A subsegmental pulmonary embolism is a blood clot located on a distal, or distant and less central, branch of the pulmonary arteries. Treatment can depend on symptoms and risk factors. A ...

There was almost complete occlusion of the distal right main pulmonary artery and bilateral segmental and subsegmental pulmonary arteries that was consistent with thromboembolism. In the area of ...

This, in turn, improved the sensitivity of PE diagnosis by allowing high-quality workstations and more effective detection of perfusion defects in pulmonary arteries as small as 1 to 3 mm in diameter, ...

This led some to speculate that the subsegmental pulmonary arteries are supposed to contain clot and that we simply couldn't see it before now. If this theory is correct, the practice of providing ...

The best example is with pulmonary embolism (PE). As we go from the main pulmonary artery to the subsegmental pulmonary arteries, which are very small, you could diagnose a false-positive ...

Heparin was administered, and CT pulmonary angiography was performed later that ... multiple x-ray detectors to allow rapid imaging of smaller vessels (e.g., subsegmental arteries) and reduce motion ...

or central pulmonary embolism. Recurrent VTE occurred in four of 63 patients with subsegmental PE and in 37 of 623 of those with more proximal PE. In the group of patients with PE isolated to a single ...

A saddle pulmonary embolism is when a large blood clot gets stuck in the main pulmonary artery. It’s a type of pulmonary embolism (PE), which is a blockage in one of the arteries of the lungs.

It is caused by obstruction of the pulmonary arteries (from main to subsegmental levels) by pulmonary emboli that have not resolved but which have become organised. This causes narrowing of the ...
