| Abstract |
Objective
The new generation mechanical thrombectomy devices have been shown higher recanalization rates and better clinical results than the first generation. However, there still remains a significant subset of patients with unsuccessful recanalization despite multiple attempts. Recanalization with the Wingspan stent can be an option for treating acute ischemic stroke. This study was performed to report our single-center experience of Wingspan stent assisted recanalization in the treatment of acute ischemic stroke refractory to current mechanical thrombectomy devices.
Methods
We collected angiographic and clinical results of 11 patients with acute ischemic stroke undergone Wingspan stent (Stryker, Natick, MA, USA) assisted recanalization as a rescue procedure whose recanalization were not achieved with current mechanical thrombectomy devices such as Penumbra aspiration system (Penumbra, Alameda, California, USA) or Solitaire flow restoration stentriever device (ev3/Covidien Vascular Therapies, Irvine, CA, USA).
Results
Successful recanalization with the wingspan stent as a rescue procedure was achieved in 91% of the patients (82% thrombolysis in cerebral infarction grade 3 and 9% thrombolysis in cerebral infarction 2b). Nine patients (82%) showed neurological improvement on the NIHSS at discharge after the procedure and mean NIHSS improved from 11 (initial) to 4 (at discharge). Seven (64%) patients had good outcomes at 3 months after discharge. Neither intraprocedural complications nor symptomatic post procedural intracerebral hemorrhage was observed.
Conclusion
This study demonstrate that the Wingspan stent assisted recanalization for the treatment of acute ischemic stroke patients refractory to current mechanical thrombectomy devices can be a possible option as a rescue procedure. |
