Pulmonary Vein Thrombosis: A Recent Systematic Review

Area of Science:

• Cardiology
• Pulmonology
• Vascular Medicine

Background:

• Pulmonary veins (PVs) are the primary source of arterial thromboembolism.
• Pulmonary vein thrombosis (PVT) is a rare, potentially lethal condition with unclear incidence.
• PVT commonly arises from malignancy, post-lung surgery, or atrial fibrillation, and can be idiopathic.

Purpose of the Study:

• To review the characteristics, diagnosis, and management of pulmonary vein thrombosis.
• To highlight the potential complications associated with delayed diagnosis of PVT.

Main Methods:

• Literature review of case reports and existing studies on PVT.
• Analysis of diagnostic imaging modalities used for PVT detection.
• Discussion of treatment strategies based on pathological findings.

Main Results:

• PVT often presents with nonspecific symptoms or remains asymptomatic.
• Diagnostic tools include transesophageal echocardiogram (TEE), CT scanning, MRI, and pulmonary angiography.
• Treatment options encompass antibiotics, anticoagulation, thrombectomy, and pulmonary resection.

Conclusions:

• Delayed PVT diagnosis can lead to severe complications, including pulmonary infarction, edema, heart failure, and systemic embolism.
• Prompt recognition and appropriate management are vital for improving patient outcomes.
