Results
The presence of hyperdensities on CT after intraarterial thrombolysis is not always bleeding,
because there may be extravasation of contrast. However,
this may suggest some degree of microvascular damage and may predict the onset of further bleeding complications.
In the three cases reported,
two of them showed extravasation and the other cerebral hemorrhage.
PATIENT 1: At 17 hours,
thrombolysis was performed.
CT showed right basal ganglia hyperdensity,
poorly defined (Figure 9).
This hyperdensity was practically resolved on the control CT performed after 48 hours,
ensuring the results were free of contrast extravasation (Figure 10).
Patient 2: At 24-hours intra-arterial thrombolysis was performed.
CT showed right basal ganglia hyperdensity of 2.2 cm with perilesional edema (Figure 11) and left occipital horn hyperdensity with mass effect on frontal horn of the right lateral ventricle,
these hyperdensities were related to cerebral hemorrhage in the basal ganglia (Figure 12).
Patient 3: At 24-hours intra-arterial thrombolysis was performed.
CT showed linear hyperdensity on distal M1 segment (Figure 13) which is continuous with adjacent hyperdensity of Sylvian fissure and minimal hyperdensity of the left basal ganglia (Figure 14 ) probably related to contrast extravasation.
