Treatment of Pulmonary Veno-Occlusive Disease in Idiopathic, Heritable, or Connective Tissue Disease-Associated PVOD
Clinical Scenario
This protocol addresses patients with pulmonary veno-occlusive disease arising in one of three distinct settings: idiopathic origin with no identifiable external cause, a heritable (genetic) predisposition, or an underlying connective tissue disease. Recognising the specific aetiology shapes how urgently patients are evaluated and referred.
Idiopathic PVOD
Heritable PVOD
Connective tissue disease-associated PVOD
Treatment Approach
The structured regimen for this scenario centres on a specific surgical intervention that represents the only curative pathway currently available for PVOD — prompt referral for formal evaluation is a key early step in management.
The complete evidence-based regimen, including evaluation criteria, referral thresholds, and full management algorithm, is available via the structured protocol.
References
- There were some reports of the benefit of immunosuppressive agents in patients with idiopathic and heritable PVOD and patients with connective tissue disease-associated PVOD.
- A lung transplant is the only curative option.
- If suspected, these patients should be referred for lung transplant evaluation early in the course of the disease, as lung transplantation is the only therapy shown to increase life expectancy in patients with PVOD.
