Low-dose tenecteplase during cardiopulmonary resuscitation in massive pulmonary embolism.

We report the case of an 18-year-old male who presented to the Emergency Department with sudden onset dyspnea. The patient was intubated on arrival, but suffered a cardiac arrest soon after. Point-of-care echocardiography during cardiopulmonary resuscitation revealed a grossly dilated right atrium and right ventricle, which alerted the Emergency physician to the possibility of massive pulmonary embolism leading to cardiac arrest. Due to no discernible history or risk factors in favour of pulmonary embolism, a decision was taken for thrombolysis with half dose Tenecteplase. Return of spontaneous circulation was achieved 14 min after thrombolysis, with massive pulmonary embolism subsequently being confirmed on CT Pulmonary Angiography.
