Elevated d-dimer after surgery may be due to hypercoagulable state of blood due to surgical trauma, prolonged postoperative bed rest, and so on.
d Dimer is a specific product of degradation of cross-linked fibrin by fibrinolytic enzymes during the coagulation process, and is a commonly used indicator for monitoring blood clots with high sensitivity but poor specificity.
After surgery, the body will bleed due to surgical trauma, leading to the activation of the body’s coagulation and fibrinolytic system, which in turn causes the elevation of d-dimer, but this does not suggest that the body has deep vein thrombosis.
Postoperative bed rest and inability to move normally can lead to reduced mobility of both lower extremities and slow blood flow, which may trigger deep vein thrombosis.
The specificity of d-dimer is poor, thrombosis, inflammation, trauma, tumors, etc. may lead to its elevation, need to further improve the examination under the guidance of the physician, to be identified.
