Endovascular therapy of acute ischemic stroke by interventional cardiologists: initial national experience

OBJECTIVES
We report our initial experience with thrombectomy devices in patients with acute ischemic stroke.;

STUDY DESIGN
Demographic, clinical, and angiographic findings of 19 consecutive patients (7 females and 12 males; mean age 61.4±12.5 years) with acute ischemic stroke were evaluated retrospectively.

RESULTS
The mean initial National Institutes of Health Stroke Scale (NIHSS) score was 19.5±5.6. Middle cerebral artery was the occluded artery in all of the patients (proximal occlusion in 11, distal in 8 and tandem occlusions in 7 patients). Successful revascularization was achieved in 16 patients (84%). The mean NIHSS score was 8.4±8.2 at 24 hours after the procedure, and 60% of patients showed a modified Rankin scale score of ≤2 at 90 days. New occlusion by migrated emboli was observed in 2 (11%) cases. None of the patients had experienced post-procedural symptomatic intracerebral hemorrhage; 3 patients died during the three-month follow-up. In all patients, thrombectomy was performed with retrievable Solitaire AB stent system.

CONCLUSION
This single-center experience with mechanical thrombectomy devices demonstrated that high success rates can be achieved by experienced interventional cardiologists in equipped cath labs throughout the country.
