[Massive pulmonary embolism treated with selective infusion of tenecteplase].

Massive pulmonary embolism (PE) is a cardiovascular emergency due to a substantial obstruction of the pulmonary vascular bed, resulting in rapid right heart failure with a potentially fatal outcome.We present the case of a 50-year-old woman with massive PE and recent trans-sphenoid surgery because of pituitary adenoma. An occluding embolus, arising from deep venous thrombosis of the lower limbs, was demonstrated in the right pulmonary artery with selective angiography and treated with selective loco-regional infusion of low-dose tenecteplase.

An unpleasant surprise in the setting of primary percutaneous coronary intervention: diffuse and severe vessel ectasia with acute thrombosis of the distal right coronary artery in a patient with acute inferior myocardial infarction.

Coronary artery ectasia is defined as a > 1.5-fold dilation of the coronary artery compared to the diameter of adjacent normal segments. It must be distinguished from discrete aneurysms that appear in areas adjacent to coronary artery stenosis.
