Summary
This report explores the application of iliocaval junction reconstruction techniques in patients with inferior vena cava (IVC) obstruction. It compares different reconstruction methods, particularly the jump stent and double-barrel techniques, discussing their clinical outcomes and the impact of renal vein coverage on kidney function. The study suggests that, under appropriate conditions, the jump stent technique is a cost-effective option, while the double-barrel technique is recommended for more complex cases.
Introduction
IVC obstruction is a rare but severe vascular condition, often accompanied by iliac vein confluence stenosis or occlusion. The primary goal of treatment is to restore venous flow, and due to the anatomical complexity of the area, various techniques have their specific indications and limitations. This report analyzes key reconstruction techniques and provides optimal treatment recommendations.
Surgical Preparation and Assessment
•Positioning and Preoperative Preparation:
•Due to the complexity of iliocaval junction surgeries, precise positioning and preoperative planning are critical for success, especially when considering venous stent placement. Lateral view imaging is crucial to avoid spinal canal injury .
Jump Stent Technique
•Advantages of the Jump Stent Technique:
•The jump stent technique is an effective strategy, particularly suited for cases not requiring continuous stent coverage. It reduces the amount of stent material used, shortens procedure time, and lowers costs. It also prevents stent competition, ensuring smooth blood flow.
•Clinical Cases:
•Clinical cases using the jump stent technique for iliocaval junction reconstruction showed favorable outcomes, with rapid patient recovery and low complication rates.
Double-Barrel Technique
•Application of the Double-Barrel Technique:
•This technique is ideal for managing complex iliocaval junction lesions. By using two parallel stents, it ensures unobstructed blood flow and minimizes the risk of stent geometry deformation. However, the increased material cost and potential issues with neointimal hyperplasia should be considered.
•Limitations:
•While the double-barrel technique has benefits for complex cases, the additional stent material and risk of “dead space” formation require careful management.
Conclusion
1. Reconstruction techniques for the iliocaval junction in IVC obstruction patients show promising results.
2. The jump stent technique is a cost-effective treatment option, especially for patients not requiring full stent coverage.
3. The double-barrel technique is suitable for complex iliac vein lesions but requires further study to reduce its limitations, particularly regarding stent material and neointimal hyperplasia issues.
