Abstract:
Pulmonary artery aneurysms (PAA) are rare. To date there are no cases in the literature describing formation secondary to oesophageal perforation. We present an unusual case of ruptured inflammatory segmental PAA. A patient with oesophageal squamous cell cancer presented with shortness of breath and sepsis following endoscopic dilatation of an oesophageal stricture. Imaging demonstrated oesophageal perforation and a pulmonary parenchymal collection containing an inflammatory PAA. Following initial conservative management, he then re-presented with haemoptysis secondary to PAA rupture. He was treated with embolisation using an Amplatzer® vascular plug (AVP) and went on to make an uneventful recovery.

Formation of the Platelet Plug
As the injured blood vessel contracts, endothelial cells undergo contraction, revealing collagen fibers in the basement membrane and underlying connective tissue. Furthermore, the plasma membrane of endothelial cells becomes adhesive, preparing the site for platelet adhesion. Platelets...
