CTEPH
Also written as: CTEPH — Chronic Thromboembolic Pulmonary Hypertension
A form of pulmonary hypertension caused by chronic obstruction of pulmonary arteries by organized thromboembolic material.
Full Definition
Chronic Thromboembolic Pulmonary Hypertension (CTEPH) is a rare but potentially treatable cause of pulmonary hypertension characterized by chronic obstruction of pulmonary arteries by organized thromboembolic material and vascular remodeling. CTEPH can develop as a complication of acute pulmonary embolism when clots fail to resolve completely. Imaging plays a crucial role in diagnosis, with CT pulmonary angiography showing characteristic findings such as webs, bands, and chronic occlusions. Ventilation-perfusion scanning demonstrates mismatched perfusion defects. Early diagnosis is important because CTEPH may be curable with pulmonary thromboendarterectomy in appropriate candidates.
Usage
Usage note: Distinguish from acute PE and other forms of pulmonary hypertension in clinical documentation.
In Context
- "CTEPH was suspected based on persistent dyspnea and perfusion defects six months post-PE." — Clinical assessment
- "CT angiography demonstrated findings consistent with CTEPH including pulmonary artery webs and chronic occlusions." — Radiology report
