Delayed pericardial tamponade following central venous recanalization

Area of Science:

• Cardiovascular Medicine
• Interventional Cardiology
• Vascular Surgery

Background:

• Central venous occlusion, particularly at the superior vena cava-right atrium junction, presents a significant clinical challenge.
• Endovascular revascularization is a primary treatment modality for such occlusions.
• Potential complications, including vascular leakage and cardiac events, necessitate careful management.

Purpose of the Study:

• To describe the endovascular management of a patient with central venous occlusion.
• To detail the successful treatment of contrast agent leakage with a covered stent.
• To report and analyze the subsequent development and management of cardiac tamponade.

Main Methods:

• Endovascular revascularization was performed for superior vena cava (SVC) and right atrium junction occlusion.
• Contrast agent leakage during recanalization was managed with a covered stent.
• Cardiac tamponade was diagnosed via computed tomography (CT) and treated with pericardiocentesis.

Main Results:

• Successful revascularization and cessation of contrast leakage were achieved.
• Initial symptoms of facial swelling resolved post-procedure.
• Cardiac tamponade developed on day three, requiring drainage of pericardial effusion, leading to significant cardiovascular improvement.

Conclusions:

• Endovascular revascularization is effective for central venous occlusion.
• Covered stent deployment can manage contrast leakage during the procedure.
• Vigilant monitoring for delayed complications like cardiac tamponade is crucial after SVC revascularization.
