Major Complications of Deep Venous Stenting

Area of Science:

• Vascular Surgery
• Interventional Radiology
• Cardiovascular Medicine

Background:

• Deep venous stent placement is a primary treatment for venous obstruction.
• Existing complication data relies on limited case reports and single-center studies.
• Understanding complication incidence is vital for patient counseling and procedural optimization.

Purpose of the Study:

• To determine the incidence of serious complications associated with iliocaval and iliofemoral stent placement.
• To analyze major adverse events in a large, multi-center cohort.

Main Methods:

• Retrospective analysis of 1814 patients treated between January 2014 and September 2023.
• Inclusion of major complications: death, major bleeding, pulmonary embolism, reintervention, vessel rupture, acute kidney injury, and stent-related issues (crushing, fracture, migration, erosion).

Main Results:

• A total of 1814 patients underwent deep venous stent placement.
• The overall rate of major stent-related complications was 3.3% (61 patients).
• Most frequent complications included stent crushing (29.5%), fracture (16.4%), and erosion (13.1%); death occurred rarely (0.2%).

Conclusions:

• Deep venous stent placement demonstrates a favorable safety profile with low major complication rates.
• Operators must be aware of potential, albeit rare, complications to ensure fully informed patient consent.
