25 endovascular procedures were performed: 13 targeted thrombolysis and 12 mechanical thrombectomy.
During thrombolysis ReoPro (Abciximab) was used twice,
the rt-PA 11 times.
Mechanical thrombectomy was performed using a 7 Penumbra sets,
5 Solitaire FR sets.
Two times combination therapy (targeted thrombolysis and mechanical thrombectomy) was used (Table 3).
In three cases of the vascular spasm papaverine was applied.

Obstruction occurred most frequently in the middle cerebral artery (36%),
basilar artery (24%),
vertebral artery (12%) and internal carotid artery (12%) (Table 4).

We evaluated 19 patients with ischemic stroke who underwent invasive treatment.
Neurological status of patients before treatment,
assessed using the NIHSS scale,
ranged from 7 to 18 (mean 12.10,
SD ± 4.4).
The status of patients after treatment,
according to the NIHSS scale,
ranged from 0 to 15 with an average of 7.63 (SD ± 4.22).
However,
on the day of discharge from the hospital,
the status of patients,
was in the range of 0 to 13 with an average of 6.94 (SD ± 4.5).
(Table 5.2).
The mean time from symptom onset to recanalization was 370 minutes (with a range of 180 - 510 minutes).
The mean duration time of the procedure was 90 minutes (with a range of 30 - 230 minutes) and 45 minutes for efficient procedures.
94.74% of all patients had improved neurological status (assessed using the NIHSS scale) after treatment and the status level was maintained until the day of discharge.
76% of all procedures performed resulted in successful recanalization (TICI 2a,
TICI 2b/3) (Table 5.1),
thus succeeding to obtain blood flow through brain vessels in 78.95% of patients.
Among these,
clinical improvement in NIHSS was 93.33%.
(Table 5.3).

Mechanical thrombectomy treatment performed using the Penumbra system ended in the clearing of 42.86% of obstructed vessels,
the use of the Solitaire FR set was successful in 100%.
The overall efficiency of mechanical thrombectomy (Penumbra + Solitaire FR) was 66.67%.
The efficiency of targeted thrombolysis was 84.62% (Table 6).
