Interventional treatment for post-thrombotic chronic venous obstruction: Progress and challenges

Area of Science:

• Vascular Surgery
• Interventional Radiology
• Cardiovascular Medicine

Background:

• Chronic venous obstruction, including nonthrombotic iliac vein lesions and post-thrombotic syndrome (PTS), significantly impacts patient quality of life and healthcare costs.
• Minimally invasive endovascular techniques, such as venous recanalization and stenting, are increasingly utilized for treating PTS.
• Despite advancements, challenges remain in optimal patient selection, procedural execution, and ensuring long-term efficacy.

Purpose of the Study:

• To review and synthesize current knowledge on the interventional treatment of PTS.
• To discuss the evolution of endovascular techniques and stenting in managing chronic venous obstruction.
• To highlight key considerations for successful venous stenting procedures and long-term outcomes.

Main Methods:

• Comprehensive literature review of studies on endovascular treatment for PTS.
• Analysis of patient selection criteria for venous recanalization and stenting.
• Evaluation of procedural techniques, stent characteristics, and anatomical factors (e.g., inflow).

Main Results:

• Endovascular stenting has shown promise in treating PTS, offering a less invasive alternative to open surgery.
• Dedicated venous stents and refined techniques have improved procedural success rates.
• Careful patient selection, attention to anatomical details, and appropriate postoperative management are crucial for optimal long-term results.

Conclusions:

• Interventional treatment, particularly venous stenting, is a viable option for selected patients with PTS.
• Continued research and refinement of techniques are essential to further optimize long-term outcomes.
• A multidisciplinary approach considering patient anatomy and postoperative care is key to successful venous stenting.
