Preoperative scanning
Carotid Triplex high grade stenosis of internal carotid artery
MRA (magnetic res angiography)
Digital subtraction angiography (DSA)
CT csan
Μικροέμφρακτα βασικών γαγγλίων άμφω
MRI (magnetic res. imaging)
Huge right hemispheric infarct
Carotid stenting procedure
1st case
Initial angiographysevere internal carotid kinking (red arrow)
High grade ostial stenosis in internal carotid artery (κίτρινο βέλος)
Initially Cerebral protection device is deployed
Pre stenting angiographythe yellow arrow shows the stenosis to be dilated
Stent deployment
Post deployment we dilate the stent with a balloon
The stent is fully deployed
The carotid artery is now patent without residual stenosis. The kinking has not changed.
Initial angiography
Operative time 10 min
Final angiography
Crossing the lesion Cerebral protection filter
Stent deployment and balloon dilatation
Filter removal
Basic steps in carotid stenting
2nd case
Initial angiographysevere internal carotid kinking (red arrow)
High grade, long in length stenosis in internal carotid artery (κίτρινο βέλος)
Difficulty to pass the stent from the stenosis
Pre dilation with coronary balloon 3 χ 12 mm
Stent deployment (SE 6-8 x 40 mm)
Post deployment dilation with 5 Χ 30 mm balloon
Angiography after first post dilationthere is still a residual stenosis (red arrow)
2nd post dilation
Final angiography
