Observational data suggest spontaneous recanalization may permit delayed ipsilateral access; leaves open prospective validation before practice change.
What is the natural history and what are the risk factors for subclavian vein stenosis after catheter removal in hemodialysis patients?
Subclavian vein stenosis occurs in over half of hemodialysis patients after catheter removal, but spontaneous recanalization is common by 3 months, suggesting ipsilateral fistula creation may be possible if venography is normal at that time.
Hernández et al. (1998) studied this question.
