Results
MONTREAL SCALE
The main problem that can appear after an embolization is recurrence of an aneurysm.
The chance of recanalization grows when the coil density is not sufficient to induce a complete flow stasis and thrombus formation in the sac of an aneurysm.
To check the effectiveness of the procedure we used Montreal scale.
Analyzing post-treatment angiograms directly after the procedure of embolization,
we checked the degree of aneurysms occlusion.
In our study 76% of the patients that underwent the procedure achieved a complete obliteration of an aneurysm.

In 27 cases ( 45%) we were able to confirm the effect of the procedure 6 months after the embolization.
According to the Montreal scale,
81,8% of patients in the group achieved complete obliteration of the aneurysm,
4% was classified with a residual neck of the aneurysm and 12% with a residual aneurysm.
In our study the average size of an aneurysm was 8,5 mm (maximum: 26,5mm,
minimal: 2,5 mm).
During the procedure the average of 6 coils were used (maximum:12,
minimal: 2)
Most of the diagnosed aneurysms were located on the right Internal Carotid Artery.
The following table presents the locations of the aneurysms among our population.

COMPLICATIONS
After performing 72 embolizations,
we confirmedsubarachnoid hemorrhagein 18 cases (26%).
The following table presents complications that developed after procedures.
