Alveolar capillary dysplasia
Alveolar Capillary Dysplasia (pronunciation: al-vee-oh-lar cap-ill-air-ee dis-play-zee-uh) is a rare, congenital lung disorder that affects the development of the lungs' blood vessels and air sacs, or alveoli.
Etymology
The term "Alveolar Capillary Dysplasia" is derived from the Latin words alveolus meaning small cavity, capillaris meaning hair-like, and dysplasia meaning abnormal growth or development.
Definition
Alveolar Capillary Dysplasia (ACD) is a severe lung condition that is usually present at birth. It is characterized by abnormal development of the capillaries in the alveoli, which are the tiny air sacs in the lungs where oxygen is exchanged for carbon dioxide during respiration. This abnormal development leads to persistent pulmonary hypertension of the newborn (PPHN), which is a severe condition that causes high blood pressure in the lungs' blood vessels.
Symptoms
The symptoms of Alveolar Capillary Dysplasia typically appear shortly after birth and may include rapid breathing, difficulty breathing, and a blue coloration of the skin, lips, and nails due to a lack of oxygen in the blood (cyanosis). Other symptoms may include poor feeding and growth, and heart defects.
Diagnosis
Diagnosis of Alveolar Capillary Dysplasia is often made based on the presence of characteristic symptoms, a detailed patient history, and a thorough clinical evaluation. Specialized tests, such as a lung biopsy, may be necessary to confirm the diagnosis.
Treatment
Treatment of Alveolar Capillary Dysplasia is focused on managing the symptoms and complications of the condition. This may include oxygen therapy, medication to manage pulmonary hypertension, and in severe cases, a lung transplant may be considered.
