The optimal choice of vascular access in a hemodialysis patient depends on a lot of factors including prognosis, the need for immediate use, presence of other comorbidities and patient’s comfort and personal choice. Options most commonly used include the most ideal arteriovenous (AV) fistula, AV graft and central vein catheters. Superior vena cava syndrome (SVCS) is a serious complication associated with central venous catheters (CVCs), often manifesting as facial and upper extremity edema. Long-term catheter use in hemodialysis patients increases the risk of venous stenosis and occlusion, which can lead to SVCS. However, SVCS presenting after central venous catheter removal in patients is rare.
We report a case of a 36-year-old female with end-stage renal disease on maintenance hemodialysis for five years. Initially, she had a non-tunneled catheter in the right internal jugular vein, later replaced by a tunneled catheter in the left internal jugular vein, which she used for four years. Two weeks prior to admission, she developed progressive swelling of the upper extremities, face, and neck without erythema or pain. Imaging studies revealed occlusion of the right brachiocephalic vein with collateral circulation through the azygos system, suggestive of chronic central venous stenosis from the prior right internal jugular vein catheter inserted four years prior to presentation. Decision to remove the left tunneled catheter at the left internal jugular vein was then done during admission, and she continued hemodialysis using her AVF at her left arm. In the interim, noted improvement of facial swelling. However, three months after removal, noted recurrence of progressive facial swelling prompting readmission. Central venogram was then done revealing left brachiocephalic vein stenosis thus balloon venoplasty was done. Improvement of facial swelling was then observed and was discharged.
SVCs in hemodialysis patients is commonly associated with prolonged catheter use, leading to endothelial injury, thrombosis, and stenosis. Several case reports shows that these are commonly seen in patients with present central vein catheters at time of diagnosis and rarely as a complication of catheter placement, as seen in this patient. This case highlights the importance of timely transition from catheters to permanent vascular access, given the long-term complications of central venous stenosis. Despite no active catheter in the affected vein at presentation, the history of prior catheterization suggests a delayed manifestation of stenosis.
