What is bronchial artery hypertrophy?

Bronchial artery hypertrophy is one of the most frequent causes of haemoptysis in adults. It is linked to an increased diameter of the arteries due to chronic inflammatory lung pathology involving the bronchial wall and increasing the flow of bronchial arterial branches surrounding the pulmonary parenchyma.

Can a bronchoscopy detect sarcoidosis?

Bronchoscopy allows multiple diagnostic modalities in suspected sarcoidosis. Recent studies show sometimes surprising results, and the authors review the additive contributions of transbronchial lung biopsy, endobronchial biopsy, transbronchial needle aspiration, and bronchoalveolar lavage to diagnose sarcoidosis.

What causes bronchial artery hypertrophy?

There are several acquired diseases that can cause bronchial artery hypertrophy. Inflammatory diseases and infection, such as bronchiectasis (Fig. 6), cystic fibrosis (Fig. 7), tuberculosis (TB), or aspergilloma (Fig.

Where do bronchial arteries come from?

Bronchial Artery Origins. The bronchial arteries usually originate from the proximal descending thoracic aorta (Fig 1a–1c). They are termed orthotopic when they originate between the superior endplate of the T5 vertebral body and the inferior endplate of the T6 vertebral body.

What kind of doctor manages sarcoidosis?

Pulmonologist: is a doctor who specializes in the diagnosis and treatment of lung disorders and breathing problems. This is the doctor often seen by sarcoidosis patients because sarcoidosis affects the lungs in over 90% of patients. Pulmonologists can also treat asthma, COPD, cystic fibrosis and tuberculosis.

What virus causes sarcoidosis?

Sarcoidosis can often be difficult to diagnose and tricky to treat. The disease, which produces ball-like conglomerates of inflammatory cells called granulomas in the affected organs, looks likely to be caused by a bacterium called Propionibacterium acnes.

Is sarcoidosis a death sentence?

Sarcoidosis is not a death sentence! In fact, once diagnosed, your doctor’s first question will be to determine how extensive the disease is, and whether or not to treat at all – in many cases the choice will be to do nothing but watch carefully and allow the disease to go into remission on its own.

Is sarcoidosis a terminal illness?

For a small number of people, sarcoidosis is a chronic condition. In some people, the disease may result in the deterioration of the affected organ. Rarely, sarcoidosis can be fatal. Death usually is the result of complications with the lungs, heart, or brain.

How many patients with sarcoidosis have characteristic radiologic findings?

The HRCT appearance of pulmonary sarcoidosis varies greatly and is known to mimic many other diffuse infiltrative lung diseases. Approximately 60 to 70% of patients with sarcoidosis have characteristic radiologic findings. In 25 to 30% of cases the radiologic findings are atypical.

Where does progressive fibrosis in sarcoidosis cause volume loss?

Progressive fibrosis in sarcoidosis may lead to peribronchovascular (perihilar) conglomerate masses of fibrous tissue. The typical location is posteriorly in the upper lobes, leading to volume loss of the upper lobes with displacement of the interlobar fissure.

What are the different types of bronchial arteries?

Type 1 has one right bronchial artery and two left bronchial arteries, type 2 has one right bronchial artery and one left bronchial artery, and type 3 has two right bronchial arteries and two left bronchial arteries.

How often do patients with sarcoidosis go into remission?

Two third of patients have a remission within ten years. One third have continuing disease leading to clinically significant organ impairment. Less than 5% of patients die from sarcoidosis usually as a result of pulmonary fibrosis. These stages do not indicate disease chronicity or correlate with changes in pulmonary function.
