2024年4月4日 · Pulmonary veno-occlusive disease (PVOD) is considered an uncommon variant of primary pulmonary hypertension (PPH) that preferentially affects the postcapillary pulmonary vasculature. It is still controversial if this condition and pulmonary capillary haemangiomatosis (PCH) are varied expressions of the same condition or different entities.

Pulmonary veno-occlusive disease (PVOD) is a rare entity that is usually mistaken with pulmonary arterial hypertension (PAH) but is considered class I′ of PAH. It is important to subclassify PVOD and distinguish it from PAH as treatment with ...

Pulmonary veno-occlusive disease (PVOD), also known as “pulmonary arterial hypertension (PAH) with overt features of venous/capillary involvement”, is a rare cause of PAH characterised by substantial small pulmonary vein and capillary involvement, leading to increased pulmonary vascular resistance and right ventricular failure.

2021年7月15日 · Thin-section CT, a relatively specific test, plays an important role in the minimally invasive approach to PVOD diagnosis. Interlobular septal thickening and centrilobular ground glass opacities have been shown in several studies to be statistically significant features.

High-resolution computed tomography (HRCT) of the chest is a noninvasive diagnostic tool used to screen for PVOD. No HRCT data are available on SSc patients with precapillary PH. We undertook this study to evaluate the frequency and effect on prognosis of HRCT signs of PVOD in SSc patients with precapillary PH.

Pulmonary veno-occlusive disease (PVOD) and pulmonary capillary hemangiomatosis (PCH) are two unusual idiopathic disorders that almost uniformly manifest to the clinician as pulmonary arterial hypertension (PAH).

Swenson etal 11 reviewed CT findings on eight PVOD patients and foundthat smooth interlobular septal thickening, multifocal ground-glassopacities, pleural effusions, and enlarged central PAs were commonlyseen and were highly suggestive of PVOD.

Objective: The authors sought to evaluate the diagnostic accuracy of high-resolution computed tomography (HRCT) in the detection of pulmonary veno-occlusive disease (PVOD) in patients with pre-capillary pulmonary arterial hypertension (PAH) of unknown aetiology, and to identify the role of CT in diagnosis and therapy.

2013年12月3日 · The authors sought to evaluate the diagnostic accuracy of high-resolution computed tomography (HRCT) in the detection of pulmonary veno-occlusive disease (PVOD) in patients with pre-capillary pulmonary arterial hypertension (PAH) of unknown aetiology, and to identify the role of CT in diagnosis and therapy.

Pulmonary veno-occlusive disease (PVOD) is defined by specific pathologic changes of the pulmonary veins. A definite diagnosis of PVOD thus requires a lung biopsy or pathologic examination of pulmonary explants or postmortem lung samples. However, lung biopsy is hazardous in patients with severe pul …
