1072 A RARE CASE OF CONSTRICTIVE PERICARDITIS AFTER A STAB WOUND TO THE CHEST

Abstract

Abstract A 39 year old man presented to the emergency department with dyspnoea on exertion, chest pain and fatigue. Few years before, the patient was stabbed in the left chest thus developing Pneumothorax and mild pericardial effusion successfully treated with chest tube drainage and medical therapy. Physical examination revelead giugular vein distension and lower extremity edema. The echocardiographic evaluation showed typical signs of constrictive pericarditis which was confirmed by cardiac catheterization. Furthermore, because of clinical worsening and the absence of ongoing inflammation on PET-TC, the patient was referred to surgery. Pericardiectomy was successfully performed with rapid symptoms relief and clinical benefits. Histologic examination of pericardium showed the presence of thick fibrotic tissue with clusters of squamous epithelial cells with no cellular atypias or malignancy. Therefore, we hypothesize that following the chest stabbing wound, squamous and epitheloid cells have invaded the pericardial space producing a fibrotic reaction responsable of the development of the constriction. Furthermore multimodality imaging has been essential for diagnosis and management.
