Large hematoma over the puncture site of percutaneous transluminal coronary angioplasty as a presenting sign of severe dengue infection.

Dengue fever is a common arboviral infection all over the world. It is endemic in the tropical and subtropical areas of the world with periodic epidemics in these areas. In its severe form dengue patients may develop life-threatening bleeding manifestations. We report here a case of large hematoma formation precisely located over the puncture site of percutaneous transluminal coronary angioplasty as a presenting sign of severe dengue infection for its unusual occurrence. <Learning objective: Severe dengue including dengue shock syndrome is a potentially life-threatening condition. Dengue virus-induced coagulopathy and thrombocytopenia may further complicate cardiological interventions like percutaneous transluminal coronary angioplasty or coronary artery bypass grafting as such patients are already on antiplatelet drugs. Performing any cardiovascular intervention in an endemic area of dengue needs proper vigilance to avoid such potentially life-threatening complications.>.
