Whether to dissolve the thrombus or not, whether to remove the thrombus or take other measures, all require waiting for the angiography results before considering.
Pulmonary embolism generally occurs in the main trunks of the left and right pulmonary arteries and their branches. Distal stubborn pulmonary embolism is relatively rare. Due to the strong self-dissolving ability of thrombosis in the terminal circulation of pulmonary arteries, small terminal thrombi can be completely self-dissolved by the body's vessels without the need for excessive thrombolysis by doctors. Doctors only need to unblock the main artery trunk.
With this guiding idea, it is akin to heart coronary angiography which targets the roots of major vessels. Doctors need to ensure the contrast agent reaches the root of the left and right pulmonary artery trunk, generally by injecting it into the inferior vena cava.
