Under light microscopy, an obstructive thrombus consisted of red blood cells and fibrin net was observed in the control group; FAT were partially dissolved associated with small amount of red blood cells destruction in TUS group; recanalization was demonstrated in FAT in TUS + MB group, large amount of FAT was sonolysed, and the recanalized FA was collapsed with residual thrombus at the inner wall of FA (Figure 3(c)).
An obstructive thrombus consisted of red blood cells and fibrin matrix was observed (C1); small amount of red blood cells destruction was observed associated with partially dissolved FAT ((C2), black asterisk) at 30 min in TUS group; clots were sonolysed in large amount and the recanalized FA was collapsed with residual thrombus in the inner wall of FA ((C3), black asterisks).
Artifacts due to signal rephrasing may be difficult to distinguish from partly obstructive thrombus. With the second approach, time-of-flight MRV, a flow-sensitive sequence is used to image blood flow in the vein lumen.
