From the Research
Duran venous stenosis is a condition characterized by the narrowing or constriction of veins, which can impede normal blood flow and lead to various complications, including post-thrombotic syndrome, as noted in studies such as 1.
Definition and Causes
Duran venous stenosis can develop in various veins throughout the body, including those used for dialysis access in patients with kidney disease. It often results from the formation of scar tissue or thickening of the vein wall, which reduces the vessel's diameter and restricts blood flow. The condition can be associated with the placement of central venous catheters and devices, as discussed in 2.
Symptoms and Diagnosis
Patients with Duran venous stenosis may experience symptoms such as:
- Swelling
- Pain
- A feeling of heaviness in the affected area In dialysis patients, it can lead to inadequate blood flow during treatments. Diagnosis typically involves imaging studies like:
- Ultrasound
- Venography
- MRI
Treatment Options
Treatment options for Duran venous stenosis include:
- Balloon angioplasty to widen the narrowed vein
- Stent placement to keep the vein open
- Surgical revision in severe cases Early detection and intervention are crucial to prevent complications such as complete vein occlusion or thrombosis, as highlighted in 3 and 4. Regular monitoring is recommended for high-risk patients, particularly those undergoing dialysis, to detect stenosis before it causes significant symptoms or complications.
Prevention and Management
Prevention of central vein stenosis is key to avoiding access failure and other complications, and relies upon avoidance of central vein catheter placement and timely placement of arteriovenous fistula in prospective dialysis patients, as noted in 2. The use of anticoagulation therapy, such as low-molecular-weight heparins (LMWHs) or direct oral anticoagulants (DOACs), can help prevent deep vein thrombosis and pulmonary embolism, as discussed in 1, 3, and 5.
