Thoracic Central Vein Obstruction Endovascular Recanalization and Reconstruction

Area of Science:

• Vascular Medicine
• Interventional Radiology
• Cardiology

Background:

• Thoracic central vein obstruction (TCVO) compromises venous return from the upper body to the heart.
• Causes are benign or malignant, involving intraluminal, intramural, or extravascular obstruction.
• Often clinically referred to as superior vena cava syndrome.

Purpose of the Study:

• To review the diagnostic and therapeutic advancements in managing thoracic central vein obstruction.
• To highlight the efficacy and safety of endovascular therapy for TCVO.

Main Methods:

• Diagnostic evaluation typically involves ultrasound or venography (MR, CT, or catheter-directed).
• Treatment strategies include endovascular techniques such as thrombectomy, thrombolysis, recanalization, and stent or stent-graft placement.
• Pharmacological management with antiplatelet and anticoagulant agents is often employed post-procedure.

Main Results:

• Endovascular therapy has emerged as the preferred treatment for rapid and safe symptom alleviation.
• High technical and clinical success rates are reported for endovascular interventions.
• Major adverse events are infrequent, occurring in only 1%-2% of patients.

Conclusions:

• Endovascular therapy represents a safe and effective approach for managing thoracic central vein obstruction.
• The evolution of endovascular techniques has significantly improved patient outcomes for TCVO.
