Objective:
To determine the most optimal period of surgical treatment after previous stroke.
Material And Methods:
There were 186 patients with significant ICA stenosis and previous unilateral stroke for the period 2008-2014 at the Pletnev Hospital (Moscow). Surgical approach was used in 136 (73.1%) patients (group I), conservative treatment at the neurological department - in 50 (26.9%) patients (group II). We analyzed neurological and cognitive status in both groups, regression of symptoms depending on the period after stroke, early and long-term postoperative outcomes.
Results:
In early postoperative period, 7 (5.1%) cerebral ischemic events (transient ischemic attack (TIA) and stroke) occurred in the 1st group. No correlation of neurological complications and type of intervention was revealed. In long-term period, stroke occurred in 3.6% in the first group and in 14% in the second group over the same period. Surgical treatment was followed by more complete recovery of neurological functions (NIHSS score 6.2±0.5 versus 7.0±0.8; modified Rankin score 1.5±0.2 versus 2.1±0.5, p<0.05) and cognitive mechanisms (MoCA score 22.04±1.48 versus 20.04±1.48, p<0.05).
Conclusion:
Carotid endarterectomy and carotid artery stenting are effective for prevention of recurrent stroke. Carotid artery repair accelerates recovery of cognitive functions and regression of neurological symptoms in these patients.
