| 1) Thrombus in CFV: Here is a huge
thrombus in CFV (freen arrow), the thrombus is seen in
the greater saphenous vein too (red arrow), this
thrombus extends superiorly...thrombi that cross the
saphenous opening are the most dangerous. Note that
there is no flow around the thrombus. |

| 2) Flow around thrombus: There is
blood flow around the thrombus, a findingseen with
resolving thrombi where clot retraction has taken place. |

| 3) Chronic thrombus: Acute thrombi
will distend the veins and they will appear fat, with
chronicity, the thrombi retract and become thinner and
the vein does too... |

| 4) Positive distal augumentation: a
short-cut to detect patency of veins is the distal
augumentation manouver, probe placed on the upper sfv,
calf compressed... normally the flow should show a spike
indicating patent veins between the two sites. |

| 5) Negative distal augmentation: if
there is an obstruction in between, the distal
augmentation will not show any spike. |
