arteriographic blush
Persistent contrast staining in tissue indicating active extravasation or hypervascularity.
Full Definition
Arteriographic blush refers to the persistent accumulation of contrast material within tissues that appears as a hazy or cloud-like opacity during angiography. This finding typically indicates either active arterial bleeding (extravasation) or areas of increased vascularity such as tumors or inflammatory tissue. The blush pattern may be immediate or delayed and can help localize bleeding sources or characterize tissue perfusion abnormalities. Recognition of arteriographic blush is crucial for guiding interventional procedures, particularly in emergency settings where active hemorrhage requires immediate treatment.
Usage
Usage note: Distinguish between active extravasation blush and tumor blush based on clinical context.
