[Hypertensive pulmonary vascular disease in children. Post-mortem study of 34 cases (author's transl)]
Insights
This study examined pulmonary hypertension in 34 infants, finding most cases linked to congenital heart defects. Lesions in pulmonary arteries and veins varied with age, highlighting disease progression.
Area of Science:
- Pediatric Pathology
- Cardiovascular Research
- Pulmonary Hypertension
Context:
- Pulmonary hypertension in infants is a critical condition.
- Congenital heart malformations are a significant cause.
- Post-mortem studies provide essential insights into disease pathology.
Purpose:
- To investigate the pathological findings of pulmonary hypertension in infants.
- To analyze macroscopic data and vascular lesions.
- To describe the evolution of hypertensive vascular disease with age.
Summary:
- A post-mortem study of 34 infants (16 days to 3 years) with pulmonary hypertension was conducted.
- 33 cases were associated with congenital heart malformations; one showed plexogenic arteriopathy.
- Macroscopic data (heart weight, ventricular wall thickness, pulmonary artery circumference) and vascular lesions in arteries and veins were analyzed.
- Patterns of hypertensive vascular disease and their age-related evolution were described.
Impact:
- Provides detailed pathological data on infant pulmonary hypertension.
- Enhances understanding of the link between congenital heart disease and pulmonary vascular changes.
- Offers insights into the morphological spectrum and progression of pulmonary hypertensive vascular disease in young children.
Abstract:
Report of a post-mortem study in 34 infants having presented pulmonary hypertension. Ages were between 16 days and three years old. One of the patients showed pulmonary lesion because of plexogenic arteriopathy of unknown etiology. The other 33 cases had congenital heart malformations. Macroscopic data as heart weight, thickness of the wall of the right ventricle and circumference of the pulmonary artery trunk were analized. Lesions developed in the pulmonary artery and its branches as well as those of the pulmonary veins are described. Different patterns of the hypertensive vascular disease are refered, emphasizing their evolution with the age of the patients. Some of the cases are particularly analized because of clinical, physiopathological or morphological peculiarities.
