"Terminology "
"So far, periadventitial haematoma of the pulmonary arteries has been considered rare and is not often described. However, it seems to occur in 9-16% of patients with Stanford type A acute aortic dissection 1-4."
"Pulmonary artery periadventitial haematoma is characterised by haemorrhage around the wall of the main pulmonary artery and/or left and right pulmonary arteries. The pulmonary arteries and the aorta share a common adventitia, which constitutes a possible pathway for extravasation of blood in the setting of acute aortic dissection of the ascending aorta, where the posterior wall is affected or a traumatic thoracic aortic injury 1,2.

"Pulmonary artery periadventitial haematoma (PA-PH) is rare and is usually secondary to acute aortic syndrome (intramural haematoma, dissection or trauma), with rupture of the posterior wall of the ascending aorta into the common aortopulmonary adventitia, (shared sheath) 1-4."
"Symptoms are those of an acute aortic syndrome and include sudden onset of chest pain, dyspnoea and hypertension 2."
