54.4 percent of scans against 12.1 percent for visible chest varices on exam, and both signs ran far higher in patients with stenosis. The CT sign caught over nine in ten stenosis cases in each access group, with sensitivity near 0.939 to 0.956 across them, far above the exam sign. A plain low-dose scan may thus flag vein blockage early.
