Summary
Pulmonary endarterectomy offers a curative treatment for chronic thromboembolic pulmonary hypertension, significantly improving survival and functional status compared to lung transplantation. Early surgical intervention is recommended to prevent irreversible changes.
Area of Science:
- Cardiovascular Medicine
- Pulmonary Medicine
- Surgical Innovation
Background:
- Chronic thromboembolic pulmonary hypertension (CTEPH) is a serious condition often underdiagnosed.
- The thromboembolic nature of CTEPH is increasingly recognized, with advances in understanding its pathogenesis.
- Surgical options for CTEPH include lung transplantation and pulmonary endarterectomy.
Purpose of the Study:
- To review the pathophysiology of CTEPH.
- To discuss recent advances in the assessment and treatment strategies for CTEPH.
- To highlight pulmonary endarterectomy as the preferred curative treatment.
Main Methods:
- Review of current literature on CTEPH pathophysiology, diagnosis, and treatment.
- Analysis of surgical techniques and perioperative management for pulmonary endarterectomy.
- Evaluation of medical treatment options, including prostanoids and endothelin receptor antagonists.
Main Results:
- Pulmonary endarterectomy provides superior long-term survival and functional improvement over lung transplantation.
- Advances in diagnosis and surgical techniques have improved patient prognosis.
- CTEPH is more prevalent than previously thought and often remains underdiagnosed.
Conclusions:
- Pulmonary endarterectomy is a successful treatment when performed in specialized centers with a multidisciplinary team.
- Operability is influenced by pulmonary vascular resistance and irreversible vascular changes; early surgery is advised.
- Further research is needed to define the role of novel pharmacotherapies in conjunction with surgery for CTEPH.
