Serial long-term phlebography after documented lower leg thrombosis

Area of Science:

• Vascular Medicine
• Radiology
• Pathology

Background:

• Deep vein thrombosis (DVT) can lead to long-term venous damage.
• Understanding the phlebographic appearance of post-thrombotic veins is crucial for patient management.

Purpose of the Study:

• To describe the phlebographic findings in patients following deep vein thrombosis.
• To correlate phlebographic results with the extent and location of the initial thrombotic event.

Main Methods:

• Retrospective analysis of 86 phlebograms from 38 patients.
• Follow-up duration ranged from 2 weeks to 6 years post-thrombosis.
• Phlebographic patterns were assessed for vein clearance, occlusion, and structural restoration.

Main Results:

• Veins cleared earliest and most completely in calf-limited thrombosis.
• Totally occluded veins showed slower and less complete clearance compared to partially occluded or non-occluded veins.
• Post-thrombotic restoration of normal venous and valvular structures was frequently observed.

Conclusions:

• Phlebography is valuable in assessing DVT outcomes.
• Vein recanalization and structural repair are common sequelae of DVT.
• Observed phlebographic patterns correlate with pathological findings of intimal thickening post-thrombosis.
