What are the differential diagnosis for intraluminal filling defect in coronary angiogram ?
Posted Mar 07 2009 2:57pm
Intraluminal filling defect is often observed during coronary angiogram .Thrombosis has become the default diagnosis in most situations.This has resulted in over diagnosis of thrombosis .In fact a strategically located plaque stained by the dye is an equally common cause for intraluminal filling defect.
In fact there are many recognised caused of filling defect
An eccentric plaque
Dye trapped within plaque fissures
Calcification projecting into lumen
Plaque prolapse from stent struts
Artifacts-End on view of side branches
Static myocardial bridges
Trapped air bubble(Transient filling defect)
Streaming effect dye may mimic a filling defect
It is no t advicable to make a default dignosis of coronary thrombosis in all cases of intraluminal filling defects
