Summary
Central venous stenosis or occlusion, often caused by thrombosis or fibrosis, is a common complication of central venous catheters. Interventional radiology, including angioplasty and stent implantation, is the primary treatment for symptomatic lesions.
Area of Science:
- Vascular Surgery
- Interventional Radiology
- Nephrology
Context:
- Central venous stenosis and occlusion are frequent complications associated with indwelling central venous catheters.
- These lesions can result from thrombosis or fibrosis, leading to progressive narrowing or blockage of the vein.
Purpose:
- To outline the management of symptomatic central venous stenosis or occlusion that impedes angio-access for hemodialysis.
- To highlight interventional radiology as the preferred treatment modality.
Summary:
- Interventional radiology techniques, including anticoagulation, local fibrinolysis, angioplasty, and stent implantation, are effective for treating central venous lesions.
- Percutaneous treatments offer a simpler and less invasive alternative to surgical interventions like thoracotomy.
Impact:
- Effective management of central venous stenosis/occlusion improves outcomes for patients requiring hemodialysis.
- Understanding these complications is crucial for appropriate central venous catheter placement indications and patient selection.
